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…

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…

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…

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…

Critical Climate Time Frames: New Strategy is Needed

By | Abrupt changes, alternatives, Climate Policy, Climate Reform, Negative emissions, Sea Level Rise, Solutions, Strategy

Scientists have been planning for how to implement a transformation to an alternative energy infrastructure for more than several years now. Jacobson 2013, represents years of effort and others have been doing the same. We know how to evolve our energy infrastructure, how long it…

An Easier Solution to Climate Change

The driver of our climate system has changed in the last two decades from one that is controlled by annual emissions, to one that is controlled by already emitted CO2. This means that previous strategies to control annual emissions are no longer meaningful and 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

By | aerosols, Antarctica, Climate Policy, CO2, CO2 Removal and Sequestration, Emissions, Fracking, ice sheets, Negative emissions, Sea Level Rise, West Antarctic Ice Sheet

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…
