New Research More than Doubles Rate of Abrupt Thawing of Arctic Permafrost Beneath Thermokarst Lakes

The warming climate may cause the release of a massive, unanticipated burst of methane and carbon dioxide long-locked up in permafrost beneath Arctic lakes by the middle of this century, according to a new study from NASA. Permafrost has been thawing more rapidly as a result of the warming climate and mean annual temperatures have been rising more rapidly in…

Human Fingerprint Evident in Below Trend Freshwater Availability

The trend in freshwater availability in mid-latitudes worldwide appears below trend due in large part to climate change and unsustainable groundwater depletion, according to a first-of-its-kind study.

2000-Year High in Annual CO2 Emissions Set During 2015-2016 El Nino

Drought and high temperatures compromised the health of tropical rain forests across South America, Africa and the Asia-Pacific during the 2015/2016 El Nino, leading to a spike in carbon dioxide emissions, according to an analysis of data from the NASA’s Orbiting Carbon Observatory.

Europe Launches Fourth Earth Monitoring Satellite as US Congress Readies Axe for NASA Earth Science Research

The European Space Agency launched the fourth Copernicus-Sentinel Earth systems monitoring satellite this past week. Europe’s ongoing investments in space-based earth systems monitoring comes as a plan to axe NASA earth science/climate research budget makes its way to President Trump’s desk.

Latest Projections of Regional Sea Level Rise Emphasize Need for Ongoing Research, Adaptation Planning

Sea level rise along all U.S. coasts barring Alaska is projected to be higher than the global average in the three worst-case scenarios — 0.3-1 meter or more come 2100 — according to the latest projections from a public-private climate research partnership led by NOAA

An early conceptual drawing of NASA Space Solar Power

NASA and a Solar Revolution

It’s no secret that the Earth is in dire need of clean energy alternatives to fossil fuels. The source of that clean energy, however, doesn’t necessarily have to be on Earth. The Space Solar Power Initiative (SSPI) is a team of scientists from Caltech that includes researchers from NASA’s jet propulsion laboratory. These scientists propose building the largest-ever space structure…

New Approaches Needed as Blazing Hot, Dry Conditions Lead to Longer, More Intense Wildfires

High temperatures and lack of precipitation have brought an early onset to the wildfire season, highlighting a continuing trend that requires improving the way we manage landscapes to enhance their resilience, according to the U.S. Interior Dept.
