What impact will the US pull-out from the Paris Agreement have on climate change?

US withdrawal from the Paris agreement could have some serious effects on the world and on the goals of this agreement as following.

Paris agreement was signed by all the countries of the world, developed and developing. This fact gives the agreement a touch of universality. Withdrawal by US damages this universal consent and makes it less effective.

US emits 15% of carbon globally. The withdrawal may affect the global target of 2C. In addition to this US was one of the developed countries, which could provide funds to developing countries in order to cut down their carbon production. But with the withdrawal from the Paris accord, the developing countries may suffer from the lack of funds.

However, after US pulled out itself from the Paris accord, EU and china has assured the world about their ongoing struggles and support to achieve the targets.
