Paris climate change agreement enters into force

According to Guardian, the passage of the accord – the fruit of more than two decades of often tortuous international negotiations on combating climate change – was hailed by nations and observers around the world.

Under the agreement, all governments that have ratified the accord, which includes the US, China, India and the EU, now carry an obligation to hold global warming to no more than 2C above pre-industrial levels. That is what scientists regard as the limit of safety, beyond which climate change is likely to become catastrophic and irreversible.

Harjeet Singh, global lead on climate change for the charity ActionAid, added: “The Paris agreement sends a much-needed signal to politicians and industry that we have to build a new world, and this has to start now. However, the deal is not enough to keep people and the planet safe.”
