Context: In their Limiting Overshoot report published earlier this year, UNEP confirmed that we’ve been too slow at cutting greenhouse gas emissions to avoid exceeding 1.5°C without a period of ‘overshoot’.
We can still limit how far we overshoot, how long it lasts, and how much harm it causes.

On one hand I get not wanting to overshoot but you swept fucking Texas, stop being afraid. 1994 is OVER.
Jon Ossoff put up German 7 Brazil 1 results by linking corruption with tarrifs and affordability.
"The American people don't want us to get even; they want us to get things done on their behalf."
House Minority Leader Hakeem Jeffries, who is now poised to become the next House Speaker, says that Democrats will focus on affordability concerns and not retribution after their midterm wins.

Usage of the term "overshoot" should come with conditions to make explicit the implicit reliance on CDR. How many gigatonnes of carbon removal are we talking about? People who hear "overshoot" can then judge for themselves whether it is plausible or not

1,5° ist erreicht. EU spricht jetzt von 3° in 50-70 Jahren. UN gab 1,8° als neue Schwelle aus, die nach Overshoot nicht überschritten werden darf – dann ist Rückkehr auf 1,5° möglich. Das sollte Ziel sein. Nicht Normalität simulieren, als ließe sich 3°-Welt mit Hitzeschutz regulieren.

What a statement:
"The bottom line is that the world is not ready to adapt to current climatic conditions, never mind what overshoot of 1.5°C will bring."
"The bottom line is that the world is not ready to adapt to current climatic conditions, never mind what overshoot of 1.5°C will bring."
As the 🌎 heads for warming above 1.5°C, climate adaptation is too slow.
Even if public adaptation finance tripled by 2035, it would only cover 20-29% of developing countries' needs.
More funding is needed to protect lives & livelihoods as impacts grow.

Um das zu verstehen, muss man aber hinter Schlagzeilen schauen, was unterstreicht, wie wichtig Berichterstattung dazu wäre.

We now know that we will overshoot the 1.5C climate anomaly target. It’s well past time we take concerted action to mitigate anthropogenic #GHG climate forcing. The good news is #renewables+storage are cheaper than #fossilfuels, better for the #environment, #climate & #publichealth. 🧪💡🔌☀️💨💧🔋

Snow and ice respond rapidly to every fraction of a degree of warming, but most of these systems will take centuries to millennia to recover after overshoot, especially if tipping points are crossed.
