Cumulative and (probably) irreversible
This post may be written more in frustration than anything else, but I’ve had some recent discussions that have made me wonder if even those who spend their time thinking/writing/commenting about climate change fully appreciate that it’s a cumulative problem … Continue reading

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
Cumulative matters
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
