New research provides clear evidence of a human “fingerprint” on climate change and shows that specific signals from human activities have altered the temperature structure of Earth’s atmosphere.

In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better.

The Catalonia region of Spain is experiencing a long-term drought, which has shrunk reservoirs and led to water restrictions.

The need to limit flood risk in Canada is urgent, with approximately 1.5 million homes, representing 10 per cent of the Canadian residential housing market, in high-risk zones where they are ineligible for flood insurance.

As the Arctic warms and loses sea ice, trans-Arctic shipping has increased, reducing travel time and costs for international trade.

Lutz Grossmann is on a scientific mission to create tasty, animal-free protein that has a low carbon footprint and is produced without relying on agricultural land – a usual and progressively stressed source of the global food supply.

In parts of California’s iconic mountainous coasts, breathtaking beauty is punctuated by brusque signs warning spectators to stay back from unstable cliffs.

Tropical rainforests store 25%-40% of global soil carbon, though they occupy only 7% of Earth’s land area. By functioning as a carbon sink, tropical forests prevent more severe effects from climate change.

Ponderosa pine forests in the Sierra Nevada that were wiped out by western pine beetles during the 2012-2015 megadrought won’t recover to pre-drought densities, reducing an important storehouse for atmospheric carbon.

About 40 percent of interior Alaska is underlain by ice-rich permafrost – permanently frozen grounds made up of soil, gravel and sand – bound together by ice.
