The Gathering Climate Storm and the Media Cover-up | By Dr. Andrew Glikson

“Earth is now substantially out of energy balance. The amount of solar energy that Earth absorbs exceeds the energy radiated back to space. The principal manifestations of this energy imbalance are continued global warming on decadal time scales and continued increase in ocean heat content.” (James Hansen 2018)

“The people have no voice since they have no information” …“No First World country has ever managed to eliminate so entirely from its media all objectivity – much less dissent.” (Gore Vidal)

With the exception of the few who comprehend the nature of a Faustian Bargain[1], some billionaires, captains of industry and their political and media mouthpieces are driving humanity toward self-destruction through the two biggest enterprises on Earth, the fossil fuel industry, which is devastating the Earth atmosphere, and the industrial-military machine leading toward nuclear war. The rest of the world is dragged subconsciously, induced by bread and circuses.

[ 1880 - Feb. 2016 temperature anomaly from 1951-1980, source ]
By close analogy with the tobacco denial syndrome[2], albeit with consequences affecting the entire Earth, the fossil fuel industry has been paying climate pseudoscientists to propagate fabricated untruths regarding the origins and consequences of global warming, widely disseminated by the media.

Despite irrefutable evidence for global warming, such fabrications are still quoted by pro-coal lobbies and compliant politicians, including:
  1. Denial of basic laws of physics, i.e. the blackbody radiation laws of Plank, Stefan-Boltzmann and Kirchhoff[3]
  2. Denial of direct observations and measurements in nature, in particular the sharp rises of temperatures, ice melt rates, sea level rise and extreme weather events.
  3. Denial of the global warming origin of extreme weather events, i.e. the closely monitored rise in storms, hurricanes, fires and droughts in several parts of the world.[4]
  4. Denial of the bulk of the peer-reviewed literature summed up in the IPCC reports.
  5. Denial of conclusions of the world’s premier climate research organizations (NASA, NOAA, NSIDC (National Snow and Ice Data Centre), Hadley-Met, Tindale, Potsdam, WMO (World Meteorological Organization), CSIRO, BOM and other organizations).
In view of the rapidly growing direct evidence from the increase in extreme weather events, the common tactic has changed from outright denial to a minimization of the significance and consequences of the shift in state of the climate.

READ MORE: Crimes Against the Earth

Whereas news items channeled by international news agencies regarding extreme weather events are generally reported, at least by national broadcasters, the plethora of discussion and debate programs on TV and radio stations mostly overlook the enhanced toxic effects of carbon gases[5], or relegate it behind sports and entertainment news. In most instances discussion panels focus on the inside political machinations rather than the critical issues themselves.

According to Mary Debrett[6]:
“We are now in the middle of perfect storm of miscommunication about climate change. Various factors have converged to confound rational public conversation. Public opinion polling indicates that although there is widespread acceptance of climate change resulting from human activities, the public’s preparedness to pay for action to mitigate climate change is actually declining – even as climate scientists warn of the increasing urgency for action. These results signal a serious problem in the public communication of climate change. They reflect this perfect storm – where tensions between the media, politicians and various lobby groups have made it impossible for scientists and others with appropriate expertise, to cut through.”
The major influence the media exerts on public opinion[7], and the extent to which it can be referred to as the “tail which wags the political dog”, allows it nearly as much, or more, political power as political leaders, chief bureaucrats and heads of corporation. A power accompanied with little responsibility.

Hurricane Nate Threatens New Orleans

The image below, a forecast for October 8, 2017, run on October 7, shows Hurricane Nate near New Orleans, with winds as fast as 83 mph or 134 km/h (at 850 mb) and up to 5.33 in or 135.4 mm (3-hour precipitation accumulation) of rain (at the green circle).


Early forecast also showed as much as 6.1 in or 154.9 mm of rain (3-hour precipitation accumulation) hitting the Mississippi coast.

The NOAA image below also shows the track over North America as forecast over the next few days.


Nate, the fourth major storm to strike the United States in less than two months, killed at least 30 people in Central America before entering the warm waters of the Gulf and bearing down on the U.S. South (Reuters report).


One of the biggest dangers is storm surge flooding, as illustrated by above image and the tweet below.


As the world keeps warming, hurricanes are increasingly causing damage, as also discussed in a recent post.

The situation is dire a calls for comprehensive and effective action, as described at the Climate Plan.

Rain Over Arctic Ocean

It's raining over the Arctic Ocean and the rain is devastating the sea ice. What are the conditions that led to this?

