Climate change? Yes, we can.

摘要

IT MIGHT seem bizarre that I'm talking about climate change when we're all faced with a huge pandemic. But many of us believe that the bigger threat facing us is climate change. What I want to show is that by dealing with the impact of this pandemic, we can also deal with climate change. We can have win-win solutions. The first thing to realise is that climate change science is really old. In 1856, the US scientist and feminist Eunice Foot took two glass tubes, put CO_2 in one and normal air in the other, stuck a thermometer in each and left them out in the sunshine. She saw the one with CO_2 heated up quicker, got hotter and stayed warmer for longer. It wasn't much later that in London John Tyndall measured the "radiation effect", the actual effect of heat absorption by gases in Earth's atmosphere.
