The IEA's first net zero scenario (NZE), published in 2021, showed emissions peaking immediately and falling to net zero by 2050.
Today they published an update. Although we are behind on most things, solar and wind deployment moved EVEN FASTER than the first NZE suggested. A little ray of hope.

🚨🚨🚨 NEW REPORT ALERT 🚨🚨🚨
@climateanalytics.org has a new report out today that I’m really excited about. It’s all about 1.5ºC...
▶️ Is overshooting 1.5ºC inevitable?
▶️ Can we still get temperatures back below 1.5ºC?
▶️ If so, how?
If you’re interested in our findings, buckle up for a mega thread...

Something that's worth flagging about this report is the subtle pivot from "current policy" being the worst-case scenario to including discussions of backsliding. Most calculations presented include the USA meeting its new-but-Biden-era NDC commitments, which will formally elapse in Jan.
NEW: The latest climate pledges under the Paris Agreement have driven only a slight fall in predicted global temperature rise over the course of this century.
The UN Emissions Gap Report finds that implementing current policies would lead to up to 2.8°C of warming, down from 3.1°C. 🧵

One of the strongest, clearest increases in likelihood & intensity, attributable to climate change, I've seen in a complex index like fire weather - the more intense & frequent events in Greece & Türkiye are already outpacing efforts to adapt.

New research on limits to CO2 removal (CDR). CDR is key to our ambition to stop adding climate pollution to the atmosphere. Because it's uncertain how much will be delivered and it clearly comes with risks of social & environmental side-effects, legal issues arise. This paper provides an overview. 👇

To minimise risks associated with reliance on CO2 removal, states should prioritise pathways that minimise overshoot and dependence on removals to reach net-zero. Risks associated with high CDR dependence might render state action inconsistent with norms and principles of international law.
