"Atmospheric greenhouse gases have steadily increased over the last 10 years."

A global team of scientists reports that Earth’s oceans absorbed more heat in 2025 than in any year since modern observations began. The findings, published today (January 9) in Advances in Atmospheric Sciences, show that ocean heat content reached an unprecedented level, continuing a long-term warming trend.

The last three years were Earth's hottest on record, as humanity's carbon emissions continue to heat the planet.

Climate scientists are warning that global warming could trigger a cascade of "tipping points" that threaten to plunge our planet into chaos. But what exactly are tipping points, what happens if we cross them, and how can we avoid them? Tipping points are ...

A Pew Research poll shows partisan split over U.S. scientific leadership, with Democrats far more concerned about losing ground than Republicans.

This week saw the hottest global temperature ever recorded, according to data from the US National Centers for Environmental Prediction. On Monday, the average global temperature reached 17.01 degrees Celsius (62.62 Fahrenheit), the highest since records ...

Earth logged its third-hottest year on record in 2025, figures released on Wednesday showed, extending an unprecedented run of global heat and pushing the planet closer to a key warming limit.

These changes included a dramatic increase in atmospheric carbon dioxide, ocean acidification, global warming, and a decrease in oxygen levels in the oceans. Consequences: The Permian-Triassic extinction drastically altered Earth’s ecosystems, paving the way for the rise of dinosaurs in the subsequent Triassic period.
