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…

  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…

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…

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…