As has been known for a long time, energy is added to Earth due to emissions by people and this translates into a warmer troposphere with more water vapor, warmer oceans and stronger winds.

Warming is hitting the Arctic particularly hard, due to numerous feedbacks, as illustrated by the sea surface temperature anomalies image on the right.

On July 6, 2017, cyclonic winds lined up to create a 'perfect storm'. As a result, an Atmospheric River of moisture was driven through Bering Strait into the Arctic Ocean, as shown on the images below.


On July 6, 2017, 1500 UTC, winds in Bering Strait were as high as 58 km/h (36 mph) at surface level (green circle on above image left), and as high as 82 km/h (51 mph) at 850 mb (green circle on above image right).

On July 6, 2017, surface temperatures of the air in Bering Strait were as high as 8.1°C (46.5°F) (green circle on image right).

Another indication of the strength of the wind driven through Bering Strait is wave height. On July 6, 2017, waves were as high as 3.35 m or 11 ft in the Bering Strait, at the location marked by the green circle on the image on the right.

The relatively warm and moist air driven through Bering Strait by strong winds is causing rain to fall over the sea ice of the Arctic Ocean, as shown on the video and images further below.

On July 7, 2017, high air temperatures were recorded over land and over the water.

The image below shows temperatures recorded at two locations over the Mackenzie River, one of 32.6°C or 90.8°F at the mouth of the Mackenzie River and another one of 34.7°C or 94.5°F further inland. Warm water from rivers can substantially warm up the sea surface and thus melt the sea ice.

Temperature of the surface of the water was 10°C or 50.1°F where the water was pushed into the Bering Strait, while temperatures as high as 46.9°C or 116.3°F were recorded over California.


The combined impact of high temperatures, strong winds, high waves and warm river water, rain water and melt water looks set to further devastate what sea ice is left in the Arctic Ocean.

Rain can be particularly devastating. The very force at which rain strikes can fracture the sea ice where it's weak, while pools of rainwater and meltwater will form at places where the sea ice is stronger. Where fractures appear in the sea ice, warm water can reach further parts of the ice and widen the cracks.

The video below shows rain over the Arctic Ocean. The video was created with cci-reorganizer.org forecasts from July 3, 2017, 18:00 UTC to July 17, 2017, 00:00 UTC.


Arctic sea ice is in a terrible shape. Sea ice volume is at a record low, as indicated by the Wipneus image below showing volume anomalies from 2002.
The image below, by Torstein Viddal, shows how low the 2017 year-to-date average sea ice volume is.


An additional danger is wildfires. Due to high temperatures, wildfires have broken out near the Mackenzie River, as illustrated by the satellite image below.


Wildfires come with a lot of emissions, including soot that darkens the surface when settling down, thus further speeding up warming.

The situation is dire and calls for comprehensive and effective action as described at the Climate Plan.

Warning of mass extinction of species, including humans, within one decade


[ click on images to enlarge ]
On February 10, 2017, 18:00 UTC it is forecast to be 0.1°C or 32.1°F at the North Pole, i.e. above the temperature at which water freezes. The temperature at the North Pole is forecast to be 30°C or 54°F warmer than 1979-2000, on Feb 10, 2017, 18:00 UTC, as shown on the Climate Reanalyzer image on the right.

This high temperature is expected as a result of strong winds blowing warm air from the North Atlantic into the Arctic.

The forecast below, run on February 4, 2017, shows that winds as fast as 157 km/h or 98 mph were expected to hit the North Atlantic on February 6, 2017, 06:00 UTC, producing waves as high as 16.34 m or 53.6 ft.


A later forecast shows waves as high as 17.18 m or 54.6 ft, as illustrated by the image below.


While the actual wave height and wind speed may not turn out to be as extreme as such forecasts, the images do illustrate the horrific amounts of energy contained in these storms.

Stronger storms go hand in hand with warmer oceans. The image below shows that on February 4, 2017, at a spot off the coast of Japan marked by green circle, the ocean was 19.1°C or 34.4°F warmer than 1981-2011.


As discussed in an earlier post, the decreasing difference in temperature between the Equator and the North Pole causes changes to the jet stream, in turn causing warmer air and warmer water to get pushed from the North Atlantic into the Arctic.

The image below shows that on February 9, 2017, the water at a spot near Svalbard (marked by the green circle) was 13°C or 55.3°F, i.e. 12.1°C or 21.7°F warmer than 1981-2011.

