[ti:US Withdraws from Paris Agreement Aiming to Limit Climate Change]
[00:00.04]The United States officially withdrew from the Paris Agreement
[00:05.48]to fight climate change on Wednesday.
[00:08.44]Leaders from around the world approved the agreement
[00:12.80]in 2015 at a conference in the French capital.
[00:18.88]For more than two years, American President Donald Trump
[00:23.40]talked about withdrawing from the treaty.
[00:27.08]Last year, the Trump administration announced the U.S. decision to withdraw.
[00:33.96]However, the results of the presidential election could decide for how long.
[00:41.28]Trump's main opponent in the vote, former Vice President Joe Biden,
[00:46.60]has promised to rejoin the climate agreement if he is elected.
[00:51.92]More than 180 countries remain committed to the 2015 Paris accord.
[00:59.20]The agreement aims to limit the increase in average temperatures worldwide
[01:04.08]to "well below" 2 degrees Celsius,
[01:07.80]and ideally no more than 1.5 degrees Celsius.
[01:13.80]Those increases are compared to temperature levels
[01:17.12]before Europe's Industrial Revolution.
[01:20.72]Scientists say that any temperature increase greater than 2 degrees Celsius
[01:26.60]could have a disastrous effect on large parts of the world.
[01:30.40]Such an increase, they say, could raise sea levels,
[01:35.16]fuel powerful storms and worsen droughts and floods.
[01:41.60]The Paris accord requires countries to set their own targets
[01:45.88]for cutting production of carbon dioxide
[01:49.36]and other gases linked to rising temperatures.
[01:53.76]The only legal requirement is that national governments
[01:57.52]must truthfully report on their efforts.
[02:01.68]The United States is the world's second biggest
[02:04.52]producer of heat-trapping gases, after China.
[02:08.64]In recent weeks, China, Japan and South Korea
[02:13.08]have joined the European Union (EU) and other countries
[02:16.72]in setting national targets to stop
[02:19.36]pumping more greenhouse gases into the atmosphere.
[02:24.12]Biden, the Democratic Party's candidate for president,
[02:27.68]has said he supports calls for the United States to return to the Paris accord.
[02:34.40]On Wednesday, Germany's government said it was "highly regrettable"
[02:38.84]that the United States had left the accord.
[02:41.92]"It's all the more important that Europe,
[02:44.84]the EU and Germany lead by example,"
[02:48.28]government spokesman Paul Seibert said.
[02:51.80]While the Trump administration has rejected
[02:54.96]federal measures to cut greenhouse gases,
[02:57.80]Seibert noted that U.S. states, cities
[03:01.52]and businesses have pushed ahead with their own efforts.
