Vulnerable carbon stores twice as high where permafrost subsidence is factored in, new research finds
Sinking terrain caused by the loss of ice and soil mass in permafrost is causing deeper thaw than previously thought and making vulnerable twice as much carbon as estimates that don’t account for this shifting ground.

South Asia faces increased double-threat of extreme heat, extreme pollution
Extreme heat occurrences worldwide have increased in recent decades, and at the same time, many cities are facing severe air pollution problems, featuring episodes of high particulate matter pollution. This study provides an integrated assessment of human exposure to rare days of both extreme heat and high PM levels.
Continued carbon dioxide emissions will impair human cognition
Rising CO2 causes more than a climate crisis—it may directly harm our ability to think.

Flooding Stunted 2019 Cropland Growing Season, Resulting in More Atmospheric CO2
A new study determines the impact of the severe 2019 floods, and offers scientists a new tool for measuring regional-scale carbon dioxide absorption by plants.

Size of thunderstorm dome clouds may predict tornado intensity
The size of a bulge at the top of a thunderstorm’s anvil-shaped cloud may allow researchers to forecast the strength of tornadoes that spawn from such storms, according to a new study in AGU’s journal Geophysical Research Letters.

Scientists identify weather event behind extreme cold in Europe and Asia during February 2018
In the new study, researchers tested their hypothesis that a chain of events in the troposphere caused the sudden stratospheric warming and subsequent splitting of the polar vortex.

Ship emissions responsible for thousands of premature deaths in China’s Pearl River Delta
Ship emissions caused more than 1,200 ozone-related and 2,500 particulate-related premature deaths in the Pearl River Delta region in 2015, according to new research in the AGU journal GeoHealth. The new study also predicts that implementing new coastal emission controls could reduce mortality due to fine particulates by 30 percent and ozone by 10 percent by 2030.
Climate change is altering winter precipitation across the Northern Hemisphere
A team of scientists has successfully teased out the influence of human-caused climate change on wintertime precipitation over much of the last century, showing that the warming climate is significantly altering wintertime rainfall and snowfall across the Northern Hemisphere.

How the Pacific Ocean influences long-term drought in the Southwestern U.S.
New research explores what conditions in the ocean and in the atmosphere prolong droughts in the Southwestern U.S. The answer is complex, according to a study published Aug. 6 in the Journal of Geophysical Research: Atmospheres, a journal of the American Geophysical Union.

Study finds increased moisture facilitated decline in African fires in Africa
The amount of area burned across Africa declined by 18.5 percent between 2002 and 2016, according to a new study.
GeoSpace is a blog on Earth and space science, managed by AGU’s Public Information staff. The blog features posts by AGU writers and guest contributors on all sorts of relevant science topics, but with a focus on new research and geo and space sciences-related stories that are currently in the news.