[ click on images to enlarge ]
Warmer water flowing into the Arctic Ocean in turn increases the strength of feedbacks that are accelerating warming in the Arctic. One of these feedbacks is methane that is getting released from the seafloor of the Arctic Ocean. Update: The image below shows that methane levels on February 13, 2017, pm, were as high as 2727 ppb, 1½ times the global mean at the time.

[ click on image to enlarge, right image added for reference to show location of continents ] 
What caused such a high level? High methane levels (magenta color) over Baffin Bay are an indication of a lot of methane getting released north of Greenland and subsequently getting pushed along the exit current through Nares Strait (see map below). This analysis is supported by the images below, showing high methane levels north of Greenland on the morning of February the 14th (left) and the 15th (right).



The image below shows methane levels as high as 2569 ppb on February 17, 2017. This is an indication of ocean heat further destabilizing permafrost at the seafloor of the Laptev Sea, resulting in high methane concentrations where it is rising in plumes over the Laptev Sea (at 87 mb, left panel) and is spreading over a larger area (at slightly lower concentrations) at higher altitude (74 mb, right panel).


This illustrates how increased inflow of warm water from the North Atlantic into the Arctic Ocean can cause methane to erupt from the seafloor of the Arctic Ocean. Methane releases from the seafloor of the Arctic Ocean have the potential to rapidly and strongly accelerate warming in the Arctic and speed up further feedbacks, raising global temperature with catastrophic consequences in a matter of years. Altogether, these feedbacks and further warming elements could trigger a huge abrupt rise in global temperature making that extinction of many species, including humans, could be less than one decade away.

Without action, we are facing extinction at unprecedented scale. In many respects, we are already in the sixth mass extinction of Earth's history. Up to 96% of all marine species and 70% of terrestrial vertebrate species became extinct when temperatures rose by 8°C (14°F) during the Permian-Triassic extinction, or the Great Dying, 252 million years ago.

During the Palaeocene–Eocene Thermal Maximum (PETM), which occurred 55 million years ago, global temperatures rose as rapidly as by 5°C in ~13 years, according to a study by Wright et al. A recent study by researchers led by Zebee concludes that the present anthropogenic carbon release rate is unprecedented during the past 66 million years. Back in history, the highest carbon release rates of the past 66 million years occurred during the PETM. Yet, the maximum sustained PETM carbon release rate was less than 1.1 Pg C per year, the study by Zebee et al. found. By contrast, a recent annual carbon release rate from anthropogenic sources was ~10 Pg C (2014). The study by Zebee et al. therefore concludes that future ecosystem disruptions are likely to exceed the - by comparison - relatively limited extinctions observed at the PETM.

An earlier study by researchers led by De Vos had already concluded that current extinction rates are 1,000 times higher than natural background rates of extinction and future rates are likely to be 10,000 times higher.

from the post 2016 well above 1.5°C
As above image shows, a number of warming elements adds up to a potential warming of 10°C (18°F) from pre-industrial by the year 2026, i.e. within about nine years from now, as discussed in more detail at the extinction page.


Above image shows how a 10°C (18°F) temperature rise from preindustrial could be completed within a decade.

More than 2.5m Sea Level Rise by 2040?

A warming period more than 400,000 years ago pushed the Greenland ice sheet past its stability threshold (which may have been no more than several degrees above pre-industrial temperatures). This resulted in a nearly complete deglaciation of southern Greenland, raising global sea levels some 4.5-6 meters, found a recent study by Reyes et al. Due to melting elsewhere, global mean sea level then was 6 to 13 metres above the present level. Indeed, melting of the entire West Antarctic Ice Sheet can add a further 6-meter rise in sea levels. If the East Antarctic Ice Sheet (EAIS) were to melt as well, sea levels would rise by around 70 metres.

Sea level is now rising by 3.1mm (0.122 inch) per year. Much of this rise is due to rising temperatures, but there are also other factors. One quarter of the rise results from groundwater depletion, while run off from melting ice and glaciers adds another quarter and the remainder is attributed to thermal expansion of sea water. Furthermore, as temperatures rise, feedbacks start to kick in, e.g. the kinetic energy from stronger waves and more intense storms can speed things up.

