Climate change: Trump's repeal of climate change regulations will be felt far beyond his presidency



But repealing regulations designed to curb global warming is one of the clearest ways he has worked to erase the cornerstone of President Barack Obama's legacy.

Regardless of what happens in the 2020 presidential election, critics say Trump has already cemented the environmental legacy that will be felt by generations to come.

"Concludes in persistent, irreversible environmental damage through its irresponsible environment policies, including its efforts to block progress in climate change," said Dr. Michael E. Mann, an associate professor of atmospheric science at Penn State University and director of the Pen State Earth Center for Earth Systems. "Once we get beyond the key points ̵

Here's a look at some of Trump's most consistent climate policy changes: [19659003]

Losing fuel by economic standards

Last year, the New York Times reported that the Trump administration is seeking to ease fuel efficiency and greenhouse gas emissions, which will cancel one of Obama's signature climate initiatives.
If the proposed change actually changes, it can have profound consequences for the planet: Transportation emits more greenhouse gases than any other sector of the US economy, according to the Environmental Protection Agency.
But California and several other states have filed a motion to block the change, and there are signs that even some automakers are not aboard Trump's backlash.

Replacing the Clean Power Plan

In the wake of electricity services and the fight against the coal industry, Trump's move to replace the Obama Clean Power Plan (CPP) can have serious effects on human health and health. the planet.

CPP has set flexible limits on carbon dioxide emissions from power plants and, according to Obama's EPA analysis, will reduce CO2 emissions from electricity generators by 32 percent compared to 2005 levels by 2030.

Trump's replacement of CPP is called the Clean Power Rule and allows states to set their own emissions standards for coal-fired power plants. Earlier this year, EPA Administrator Andrew Andrew Wheeler announced the plan, saying it gave energy companies "the necessary regulatory certainty to continue to reduce emissions and provide affordable and reliable energy for all Americans."

But the new rule can cost the lives of Americans. According to the EPA's own analysis, Trump's rule could lead to 1,400 premature deaths by 2030 than with the CPP. Many states and cities also want to block the entry into force of new regulations.

Opening public lands and offshore waters to oil and gas drilling

Many scientists have warned that the conservation of fossil fuels in the earth is critical to dealing with the climate crisis. But the Trump administration has moved the US in the opposite direction, finding huge stretches of land and water in the sea to oil and gas drilling.

In 2017, the administration shrunk two Utah National Monuments — the Grand Escalation of Escalante and the Bear Ears — by 51% and 85%, respectively. The moves took over land twice as large as Rhode Island from protected status and were part of the largest public lands decline in US history, according to a study published in the journal Science. The changes open areas removed from national monuments for oil and gas development, but both solutions face challenges before the courts.

The administration also insists on opening the Arctic National Wildlife Refuge of Alaska for oil and gas exploration, as well as shores along the East and Pacific Coast and Arctic coast.

"The pipeline projects potentially block the long-term extraction of natural gas and oil and therefore have a very long legacy that will go beyond the next administration," says Mann.

Getting out of the Paris climate agreement

Trump's decision to withdraw the United States from the landmark Paris agreement in 2017, agreed by almost every country in the world, was a major blow to the global response to the climate crisis.
The decision sent a message to the rest of the world that the US – which could legally leave the agreement as early as 2020 – would not lead the global fight against climate change. And studies show that the decision has global implications: a report last year found that Trump's decision makes it easier for other countries to renew in terms of their climate commitments.

Limiting Methane Emissions Limits

Just last week, Trump's EPA announced that it would no longer require oil and gas companies to install monitors that detect methane leaks from new wells, tanks and pipelines.
  In 2012, a striking platform near Waynesburg, P. was shown.

At a time when the United States has become the largest producer of natural gas and oil in the world, this move is significant because of the potential of methane capabilities to capture heat. Although gas does not last as long as CO2 in the atmosphere, one tonne of methane has 84 to 87 times greater global warming potential than the same amount of CO2 over a 20-year period.

Delaying ratification of a hydrofluorocarbon treaty

Another key global agreement to curb the planet's warming gas came into force earlier this year, but Trump has yet to send it to the Senate to ratify it.
The treaty is called the Kigali Amendment and deals with a little known but highly potent class of greenhouse gases called hydrofluorocarbons (HFCs) used in refrigerators and air conditioners. Gases are sometimes called "super greenhouse gases" because of their ability to capture huge amounts of heat into the atmosphere – they have over 1000 times the potential for carbon dioxide to warm up.
Climate Change Organization Project Drawdown found that gradually eliminating these chemicals would be the most influential solution to stopping global warming – more than consuming less meat, driving electric cars, or switching to renewable energy.
