Arctic sea ice is shrinking as the world continues to warm, and a new study led by researchers at Penn State may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.

Massive volcanic events in Earth’s history that released large amounts of carbon into the atmosphere frequently correlate with periods of severe environmental change and mass extinctions.

Past climate change (often caused by natural changes in greenhouse gases due to volcanic activity) has been responsible for countless species’ extinctions during the history of life on Earth. 

Beset by severe heat throughout the Australian summer, the Great Barrier Reef is undergoing its fifth mass bleaching in eight years.

More than ever before, there is a growing interest in dedicating resources to stop the loss of biodiversity, as recently exemplified by the Kunming-Montreal Global Biodiversity Framework (GBF) decided at COP15 in December 2022.

Glacier-fed streams are undergoing a process of profound change, according to EPFL scientists in a paper appearing in Nature Geoscience. 

Tropical herbivores are on the move and that could spell trouble for subtropical seagrass meadows.

Ever-worsening floods are killing trees at an increasing rate along the upper Mississippi River, and invasive grasses are taking over. 

Getting climate models to mimic real-time observations when it comes to warming is critical – small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. 

Will ice floating in the Arctic Ocean move faster or slower over the coming decades?
