“One thing we have to do immediately is to stop deforestation”

  • Alt

Did you know that water vapour is a greenhouse gas? In this video, scientist George Woodwell shares some surprising insights into global warming, as well as four solutions that we need to pursue right now if we want to combat the climate crisis.

We all know that human activity has increased the CO2 content of the atmosphere since we started burning fossil fuels, but what’s less well known is that vapour – also a heat-trapping gas – from the warming waters of the melting Arctic is building energy into the atmosphere to drive storms. 

Similarly, as the soils of the Arctic thaw, the huge depths of organic matter in the tundra is releasing methane as well as CO2 into the atmosphere, warming the planet even more. 

What can we do? George is very clear. Eliminate fossil fuel consumption, refreeze the arctic, shift to renewable energies – and stop deforestation immediately. The role of photosynthesis is so key that in the summer, for example, it pulls the CO2 concentration in the atmosphere down by several parts per million.
