The Arctic is rapidly losing sea ice, and less ice means more open water, and more open water means more gas and aerosol emissions from the ocean into the air, warming the atmosphere and making it cloudier.

A £5m project funded by the Natural Environment Research Council (NERC) to investigate the complex changes seen in sea ice around the Antarctic begins this month (March 2022) as the sea ice extent around the continent drops to a record low level.

In the Southern Hemisphere, the ice cover around Antarctica gradually expands from March to October each year.

A third of bird species in Chicago are laying their eggs a month earlier than they did 100 years ago, according to a new study that compares recent observations with data from century-old eggs.

As the population grew, the conversion of natural landscapes into farmland has become common in parts of the continent.

Organic aerosols (OAs), an important and abundant fraction of the arctic aerosol mass, plays an important role in modulating the radiative balance of the Arctic atmosphere.

The people, economy, and ecosystems of the Pacific coast states of California, Oregon and Washington are highly dependent on cool-season atmospheric rivers for their annual water supply.

The consequences of climate change are becoming increasingly frequent and alarming, especially in regions like the Mediterranean. 

The Great Barrier Reef is undergoing its sixth mass bleaching event, as unusually warm waters stress corals, authorities say. 

A University of Miami research facility in Barbados is the source of one of the largest aerosol filter archives in the world and provides vital insight into the transport of Saharan dust particles across the Atlantic.
