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.

Climate warming promises more frequent extreme El Niño events

El Niño events cause serious shifts in weather patterns across the globe, and an important question that scientists have sought to answer is: how will climate change affect the generation of strong El Niño events? A new ...

Industrial fishing behind plummeting shark numbers

A team of researchers, led by international conservation charity ZSL (Zoological Society of London), has discovered that sharks are much rarer in habitats nearer large human populations and fish markets. The team also found ...

Ocean heatwaves devastate wildlife, worse to come

Invisible to people but deadly to marine life, ocean heatwaves have damaged ecosystems across the globe and are poised to become even more destructive, according to the first study to measure worldwide impacts with a single ...

Don't rule out severe global climate change yet

A key metric of global warming is the Earth's "equilibrium climate sensitivity" (ECS), which represents the global surface warming that will accompany a doubling of atmospheric carbon dioxide. For nearly four decades, ECS ...

Global warming—worrying lessons from the past

Fifty-six million years ago, the Earth experienced an exceptional episode of global warming. In a very short time on a geological scale, within 10 to 20,000 years, the average temperature increased by five to eight degrees, ...

2018-2022 expected to be abnormally hot years

This summer's worldwide heatwave makes 2018 a particularly hot year. And the next few years will be similar, according to a study led by Florian Sévellec, a CNRS researcher at the Laboratory for Ocean Physics and Remote ...

Stronger evidence for a weaker Atlantic overturning

The Atlantic overturning—one of Earth's most important heat transport systems, pumping warm water northward and cold water southward—is weaker today than any time before in more than 1000 years. Sea surface temperature ...
