2021 Tied for 6th Warmest Year in Continued Trend, NASA Analysis Shows

Earth’s global average surface temperature in 2021 tied with 2018 as the sixth-warmest on record, according to independent analyses done by NASA and the National Oceanic and Atmospheric Administration (NOAA). Continuing the planet’s long-term warming trend, global temperatures in 2021 were 1.5 degrees Fahrenheit (0.85 degrees Celsius) above the average for NASA’s baseline period, according

NASA-NOAA Tech Will Aid Marine Oil Spill Response

NASA and National Oceanic and Atmospheric Administration (NOAA) scientists are teaming up to test remote-sensing technology for use in oil-spill response.  Just off the coast of Santa Barbara, Calif., thousands of gallons of oil seep through cracks in the seafloor and rise to the surface each day. But this isn’t a disaster zone: It’s one

Novel Source of the Strong Greenhouse Gas Nitrous Oxide Found in Siberian Permafrost

A previously unknown source of the strong greenhouse gas nitrous oxide has been found in East Siberian Yedoma permafrost. Published in Nature Communications, the observation was made by an international group of researchers, with the lead of researchers from the University of Eastern Finland. Nitrous oxide (N2O) is the third-most important greenhouse gas after carbon

One Year From Launch: U.S.-European Satellite to Track World’s Water

An international team of engineers and technicians has finished assembling a next-generation satellite that will make the first global survey of Earth’s surface water and study fine-scale ocean currents. The Surface Water and Ocean Topography (SWOT) mission is just a year out from launch, and the final set of tests on the spacecraft have started.

NASA Study Traces Decade of Ammonia Air Pollution in Africa

A new NASA-led study is the first to document changing atmospheric ammonia (NH3) concentrations in Africa over an extended period. Ammonia is an air pollutant that can lead to heart- and lung-related illness. When present in excess in an ecosystem, it can make soil more acidic and hinder plant growth. Ammonia is emitted naturally from

ESA and NASA Launch Revolutionary Open-Source Platform

On Oct. 29, 2021, ESA and NASA publicly released the first globally harmonzed assessment of aboveground biomass—information that’s vital for managing global climate change. The Multi-Mission Algorithm and Analysis Platform (MAAP) provides seamless access to aboveground biomass information from both NASA and ESA Earth observation data. The revolutionary open-science tool is now fully operational and

NASA Releases Climate Action Plan

NASA released a climate action plan Oct. 7, 2021, aimed at averting mission impacts due to climate change, ensuring the resiliency of facilities and assets, and providing the nation and world unique climate observations, analysis, and modeling through scientific research. The plan is part of President Biden’s whole-of-government approach to confronting the climate crisis. Federal

What’s Behind California’s Surge of Large Fires?

If it seems like enormous wildfires have been constantly raging in California in recent summers, it’s because they have. Eight of the state’s 10 largest fires on record—and 12 of the top 20—have happened within the last five years, according to the California Department of Forestry and Fire Protection (Cal Fire). Together, those 12 fires

World’s Largest Open Dataset for the Development of Self-Driving Vehicles Launched

Self-driving vehicles such as cars, ships and drones offer the potential for reduced costs, lower environmental impacts and fewer accidents. Now, a new open dataset from researchers at Chalmers University of Technology, Sweden, sets a new standard for evaluating the algorithms of such vehicles, and the development of autonomous transport systems on roads, water and

Climate Change Pushes Fires to Higher Ground

Scientists have known for decades that climate change makes wildfires more common, larger and more intense. Now an international team of scientists has demonstrated a new connection between fires and global warming. Using data from Landsat satellites, they discovered that wildfires in the western United States have been spreading to higher elevations due to warmer
