1/7 Climate progress - why I'm celebrating news from the UK and DK today

... a short thread
2/7 As an outspoken critic of aspirational #NetZero pledges, there are several big worries that motivate my concern. I'll focus on two here. First, they enable delay in emissions reductions, by potentially replacing accelerated mitigation with future speculative carbon removals.
3/7 Second, they enable delay in closing down fossil fuel use and extraction - allowing even oil companies and airlines to claim carbon neutrality simply by buying up removal offsets (that might not even be additional, or permanent).
4/7 So while the UK's adoption of a 68% emissions reduction target by 2030 is just another target, it is explicitly about emissions cuts (not offsets), and on a timescale that demands immediate action. Of course, I'd rather it were even tougher, and included shipping & aviation.
5/7 And while Denmark's decision not to let further oil extraction contracts in the North Sea doesn't affect existing operations, and leaves oil flowing until 2050, it draws a line in the sand that other oil-producing nations would appear unable to conceive.
6/7 If we are going to successfully shut down fossil fuel industries, stopping expanding them is an important step in that direction. Of course we need a just transition for workers, and much faster action, but this is a step worth welcoming.
7/7 Steps like these offer some hope of turning vague #NetZero pledges into meaningful climate action. Theres much more to do to deliver climate justice, but these are at least both moves in the right direction.

1/15 Today a group of 23 climate researchers published a myth-busting article on net-zero and offsetting in Sweden’s Dagens Nyheter (Daily News). dn.se/debatt/vilsele…
In this thread I paraphrase our arguments in English ...
2/15 Reaching net-zero by 2050 is not enough to solve the climate crisis: carbon budgets will be exceeded before then at current emission rates, and we cannot rely on speculative and uncertain negative emissions technologies to compensate.
3/15 Nor can ‘nature based solutions’ compensate for continued fossil emissions. While important, recapture of carbon by NBS is limited, slow, and insecure in a still-changing climate.

That 10 point plan for the climate ... some cautionary notes from me ... (thread)
1/10 Quadruple offshore wind - great, a target, with a deadline, and building on past trends. But nothing about cheaper onshore wind - a huge missed opportunity.
2/10 5GW of low carbon hydrogen capacity. Exaggerated and poorly targeted. Hydrogen is a niche measure for some hard-to-decarbonise uses. As a mainstream energy vector its another 'technology of prevarication' putting off systemic change.

In my chapter for “Has it Come to This: the promises and perils of geoengineering on the brink” rutgersuniversitypress.org/has-it-come-to… I seek to explain why promises of enhancing justice through #geoengineering are delusional in contemporary politics

/thread
2/9 Right now, geoengineering techniques are being co-constructed with political regimes inside the dominant (neo)liberal social imaginary, as sustaining innovations for the political and cultural maintenance of elite privilege and Northern domination.
3/9 Current geoengineering research and advocacy typically fails to properly recognize all those that would be affected by it, and consistently presumes and privileges certain (Northern, liberal) forms of knowledge, expertise, moral theory, and subjectivity.

Just published, my new article on #mitigationdeterrence from #carbonremoval (in #ClimaticChange ) link.springer.com/article/10.100…
What is this about, and why do I think it important?

A thread 1/15
Most climate scientists are so concerned about the risks of climate change that they typically support 'all of the above' ... in other words, behaviour change, energy efficiency, decarbonization, low-carbon technology and carbon removal (not unreasonable on the face of it) 2/15
Our previous work in @NatureClimate rdcu.be/b3FEB shows that such responses are not simply additive, and while some may interact positively, galvanising more action, others - especially promises of future technological solutions - tend to undermine emissions cuts 3/15
