President Donald Trump has announced that the US is withdrawing from the 2015 Paris climate agreement.
He said moves to negotiate a new "fair" deal that would not disadvantage US businesses and workers would begin.
Mr Trump said during last year's presidential election campaign that he would take the step to help his country's oil and coal industries.
Opponents say withdrawing from the accord is an abdication of US leadership on a key global challenge.
The Paris agreement commits the US and 187 other countries to keeping global temperatures rises "well below" 2C (3.6F) and "endeavour to limit" them even more, to 1.5C. Only Syria and Nicaragua did not sign up to the deal.
What did Trump say?
Speaking in the White House Rose Garden, Mr Trump characterised the Paris agreement as a deal that aimed to hobble, disadvantage and impoverish the US.
He claimed the agreement would cost the US $3tn in lost GDP and 6.5 million jobs - while rival economies like China and India were treated more favourably.
"In order to fulfil my solemn duty to protect America and its citizens, the United States will withdraw from the Paris climate accord... but begin negotiations to re-enter either the Paris accord or a really entirely new transaction on terms that are fair to the United States," he said.
The speech contained several rhetorical flourishes reminiscent of his campaign speeches.
"We don't want other leaders and other countries laughing at us any more - and they won't be," he said.
"I was elected to represent the citizens of Pittsburgh, not Paris. I promised I would exit or re-negotiate any deal which fails to serve America's interests. Many trade deals will soon be under re-negotiation."
The BBC's Rajini Vaidyanathan in Washington says the move will be welcomed by many Trump supporters, as for them this is less about science - and more about sending a signal to so-called global elites.
Analysts say the US withdrawal from the Paris agreement will make it more difficult for the world to reach the goals that it set for itself in the Paris agreement.
The US contributes about 15% of global emissions of carbon, but it is also a significant source of finance and technology for developing countries in their efforts to fight rising temperatures.
Mr Trump did not give a timescale for US withdrawal, but White House sources had earlier suggested it could take up to four years.
Former US President Barack Obama, who agreed to the Paris deal, immediately criticised the move, accusing the Trump administration of "rejecting the future".
Republican congressional leaders and the US coal industry backed the move, with Senate Majority Leader Mitch McConnell supporting Mr Trump "for dealing yet another significant blow to the Obama administration's assault on domestic energy production and jobs".
Senate Democratic leader Chuck Schumer called the decision "one of the worst policy moves made in the 21st Century because of the huge damage to our economy, our environment and our geopolitical standing".
The leaders of France, Germany and Italy issued a joint statement rejecting a renegotiation of the agreement.
"We deem the momentum generated in Paris in December 2015 irreversible and we firmly believe that the Paris agreement cannot be renegotiated, since it is a vital instrument for our planet, societies and economies," it said.
Canada was "deeply disappointed" by President Trump's decision, Environment Minister Catherine McKenna told reporters.
This was echoed by UK Prime Minister Theresa May, who expressed her disappointment and told Mr Trump in a phone call that the deal protects the "prosperity and security of future generations".
Leaders of the Nordic nations - Sweden, Finland, Denmark, Norway, and Iceland - also condemned the move.
A United Nations spokeswoman said it was a "major disappointment for global efforts to reduce greenhouse gas emissions and promote global security".
Small island nations whose existence is threatened by rising sea levels were critical of the move. The President of the Marshall Islands, Hilda Heine, said it was "highly concerning for those of us that live on the frontline of climate change".
Tech entrepreneur Elon Musk confirmed that he was leaving his role as an adviser to the Trump administration in protest.
"Am departing presidential councils. Climate change is real. Leaving Paris is not good for America or the world," he tweeted.
'Worse than expected'
By BBC environment correspondent Matt McGrath
President Trump's statement is a very clear repudiation of the Paris agreement and international efforts to fund climate mitigation and adaptation in poorer countries.
