What are some examples of geoengineering?

Some geoengineering proposals focus on removing carbon dioxide from the atmosphere. Some examples include: ocean fertilisation, where iron dust dumped into the open ocean would trigger vast algal blooms that would absorb large quantities of carbon dioxide – this has been trailed with limited success.

Can Geoengineering Save Us?

Yet, as the authors state, even successful geoengineering would be a stopgap, much like Pinatubo's effect was: “But solar geoengineering is no panacea; it could compound some risks of climate change. It would only mask the warming effect of greenhouse gases. But it's not going to save the world from global warming.

Is geoengineering a good idea?

Long-established estimates show that solar geoengineering is at least 100 times cheaper than cutting emissions in offsetting the expected global temperature rise through 2100. A few grams of particles in the stratosphere can offset the radiative forcing of a metric ton of atmospheric carbon dioxide.

What is geoengineering and how does it work?

Geoengineering (literally "Earth-engineering") is the currently fashionable term for making large-scale interventions in how the planet works to slow down or reverse the effects of climate change. The first is to try to cool the planet by reducing the amount of incoming solar energy.