Clearly, a rapid multi-meter rise would be devastating as it would flood many coastal cities, as well as much of the land now used to grow food. By how much have sea levels been rising recently and how fast can they be expected to rise in the near future?
NASA image, data by the JPL PODAAC, in support of the NASA's MEaSUREs program.
Sea levels have risen by some 60 mm over the past 20 years, as above NASA image shows, which has a linear trendline added. The question is whether a linear trendline is the most appropriate trendline, given that it suggests that a similar rise could be expected over the next 20 years. A polynomial trendline appears to fit the data better, as the animation below shows.


Such a polynomial trendline, however, points at a similar rise (of some 50 mm) in just four years time, with an even more steeper rise to follow, as illustrated by the image below.


And indeed, such a rise doesn't slow down there. A polynomial trendline applied to the data points at a sea level rise of more than 2.5 m (8.2 ft) by the year 2040.



The image below gives an idea of what a sea level rise of six feet (1.829 m) would do to the City of New York. Of course, this is only the sea level rise. Storm surge would come on top of this, as discussed at Ten Dangers of Global Warming.



So, what would be more appropriate, to expect sea levels to continue to rise in a linear way, or to take into account feedbacks that could speed things up? Where such feedbacks could lead to is illustrated by the image below.

This calls for comprehensive and effective action, as discussed at the Climate Plan blog.

The Great Arctic Flush

By Paul Beckwith

A massive cyclone is forecast to develop in the Arctic, as shown on the image below, from the Naval Research Laboratory.

Within 2 weeks the Arctic Ocean will be completely transformed. The cyclone that appears 6 days out on both the US and European ten day forecasts will massacre the sea ice in what I call "The Great Arctic flush".

The image below is a forecast for Arctic sea ice speed and drift on July 27, 2013. More images, including animations, on Arctic sea ice can be viewed at http://www7320.nrlssc.navy.mil/hycomARC/arctic.html 


Last August, a massive cyclone formed over the Arctic Ocean and destroyed 800,000 square km of ice in about a week. The predicted cyclone looks to be as strong as the one in early August, 2012. Problem is, the ice is much weaker, thinner and fractured this year; including all the ice just north of the Canadian Arctic Archipelago that is 4 or 5 meters thick; this ice is mobile, broken, fractured ice piled up into ridges; it is not multiyear ice (MYI) at all.

Above image, from the Naval Research Laboratory is a prediction of ice speed and drift a week from now, showing the motion of the ice, the darker and redder the faster, the ice is being set in motion by the cyclone above. Since the Coriolis force flings things to the right, the ice is all sent to the outside of the rotation, into the warmer surrounding water as well as the Atlantic Ocean. The storm surge of a foot or two over the entire basin (highest near the cyclone eye) will draw in warm water from the Pacific via the Bering Strait and from the Atlantic via the Fram Strait. It will also mix the fresh water on the surface from melting ice with warmer saltier water from below. It will also generate lots of churning and grinding of the ice and waves several meters high. Warm and smoky air that is filled with ash and black carbon from burning fires in the far north will drop the albedo of the ice and increase the solar absorption. 

When I forecast zero sea ice at the end of the melt season this summer, I fully expected at least one or more of these massive cyclonic storms. Last year it occurred in early August, and lasted for about 8 days. In the rest of the melt season last year no other huge cyclone developed, although several small ones did. Perhaps the cyclone disturbed the ocean conditions enough to prevent subsequent ones occurring. We shall see this year...

The Growing Threat of Catastrophic Storm Surge in the Next 30 Years on a Fast, Global Warming Induced, Sea Level Rise and its Consequences for Coastal Cities and Humanity

By Malcolm P.R. Light
November 11, 2012

Abstract

Methane is erupting as widespread torches and fountains in the Arctic ocean up to 1 km across and is exponentially increasing in concentration in the Arctic atmosphere (Shakova et al. 2008 and 2010; Light and Carana 2012; Light 2012). The Arctic atmospheric methane is mostly derived from Arctic subsea shelf and slope methane hydrates due to their destabilization by globally warmed Gulf Stream currents which enter the Arctic west of Svalbard and through the Barents Sea. In the North Atlantic, the surface of the Gulf Stream is heated in the summer and is marked by excessive evaporation due to the global warming effects of pollution clouds emanating from North America (Figure 5; IPCC Working Group 1. Fig. 10.12 Lavatus Prodeo, 2012).
The exponential increase in Arctic atmospheric methane has caused an exponential decrease in the volume of Arctic sea ice and in the continent wide reflectivity (albedo) of the Greenland ice cap (Light 2012; NASA Mod 10A1 data, from Carana, 2012). The atmospheric Arctic methane which is almost half the density of air is rising like hydrogen into the Stratosphere where it is forming and all encompassing global warming veil further aggravating the global warming of the lower level greenhouse gas clouds.

