Get a heat pump, get a job installing insulation or selling EVs, go to local council meetings in support of bike lanes or solar parks or dense housing near public transport. Run for political office, or at least vote. Recommend flight-free holiday destinations to others. (Delete as applicable).

my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"

Carbon capture technology has promised much, but delivered relatively little. But now it's finally being rolled out to cement plants, offering a decarbonisation route for one of the economy's dirtiest sectors www.newscientist.com/article/2497...

Could we have cracked one of the world's toughest climate problems?

It is almost impossible to make cement without emissions, but carbon-capture-and-storage technology is finally being deployed to decarbonise the sector

Atmospheric hydrogen is rising, which may be a problem for the climate

Ice core records of atmospheric hydrogen reveal a huge rise in concentration since the Industrial Revolution which has contributed to global warming – and could sway the debate over hydrogen as a fuel

Cutting air pollution has been good for public health, but it has unleashed a surge in climate warming... My latest feature for @newscientist.com explores how dirty air has been cooling the planet, and what happens when that cooling effect is ripped away www.newscientist.com/article/2494...

Is Earth’s climate in a state of 'termination shock'?

Cleaning up air pollution has saved millions of lives, but it has also given us an inadvertent taste of a nightmare climate scenario. The race is on to understand how bad it could be – and how to swer...

Much less CO2 can be safely stored underground than we thought, scientists warn

If we simply dump ongoing fossil fuel emissions underground, we may run out of space…

www.newscientist.com/article/2494...

We may have 10 times less carbon storage capacity than we thought

Storing carbon dioxide underground is seen as a way to mitigate climate change, but the world could run out of safe storage space within 200 years if we keep on burning fossil fuels

This is bad

The research found that if carbon emissions continued to rise, 70% of the model runs led to collapse, while an intermediate level of emissions resulted in collapse in 37% of the models. Even in the case of low future emissions, an Amoc shutdown happened in 25% of the models.

Scientists have warned previously that Amoc collapse must be avoided “at all costs”. It would shift the tropical rainfall belt on which many millions of people rely to grow their food, plunge western Europe into extreme cold winters and summer droughts, and add 50cm to already rising sea levels.
