Five technologies fighting the climate crisis

With global temperatures rising the threat of a climate crisis has never been closer. Renewable energy like solar and wind power for a part of the solution, but if we are going to stem the tide of climate change we might have to start looking towards more innovative technologies.

These new technologies cannot solve the climate crisis on their own, but integrated with larger-scale changes in policy, and traditional green technologies like solar, they could be the new weapons in humanity's arsenal against a changing climate.
