The Climate Change Indicators site was not updated during Donald Trump’s presidency.

One way to investigate the record-setting deaths of the marine mammals is to perform autopsies on them, but researchers are also taking a close look at living whales for clues to what could be killing them.

Environmental engineer Gil Bohrer discusses how long-term, large-scale tracking data can shed light on the unexpected ways animals are responding to changes in the Arctic.

Knock-on effects of melting sea ice in the Arctic may be to blame for a spate of gray whale deaths along their migration route from Mexico to Alaska.

For the past two years, the charismatic marine mammals have washed up on Pacific shores in record numbers. Scientists investigating the strandings suspect warming waters and melting sea ice are partly to blame.

Marine ecologist Jeroen Ingels discusses what is known about ice shelf loss at the southern pole and how those changes are affecting local ecosystems.

Satellite images of penguin poop reveal eight entirely new colonies and confirm the existence of another three first reported in the 1960s.

The possibly record-breaking temps follow the warmest winter on record in the region.

The highest reading, taken from Seymour Island, has yet to be confirmed by the World Meteorological Organization.

The rate of population decline is outpacing the ability of the bees to find a new habitat.

The movements of water within the ocean basins has been increasing in speed over the last 20 years, a new study shows, conflicting with prior models of climate change.

Chlorofluorocarbons and other substances were banned in 1989 under the Montreal Protocol.

Biological production of this greenhouse gas, once thought to be the reserve of anaerobic microbes, occurs in these widespread, photosynthesizing cyanobacteria.

The animals have a smaller body mass, shorter legs, and longer wings than they did four decades ago.

From 1969 to 1988, 25,000 infants were born early each year as a result of hot weather, and with global warming pushing temperatures higher, more babies will be at risk for early birth.

Carbon dioxide and temperature need to increase in a constant ratio for plants to keep up with climate change.

Warming temperatures threaten reindeer herding and the preservation of cultural artifacts in Mongolia.

Insulating tundra soil with snow increased the abundance of microbial species involved in carbon dioxide and methane release.

The majority of lakes studied experienced increased bloom intensity over the past few decades.