The ice melt back curves from the oldest lower 5* year old ice to the youngest shallowest 2 and 1 year old ice are caused by the progressive increase in temperature of the Gulf Stream “Atlantic Waters” which are entering the Arctic beneath the ice and melting it from the bottom up. The heating of the Gulf Stream waters is directly linked to the global warming of the North Atlantic caused by green house gas pollution blowing east off North America.

Above summary diagram (Figure 15, click on image to enlarge) shows all the determined global warming temperature curves and the latest "Sandy" storm surge curve based on a mean storm surge of 14 feet added to the mean latent heat of ice melting curve (Light 2012; Fichetti, 2012). All the global warming curves converge on a region between 2034 and 2052 where the mean atmospheric temperature anomaly will be greater than 8°C and all of the Earth's ice caps will have melted with a consequent sea level rise of 68.3 m (224 feet) above mean sea level (Wales, 2012). In particular the accelerated global warming curve from Carana (2012) and the "Sandy" storm surge curve converge on the mean atmospheric temperature extinction point derived from 20 estimates (Light 2012). This gives great confidence in the interpretation that we can expect catastrophic climate change from methane induced global warming between 2034 and 2052 unless humanity sharply cuts back some 90 to 95% on global greenhouse gas emissions and converts all its energy resources to renewable energy/ nuclear power.

A series of progressive extinction zones have been determined (after Parry et al. 2007) and include:-
  • Bleaching of most corals when the atmospheric temperature anomaly is between 1 and 2°C
  • Extreme droughts will extend over 1 - 30% of the land area when the atmospheric temperature anomaly exceeds 2°C which will make more than 1.8 billion people water stressed.
  • Widespread coral mortality will occur when the mean atmospheric temperature anomaly is between 2.5°C and 3.5°C and will be associated with a massive increase in the ferocity of tropical cyclones/hurricanes far in excess of the Sandy super storm.
  • Complete deglaciation and coastal inundation is expected when the mean atmospheric temperature anomaly increases from 4 to 8°C with a consequent sea level rise of some 68.3 metres (224 feet) above sea level. There will be major global extinction over this temperature interval as cereal production sharply decreases outside of the tropics.
Super storm Sandy has shown that Manhattan is already open to storm surge flooding and by 2016 when the Arctic Ocean begins to be free of ice, we can expect more violent hurricanes bearing down on the eastern coastline of the United States and increasing catastrophic damage to the coastal cities there.

The Alamo Project is a call for United States scientists and engineers to volunteer to develop a system of destroying the fast growing methane clouds in the atmosphere by radio/laser means or other processes before they destroy us. See this page:-
http://www.facebook.com/AlamoProject

Immediate and concerted action must be taken by governments and oil companies to depressurize the Arctic subsea methane reserves by extracting the methane, liquefying it and selling it as a green house gas energy source (see the ANGELS Project). See this post:-
http://arctic-news.blogspot.com/2012/06/angels-proposal.html

If greenhouse gas emissions are not sharply curtailed by 90% to 95% and the Arctic subsea and atmospheric methane extracted and destroyed, mean rising sea levels will breach the Thames Barrier by 2029 flooding London and the proposed Verrazano Narrows barrier in New York by 2030. The base of the Washington Monument (D.C.) will be inundated by 2031. By 2051, total global deglaciation will finally cause the sea level to rise up the lower 35% of the Washington Monument and humanity will have been eliminated by worldwide flooding and firestorms.

Hurricane Sandy intensifies climate change debate

By Dorsi Diaz

Although recent polls show that 70% of people now believe in climate change, recent extreme weather events are sure to drive that number even higher. With the East Coast of the U.S. reeling from the extreme devastation of Hurricane Sandy, attention has been brought back to what caused the Superstorm and why.

Many in the scientific community point to climate change as being a major contributing factor in the unprecedented storm.

Paul Beckwith, climate scientist at The University of Ottawa and member of the Sierra Club Canada, goes into detail in explaining how Hurricane Sandy was fueled by climate change:
“Rising greenhouse gases are rapidly warming our climate with Arctic amplification by 5x due to darkening from sea ice and snow cover collapse. The resulting decrease in temperature gradient between the equator and Arctic slows the jet stream winds which increases their waviness in the north/south direction. Combined with 4% higher water vapor in warmer atmosphere, this waviness makes storms more intense and frequent and larger in size and occur in different places. It made Sandy enormous in size and made her turn left onto the U.S. coast instead of turn right like every other hurricane in history.”

