Resumen de Act now, not tomorrow
Anderson and Peters comment on the much-heralded Paris agreement on climate change that was due to come into legal force. Prime ministers and presidents will throw down the gauntlet to the scientific community: show how to hold the increase in the global average temperature to well below 2°C above pre-industrial levels and pursue efforts to limit the temperature increase to 1.5°C. The fast-diminishing carbon budgets associated with temperature rises across the century emphasize the challenge of delivering on the agreement. The mitigation pledges submitted in Paris last December will still lead to an ongoing rise in emissions as people keep burning fossil fuels, enough to squander the carbon budget for 1.5°C in five years and 2°C by 2030.
