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.

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.

Forces from Earth’s spin may spark earthquakes and volcanic eruptions at Mount Etna
A new study suggests that polar motion and subsequent shifts in Earth’s crust may increase volcanic activity. “I find it quite exciting to know that while climate drives Earth’s spin, its rotation can also drive volcanoes and seismicity,” said Sébastien Lambert, a geophysicist at Paris Observatory in France and lead author of the study. The new findings, however, don’t allow scientists to forecast volcanic activity.

One of Europe’s worst famines likely caused by devastating floods
Europe’s Great Famine of 1315–1317 is considered one of the worst population collapses in the continent’s history. Historical records tell of unrelenting rain accompanied by mass crop failure…Now, new research using tree ring records confirms the historical data, showing the years of the Great Famine were some of Europe’s wettest.

Can Arctic ‘ice management’ combat climate change?
Both sea ice retreat and global warming could be slowed by millions of wind-powered pumps, drifting in the sea ice, to promote ice formation during the Arctic winter. Researchers have now, for the first time, tested the concept using a complex climate model.
