Newly discovered Mesospheric Polar Clouds possible indicator of Global Warming

The Aeronomy of Ice in the Mesosphere (AIM) mission is the first satellite dedicated to the study of noctilucent clouds. Noctilucent clouds, sometimes called Polar Mesospheric Clouds, were first reported in 1885. Forming at altitudes above 50 miles, they are so faint that they can only be seen from the ground in the reflected light…

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…

NASA: Wildfires, Smog – Particulate Matter Will Only Get Worse (August 2013)


August 10, 2013 – NASA Research is showing due to the increase in the earth’s temperature, we can expect to see more wildfires, and fires in areas that normally don’t see fires. NASA scientists talked to The Weather Channel about the latest research.

NASA: Potential Evaporation in North America Through 2100 (August 2013 in HD)

Published on Aug 9, 2013 by NASA: This animation shows the projected increase in potential evaporation through the year 2100, relative to 1980, based on the combined results of multiple climate models. The maximum increase across North America is about 1 mm/day by 2100. This concept, potential evaporation, is a measure of drying potential or…

NASA: The Future of Fires in Perspective to Future Emissions Scenario’s (August 2013)

Published on Aug 8, 2013 by NASA: With climate change, certain areas of the United States, like the great Plains and Upper Midwest, will be at a greater risk of burning by the end of the 21st-century. Areas like the Mountain West that are prone to burning now will see even more fires than they…

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…

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…

NASA: Projected U.S. Temperature Changes by 2100

NASA: The average temperature across the continental U.S. could be 8 degrees Fahrenheit warmer by the end of the 21st century under a climate scenario in which concentrations of the greenhouse gas carbon dioxide rise to 800 parts per million. Current concentrations stand at 400 parts per million, and are rising faster than at any…

Why Global Warming Should Keep You Awake at Night: Dr. Jennifer Francis Gives Chilling Testimony to Congress

Via Robertscribbler: In a July 18 testimony to Congress, Dr. Jennifer Francis, an atmospheric scientist from Rutgers and key innovator to understanding how climate change has brought about dangerous alterations to the Northern Hemisphere Jet Stream, provides five compelling reasons why we should all be quite concerned about human caused global warming. They include: 1.…

Stable Antarctic Permafrost Melting Faster than Expected

University of Texas: July 24, 2013 AUSTIN, Texas — For the first time, scientists have documented an acceleration in the melt rate of permafrost, or ground ice, in a section of Antarctica where the ice had been considered stable. The melt rates are comparable with the Arctic, where accelerated melting of permafrost has become a…
