What is the Paris agreement?

The Paris agreement is the first deal that unites all the nations on earth in tackling climate change. For the first time in history, nearly 200 countries agreed to curb greenhouse emissions. The agreement was signed on the 4th of Sept. 2016. Previously, a number of developed countries had signed the Kyoto protocol in 1997 but some countries failed to comply and the US quit. Now, the Paris Agreement is currently the only hope of curbing serious climate change. The pillars of the agreement include;

1. To keep global temperatures well below 2.0C (3.6F) above pre-industrial times and endeavour to limit them even more, to 1.5C
2. To limit the amount of greenhouse gases emitted by human activity to the same levels that trees, soil and oceans can absorb naturally, beginning at some point between 2050 and 2100
3. To review each country's contribution to cutting emissions every five years so they scale up to the challenge
4. For rich countries to help poorer nations by providing climate finance to adapt to climate change and switch to renewable energy.
