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 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…
A review of Ripple et al., World Scientists’ Warning of a Climate Emergency 2022, Bioscience, October 26, 2022. The report opens, “We are now at “code red” on planet Earth. Humanity is unequivocally facing a climate emergency. The scale of untold human suffering, already immense, is rapidly growing with the escalating number of climate-related disasters….
Arctic Sea Ice – More Than Half Gone With Five Times As Much Warming Just what do all the squiggly lines mean? To start with, the way science is shown to us civilians is a bit misleading generally. What we hear much of the time as the “new record sea ice extents” is based on…
We have all seen it, at least in the news. Most of us have been impacted by it because it is all around us. Extreme weather events have increased in intensity. Our climate has changed and as the modelers said 30 years ago, extremes have increased. In the future, expect further increases to triple what…
First published on Truthout, March 5, 2015. Greenland is warmer than it has been in more than 100,000 years and climate disrupting feedback loops have begun. Since 2000, ice loss has increased over 600 500 percent, and liquid water now exists inside the ice sheet year-round, no longer refreezing during winter. Complete Article
