Why we must keep carbon unburned (online)

We need to stay below 1.5 Degrees: Un-burnable Carbon overtakes Peak Oil

While the peak oil conversation has been very important in the first decade of the 21st Century, climate change has now almost eclipsed this issue. Now that there is increasing scientific certainty that to be safe humanity would be wise to keep global warming below 1.5 degrees Celsius, the issue is less whether and when we will run out of fossil fuels and much more how we will manage to agree on a global carbon budget and declare almost 80% of the remaining fossil fuel reserves as unburnable. While the potential fossil fuel reserves left might be twice as much as the current listed reserves, the carbon budget we have to stick to in order to have 50% chance to stay under 1.5 ºC of global average warming is less than a fifth of current fossil fuel reserves.
