🚨Geoengineering isn’t the climate “magic bullet” it’s often sold as
❗️Schemes like Stratospheric Aerosol Injection (SAI) include spraying particles to cool the atmosphere but don’t address the root cause of #climatecrisis like greenhouse gas emissions.

Changes in surface air temperature (°C, left column) and precipitation (mm/day, right column) for 1pctCO2 (red line) and G2 (blue line) simulations relative to the piControl condition for the globe (top row, JJA mean), tropics (middle row, JJA mean), and Indian monsoon region (bottom row, JJAS mean). Lines show the multi-model mean and the shadings show the intermodel standard deviation. The dashed vertical line shows the time of termination of geoengineering in the G2 simulations.

Stardust says it’s important to pursue the possibility of solar geoengineering because the dangers of climate change are accelerating faster than the world’s ability to respond to it, requiring a new “class of solution … that buys us time and protects us from overheating.”

Stardust says it’s important to pursue the possibility of solar geoengineering because the dangers of climate change are accelerating faster than the world’s ability to respond to it, requiring a new “class of solution … that buys us time and protects us from overheating.”

Also: I constantly see this line about "buying time" (KSR says in the pod too).

As if we haven't known about the exact nature of this problem since before I was born??? This is transparently not about 'more time', because they're talking down mitigation

So, in this episode of @the-breakdown.bsky.social, Kim Stanley Robinson says 'no one is proposing geoengineering as a replacement for mitigation'. Lots to agree w/ KSR in this ep but this isn't right. A nice example:

Today I learned that a majority of African nations are calling for a global governance mechanism for non-use of solar geoengineering.

Important to know!

The Guardian view on solar geoengineering: Africa has a point about this risky technology | Editorial Editorial: Sun-dimming risks putting the planet’s thermostat under Donald Trump’s control. Better to adopt the precautionary principle with high-stakes science
