Giving up on 1.5C?

Posted on November 19, 2022 by ...and Then There's Physics

One of the talking points of COP27 is giving up, or compromising, on the 1.5oC target. The main reason is simply that the remaining carbon budget is very small. Essentially, to stop global warming requires getting human emissions to (net) … Continue reading →

Promises and perils of the Paris agreement?

Posted on June 2, 2019 by ...and Then There's Physics

A few people were sharing, on Twitter, a Science article called Promises and Perils of the Paris Agreement. It mostly seemed unobjectionable. It discusses the linear relationship between warming and emissions, and how this allows one to define carbon budgets … Continue reading →

Carbon budgets and the impacts of climate change

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

I’m somewhat stealing this from Stoat, but it’s an interesting topic, and it really originates from a tweet by Gavin Schmidt anyway 😉 I think this is correct. There's no connection to speak of between the impacts of carbon emissions … Continue reading →

Long-term climate goals

Posted on March 3, 2018 by ...and Then There's Physics

There was quite a lot of coverage last year about a paper by Millar et al. which suggested that the carbon budget that would keep warming below 1.5oC was greater than had been earlier suggested. I wrote about it here, … Continue reading →

Narrowing the climate sensitivity range?

Posted on January 20, 2018 by ...and Then There's Physics

There have been a couple of recent papers presenting analyses that claim to have narrowed the likely range for equilibrium climate sensitivity (ECS). One is Dessler et al. (currently a discussion paper under review) which suggests that the 500hPa tropical … Continue reading →

Carbon budget constraints

Posted on November 23, 2017 by ...and Then There's Physics

I’d been meaning to highlight a statement from Kevin Anderson for quite some time. A brief lull in postings gives me a chance to do so. It relates to the Paris goal of keeping global warming below 2oC. I haven’t … Continue reading →

A bit more about carbon budgets

Posted on September 27, 2017 by ...and Then There's Physics

I’ve been mostly at home today since we had a power cut at work and the site ended up being closed. So, I thought I would post a few more thoughts about the Millar et al. 1.5oC carbon budget paper. … Continue reading →

Own goal

Posted on September 22, 2017 by ...and Then There's Physics

I thought I might comment a bit further on the recent Millar et al. paper, [e]mission budgets and pathways consistent with limiting warming to 1.5 °C, that I discussed in this post. I’ve found the whole public dialogue about this paper … 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 →
