We can limit global warming to 2℃ – here’s how

The Intergovernmental Panel on Climate Change has just issued its 5th  Assessment Report. This represents the international scientific consensus on the state of climate change, its human causes, and what we need to do to keep global warming within the hopefully safe limit of 2℃ above the pre-industrial level of greenhouse gases in the atmosphere – before we starting running our economies on fossil fuels.

The short answer is that we have to rapidly reduce greenhouse gas emissions from burning fossil fuels. That means leaving fossil fuels in the ground, reducing energy use and increasing the use of renewables – including networked renewables over large regions, such as the whole of Europe.

We are at the Carbon Crossroads and need to take the road to 2℃
