A University of Cambridge professor has proposed a radical new centre for climate repair to reverse the damage humans are doing to the environment. The proposals would aim to roll back the harms of global warming and include refreezing the Earth’s polar regions and capturing carbon dioxide from out of the atmosphere.
Sir David, a former chief scientific adviser to the government, said that time “is no longer on our side” to tackle climate change.

“What we continue to do, what we do that is new, and what we plan to do over the next 10 to 12 years will determine the future of humanity for the next 10,000,” he said. Theoretical techniques of large-scale human intervention to drive climate change in a positive direction are part of an area of research known as geoengineering.

They could include spraying salt water high into the atmosphere in the Arctic to “whiten” clouds there and reflect heat back into space, as well as growing more vegetation to remove carbon dioxide from the air.
But the cost to research and implement these techniques safely has hampered most of these proposals.
