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.

Hydrologists show environmental damage from fog reduction is observable from outer space
A new paper presents the first clear evidence that the relationship between fog levels and vegetation status is measurable using remote sensing. The discovery opens up the potential to easily and rapidly assess fog’s impact on ecological health across large land masses — as compared to painstaking ground-level observation.

How climate killed corals
New study shows multiple factors joined forces to devastate the Great Barrier Reef in 2016.

Going against the trend
Global warming has affected the entire planet’s surface, except for one particular area of the ocean, which until 2015 had bucked the trend. A research team has now unraveled what was going on.

Continued carbon dioxide emissions will impair human cognition
Rising CO2 causes more than a climate crisis—it may directly harm our ability to think.

Greenland Ice Sheet meltwater can flow in winter, too
New findings published in Geophysical Research Letters underscore need for year-round investigations of Arctic hydrology.

Shelf sediments, freshwater runoff from rivers brings more carbon, nutrients to North Pole
Freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

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.

Small climate change effects can be the most obvious
Researchers looked at how climate change has already changed temperatures and rainfall patterns worldwide to the point that they would be unfamiliar to people living at the end of the 19th century. Crucially, they then examined how these changes compared with climate fluctuations already experienced in different regions of the globe.

Major Greenland glacier collapse 90 years ago linked to climate change
Ninety years ago there were no satellites to detect changes in Greenland’s coastal glaciers, but a new study combining historical photos with evidence from ocean sediments suggests climate change was already at work in the 1930s and led to a major collapse of the one of Greenland’s largest coastal glaciers.
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.
