NASA Finds ‘Amazing’ Levels Of Arctic Methane And CO2, Asks ‘Is a Sleeping Climate Giant Stirring in the Arctic?’

By Joe Romm / Climate Progress – on Jun 13, 2013: A NASA science team has observed “amazing and potentially troubling” levels of methane and CO2 from the rapidly warming Arctic. Given the staggering amount of carbon trapped in the permafrost — and the fact that methane is a very potent heat-trapping gas — the…

Large methane emission upon spring thaw from natural wetlands in the northern permafrost region

CH4 emission upon spring thaw in the high latitudes might be enhanced by the projected climate warming Abstract The permafrost carbon–climate feedback is one of the major mechanisms in controlling the climate–ecosystem interactions in northern high latitudes. Of this feedback, methane (CH4) emission from natural wetlands is critically important due to its high warming potential.…

US Midwest – Jet Stream delivers Dangerous Flash Floods – “A Water World” (August 2013)

August 8 2013: Mangled Jet Stream Delivers Four Months Worth of Rain in One Week to Missouri; Central, Eastern US to Remain Under Severe Flood Threat ABC News last night, in the below video, aptly described the hardest-hit areas as turning into ‘a water world.’ The coverage shows storm shocked residents staring in awe at…

Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean?

Recently freshwater intake into the Arctic Circle have changed ocean currents, in the following a collection of related science, and what if freshwater currents drive warmer water into the deep ocean and unlock methane hydrates? Mechanism have been identified recently. Arctic freshwater input into the North Pacific could serve as a catalyst for methane hydrate…

Pakistan and Afghanistan monsoon floods kill dozens August 4, 2013

Eastern Afghanistan and neighbouring Pakistan have been hit by torrential rain, causing floods which have killed at least 80 people. The region has suffered devastating floods during the monsoon period for the past three years. Related Increased Methane emissions from summer Monsoon High methane in North Africa, Middle East and South Asia. The upper tropospheric…

Increased Methane emissions from summer Monsoon

Eastern Afghanistan and neighbouring Pakistan have been hit by torrential rain, causing floods which have killed at least 80 people. The region has suffered devastating floods during the monsoon period for the past three years. High methane in North Africa, Middle East and South Asia. The upper tropospheric methane continues to build.  The MODIS image…

Methane in the Arctic Circle

Methane In conditions without oxygen, such as at the bottom of a lake orthe sea, decomposition turns organic matter into methane, rather than carbon dioxide. Large increases in methane emissions would be a grave concern, because methane is 25 times moreeffective at warming the planet than carbon dioxide (over a 100 year time scale). Lakes,…
