Volcanic eruptions bring images of lava and ash, not water. A new NASA study has shown that to correctly model the climate effects of an eruption scientists need to include the atmospheric effects of erupted water vapor.
July 2016 was the warmest July in 136 years of modern record-keeping according to a monthly analysis of global temperatures by scientists at NASA GISS.
Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history.
In the summer of 2016, extreme heat waves gripped Siberia, the Middle East, and North America.
An especially dry period from July to October in Indonesia, a result of the 2015-16 El Niño, contributed to a severe fire season and significant carbon and pollution emissions.
Two key climate change indicators — global surface temperatures and Arctic sea ice extent — have broken numerous records through the first half of 2016.
Interaction of dry air off the Namibian desert with moist air over the ocean forms clouds that rise and fall due to gravity, forming wave patterns.
Scientists at NASA/GISS have voted the article “The frequency and duration of U.S. hurricane droughts” by Timothy Hall & Kelly Hereid as the top work among over 170 research publications by institute staff published in 2015.
Peatlands store up to one-third of Earth's soil carbon and are sensitive to changes in climate. Studying peatland sediments offers understanding of past and future response to climate change.
New study shows that emissions from farms outweigh all other human sources of fine-particulate air pollution in much of the United States, Europe, Russia and China.
In early May 2016, a destructive wildfire burned through Canada’s Fort McMurray in the Northern Alberta region. Windy, dry, and unseasonably hot conditions all set the stage for the fire.
A new NASA analysis of 30 years of satellite data suggests that a previously observed trend of high altitude clouds in the mid-latitudes shifting toward the poles is caused primarily by the expansion of the tropics.
Elevated carbon dioxide concentrations in the atmosphere may increase water-use efficiency in crops and considerably mitigate yield losses due to climate change, according to a new NASA study.
In a study of wine grape harvests from 1600 to 2007, scientists at NASA and Harvard University found that climate change is diminishing an important link between droughts and grape harvest dates in France and Switzerland.
Almost all land surfaces on the planet experienced unusually warm temperatures during the month of February 2016, making it the warmest February in 136 years of modern temperature records.
Study finds that the drought that began in 1998 in the eastern Mediterranean Levant region — comprising Cyprus, Israel, Jordan, Lebanon, Palestine, Syria, and Turkey — is likely the worst drought of the past nine centuries.
The inability of global climate models to match the timing or placement of short-term or regional precipation patterns such as the West African monsoon may be alleviated by "downscaling" to use smaller scale climate models with increased area resolution.
