Why are climate change impacts so much worse than projected? What does it mean? Why don’t we do something? In a nutshell, science is conservative, it’s slow, and the great climate consensus that has evolved to protect our society compounds the understating nature of the industry…

  New Evaluation of Climate Models Reveals Abrupt Changes Ahead of Schedule It’s not the averages that will mess up your hair, it’s the gusts. This work on modeling the unmodelable (Drijfhout 2015) is a couple of years old now, but it gives enormous insight into…

Sing Delay, Delay, Delay When serious discussions about global warming gases and fossil fuels began in the 1980s, all that was needed to prevent what would become labeled as dangerous climate change was a reduction of the emissions of global warming gases. Since that time,…

Very Large Negative Emissions: Beyond Paris Emissions Reductions to a Safe and Healthy Climate

By | Abrupt changes, Antarctica, Climate Catastrophes, Climate Policy, Climate Reform, climate solutions, CO2 Removal and Sequestration, Emissions Scenarios, Extreme Weather, Impacts, modeling, Negative emissions, Policy, Scenarios, Sea Level Rise, Strategy, West Antarctic Ice Sheet

James Hansen, 32 year director of the U.S. national climate modeling agency, the NASA Goddard Institute for Space Studies (1981-2013, now retired), has had a new fundamental piece of climate work published. His team looks at the negative emissions required–in addition to various scenarios for…

When Does Climate Catastrophism Become Climate Reality?

By | Abrupt changes, adaptation, Antarctica, Climate Catastrophes, Climate Culture, Climate Policy, economics, Extreme Weather, flood, modeling, Policy

  Climate catastrophism, or as it will be called soon, reality, is getting tougher to pin down with every new climate catastrophe. A real page turner on the subject is Lynas, Six Degrees: Our Future on a Hotter Planet. It’s from 2007 and hyperbolic for…

The greatest climate dude of all time has done it again. James Hansen, 32 year director of the U.S. national climate modeling agency, the NASA Goddard institute for Space Studies, published a new fundamental piece of climate work last month. He looks at the additional…

Global Warming vs. Abrupt Change — What’s the Difference?

By | Abrupt changes, Antarctica, Arctic, Glaciers, Greenland, Gulf Stream, ice sheets, modeling, Sea Level Rise, West Antarctic Ice Sheet

Something that is not clear in the overall climate discussion is that global warming is a radically different beast from abrupt change.  We hear abrupt change bandied about, but often it is not well defined. It appears to many that global warming is abrupt change…

Ice Loss During Antarctic Cold Reversal May Spell Trouble for WAIS Collapse

By | Abrupt changes, Antarctica, Glaciers, Greenland, Gulf Stream, ice sheet, Oceans, underice, West Antarctic Ice Sheet

Fifty-two feet of sea level rise occurred in 400 years, 14,500 years ago with ocean and collapse conditions similar to today. We were coming out of the last ice age then, but then, forcing was thousands of times less than today. Our climate’s most meaningful…

Sea Level Rise: IPCC Averages, Extremes From Latest Publishing, and Ice Sheet Collapse

By | Abrupt changes, adaptation, Antarctica, Climate Policy, Climate Reform, CO2 Removal and Sequestration, Extreme Weather, global warming psychology, Greenland, Gulf Stream, ice sheet, ice sheets, Impacts, Legacy Policy, Messaging, Negative emissions, Policy, Psycho, Sea Level Rise, Solutions, Strategy, West Antarctic Ice Sheet

It’s not the averages that are troublesome. The understating reporting of scientists, journalists and climate science consensus organizations is one of the most confounding parts of climate change today. It’s the extremes that matter, yet extremes are viewed as “uncertainty” in a way almost entirely related…
