If in the next few decades all countries of the world do not switch to renewable energy sources, then the Earth is threatened with catastrophic consequences.

This "Observer" was told by the expert of the National Ecological Center of Ukraine Irina Stavchuk.

"In order to keep global warming in a framework that does not lead to disastrous consequences, all countries of the world should by 2050 switch to renewable energy sources and escape from fossil fuels. It's all serious.. Because the further these measures are postponed, the less chance that on our planet it will be possible to prevent a catastrophe.

If the US does not implement any policies to reduce greenhouse gas emissions, then it will be very difficult for the world to compensate for this at the expense of the actions of other countries, "said Stavchuk.

As reported by the "Observer", US President Donald Trump can announce the withdrawal of his country from the Paris Agreement on Climate.

Recall that the withdrawal from the Paris agreement on climate was one of Trump's election promises. To the very theme of the fight against climate change, the US president considers the "scam", invented to curb the growth of industry.
