That concludes a day of high drama in the White House and beyond.
It has seen Donald Trump pull out of the Paris agreement much to the delight of his supporters - and the horror of those who believe climate change is man-made.
His critics include the British and Canadian prime ministers, European leaders and his predecessor, Barack Obama.
However, the coal lobby and many Republicans have applauded him for a decision they believe will keep energy prices low and jobs high.
British prime minister Theresa May has told Donald Trump of her "disappointment" with his decision, Downing Street has said in a statement.
"The Paris agreement provides the right global framework for protecting the
prosperity and security of future generations, while keeping energy affordable
and secure for our citizens and businesses," May told Trump by phone.
America first, or America alone?
How does this latest move play into Donald Trump's vision of American leadership on the world stage, the BBC's Paul Adams asks.
Quote Message: A billionaire who is used to bending friend and foe alike to his will appears to struggle with anything more collaborative. But there are signs that his muscular approach, while popular among supporters at home, has already caused a shift in the tectonic plates of the global world order.

Canada 'deeply disappointed'
The US's friends across the border in Canada do not appear to be looking kindly on this latest announcement from the Trump administration.
Canadian prime minister Justin Trudeau took to Twitter to share his views:
His words echoed those of the Canadian environment minister Catherine McKenna, who had earlier told reporters:
Quote Message: Canada is deeply disappointed at the U.S. position. The Paris agreement is a good deal for Canada and it's a good deal for the world. No one country can stop action on climate change.

The new French president has reiterated his invitation to American scientists to move to France and continue their work, saying the US might be turning its back on the world, but his country would not be turning its back on America.
In a speech broadcast live on Facebook hours after Trump's announcement, Macron said there was "no plan B" when it came to climate change.
Trump, he added, has "made a mistake for future of our planet".
Coal lobby 'applauds' President Trump
The American Coalition for Clean Coal
Electricity (ACCCE) is delighted Donald Trump has pulled out of the Paris agreement - warning that staying in would have led to higher prices and less reliable energy.
Quote Message: We support President Trump’s decision to withdraw from the Paris agreement. The previous administration volunteered to meet one of the most stringent goals of any country in the world, while many other countries do far less to reduce their emissions. Meeting President Obama’s goal would have led to more regulations, higher energy prices, and dependence on less reliable energy sources." from Paul Bailey ACCCE President and CEO

It certainly seems that way...

A tale of two vice-presidents
What a difference a year makes.
In two tweets, the incumbent vice-president and his predecessor have shown off just how wide a gulf there is between their respective administrations:
President Trump’s
announcement in the Rose Garden felt like a campaign speech, just a little more
muted and minus the crowds.
To many of his supporters, leaving the Paris Accord
is another example of why Donald Trump is a strong president.
Trump voters I’ve
spoken to are delighted with today’s news.
"I’m celebrating, he’s saved jobs
and businesses," James in Virginia told me.
"It’s not worth the paper it’s
printed on," said Will.
"I think it was a bad deal in the first place," said
Cathy.
Marta in Texas said she wasn’t too familiar with the accord, but was "fed up" of environmental groups, which she views as "exclusive clubs".
That
sentiment is a view Trump supporters attach to other global organisations such
as the UN and Nato.
For them this is less about science, and more about sending
a signal to so-called global elites.
Many Republican voters lobbied against
climate deals way before Trump came on to the scene - arguing they hurt business.
By leaving the Paris Accord, President Trump has unravelled another thread of Barack
Obama's legacy, and that’s another reason many of his supporters are
celebrating.
'The world cannot wait  -  and neither will we'
The mayors of 61 cities around the US have joined together to reaffirm their commitment to the Paris agreement.
In an open letter, the mayors - representing 36 million people from Arkansas to Vermont - promised to "intensify efforts to meet each of our cities’ current climate goals, push for new action to meet the 1.5 degrees Celsius target, and work together to create a 21st century clean energy economy".
It concludes: "The world cannot wait  - and neither will we."

US states go it alone
The governors of Washington state, New York and California have announced the formation of the "United States Climate
Alliance, a coalition that will convene US states committed to upholding the
Paris Climate Agreement and taking aggressive action on climate change".
They said they are "committed to achieving the
US goal of reducing emissions 26-28% from 2005 levels and meeting or
exceeding the targets of the federal Clean Power Plan."
California Governor Jerry Brown told the BBC earlier this week he would now work with China on the issue.

Trump on climate change
Though the US president did not speak today about his views on climate change, his previous tweets hold nothing back. He has called it "a total con job".
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.
He was scathing about the Green Climate Fund, saying it would
cost billions of dollars - the US has pledged $3bn and paid around $1bn.
The overall tone and content of his speech clearly plays to his base but is
also a clear disavowal of multi-lateralism, especially on climate change and
will definitely push other countries more closely together on this issue.
Does Trump still believe climate change a hoax?
The president failed to mention in his speech whether he now accepts that man-made climate change - which he once derided as a hoax - is real.
Environment Protection Agency boss Scott Pruitt was asked on CNN after Mr Trump's speech what his boss's belief is now, but he would not say.

And her husband Jared Kushner? He was said to be in a meeting.
