The Greenlandification of Antarctica Antarctica is beginning to behave more like Greenland, with surface melt, ice dynamics, and climate feedbacks in Antarctica exhibiting "Greenland-like” traits, which have major implications for sea-level rise projections.

The Greenlandification of Antarctica - Nature Geoscience
Climate and ice sheet processes in Antarctica increasingly reflect those observed earlier in Greenland. Applying process insights from Greenland can improve projections of future Antarctic ice and climate behaviour.

🧵🧪 In session on policy and societal requirements at the Royal Society discussion meeting today, Prof Hans-Otto Pörtner, former Co-Chair of the IPCC Working Group II, stated that he thinks keeping global temperature rise "below 1.5 [°C above pre-industrial] is probably now out of reach".

This would be laughable if it wasn't so serious: yet again, the Tories are claiming that we can get "all our oil and gas" from the North Sea and that we should be doing even more to support the industry to extract. There are several reasons why we should treat this with maximum scepticism:

While it's very funny to watch The Metals Company whine about the deep ocean oxygen discovery they helped fund, I worry that this only the start. Climate tech startups want science to support their business case, but many are going to discover that science is about reality, not their bottom line 1/2
