As the agreements in Durban do not propose additional action before 2020 the risk of exceeding 2°C remains very high. Action to implement the Durban Agreements will need to be quick to increase emission mitigation and hence have a chance at reaching this goal. Catching up on postponed action is costly and the technological and economic options required to do so are largely untested – or unknown. The Climate Action Tracker estimates that global mean warming would reach about 3.5°C by 2100 with the reduction proposals currently on the table.
