Department of Energy Issues Report Evaluating Impact of Greenhouse Gasses on U.S. Climate

[John Nissen]

Hi everyone, 

No doubt the time for comment on this report [1] has passed. But there will be a vacuum of reliable information about the state of the planet which PRAG could fill, correcting some of the information in the usual NOAA report. We can gather together much of the material we have written over the past few years. We can include trajectories showing that an emissions reduction policy would lead to catastrophe, with or without CDR. But reduction of the levels of greenhouse gases in the atmosphere is essential for long-term sustainability: therefore a combination of emissions reduction, CDR and methane suppression is essential for the longterm. 

We can include targets for climate intervention to avoid tipping point catastrophe, e.g. causing the Arctic temperature to peak before 2030 and global temperature before 2035.

Also we can note that, without global cooling intervention, the planet is heading for over 2.0C global warming by 2040, which could cause attempted mass migration by as many as 2 billion people. And, without Arctic cooling intervention, the planet is heading inexorably for ~9 metres of sea level rise, 2/3 coming from the Antarctic, assuming our planet follows a similar trajectory to the end Eemian; if not there could be many metres more.

The reversal of climate change and the possibility of planetary restoration can be mentioned at the end.

Cheers John
