New research from McMaster University suggests the pandemic has created a paradox where mental health has become both a motivator for and a barrier to physical activity.

When winter storms threaten to make travel dangerous, people often turn to salt, spreading it liberally over highways, streets and sidewalks to melt snow and ice. 

Scientists are using weather forecasts to predict the location and scale of impending meningitis outbreaks in sub-Saharan Africa.

Respiratory disease increased markedly following one of Iceland’s largest volcanic eruptions, a new study has found.

In the vast Colorado River basin, climate change is driving extreme, interconnected events among earth-system elements such as weather and water. 

A new study shows that thick sea-ice can increase the sensitivity of Greenlandic fjords to climate warming.

Inland waters are an important component of the global carbon cycle and function as active reactors, transporting and transforming large quantities of naturally- and anthropogenically-derived carbon.

Since the early 2000s, scientists have observed that the Antarctic ice sheet is losing mass at a rate that is accelerating.

Rising global temperatures are causing frozen Arctic soil – permafrost – to thaw. In a new study, researchers have discovered something surprising: small rivers, creeks and streams that flow into larger lakes and coastal waters seem be to getting colder as permafrost melts.

Coastal communities face increasing danger from rising water and storms, but the level of risk will be more closely tied to policy decisions regarding development than the varying conditions associated with climate change, new research by Oregon State University suggests.
