Extreme glacier melt and climate change

Glaciers around the world are melting faster than in any previous decade since measurements began. Glaciers form when snow accumulates over many years and compresses into ice. Glaciers accumulate snow in the winter, and then melt ice in the summer. Cold temperatures, more snow, or both,... click to read more

Global warming blamed for Earth’s largest mass extinction

The industrial burning of fossil fuels is adding greenhouse gases to the atmosphere, trapping heat near the planet's surface and warming the oceans. A major effect of warming is to reduce the amount of dissolved oxygen (O2) found in the sea. This effect arises for... click to read more

Cascading effects of a marine heatwave impact dolphin survival and reproduction

Extreme weather events such as droughts, heavy rainfalls or extreme temperature fluctuations are occurring more frequently around the globe associated with global climate change. In early 2011, the western Australian coastline was hit by an unprecedented marine heatwave, which turned the coastal waters into a... click to read more

For polar bears the cost of living is rising

A warming Arctic is causing reductions in sea ice thickness and increasing its drift speed. Compositional and dynamic changes in sea ice could have impacts on the ability of ice-dependent vertebrates to acquire and amass energy needed for maintenance, growth, and reproduction. Knowledge of how... click to read more
