Removing CO2 from the atmosphere won’t save us: we have to cut emissions now

Description

Over 190 countries are negotiating in Paris a global agreement to stabilise climate change at less than 2℃ above pre-industrial global average temperatures.

For a reasonable chance of keeping warming under 2℃ we can emit a further 865 billion tonnes of carbon dioxide (CO₂). The climate commitments to reduce greenhouse gas emissions to 2030 are a first step, but recent analyses show they are not enough.

So what are the options if we cannot limit emissions to remain within our carbon budget?
