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…

Another Big Antarctic Calving From New Underice Melt

By | Abrupt changes, Antarctica, communications, Glaciers, ice sheet, submarine channel, West Antarctic Ice Sheet

Another Big Antarctic Calving From New Underice Melt Ice scientists have been warning us since 2006 that the West Antarctic Ice Sheet (WAIS) has begun its collapse. Giant icebergs are a symptom that collapse initiation is underway. The continuing laissez-faire attitude of the press to…

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…

Sea Level Rise Scenarios Starting to Catch Up With Prehistory

McClatchy reported on a new NOAA sea level rise impact report and made some very good points. But a lot of the true meaning is left out. I like to use well publicized journalism like this to be able to quickly get to the most…

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…

West Antarctic Ice Sheet (WAIS) Collapse: The Latest Case for Zero Warming

By | Abrupt changes, Antarctica, Climate Policy, Climate Reform, ice sheet, Oceans, Policy, Sea Level Rise, Strategy, underice

New research has for the first time defined the tipping point between a stable WAIS and an Antarctica that collapses uncontrollably. Potsdam Institute researchers (Levermann and Feldmann) tell us is that if we do not return our oceans to their preindustrial temperature by 2050, we…

NOAA — Ice Sheet Collapse in Our Time: Zero Warming Climate Solution

By | Abrupt changes, adaptation, Antarctica, Arctic, Climate Policy, CO2, CO2 Removal and Sequestration, Emissions, Emissions Scenarios, Greenland, ice sheets, in-depth and Popular Press, modeling, Negative emissions, Sea Level Rise, Solutions, West Antarctic Ice Sheet

We have delayed too long and now must urgently reduce the load of warming gases already emitted to our sky. We have been warned this would happen for decades, we just didn’t think it would happen so soon. This is exceedingly bad news, though the…

Saved They Say: Emissions Have Flattened — Climate Mirage

And they also say that Elvis is not dead. But alas… the answer is no, we are not saved. Things are actually getting worse because of the so-called “flattening emissions.” This needs to be said over and over: the only way to treat the vast…

First published on Truthout December 26, 3015, by Bruce Melton. Climate science is way out in front of climate policy. Commitments at the United Nations Climate Conference in Paris pale in comparison to those from the Kyoto Protocol with its beginnings in the Rio Earth Summit…
