Warming commitments

There’s been quite a lot of recent discussion about warming commitments. It started with an article by Bob Berwyn called Net Zero Emissions Would Stabilize Climate Quickly Says UK Scientist, followed soon after by one saying [w]arming already baked in … Continue reading

The effect of permafrost on the ZEC

I’ve written a number of posts about warming commitments, in particular the zero emission commitment (ZEC). In other words, how much additional warming will there be after emissions get to zero. The answer is that on multi-decadal timescales [the ZEC] … Continue reading

CO2 emission reductions

At the risk of sounding rather arrogant, I find myself getting more and more frustrated by people justifying their position on the basis of a flawed understanding of the scientific evidence. One that seems particularly prevalent at the moment is … Continue reading

‘Net zero’

There’s been some recent debate about the term ‘net-zero’. Just to give some basic background, given that the zero emission commitment is close to zero (i.e., when we get anthropogenic emissions to zero, global surface temperatures should soon stabilise) means … Continue reading

But RCPs

Just as I thought I was out the ClimateBall Gods pull me back in. The “but RCP” flythe club got the best of me. For the time lost I found talking points for my Bingo. More on this project in … Continue reading

Promises and perils of the Paris agreement?

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

The two-degree delusion?

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

Carbon budget constraints

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 committed warming

On a number of occasions I’ve pointed out that our warming committment is not actually the equilibrium temperature to our current atmospheric concentration because, if we halted all emissions, atmospheric CO2 would drop as the natural sinks took up more … Continue reading

Temperature targets

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
