Barnacle geese have developed new migration routes and breeding grounds amid warming global temperatures. 

Animal species are evolving to adjust to climate change, but scientists say time is running out

The Big Fix

Scientists have been studying changes in animal physiology and behavior, some of which they believe are linked to rising global temperatures. They say the adaptations are beneficial, but may have limitations in the long term.

Sea ice plays a crucial role in cooling the planet. It’s melting at record-breaking rates.

Climate Change

According to research at the Norwegian Polar Institute, last decade’s average Arctic sea-ice levels hit their lowest in 1,000 years. And last month, sea ice reached its lowest point ever recorded in July.

A new study says if global warming continues at its current rate, more than 80% of Emperor penguin colonies will be gone in the next 80 years. Phil Trathan, who co-authored the study, joined The World’s host Marco Werman to discuss the plight of penguins.

The Big Fix

Digital tools like SIKU facilitate real-time monitoring and data gathering to give Arctic communities more capacity to track trends in sea ice and wildlife — and plan for the future.

Information collected from orbiting satellites can tell us a lot about the weather, our changing climate and abundant life on Earth. Thanks to advances in technology, soon we may be able to watch, in real-time, the movements and migration of tiny winged species, including insects.

A heat wave in Siberia signals dangerous Arctic warming

Siberia hit a record-high temperature of 100.4 degrees Fahrenheit on June 20 in the town of Verkhoyansk, north of the Arctic Circle. Scientists say it is an ominous sign of things to come. “I was shocked at the magnitude of it …” says Susan Natali, Arctic program director at Woods Hole Research Center.
