Earth’s Energy Imbalance and Climate Response Time

 

James Hansen, Makiko Sato, Norman Loeb, Leon Simons, Karina von Schuckmann Our judicious choice of graphs for Global Warming in the Pipeline[1] (submitted to Oxford Open Climate Change, available here with an added list of acronyms) squeezed out a graph of Earth’s energy imbalance (EEI, Fig. 1 above). EEI is the net […]

James Hansen and Makiko Sato

Global temperature in June was +1.13°C (relative to the 1880-1920 base period, which is our best estimate of preindustrial temperature); it was +0.85°C relative to the 1951-1980 […]

Fighting the Battles, Winning the War

Kayford Mountain, or what was a mountain.

by James Hansen, 1 June 2021

The battles to slow human-made climate change have been fought bravely by ad hoc groups of concerned citizens – trying to stop pipelines, coal mines, fracking, etc. Winning a battle helps, and fights are beginning to be won, including confrontations […]

2020 Was The Warmest Year on Record

It capped the warmest decade on record

George Harvey

In mid-January, a report by James Hansen et al. was posted at the Columbia University web site. “Global Temperature in 2020” makes clear that each of the last six years is one of the hottest six years ever recorded. The hottest year had been […]

Global Warming Acceleration

(GET editor’s note: We are providing the first couple of paragraphs of this article and a link to the website at Columbia University. We do want all of our readers to be aware of the conclusion, however, and so we start by quoting the article’s last paragraph:

Global temperature prognostication: 2021 will be cooler than […]

A socially and environmentally just way to fight climate change

September 9, 2020

By James E. Hansen And Daniel H. Miller, Opinion Contributors

A majority of the public is in favor of action on climate change, and putting a fee or tax on the carbon content of fossil fuels is generally accepted — including among conservatives — as a key method for reducing greenhouse gas […]

It’s All Hunky-Dory, but…

06 July 2020 James Hansen and Makiko Sato Well-meaning souls, rightfully concerned about the effect of “gloom-and-doom” talk on young people, say that everything is hunky-dory, climate change impacts are exaggerated (they often are) and climate change is not a serious threat (unfortunately, it is).

Let’s look at reality, real data for the real […]

Oh, Canada!

by James Hanson, July 10, 2019

North of the border, there is bad news and good news. Canada’s fossil fuel CO2 emissions remain stubbornly high, despite decreased coal use. Emissions in 2018 were 7% greater than in 1997, the year of the Kyoto Protocol. I don’t even want to look up what Canada promised – […]
