As the planet warms, past episodes of the natural weather phenomenon may no longer be a reliable guide of how the next one ...

Since the Industrial Revolution—an event made possible by the use of fossil fuels in everything from power plants to transportation—Earth has gotten hotter. 2024 was the hottest year on record and the ...

Strong El Niño is forming in the Pacific—expect a surge in global heat and big weather swings, with the Southern U.S. in the ...

Rising carbon dioxide (CO 2) levels are known to raise temperatures in Earth's atmosphere. But slow feedback processes, including heat storage in the ocean and changes in the carbon cycle, mean that ...

The Indian Ocean is smaller than the two other major ocean basins, but its impact on the global climate is mighty, according ...

The circumglobal teleconnection pattern (CGT) is a key mode of atmospheric variability during boreal summer, identified by an upper-tropospheric wave train propagating along the subtropical jet. CGT ...

Oceans are experiencing sudden temperature changes due to climate change, affecting marine ecosystems and global fisheries.

Schematic of CGT and its impact on heatwave. The upper-tropospheric wave train is CGT, and the anti-cyclonic (cyclonic) anomaly can lead to longer (shorter) duration of heatwave. The Circum-global ...

Real-time tools, visuals, and other resources to quantify the role of climate change in weather events. Alerts We issues alerts in many instances when the Climate Shift Index identifies a notable ...

Claims that the oceans are now driving a new phase of global cooling have surged across social media, but they collide with a large and consistent body of scientific evidence. Ocean measurements from ...
