There was already dramatic evidence that our planet is undeniably warming before 30 December 2015, when the world heard that the ice at the North Pole was melting. (The temperature on 30 December 2015 was, by some reports, 33ºF [0.7ºC], 50ºF above average).
And yet one immediate, effective way to fight climate change and save polar ice caps is half a world away, in the tropics. Tropical forest conservation and restoration could constitute half of the global warming solution, according to a recent peer reviewed commentary in Nature Climate Change.

Reducing carbon emissions, as the nations of the world promised to do in Paris last month, is essential, but simultaneously pulling carbon out of the atmosphere (which is what rainforests do) would immediately and significantly reduce atmospheric carbon dioxide (CO2) at a surprisingly low cost, providing a crucial bridge to a post-fossil fuel era.

While it is crucial that we transition away from the use of fossil fuels, the reality is that rainforest protection can happen much more quickly.

The potential of rainforest conservation to address global warming should be enough to galvanize massive worldwide rainforest conservation efforts. The natural regrowth and subsequent protection of hundreds of millions of acres of degraded rainforest would result in massive absorption of carbon as the trees grow. While it is crucial that we transition away from the use of fossil fuels, the reality is that rainforest protection can happen much more quickly.

But that is only part of the story.
