A new study shows a correlation between the end of solar cycles and a switch from El Nino to La Nina conditions in the Pacific Ocean, suggesting that solar variability can drive seasonal weather variability on Earth.

Without restoration efforts in coastal Louisiana, marshes in the state could lose half of their current ability to store carbon in the soil over a period of 50 years, according to a new paper published in American Geophysical Union Journal of Geophysical Research Biogeosciences.

The ocean’s “biological pump” describes the many marine processes that work to take up carbon dioxide from the atmosphere and transport it deep into the ocean, where it can remain sequestered for centuries.

More snow is melting during winter across the West, a concerning trend that could impact everything from ski conditions to fire danger and agriculture, according to a new CU Boulder analysis of 40 years of data.

Researchers studying mercury gas in the atmosphere with the aim of reducing the pollutant worldwide have determined a vast amount of the toxic element is absorbed by plants, leading it to deposit into soils.

Washington, D.C.’s Tidal Basin, flanked by rows of the city’s celebrated cherry trees, is facing a growing threat from rising seas and land subsidence.

For decades, Europe has poured millions of tons of its trash into incinerators each year, often under the green-sounding label “waste to energy.”

Bad news for allergy sufferers: The rising temperatures over the past three decades have impacted the onset, duration and intensity of the pollen season in Switzerland.

How plants will fare as carbon dioxide levels continue to rise is a tricky problem and, researchers say, especially vexing in the tropics. Some aspects of plants’ survival may get easier, some parts will get harder, and there will be species winners and losers.

New research from the University of Kansas published in Earth-Science Reviews offers insight into one of the world’s most powerful monsoon systems: the Indian summer monsoon.
