“The Paris agreement is a historic turning point for the whole world. One of the most remarkable outcomes of the agreement is that its objective is to “pursue efforts to limit” global warming to 1.5°C above preindustrial, while holding warming “well below 2°C”.
“In doing so, the global community has recognised that the risks of global warming are far greater than previously understood, and that the scientific basis compelling very urgent action has never been stronger.
“It is a victory for the most vulnerable countries, the small islands, the least developed countries and all those with the most to lose, who came to Paris and said they didn’t want sympathy, they wanted action.
“The Paris Agreement calls for all the world’s nations to cooperate to peak global emissions as soon as possible and to undertake rapid greenhouse gas emission reductions bringing emissions to net zero in the second half of the century. Importantly, this is to be done taking the best available science into account.
“While the agreement is itself historic, the challenges ahead in achieving it will dominate the 21st-century. The agreement has been made at a time when national greenhouse gas emission reduction contributions for 2025 and 2030 together far exceed the levels needed to hold global warming well below 2°C, let alone limit to 1.5°C.”
