Fight of supremacy am in charged-Trump

President Donald Trump on Tuesday signed an executive order curbing the federal government's enforcement of climate regulations, a move that represents a sharp reversal from his predecessor's position.

The Obama administration put in place a number of programs that attempted to address the impact of climate change, including rising sea levels and temperatures.

Trump said those actions harmed American businesses.

"With today's executive action, I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion and to cancel job-killing regulations," he said at an event marking the signing of the executive order.

Here's a look at six climate change policies affected by Trump's executive orders:

What Trump's executive order on climate change means for the world

Climate Action Plan

This 2013 plan rolled out by President Barack Obama focused on three areas: cutting carbon pollution in America, preparing infrastructure for the impact of climate change and making the United States a global leader on efforts to combat climate change.

It also called for reduction of greenhouse gases, a strategy on methane and a commitment to protect forests. Trump's executive order rescinded the plan.

Executive order on climate change. Obama instructed the federal government to prepare for the impact of climate change in a 2013 executive order.

It created a Council on Climate Preparedness and Resilience, charged with overseeing such a national effort. The council was made up of representatives from across the federal government to work with a task force of state, local and tribal leadership also created by Obama's order. On Tuesday, Trump revoked Obama's executive order.
