Faster than forecast, climate impacts trigger tipping points in the Earth system

By Abrupt changes, Climate Catastrophes, climate emergency, Earth systems, Emissions flip, evolutionary boundaries, feedback, Impacts, Point of No Return, Scenarios, The Unexpected, Tipping

Permafrost collapse, Glenn Highway, Alaska. Though permafrost has been thawing slightly since the end of the Little Ice Age, the rate of thaw today is so great that in combination with Amazon collapse and collapse of Canadian forests, natural feedback emissions rival all of transportation globally. Faster than forecast, climate impacts trigger tipping points in…

Risky Feedbacks – Not In Models; Understated Solutions

By Abrupt changes, Arctic Sea Ice, Arctic warming, Climate Catastrophes, climate emergency, Climate Policy, climate restoration, climate solutions, Earth systems, Extreme Weather, feedback, Impacts, Scenarios, Solutions, Tipping

Risky Feedbacks – Not In Models; Understated Solutions Feedbacks are best understood by example. Austin’s 2023 ice storm that caused massive tree damage and excessive power outages was caused by a feedback. The ice storm stalled in a classic climate change-caused effect, creating a longer ice accumulation time than in our old climate. This additional…

Glacier Retreat, the Little Ice Age and Climate Change

By Glaciers, Impacts, in-depth and Popular Press, The Unexpected, Truthout.org
Cover Description: The Kennicott Glacier, Wrangle St. Elias National Park and Preserve, southeast Alaska. The broad and undulating gravel bed that stretches across the valley floor is actually the four mile-wide Kennicott Glacier, a dirt glacier as John Muir labelled such in southeast Alaska in 1879. The gravel layer rides atop the glacier from rockfalls...

Western Wildfire Increases Hail and Heavy Rain in Central US

By aerosols, Extreme Weather, Fire, rainfall

Western Wildfires Increase Extremeness of Weather in the Central US by a Third Climate change: Expect the unexpected. How can western wildfires increase the extremeness of weather in the Central US? Well, heat injected into the atmosphere enhances high pressure because heat rises and high pressure is rising air. This increase in high pressure increases…
