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 […]
Greenland and Antarctica have raised global sea levels by more than half an inch in the last 16 years, according to data from the most advanced laser that the National Aeronautics and Space Administration (NASA) has ever launched into space to observe the earth. While the figures themselves are consistent with other studies, as The […]
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 […]
U.S. space agency NASA said Thursday its new mission would explore Titan, Saturn’s largest moon, using a drone lander called Dragonfly. The crewless craft with four propellers is slated to launch in 2026 and reach its destination in 2034. “What really excites me about this mission is that Titan has all the ingredients needed for […]
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 […]
Last week, NASA tweeted a photo of a perfectly natural and rectangular iceberg spotted during a flyover of the northern Antarctic Peninsula. The unusual image blew up online and now NASA is back with more photos of weirdly angular icebergs from the same Operation IceBridge trip. From yesterday's #IceBridge flight: A tabular iceberg can be […]
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 […]
