The two-degree delusion?

Posted on February 16, 2018 by ...and Then There's Physics

Ted Nordhaus, of Breakthrough Institute fame, has a recent article in Foreign Affairs called [t]he two-degree delusion. Basically, it argues that we cannot possibly achieve this target without harming the poor, and that continuing to try and do so also … Continue reading →

More time …. really?

Posted on September 19, 2017 by ...and Then There's Physics

A recent paper about [e]mission budgets and pathways consistent with limiting warming to 1.5 °C essentially argues that it is still possible to follow an emission pathway that will give us a good chance of keeping warming below 1.5oC. More specifically, … Continue reading →

Temperature targets

Posted on July 6, 2017 by ...and Then There's Physics

I realise Michael Tobis is planning a follow-up to his post, but I thought would quickly pen this post about temperature targets, for example the Paris target of keeping the increase in global average temperature to well below 2°C above … Continue reading →

A new baseline?

Posted on January 28, 2017 by ...and Then There's Physics

Ed Hawkins and colleagues have a new paper called Estimating changes in global temperature since pre-industrial times, which Ed also discusses in this post. The basic suggestion seems to be that we should probably be defining pre-industrial as the period … Continue reading →

Zero emissions

Posted on December 26, 2015 by ...and Then There's Physics

David Roberts has a recent post that I’ve only just noticed called why zero is a better climate target than 2 degrees. The zero refers to net global emissions, not to temperature. The argument is essentially that zero is a … Continue reading →

1.5C?

Posted on December 12, 2015 by ...and Then There's Physics

I think that the negotiators in Paris are pretty close to reaching an agreement (may have already done so). There’s a draft version here. Maybe the most interesting aspect of the agreement is the paragraph below: Emphasizing with serious concern … Continue reading →

Censoring their own research?

Posted on November 30, 2015 by ...and Then There's Physics

This is going to be my last post about the whole 2oC pathways issue, I promise 🙂 I was wanting, however, to discuss this Washington Post article called The magic number. It quotes Kevin Anderson, whose work I’ve discussed before. … Continue reading →

The 2C fantasy?

Posted on November 27, 2015 by ...and Then There's Physics

In the run up to the Paris meeting there seem to be a number of people focusing on the idea that the 2oC limit is essentially now a fantasy. There’s a post by Andy Revkin, and there’s a Nature feature … Continue reading →

The 1C milestone

Posted on November 9, 2015 by ...and Then There's Physics

Just a quick post to highlight that – according to the UK Met Office – 2015 is likely to be 1oC above pre-industrial – well, 1oC above the 1850 to 1900 average. If you think that we should have a … Continue reading →
