by Andrew Glikson “The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum.” Noam Chomsky (1998). The level of atmospheric methane, a poisonous gas considered responsible for major mass extinction events in the past , has nearly tripled during the 20-21st centuries, from ~722 ppb (parts per billion) to above ~1866 ppb , currently reinforced by coal seam gas (CSG) emissions. As the concentration of atmospheric methane from thawing Arctic permafrost , from Arctic sediments and from marshlands worldwide is rising, the hydrocarbon industry, subsidized by governments, is progressively enhancing global warming by extracting coal seam gas in defiance of every international agreement. Methane (CH₄), a powerful greenhouse gas ~80 times the radiative power of carbon dioxide (CO₂) when fresh, sourced in from anaerobic decomposition in wetlands, rice fields, emission from animals, fermentation, a

Sea surface temperatures on the Northern Hemisphere have been rising dramatically over the years, as illustrated by above image, indicating that the latent heat tipping point is getting crossed, while the methane hydrates tipping point could get crossed soon, depending on developments. At the moment, the surface temperature of most of the Arctic ocean's is still below 0°C. Heat is entering the Arctic Ocean from the south, as illustrated by the image on the right. Hot, salty water is entering the Arctic Ocean from the Atlantic Ocean as currents dive underneath the ice, causing the ice to melt from below.  [ click on images to enlarge ] The image on the right, from the NSIDC article A step in our Spring , compares sea ice age between March 12 to 18 for the years 1985 (a) and 2021 (b). The bottom graph (c) shows a time series from 1985 to 2021 of percent ice coverage of the Arctic Ocean domain. The Arctic Ocean domain is depicted in the inset map with purple shading.

by Malcolm Light The greatest threat to humanity on Earth is the escalating Arctic atmospheric methane buildup, caused by the destabilization of subsea methane hydrates. This subsea Arctic methane hydrate destabilization will go out of control in 2024 and lead to a catastrophic heatwave by 2026. While the source region for this subsea methane is in Russian waters, the hot ocean current setting them off is the northern extension of the Gulf Stream - North Atlantic Drift, the “Svalbard Current”, which makes United States and Canadian atmospheric pollution guilty of this looming catastrophic Global Extinction event.
