Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…

Obama: A united effort with a common purpose, should guide a united world #COP21

Leaders Event – Statements by Heads of State and Government, at the 2015 United Nations Climate Change Conference COP21. In light of the 14 warmest years on record since 2000, Obama urges bold actions. Highlighting coastal erosion, lose of farm land, flooding, or ice lose he points out that we are the first generation which…

NASA: Earth potential to absorb Emissions is out of Balance

A Breathing Planet, Off Balance NASA:  Earth’s land and ocean currently absorb about half of all carbon dioxide emissions from the burning of fossil fuels, but it’s uncertain whether the planet can keep this up in the future. NASA’s Earth science program works to improve our understanding of how carbon absorption and emission processes work…

NASA: Coolants Contribute to Ozone Depletion and are strong Greenhouse Gases

According to a new NASA study, a class of widely used chemical coolants known as hydrofluorocarbons (HFC), found in refrigerators and in home and automobile air conditioners, contributes to ozone depletion by a small but measurable amount, countering a decades-old assumption. A class of widely used chemical coolants known as hydrofluorocarbons (HFC) contributes to ozone…

Arctic Sea Ice Reaches 2015 Minimum Extent

Arctic Sea Ice Summertime Minimum Is Fourth Lowest on Record According to a NASA analysis of satellite data, the 2015 Arctic sea ice minimum extent is the fourth lowest on record since observations from space began. The analysis by NASA and the NASA-supported National Snow and Ice Data Center (NSIDC) at the University of Colorado…

NASA State of Sea Level Rise Science 2015 – 30 feet of SLR possible by 2100

The panelists for this briefing were: — Michael Freilich, director of NASA’s Earth Science Division at the agency’s headquarters in Washington — Steve Nerem,…

NASA Rising Seas: The State of the Greenland Ice Sheet (2015)

Seas around the world have risen an average of nearly 3 inches since 1992, with some locations rising more than 9 inches due to natural variation, according to the latest satellite measurements from NASA and its partners. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable rise of…

Fossil Fuel Emissions could Eliminate the Antarctic Ice sheet entirely, causing about 58 m Sea Level Rise

A new open access study in Science Advances concludes that a warming beyond the 2°C target would potentially lead to rates of sea-level rise dominated by ice loss from Antarctica, and continued CO2 emissions from fossil sources could cause additional tens of meters of sea level rise, over the next millennia and eventually ultimately eliminate the…

Ice Core Secrets Could Reveal Answers to Global Warming

At the Stable Isotope Lab in Boulder, Colo., scientists are doing a lot of the same things that those CSI folks do on TV. But instead of being “crime scene investigators,” these experts are more like “cold scene investigators.” Geoscientists like lab director Jim White work primarily with one raw material : ancient ice, in…
