Cracks in Arctic sea ice turn low clouds on and off

The prevailing view has been that more leads are associated with more low-level clouds during winter. But University of Utah atmospheric scientists noticed something strange in their study of these leads: when lead occurrence ...

Seasonal forecasts challenged by Pacific Ocean warming

CSIRO research has found global warming will make it more difficult to predict multi-year global climate variations, a consequence of changes to long-term climate variability patterns in the Pacific Ocean.

Switching on the Atlantic heat pump

34 million years ago, the warm greenhouse climate of the dinosaur age ended, and the colder icehouse climate of today commenced. Antarctica glaciated first, and geological data imply that the Atlantic meridional overturning ...

New study: Ocean temperature 'surprises' becoming more common

August 5, 2019—A new study published this week shows how marine ecosystems around the world are experiencing unusually high ocean temperatures more frequently than researchers previously expected. These warming events, ...

Correcting historic sea surface temperature measurements

Something odd happened in the oceans in the early 20th century. The North Atlantic and Northeast Pacific appeared to warm twice as much as the global average while the Northwest Pacific cooled over several decades.

The far-future ocean: Warm yet oxygen-rich

The oceans are losing oxygen. Numerous studies based on direct measurements in recent years have shown this. Since water can dissolve less gas as temperatures rise, these results were not surprising. In addition to global ...

North Atlantic warming hole impacts jet stream

The North Atlantic warming hole (NAWH), a region of reduced warming located in the North Atlantic Ocean, significantly affects the North Atlantic jet stream in climate simulations of the future, according to a team of researchers.
