Worst case scenarios, or not?

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

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?

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

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

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

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

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
