Heat Waves to Become Much More Frequent and Severe

Science Daily Aug. 15, 2013 — Climate change is set to trigger more frequent and severe heat waves in the next 30 years regardless of the amount of carbon dioxide (CO2) we emit into the atmosphere, a new study has shown. Extreme heat waves such as those that hit the US in 2012 and Australia…

Heat stress reduces labor capacity under climate warming

NOAA study about heat stress and projected labor impact: John P. Dunne, Ronald J. Stouffer, and Jasmin G. John. Journal: Nature Climate Change. DOI: 10.1038/nclimate1827 Key Findings Due to projected increases in temperature and water vapor in the atmosphere: Labor capacity losses related to heat stress are projected to double globally by 2050 with a warming climate. Global…

Global CH4 Atmospheric Methane Average 1811ppb(METOP-2)

Continuing the global CH4 methane average jump, on August 13, 2013 am, 0-12 hr, we hit a new high average of 1811 ppb. A comment at Arctic Sea Ice Forum notes: “Assumed methane emissions for the RCP scenarios; which clearly shows that we are now exceeding the methane emissions assumed for RCP 8.5; which is…

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. http://www.nasa.gov/mission_pages/fires/main/index.html

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…
