What countries emit the most net carbon dioxide? Up until now, this question has been answered by calculating the emissions of each sector in a nation’s economy via a “bottom up” approach. However, a new paper published in Earth System Science Data March 7 pilots a “top down” approach by using NASA satellite data to […]
Three astronauts landed back on Earth from the International Space Station (ISS) on Friday. A Soyuz MS-15 spacecraft undocked from the ISS at about 10 p.m. UTC Thursday, with Russian cosmonaut Oleg Skripochka and NASA astronauts Andrew Morgan and Jessica Meir on board. The Soyuz crew ship carrying the Exp 62 trio has fired its […]
By Julia Conley NASA scientists confirmed in a report Wednesday that 2018 was one of the hottest years on record, continuing what the New York Times called “an unmistakable warming trend.” Last year was the fourth-warmest on record since scientists began recording such data 140 years ago, according to NASA’s Goddard Institute for Space Studies […]
After a summer of record-breaking heatwaves and devastating wildfires, 2018 is shaping up to be one of the planet’s hottest years in recorded history. From January through September, the average global temperature was 1.39°F above the 20th century average of 57.5°F, making it the fourth warmest year-to-date on record, and only 0.43°F lower than the […]
NASA will soon activate the “most advanced laser instrument of its kind” to study Earth’s changing polar ice. The incredibly precise Advanced Topographic Laser Altimeter System (ATLAS) is the main feature of the Ice, Cloud and land Elevation Satellite-2 (ICESat-2) that successfully launched into space from the Vandenberg Air Force Base in California on Sept. […]
Climate science marks a troubling anniversary this week: in June of 1988, NASA scientist James Hansen told Congress that global warming had already begun to affect the world and would only get worse. A sweeping AP analysis finds that in the decades since Hansen’s testimony, global temperatures have risen nearly 1 degree F, while the […]
By Julia Conley With a first-of-its-kind satellite study, NASA scientists have identified more than 30 parts of the globe where the depletion of freshwater has been most dramatic, largely due to human activity and the climate crisis. Parts of India, the Middle East, Australia, the Arctic, Antarctica, and California were among the places pointed out […]
By Jessica Corbett As the Trump administration charges forward with its war on science by canceling a “crucial” carbon monitoring system at NASA, scientists and climate experts are sounding alarms over atmospheric concentrations of carbon dioxide (CO2) that just surpassed a “troubling” threshold for the first time in human history. “The reading from the Mauna […]
By Alex Kirby The Gulf Stream is slowing, the North Atlantic is cooling. An international scientific study has found new and harder evidence that one of the planet’s key heat pumps, the currents which exchange warmth between the tropics and the Arctic, are weaker today than at any time in the last thousand years. The […]