In a comment to Dorsi Diaz, reporter for the Examiner, Beckwith goes on to explain what would have happened had Sandy not been influenced by the climate anomalies that fed into the storm:
“Without the blocking high pressure northward and low pressure trough pulling her to the coastline (from the jet stream waviness) she would have headed harmlessly out to sea. Without the huge waviness of the jets the massive and ongoing drought in the U.S. would not be occurring. As sea ice further declines these storms and drought and all extreme weather events are certain to explode in magnitude, size, and frequency.”

According to Sam Carana, AMEG member (Arctic Methane Emergency Group) and editor of the Arctic-News blog:
“Warming in the Arctic is accelerating at a pace several times that of the rest of the world. This is changing the jet stream, which is what forced Sandy to move inland, to spread out and to hang around for such a long time. Without more effective action on climate change, weather events like this can be expected to hit the U.S. more often and with increasing force in future.”

Although some die-hard climate skeptics say that Hurricane Sandy was not caused or fueled by climate change, that minority seems to be losing ground as evidence piles up in favor of those that believe that extreme weather events are being caused by a warming climate.

Nathan Currier, senior climate advisor for Public Policy Virginia, who also writes about climate change, had this to say about it in a recent article:
“All major components of this super storm show the signature of human-induced climate change to varying degrees, and without global warming the chance of the three occurring together like this would have a probability of about zero. So, let's make it simple, and just say climate change caused this storm.”

In a sampling of Americans, there are some interesting views and comments being made about climate change and its effects on the globe.

Writer Julia Hanna was amazed at Hurricane Sandy’s strength and ferocity,
“I heard about the hurricane from people posting about how the replica ship Bounty went down, and it seemed surreal to hear about a hurricane taking down a ship. I am not a climatologist, but I have never heard of a hurricane of such severity.”

Although losing ships in a hurricane is not a new phenomena, evidence is piling up that devastating hurricanes are on the rise due to global warming. In a report by the NOAA (National Oceanic and Atmospheric Administration), hurricanes are expected to become more frequent in the coming decades:
“Anthropogenic warming by the end of the 21st century will likely cause hurricanes globally to be more intense on average (by 2 to 11% according to model projections for an IPCC A1B scenario). This change would imply an even larger percentage increase in the destructive potential per storm, assuming no reduction in storm size.”

As the clean-up from Hurricane Sandy continues, more people are starting to wonder why we are having such extreme weather events around the globe. Doug Harry, West Coast resident, comments:
“Too many people dismiss climate change. You don’t make mother nature angry.”

Many that Diaz interviewed agree with Doug, that the Earth is now showing us the consequences of not tackling climate change earlier on.

Patrick McNulty, another AMEG member, has some ideas for tackling the problem that climate change is bringing us.
“Not allowing solar radiation to re-radiate back out to space because of fossil fuel GHG's trapping that energy in the atmosphere/oceans raises Earths total energy budget closer to the surface. You can now expect once in a lifetime storms to occur every decade. BTW, my tunnel idea reverses this trend.”

Patrick McNulty proposes tunnels
Patrick’s tunnel idea for dealing with the effects of Arctic ice melting are one of the many “solutions” that are being examined in the response to battling the effects of climate change.

Changing the way we consume fossil fuels is being tackled by other inventive people including an idea that includes the use of “bio-fuel”. One manufacturer of this bio-fuel cites that there would be less impact on our environment, one way to slow down human’s contribution to the problem of our warming climate.

In a opening statement on their website, the makers of the new bio-fuel Envirolene say it's:
“the world’s strongest, cleanest alcohol fuel. It’s a new, more powerful class of ”oxygenate” fuel. It’s stronger and cleaner than ethanol, more profitable to produce, and this new clean fuel powers any gas or diesel engine from a ship to a small engine with no modifications.”

Jay Toups, CEO and managing partner of BioRoot Energy, the makers of Envirolene, comments,
“There are 1 billion plus tailpipes and smokestacks spewing emissions every day. That's the real threat because it never stops.”

Mead Rose, who has also been following the climate change debate for several years, closely follows the melting of the Arctic ice and it’s ramifications.

