Geoscale engineering to mitigate climate change

The Royal Society today published a series of papers outlining potential methods for geoscale engineering as a way to tackle climate change.

Articles in the journal Philosophical Transactions of the Royal Society propose macro-engineering options as a response to global warming.

In the preface of the journal, experts Brian Launder and Michael Thompson express concerns that politicians are not doing enough to combat rising CO2 levels in the atmosphere.

"There is increasingly the sense that governments are failing to come to grips with the urgency of setting in place measures that will assuredly lead to our planet reaching a safe equilibrium.

"Some scientists and engineers have been proposing major 'last-minute' schemes that, if properly developed and assessed in advance, could be available for rapid deployment, should the present general concern about climate change be upgraded to a recognition of imminent, catastrophic and, possibly, irreversible increases in global temperatures.

"While such geo-scale interventions may be risky, the time may well come when they are accepted as less risky than doing nothing."

Schemes could include "Albedo Enhancement" schemes to reflect energy from the sun back into space, and removing carbon from the atmosphere and placing it into the depths of the ocean.
