Solar Radiation Management Quotes

Many of the most science-fictional tools to fight climate change are untested, are almost impossible to truly test at planetary scale - we only have one planet after all. We're better off cutting our emissions so we don't need them.

NASA will send up a big sun shade that will be in orbit between the earth and sun and deflect 2 or 3 percent of the sunshine back into space. It would be cheaper than the international space station.

There are many theories about the best way to remove excess carbon from the atmosphere - some are ludicrous, others are at least worth study. The most commonly discussed plan is to lace the sky with reflective chemicals.

We are altering the most basic forces of the planet's surface - the content of the sunlight, the temperature and aridity - and that brings out the most powerful questions about who is in charge. If you wanted to give a name to this theological problem, I think you could say that we are engaged in decreation.

I was born behind the Iron Curtain, and I remember heated discussions about large-scale terra-forming projects, such as reversing the direction of the river Ob or putting up large reflectors into space to heat up Siberia.

For relatively modest amounts of sulfur dioxide injected into the atmosphere, you could easily cool Earth by 1% or more, if you want.

Geoengineering means changing the Earth's fundamental large-scale processes.

Geoengineering involves humans making intentional, large-scale modifications to the Earths geophysical systems in order to change the environment.

As for geoengineering, there have been serious general critiques that I think cannot be ignored, like Clive Hamilton's, along with many positive assessments. It is not a matter for subjective judgment based on guesswork and intuition. Rather, these are matters that have to be considered seriously, relying on the best scientific understanding available, without abandoning sensible precautionary principles.
