Global warming: Environmental movement resumes protests – The Irish Times

More than 3,500 global protests led by young people including Swedish activist Greta Thunberg took place in 150 countries across the world on Friday to demand scaled-up action to tackle a worsening climate crisis. It was biggest day of international…

Coldest Northern Hemisphere temperature, first recorded by UW, officially confirmed

(University of Wisconsin-Madison) Nearly 30 years after recording a temperature of minus 93.2 degrees Fahrenheit (minus 69.6 Celsius) in Greenland, the measurement has been verified by the World Meteorological Organization as the coldest recorded temperature in the Northern Hemisphere. The measurement was first recorded by a University of Wisconsin-Madison Antarctic Meteorological Research Center Automatic Weather Station in December 1991.

Island-building in Southeast Asia created Earth’s northern ice sheets

Tectonic processes are thought to have triggered past ice ages, but how? A new analysis of mountain building in the maritime tropics of Southeast Asia attributes the last ice age, which reached a maximum 15,000 years ago, to increasing rock weathering in the rising island arc from Sumatra to New Guinea over the past 15 million years, with the first ice sheets in the Northern Hemisphere appearing about 3 million years ago.

New model — Antarctic ice loss expected to affect future climate change

In a new climate modeling study that looked at the impacts of accelerated ice melt from the Antarctic Ice Sheet (AIS) on future climate, a team of climate scientists reports that future ice-sheet melt is expected to have significant effects on global climate.

Global warming may lead to practically irreversible Antarctic melting – Science News

How is melting a continent-sized ice sheet like stirring milk into coffee? Both are, for all practical purposes, irreversible. In a new study published in the Sept. 24 Nature, researchers outline a series of temperature-related tipping points for the Antarctic Ice Sheet….

Stability check on Antarctica reveals high risk for long-term sea-level rise

The warmer it gets, the faster Antarctica loses ice – and much of it will then be gone forever. That’s what a team of researchers has found out in their new study on how much warming the Antarctic Ice Sheet can survive.
