Study measures the effect of regional change in clouds caused by ships’ emissions; masking GHG warming

Green Car Congress

This puffy line is not just exhaust from the engine, but a change in the clouds that’s caused by small airborne particles of pollution. New research led by the University of Washington (UW) is the first to measure this phenomenon’s effect over years and at a regional scale. Michael Diamond/University of Washington. C, or 1.8 ?F,

Study using extreme value theory finds lack of uniform trends but increasing spatial variability in rainfall extremes in India

Green Car Congress

These findings, published in Nature Climate Change , are contrary to results of some earlier work on this subject. This is especially the case if the goal is to understand climate and rainfall variability at local to regional scales. —Ghosh et al. Shih-Chieh Kao.

Studying Climate Change with an Ice Radar Drone

Cars That Think

These great masses store enough water to raise global sea level by 65 meters should they melt entirely. Although neither ice sheet is expected to melt completely anytime soon, their incredible scale makes even small changes consequential for the future of our planet. Thomas Teisberg, an electrical engineering Ph.D.

Study Finds East Siberian Arctic Shelf Showing Instability and Widespread Venting of the GHG Methane; Releases May Be Much Larger and Faster Than Anticipated

Green Car Congress

A section of the East Siberian Arctic Shelf (ESAS) seafloor that holds vast stores of frozen methane (CH 4 ) is showing signs of instability and widespread venting of the gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov.

New NASA Satellite Survey Reveals Dramatic Arctic Sea Ice Thinning

Green Car Congress

Scientists from NASA and the University of Washington in Seattle conducted the most comprehensive survey to date using observations from NASA’s Ice, Cloud and land Elevation Satellite ( ICESat ) to make the first basin-wide estimate of the thickness and volume of the Arctic Ocean’s ice cover.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

This would increase the annual carbon emission to somewhere between 380 and 920 Mt CO 2 e by 2020 depending on water management practices and the extent of plantations. Despite increasing awareness of climate change in that period, the rate of peat destruction was higher in this last 3 year period than ever before.