In one of the articles that Mead submitted, the evidence of climate suppression is exposed. In an 2009 article named, “Group Promoting Climate Skepticism has Extensive Ties to Exxon-Mobil”, evidence makes it clear that there has been an ongoing battle by Big Oil companies to discredit scientific evidence about climate change.

In his blunt statement in the article, Joseph Romm, lauded climate expert and author of the blog Climate Progress, said:
“Exxon-Mobil essentially funds people to lie. It’s important for people to understand that they pay off the overwhelming majority of groups in the area of junk science.”

Joe Romm also makes the connection between Superstorm Sandy and climate change when he stated today at Climate Progress:
“Scientists worst-case scenarios are already happening - latest findings deserve attention so that Sandy doesn't become just another Cassandra whose warnings are ignored. Now climate scientists project that we risk up to 10 times as much warming this century as in the last 50 years — with many devastating consequences from dramatic sea level rise to Dust-Bowlification.”

With the battle over climate change continuing, climate skeptics and disinformation concerns climate scientists who have been trying to warn of catastrophic consequences if we don’t address it now.

One well know climate scientist, Michael Mann, a Penn State University scientist who has been studying the climate for decades, said that ocean waters were about 1 degree warmer thanks to man-made climate change, one factor that clearly caused Sandy to swell. Mann, author of “The Hockey Stick and the Climate Wars”, has been an outspoken critic on the debate over climate change.

Politicians, who used to shy away from the discussion of climate change, are even starting to “come clean” about what’s happening to our climate. With an estimated 3 foot rise in California’s sea level expected by 2100, California Governor Jerry Brown is pulling no punches in dealing with climate change deniers.

In a dire warning the California governor recently said:
Humanity is getting close to the point of no return.

EQECAT, a consultancy based in Oakland, California, estimates the economic losses from Hurricane Sandy at between $30 billion and $50 billion in economic losses, including property damage, lost business and extra living expenses.

The question is now, how much longer can we afford to debate about climate change?

Climate Change Sandy Says to US: 'Take That, Idiots!'

By Nathan Currier


Superstorm Sandy shows signature of human-induced climate change 

Nathan Currier, senior climate advisor for Public Policy Virginia

After the second presidential debate, moderator Candy Crowley said, "Climate change -- I had that question, all you climate change people. We just -- you know, again, we knew that the economy was still the main thing, so you knew you kind of wanted to go with the economy." And the media's been talking about low information voters?

Now, along comes Sandy, who says to Candy, "Okay, then, take that!" See, Sandy doesn't get into debating these things, either. Now, let's see what Sandy's bill ends up being -- anyone taking bets? -- then let's sit down and talk some economy. In fact, there's an idea: Maybe a new American pastime could be organized 'disaster gambling,' with states collecting revenue as everyone bets on the tab for each new upcoming climate change disaster in their respective states?

Perhaps some still take issue with the suggestion that a superstorm like this is caused by our human-engendered climate change. But cigarette packages say things like, "cigarettes cause fatal lung disease." This, of course, is just shorthand, a monumental simplification, because in fact causation in complex systems is always a vastly complicated affair, and tobacco companies spent lots of money blowing smoke in the face of all that complexity: but the likelihood of getting lung disease is so greatly increased by smoking that eventually they gave up and we all agreed to go 'low-info' by just saying cigarettes cause fatal lung disease. As I'll demonstrate, in much the same way, we might as well keep it simple and just say this superstorm is caused by our human-made climate change.

I've been writing on the arctic crisis, and in a recent long list of immediate physical changes from loss of summer arctic sea ice, I listed (as #12) its potential impacts on weather at lower latitudes. It so happens that it is just at this time of year that this has the clearest line of causation, since lots of heat and moisture enter the atmosphere from the open waters that had been ice covered, and latent heat is released in the refreezing process, which progresses rapidly as the arctic cools down right around now. As Jennifer Francis of Rutgers University described in a recent paper: "This warming is clearly observable during autumn in near-surface air temperature anomalies in proximity to the areas of ice loss."

