By Stephanie Pappas 9 February 2024 (Live Science) – Scientists have discovered a key warning sign before a crucial Atlantic current collapses and plunges the Northern Hemisphere into climate chaos. The Atlantic Meridional Overturning Circulation (AMOC) carries warm water north from the Southern Hemisphere, where it releases heat and freezes. The freezing process concentrates salt […]
19 March 2024 (WMO) – A new report from the World Meteorological Organization (WMO) shows that records were once again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat. Heatwaves, floods, droughts, wildfires, and rapidly intensifying tropical cyclones […]
20 December 2023 (Ca’ Foscari University of Venice) – Traces of sunscreen agents were found at the North Pole, on the glaciers of the Svalbard archipelago. They were mainly deposited in winter, when night falls over the Arctic. A study conducted by researchers from Ca’ Foscari University of Venice and the Institute of Polar Sciences – National […]
By Kevin Krajick 7 December 2023 (Columbia Climate School) – A massive new review of ancient atmospheric carbon-dioxide levels and corresponding temperatures lays out a daunting picture of where the Earth’s climate may be headed. The study covers geologic records spanning the past 66 million years, putting present-day concentrations into context with deep time. Among […]
By Lois Parshley 20 July 2023 (The Atlantic) – Ever since some of the earliest projections of climate change were made back in the 1970s, they have been remarkably accurate at predicting the rate at which global temperatures would rise. For decades, climate change has proceeded at roughly the expected pace, says David Armstrong McKay, a […]
26 May 2023 (University of Leeds) – A study has found widespread mass loss of glaciers and ice caps in Greenland since the start of the 20th century. The research provides critical insights into long-term changes to the glaciers and ice caps as a result of climate change, which has contributed about one fifth to […]
Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]
By Seth Borenstein 5 December 2022 (AP) – Much of the Arctic is in a burst of freak December warming. In Utqiagvik, Alaska’s northernmost community formerly known as Barrow, it hit 40 degrees (4.4 degrees Celsius) Monday morning. That’s not only a record by six degrees (3.3 degrees Celsius) but it’s the warmest that region has seen […]
13 December 2022 (NOAA) – A typhoon, smoke from wildfires, and increasing rain are not what most imagine when thinking of the Arctic. Yet these are some of the climate-driven events included in NOAA’s 2022 Arctic Report Card, which provides a detailed picture of how warming is reshaping the once reliably frozen, snow-covered region which […]
By Seth Borenstein 6 November 2022 SHARM EL-SHEIKH, Egypt (AP) – Earth’s warming weather and rising seas are getting worse and doing so faster than before, the World Meteorological Organization warned Sunday in a somber note as world leaders started gathering for international climate negotiations. [Eight warmest years on record witness upsurge in climate change impacts –Des] […]
