Could hand-made humans may hold the key to saving the world?

ee f x

Human-induced climate change is one of the biggest problems that we face today. Millions could suffer hunger, water shortages, diseases and coastal flooding because of climate change. The latest science suggests that we may be near or even beyond the point of no return.

Some scientists and policy makers are therefore proposing that we take seriously the idea of geoengineering – that is, large-scale manipulations of the earth, such as spraying sulfate aerosols into the stratosphere to alter the reflectivity of the planet or fertilising the ocean with iron to spur blooms of carbon-sucking plankton. However, geoengineering seems too risky.

I propose that we consider another solution to the problem of climate change that has not been considered before and that is potentially less risky than geoengineering. Elsewhere my colleagues and I have called this solution ”human engineering”. It involves the biomedical modification of humans to make us better at mitigating, and adapting to the effects of, climate change.
