La Nina climate cycle has peaked: UN

The 2020-2021 La Nina phenomenon has passed its peak, the UN weather agency said Tuesday, but its impact on temperatures, rain and storm patterns is set to continue.

'Moderate to strong' La Nina this year: UN

Global temperatures boosted by climate change will still be higher than usual despite the cooling effect of a "moderate to strong" La Nina weather phenomenon, the UN said Thursday.

Climate-friendly cooling to help ease global warming

A new IIASA-led study shows that coordinated international action on energy-efficient, climate-friendly cooling could avoid as much as 600 billion tons CO2 equivalent of greenhouse gas emissions in this century.

Global cooling after nuclear war would harm ocean life

A nuclear war that cooled Earth could worsen the impact of ocean acidification on corals, clams, oysters and other marine life with shells or skeletons, according to the first study of its kind.

Global cooling

Global cooling was a conjecture during the 1970s of imminent cooling of the Earth's surface and atmosphere along with a posited commencement of glaciation. This hypothesis never had significant scientific support, but gained temporary popular attention due to a combination of press reports that did not accurately reflect the scientific understanding of ice age cycles, and a slight downward trend of temperatures from the 1940s to the early 1970s. General scientific opinion is that the Earth has not durably cooled, but undergone global warming throughout the 20th century.