In many ways it is far worse than many had expected. He sees it as a clear job killer, as an economy strangler and a desperately unfair stitch-up by other countries wanting to take economic advantage of the US.
He spoke of being open to re-negotiating the deal or trying to build a new agreement - but the idea of "re-negotiation" is an unlikely scenario.
The scale of his opposition, seeing the deal as "a massive redistribution of US wealth to other countries" is a clear indication that he has fully bought into an economic nationalist and climate denier perspective.
The question of unfairness cropped up again and again, how the world's worst polluters, China and India, had "no meaningful obligations" placed on them by the deal.
The overall tone and content of his speech clearly plays to his base but is also a clear disavowal of multilateralism, especially on climate change, and will definitely push other countries more closely together on this issue.
What was agreed in Paris?
Climate change, or global warming, refers to the damaging effect of gases, or emissions, released from industry and agriculture on the atmosphere.
The Paris accord is meant to limit the global rise in temperature attributed to emissions.
Countries agreed to:
Keep global temperatures "well below" the level of 2C (3.6F) above pre-industrial times and "endeavour to limit" them even more, to 1.5C
Limit the amount of greenhouse gases emitted by human activity to the same levels that trees, soil and oceans can absorb naturally, beginning at some point between 2050 and 2100
Review each country's contribution to cutting emissions every five years so they scale up to the challenge
Enable rich countries to help poorer nations by providing "climate finance" to adapt to climate change and switch to renewable energy

The 2015 Paris Agreement was the first pact to commit all nations to limiting global warming caused by emissions from burning coal, oil and gas
Paris (AFP) - The 2015 Paris Agreement, which the United States will quit according to President Donald Trump's announcement on Thursday, is the first pact to commit all nations to limiting global warming caused by emissions from burning coal, oil and gas.
Key facts about the pact:
- The climate club -
A total of 196 nations, including the Palestinian authorities, have endorsed the agreement and 147 have officially ratified it.
The accord entered into force in record time on November 4, 2016, when it crossed the threshold of 55 ratifying parties representing 55 percent of global greenhouse gas emissions.
China, the world's number one greenhouse gas polluter and Europe, number three after the US in second place, recommitted to the Paris Agreement Thursday.
The biggest polluter not to have ratified the deal is Russia (number five after India).
- Rules of engagement -
The agreement makes provision for parties to quit, but notice can be given only three years after its entry into force.
Withdrawal would take effect a year after that. But on Thursday, Trump said the US would "cease all implementation" of the accord "as of today."
A country can also withdraw from the 1992 UN Framework Convention on Climate Change (UNFCCC) under whose auspices the deal was negotiated. Withdrawal would take effect a year after notification, which can be given at any moment.
- The goal -
Nations agreed to hold global warming to "well below" two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, and to strive for a lower limit of 1.5 degrees.
Experts say even the two-degree ceiling is a tall order, requiring an immediate and deep reduction in planet-warming emissions from fossil fuels -- an industry with major influence in Washington.
Signatories to the deal will aim for emissions to peak "as soon as possible". The UN's climate science panel recommends a 40-70-percent cut by 2050 from 2010 levels.
Based on voluntary pledges by countries so far, the planet is on track for warming of about three degrees, many scientists say -- a recipe for catastrophic floods, storms, drought and sea-level rise.
- Tracking progress -
In 2018, and every five years thereafter, countries will take stock of the overall impact of their efforts to rein in global warming.
Some nations, including the United States, set emissions-curbing targets for 2025, others for 2030. Both categories must be updated every five years starting 2020.
- Financing -
Rich countries are expected to provide funding to help developing countries make the costly shift to cleaner energy sources and to shore up defences against the impacts of climate change.
They have committed $100 billion (89 billion euros) per year by 2020.
But Trump on Thursday said that the United States, which pledged $3 billion towards the Green Climate Fund of which it delivered $1 billion under Obama, would not implement financial commitments or national emissions-curbing measures pledged under the pact.
