2016 Heat Felt Around Globe

created by Sam Carana with JAXA image
Above image shows that 2016 Arctic sea ice extent has been very low, if not at record low, up to April 30, 2016. This situation doesn't appear likely to improve, due to high ocean heat causing melting from below and high air temperatures that cause melting from above and that also cause water to warm up in rivers ending up in the Arctic Ocean.

The image below shows that on April 28, 2016, sea surface off the coast of North America was as much as 12.3°C or 22.1°F warmer than in 1981-2011. The Gulf Stream will make that much of this heat will arrive in the Arctic Ocean over the next few months.


The image below compares April 30 sea surface temperature anomalies between 2015 (left panel) and 2016 (right panel), showing that the sea surface in many areas is warmer in 2016 than it was in 2015.


Next to sea surface temperatures, air temperatures are rising, as illustrated by the image on the right, showing temperatures over Alaska as high as 14.6°C or 58.4°F at 64.5°N and as high as 10.8°C or 51.4°F at 66.5°N on May 1, 2016. Such rising temperatures over land will warm up rivers that will in turn warm up the Arctic Ocean.

The Google reference map below shows a large part of the Arctic Ocean, including Alaska on the left and the Beaufort Sea at the bottom. The map has an added red square inset that indicates the outlines of the map further below, which zooms in further on the Beaufort Sea.


The April 26, 2016, NASA map below shows that, while it is in places still relatively thick, the sea ice in the Beaufort Sea is strongly fractured with much water showing up in the fractures, and even more water along the coast.


Worryingly, high methane peaks have been recorded recently, as high as 2810 ppb on April 29, 2016, as illustrated by the image below, showing a large area with high methane levels east of Greenland.


Meanwhile, the heatwave in South-East Asia continues, with temperatures as high as 49°C or 120.1°F recorded on April 27, 2016, as illustrated by the image on the right.

As the image below shows, temperatures do not appear to be coming down, with temperatures as high as 49.4°C or 120.8°F forecast to hit India on May 2, 2016 (at the location marked by the green circle).

As global warming continues, this will make humidity levels rise. A 3°C warming will cause about 25% increase in absolute humidity, which will make it feel at least 6°C hotter. Moreover, water vapor is a potent greenhouse gas, further accelerating global warming.


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

  1. Hello Sam
    Hope you're doing good.
    I tripped over this a few days ago : NCAR: Global Temperature Increase To Lower Oxygen Content of Most Ocean Zones by the 2030s
    from Bobert Scribblers blog https://robertscribbler.com/2016/04/28/ncar-global-temperature-increase-depletes-oxygen-in-most-ocean-zones-by-the-2030s/
    I wrote a little word on this on my blog. It's really freaky.
    That's extinctions biggest gun so to speak.
    This planet really belongs to the microbes as I read or heard a little while ago.
    I wrote 2 articles on what's going on with life in the oceans in the last few months ; it's much worse for the marine creatures than it is for us. We keep seeing reports of thousands of dead creatures washed up on shores, even mammals and sea birds die in large numbers.
    I hope the world wakes up to at least understand that global warming is killing us all, humans, plants n trees and animals alike.
    Take care my friend and keep fighting.
    Jack
