Worst case scenarios, or not?

Posted on October 6, 2019 by ...and Then There's Physics

I’ve been thinking a bit more about the debate around high emission scenarios, which I found rather frustrating. I think it’s an important issue, but the manner in which some people choose to frame this does make it difficult to … Continue reading →

Talking solutions and motivating action

Posted on March 6, 2018 by ...and Then There's Physics

There’s been a lengthy Twitter discussion about scientists moving away from simply discussing the science of climate change, to talking about solutions and motivating action. I broadly agree with this; I do think that the main discussion should be about … 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 →

5000 GtC

Posted on January 13, 2016 by ...and Then There's Physics

The advantage of working at a university, is that you get the opportunity to attend interesting seminars, especially if Kit Carruthers reminds you (on which note, I also discovered that Kit submitted his PhD thesis last month). The talk today … Continue reading →

Sensitivity to cumulative emissions

Posted on December 2, 2015 by ...and Then There's Physics

Something I’ve mentioned here quite regularly is the idea that warming depends roughly linearly on cumulative (total) emissions. This is slightly counter intuitive, in that warming depends logarithmically on atmospheric CO2 concentration. The reason is essentially that it incorporates climate … Continue reading →

If wishes were horses

Posted on November 28, 2015 by ...and Then There's Physics

There’s a proverb which goes if wishes were horses, beggars would ride, which basically means that it’s useless to simply hope that everything will be fine, it’s better to actually take action. If it isn’t already, it really should be … Continue reading →

Climate change by numbers

Posted on March 3, 2015 by ...and Then There's Physics

I watched the much-hyped BBC4 show climate change by numbers and thought it was pretty good. It covered 3 basic numbers; why we think global surface temperatures have risen by 0.85oC since 1880, why we’re 95% (or more) sure that … Continue reading →

Cumulative matters

Posted on December 15, 2014 by ...and Then There's Physics

I was contemplating writing a post about a discussion I had on Twitter regarding whether or not we should focus on adaptation while developing technology, but I don’t really have the time now. The one comment I will make is … Continue reading →