And this in turn becomes very important for large-scale atmospheric circulation. For example, Dr. Francis has used the metaphor of a river going down a steep incline, which runs straight, versus a river that runs along a flat plain, which tends to meander. Likewise the jet stream, since the normal energy gradient between arctic air and that of lower latitudes has become more relaxed in tandem with ice extent drops, is tending to meander more, and hence move more slowly as well. As the Francis paper said, "Previous studies support this idea: weaker zonal-mean, upper-level wind* is associated with increased atmospheric blocking events in the northern hemisphere." [*she means high west-east moving winds]

Let's look back again at this superstorm, and you'll see that important features of what you're about to experience stem from the arctic situation I've been discussing. First, arctic air is coming down to hook up with Sandy from the dip of the jet stream. Francis writes (from personal communication),
"The huge ice loss this summer, and subsequent enhanced warming of the Arctic (see attached figure), may be playing an important role in the evolution of Sandy by enhancing the amplitude of waves in the jet stream."

At the same time, high pressure over Greenland, and the extremely negative state of the North Atlantic Oscillation, is creating a blocking event that is impacting the path of Sandy herself, sending her back west over the U.S. Again, Dr. Francis (in personal communication):
"In this case, the effects could be causing strengthening of the block, elongating the block northward, and/or increasing its duration -- and this block is what's driving Sandy on such an unusual track westward into the mid-Atlantic coast."

Now, let's add to all that the underlying and obvious thing -- that Sandy is only surviving as a hurricane so far north, almost in November, because there are record high sea surface temperatures off the U.S. East coast right now. And while the third storm component, the one coming in from the west, might seem less remarkable, that is also something that generally becomes more probable with global warming, as our atmosphere can hold more water vapor as it warms and the evaporation rate is also increased by the warming. Thus, all major components of this superstorm show the signature of human-induced climate change to varying degrees, and without global warming the chance of the three occurring together like this would have a probability of about zero. So, let's make it simple, and just say climate change caused this storm.

I'm in New York City, just as much in the path of Sandy as so many others are, but come on, you do just have to sit back and love it, appreciate the full irony of it all, with Sandy striking right at those most sensitive loins of our American democracy, threatening to interrupt our sacred electoral process, after that process blocked climate change out, and now an atmospheric blocking pattern, created by that very climate change, pushes Sandy back on us. In a time when climate silence trumps climate science, when the candidates seem terrified to mention the 'C-word,' Candy, I hope you enjoy meeting Sandy. Maybe if the election gets as messed up as 2000, you three can even find time to meet up again, and go over a little issue you couldn't quite find time to fit in before? In my next piece I'll get back back to discussing what we should do right away, and hopefully it will at least be a bit clearer that this is serious business.

Hurricane Sandy moving inland

Hurricane Sandy is moving inland and its impact is forecast to be felt as far away as in Toronto and Ottawa.

Coastal Watches/Warnings and 5-Day Track Forecast Cone
Hurricane SANDY Advisory #019       11:00 PM EDT Fri October 26, 2012
from:  National Hurricane Center (check link for updates!)



Paul Beckwith,
B.Eng, M.Sc. (Physics),
Ph.D. student (Climatology)
and Part-time Professor,
University of Ottawa
 
This prompted Paul Beckwith to make the following comments:

All storms veer to the right in the northern hemisphere due to the spinning of the earth (1 revolution per day). Except when there is a tilted high pressure region northward and it has to go left and there is a massive low pressure region left that sucks it there as well. 

Why the high pressure ridge and massive low pressure? Because the jet stream is wavier and slower, a situation that is happening more and more often, because of massive sea ice decline this summer. Which is due to Arctic amplification feedbacks. Which in turn is due to rising greenhouse gases. Which is due to humans.

The situation is further illustrated by the image below, from ClimateCentral.

An atmospheric "blocking pattern" will push Sandy north, then northwestward, into the Mid-Atlantic or Northeast. Click to enlarge the image.     Credit: Remik Ziemlinski, Climate Central.
In an earlier post, Paul Beckwith described that a very rare cyclone churned up the entire Arctic region for over a week in early August 2012, destroying 20% of the ice area by breaking it into tiny chunks, melting it, or spitting it into the Atlantic. Cold fresh surface water from melted sea ice mixed with warm salty water from a 500 metre depth! Totally unexpected. A few more cyclones with similar intensity could have eliminated the entire remaining ice cover. Thankfully that didn't happen. What did happen was Hurricane Leslie tracked northward and passed over Iceland as a large storm. It barely missed the Arctic this time. Had the storm tracked 500 to 600 kilometres westward, Leslie would have churned up the west coast of Greenland and penetrated directly into the Arctic Ocean basin.

We dodged a bullet, at least this year. This luck will surely run out. What can we do about this? How about getting our politicians to listen to climatologists, for starters.
