The Critical Decade

That's the name of the Climate Commission's report on the science of climate change. In short, the report says

1. The climate is changing.
2. We are already seeing the impact
3. Human activity is the cause
4. From now to 2020 is vital

Points 1 to 3 are already well known. Point 4 is best illustrated by this diagram.


For a given amount of pollution, the earlier we start reducing emissions, the less dramatic the reductions need to be.
