Scientists leveraged a NASA supercomputer to explore possible scenarios for Earth supercontinents and climate 200 and 250 million years into the future.
New research shows that improved air quality caused by reducing emissions from burning fossil fuels and other sources could improve human health and prevent economic losses.
The study is the first to document changing atmospheric ammonia concentrations in Africa over an extended period.
Climate change may affect the production of maize (corn) and wheat as early as 2030 under a high greenhouse gas emissions scenario, according to a new NASA study.
The American West will experience increased drought conditions in the future under both high and low greenhouse gas emissions scenarios, but the most severe drought conditions can still be avoided if future emissions are limited.
The effects of human-caused global climate change are becoming more and more apparent, and these environmental changes touch every part of crop production.
As Earth's atmosphere continues to warm due to climate change, droughts are becoming more frequent, severe and pervasive. Ranchers throughout the U.S. are using data from NASA and others to care for their herds and land during drought conditions.
After the historic hurricanes Eta and Iota of 2020, NASA's Disasters program provided products updated on a near real-time basis for teams on the ground.
A new joint initiative by NASA/GISS and research partners has developed analyses of greenhouse gas emissions from the food system for use by climate modelers in projecting future changes in Earth's climate.
Scientists at NASA/GISS have voted the journal article “GISS-E2.1: Configurations and climatology” by Max Kelley et al. as the top work among 175 research publications by institute staff published in 2020.
NASA/GISS contributed results from hundreds of historical and future climate simulations to the international project that were run on the NCCS Discover supercomputer.
Initial results from a climate model intercomparison project suggest that the economic and social changes brought on by the COVID-19 pandemic won't provide any real climate benefits.
NASA has joined the National Climate Task Force, which is outlined in an executive order issued by President Joe Biden.
NASA researchers have found a small but unexpected decrease in air pollution over some parts of Africa despite growing use of fossil fuels in many countries due to development and economic growth.
A report by the U.N. Environment Programme documents how most countries have adopted climate adaptation into their policy and planning, but how well they are doing so is a mixed picture.
Globally, 2020 was the hottest year on record, effectively tying 2016, the previous record. Overall, Earth's average temperature has risen more than 2 degrees Fahrenheit since the 1880s.
The events of 2020 are consistent with what models have predicted: extreme climate events such as severe heat waves, larger wildfires and more intense hurricanes are more likely because of greenhouse gas emissions.
Impact assessments help identify and quantify risks to the world's food supply as well as evaluate sustainable adaptation and mitigation strategies.
