NASA-supported Study Confirms Importance of Southern Ocean in Absorbing Carbon Dioxide
Observations from research aircraft show that the Southern Ocean absorbs much more carbon from the atmosphere than it releases, confirming it is a very strong carbon sink and an important buffer for some of the effects of human-caused greenhouse gas… Read More ›
NASA’s Oceans Melting Greenland Mission Leaves for Its Last Field Trip
NASA’s airborne Oceans Melting Greenland (OMG) mission begins its final survey of glaciers that flow from Greenland into the ocean. OMG is completing a six-year mission that is helping to answer how fast sea level is going to rise in… Read More ›
Index Ranks Rainforests’ Vulnerability to Climate and Human Impacts
Scientists from NASA’s Jet Propulsion Laboratory in Southern California and other international research institutions have created a tropical rainforest vulnerability index. It will detect and evaluate the vulnerability of these diverse ecosystems to two main categories of threats: the warming… Read More ›
Human activities raised atmospheric concentrations of CO2 by 48%
Over the past 171 years, human activities have raised atmospheric concentrations of CO2 by 48% above pre-industrial levels found in 1850, according to Global Climate Change. This is more than what had happened naturally over a 20,000 year period (from the… Read More ›
NASA’s Webb to Study How Massive Stars’ Blasts of Radiation Influence Their Environments
An international team using NASA’s James Webb Space Telescope, which is scheduled to launch in October, will study a portion of the radiated cloud called the Orion Bar to learn more about the influence massive stars have on their environments, and even on the formation of our own solar system.
NASA’s S-MODE Takes to the Air and Sea to Study Ocean Eddies
After being delayed over a year due to the pandemic, a NASA field campaign to study the role of small-scale whirlpools and ocean currents in climate change is taking flight and taking to the seas in May 2021.
