Our Ongoing Climate System Destabilization
The Arctic region average temperature is from 6 to 8 degrees Celsius (11 to 15 F) warmer than normal. Arctic sea ice extent maximum occurred a month early. Our climate system is breaking apart in front of our eyes. Ridiculously, the term "faster than normal" is still used to describe sea ice collapse, accelerating sea level rise and every other climate system parameter. Nothing is normal with our ongoing exponentially abrupt climate change...

Fending Off Scientist's Attacks on "The Uninhabitable Earth". Part A
The controversy over the accuracy of the New York Magazine article "The Uninhabited Earth" expands and deepens. Sixteen scientists examined and commented on the article, and gave it a low rating for "scientific accuracy" on the website climatefeedback.org; normally I agree with ratings from this great website, but NOT in this case. Mainstream science does NOT have a good understanding of abrupt climate change, & "jumped-the-shark" in this case.

A little chat about methane
For about 3 years AMEG (Arctic Methane Emergency Group), to which I belong, has been doing the sandwich board, sky-is-falling routine about the enormous risk of large methane releases from the greatly warming Arctic. Support has come from prominent Russian scientists who have been leading teams of international researchers in observing the methane emissions for years, most noticeably on the ESAS (Eastern Siberian Arctic Shelf) and in Siberian permafrost. And now, it turns out that AMEG views on the risk are supported also by a 2012 paper looking at methane mitigation and risks in the Arctic from (drumroll please)...the LLNL (Lawrence Livermore National Laboratory). Yes, the US government lab that developed the A-bomb. Meanwhile, "methane-deniers" were out in full force at the recent UK Royal Society meeting, which made fun of Peter Wadham's talk, and criticized the Russian work (they were not even invited to speak, and -30 sent a scathing rebuttal to the organizers). The plot thickens...

Abrupt Cryospheric Tipping Elements in Climate System
Computer modelling simulations of climate change have a very difficult time accounting for abrupt, nonlinear state changes, also known as tipping points. Since IPCC (Intergovernmental Panel on Climate Change) reports, including the recent IPCC1.5 report rely too much on computer models, they tend to understate the urgency and emergency state of ongoing abrupt climate change. In this video I discuss the main broad-brush tipping points in the climate system, with a focus on the cryosphere (frozen regions).

Abrupt Climate Change Will Rapidly Blow Past 1.5C and 2C
As I filmed today, yet another massive hurricane has just come ashore in Florida’s panhandle. Hurricane Michael, at 155 mph (1 mph shy of Cat. 5) appeared almost out of nowhere and strengthened rapidly in the way too-warm Gulf of Mexico. This video is not just on this storm, but primarily on the human/media/global storm that has arisen with the release of the IPCC 1.5C report on our present state of the climate system, and whether or not we can keep global temperature rise to 1.5C or even to 2C.

Do Jet Streams Vanish with Arctic Sea-Ice?
What happens to the jet streams when we lose all Arctic sea ice and snow cover? Do they vanish? Do they still exist as a weak remnant farther north? Does the 3 cell atmospheric circulation reduce to 2 cells or even 1 cell? It would be nice knowing these things, before they actually happen in a few short years.

Angry Earth Causing Record CO2 Level Rise?
Feb, 2016 the atmospheric CO2 level was 404.16 ppm, or 4 ppm larger than just a year ago. Mar 25, 2016 hit 405.81 ppm, almost 5 ppm larger than only one year ago. Average levels rose a record 3.09 ppm in 2015, slightly less in 2014 and a record (then) 2.90 in 2013. Yet global emissions from humans have been reported to have levelled off the last few years. What gives? Could be BAD. Could mean Earth sinks are maxed out and/or sources are rising.

Alpine Glacier Melt-Out at the Third Pole
Since 1970 about 15% of the glacial ice has melted out at the “Third Pole”; the extensive region with high elevations in Asia that encompasses the Himalayan Mountains and the Tibetan Plateau. Warming is being amplified by a little-known feedback called Elevation Dependent Warming (EDW). A conservative estimate is that we will lose one-third, one-half or two-thirds of the ice with average global temperature change of 1.5 C, 2.0 C, and 4.0 C, respectively, threatening the water supply (and food supply) for up to 2 billion people.

Understanding Atmospheric Circulation Patterns
I teach you how (the layperson, or not) to draw the atmospheric circulation patterns of the Earth. All you need to know is that "hot air rises", there are 3 main cells, and moving objects north of the equator turn to the right (opposite in the south). With this knowledge in your "toolkit", you can better understand how the jet streams form, and how they change as the Arctic rapidly warms.

Methane Warming At Least 34x Higher than CO2
My Methane Pet Peeve. Almost all reports (blogs, articles, newspapers, mainstream or not) incorrectly state that methane is 25x, or 24x or 22x stronger for warming than carbon dioxide. WRONG. Did I say WRONG. Over 100 years, the correct number from IPCC AR5 (2013) is 34x. It is 86x over 20 years, and up to 200x over a year or two. Methane lifetime is about 11 years in the atmosphere, but varies with latitude. The risk of large methane burps, especially in the Arctic is HUGE and growing.

Arctic Methane: A Catastrophe in the Making
Up to 2005, the oceans over the shallow continental shelves in the Russian Arctic (ESAS, Laptev) were ice covered, keeping the -100 meter deep oceans near freezing temperatures. Since 2005, the ice cap cover has gone. The water has warmed as high as 17 degrees C there in summer, heating the sea-floor, perforating the permafrost cap, & thawing methane hydrates.

Bubble, Bubble. GigaTons of Methane Trouble.
Vast amounts of methane exists within ocean floor sediments on the Eastern Siberian Arctic Shelf, in the form of methane hydrates & free methane gas. Up to recently, gas release to the shallow water column (50 meters deep) & atmosphere has been slow, with the subsea permafrost acting as a million corks on a million champagne bottles to contain the methane.

Ocean Currents Disruption: Slower and Wavier
Cutting edge science finds ocean currents slowing down. We all know the equator is warm and poles are cold. This temperature difference causes heat flow from the equator to poles. As the Arctic warms like crazy, heat flow there slows, thus jet streams slow and are wavier; the same slowing and waviness increase happens with ocean currents.

Global Average Temperature Rising About 3x Faster Over Land Than Water
Last year (2018) was the 4th warmest year, following behind El Niño influenced years 2015 (3rd), 2016 (1st), and 2017 (2nd). An El Niño may develop this year (65% chance) but is not likely to be super-strong, like that in 2015 and 1998. Since 1970, average global temperatures are rising an average 0.17 degrees C per decade, but that slope is increasing. Rise over the land (0.27 C per decade) is almost 3X faster than that over the ocean (0.10 C per decade). Land at high latitudes gets a double whammy, due to polar temperature amplification.
