There's very little reason to assume 30-year linear warming extrapolation.
Emissions, forcings, Earth's Energy Imbalance and (especially variability corrected) temperature observations all indicate acceleration of global warming.
We should prepare for reaching +2.0°C soon!

"Just half a pound of the stuff may remove as much carbon dioxide as a tree can". What the f**k does that even mean?
A mature tree removes ~25 kg of CO₂/year. This "new powder" is a sorbent with a capacity of 0.96 mmol/g, so that's 0.0096 kg of CO₂ per 0.5 lbs. You'd need 1305 lbs to equal a tree.

New powder that captures carbon could be ‘quantum leap’ for industry
A ‘covalent organic framework’ can be used to capture carbon to store it or convert it for industrial use

How unusual is current post-El Niño warmth?
Global temperatures rose earlier and have potentially remained elevated longer than in any prior El Niño event since at least 1940.

How much longer can we keep using the IPCC AR6 1.5°C scenarios (limited overshoot) for percentage reductions, net zero years, etc, given that we are currently not even remotely on track?
Starting today, the percentage reductions will be higher, net zero year earlier (all else equal).

The average American emits more CO₂ in one week than an average person in low-income countries does in one year.

If you see the atmosphere as a commons - a natural wealth for everyone to access equitably and sustainably - then it's not hard to see how deeply unjust the #COP29 $300bn per year goal from industrialised countries is, when historical responsibilities for excess emissions are taken into account. 1/

I'm fascinated by the intuitive differences in people's response to going to space
Some people: "Why should we go? What will be the practical applications? Aren't there better priorities on earth?"
Other people: "It's just obvious!!! How can you not see it?"
