Image source, PA MediaClimate change is taking centre stage this evening as the first ever leaders' election debate on the issue gets under way on Channel 4 at 19:00 GMT.
This general election has been dubbed by some as "the climate election", but will it really play a defining role in which leader gets into No 10?

The argument around Boris Johnson's no-show for the climate change debate on Channel 4 is heating up.
The TV channel is displaying ice sculptures in place of the PM and of the Brexit Party's Nigel Farage - who also didn't accept the invitation - in the studio tonight.
Channel 4 editor Ben de Pear says, external former environment secretary Michael Gove and the prime minister's father, Stanley Johnson, both arrived to try to persuade producers to let them on the programme instead.
Elsewhere, Buzzfeed is reporting that the PM is threatening to review Channel 4's broadcasting licence after the ice sculpture stunt.
But that's something presenter Alex Thomson says he asked Mr Gove, external - and Mr Gove said he knew nothing about it.

It's all kicking off in High Peak in Derbyshire, says our political reporter Chris Doidge.
Labour candidate Ruth George says her solicitors have referred her Conservative opponent, Robert Largan, to the Director for Public Prosecutions.
In return, Robert Largan says he's referred her to the police.
They're accusing each other of breaching s106 Representation of the People Act.
Ruth George says he's made claims about her being anti-Semitic, which she denies.
Robert Largan says she has accused him of committing a criminal offence, which he denies.
Image source, Getty ImagesAhead of the climate change debate on Channel 4 this evening, Plaid Cymru leader Adam Price says Wales could be "a global leader" in tackling the issue.
He says the country's "wealth of natural resources" puts it in "an optimum position" to lead the fight.
"Climate change is the defining challenge of our times, and if we're to arrest its halt, politicians need to act urgently and decisively," he says.
Mr Price's party's manifesto, external pledges include making Wales a carbon-free and single-use plastic-free country by 2030 as part of a £20bn "green jobs revolution".
"There's no denying that the scale of the challenge is large, but it is by no means insurmountable. With the necessary level of political will, we can save our planet," he adds.
"For a sustainable Wales, which takes the climate emergency seriously, and of which we can proud to pass on to our children and grandchildren, it's us."
For anyone confused by that last sentence, "it's us" is the title for Plaid's manifesto.
Here's a first look at the ice sculptures that will sit in place of Boris Johnson and Nigel Farage after they turned down an invitation to take part in Channel 4's climate change debate at 19:00.
Leaders of the other major political parties will be on the programme.

Image source, Getty ImagesWith two weeks to go, the parties are assessing their campaign strategies.
Here's the analysis from our correspondents on the campaign trail.
Image source, ReutersActor Hugh Grant has added his voice into the election debate, urging voters in seats where high-profile Conservatives are standing to unite against them.
In a series of tweets, he picked out constituencies including Uxbridge where PM Boris Johnson is standing, Esher and Walton where Dominic Raab is standing and Chelsea and Fulham where Greg Hands is up for re-election.
Yesterday he also tweeted that he had "never been [a] supporter of any one party" but was going to try and support some "pro 2nd ref" people.
Neale Hanvey will still appear on the ballot paper, but the SNP has pulled support from his campaign
The SNP has dropped its candidate for a key target seat after allegations of anti-Semitism were made against him.
Neale Hanvey is contesting the Kirkcaldy and Cowdenbeath constituency, where Labour has a majority of 0.6%.
However, the SNP has now withdrawn all support for the former councillor's candidacy, saying he had been suspended pending disciplinary action.
Business convener Kirsten Oswald said: "Anti-Semitism has no place in Scotland, and no place in the SNP."
Boris Johnson and Nigel Farage - who have both not decided to join Channel 4's leaders debate tonight - will be replaced by two ice sculptures, the broadcaster has said.
Tonight, Channel 4 News are hosting an hour-long Emergency On Planet Earth debate, focusing on climate change, with the party leaders.
Ben de Pear, editor of Channel 4 News, said: "These two ice sculptures represent the emergency on planet earth, not in any human form but are a visual metaphor for the Conservative and Brexit parties after their leaders declined our repeated invitations to attend tonight's vital climate debate."

Labour’s John McDonnell says his party has been “conservative with a small ‘c’” with the amount it can raise through taxes.
Earlier, the Institute for Fiscal Studies said it was“highly likely” that Labour would need to raise taxes beyond what it is promising to pay for its proposed £80bn a year in extra spending.
The shadow chancellor said: “They’re saying we’re too ambitious, I’m proud of that. The issue is, is it deliverable? We believe it is.”
He also says the amounts raised through taxation in Labour’s “grey book” are at the lower end of what was possible: “We’ve not taken what is the maximum that can be raised, far from it, we’ve usually halved that amount."
On the latest polls, he suggests Labour will continue to gain ground: “The polls in terms of levels of support don’t seem to be reflecting what we’re hearing on the doorstep.
"We feel we’ve got a sizeable amount of support that’s building all time and you’ll see that, I think, in the polls in the last two weeks.”
Asked whether predictions of a Conservative majority could work in Labour’s favour, he said, “Sometimes being the underdog is helpful.
"The feeling we get on the doorstep is that people are worried about five years of a Boris Johnson… so yes, sometimes the polls do play into our hands in that respect.”
Labour leader Jeremy Corbyn is "not a pacifist" and would defend the UK "whatever it takes", shadow defence secretary Nia Griffith has said.
Speaking at a defence debate organised by the Royal United Services Institute, Ms Griffith said: "Look, Jeremy Corbyn takes the defence and security of this country extremely seriously and will do whatever it takes to defend this country.
"The point is he is a very thoughtful leader who wants to see the full facts and wants to have the full information in any decision making that he makes, and so he will take a very measured approach and as would all experts in the field."
She added: "But at the end of the day, if it is a threat to security - as I have said and he has repeated on many occasions - he will do whatever it takes, and that is an absolute commitment."

Our correspondent Ben Wright moves on after failing to get an answer from the PM about whether or not he'll allow Andrew Neil to interview him.
In response to a YouGov poll suggesting the Tories could secure a big majority on polling day, Mr Johnson says: "I think actually that it's very close - I think it's a very tight race indeed."
He then takes the opportunity to take a dig at some of Labour's policies and warn against Jeremy Corbyn moving into Downing Street.
You can read about the caveats to that poll in the analysis polling expert Sir John Curtice shared with us this morning.
PM refuses to commit to Andrew Neil interview
Our correspondent Ben Wright kicks off a short interview with the prime minister, on a farm in Exeter, by asking if he'll promise to appear on Andrew Neil show on the BBC.
All the other major party leaders have agreed to being interviewed by Neil - who gave Jeremy Corbyn a grilling when he appeared on the show on Monday evening.
Boris Johnson refuses to answer.
He says conversations are ongoing about "all sorts of interrogations and inquisitions", adding: "'I'm very happy to be interviewed by anybody."
The BBC's economics editor, Faisal Islam, has been looking at the independent Institute for Fiscal Studies' analysis.
In particular, he's cast his eye over what the IFS thinks will be the consequences if the Conservatives carry out their manifesto pledge not to extend the Brexit transition period included in the PM's Brexit deal beyond 2020, even if a trade deal has not been agreed.

Our correspondent adds: "The IFS suggest Labour, even with its plans for big expansion would see the national debt up around 75-76%/GDP - but the Conservatives not extending the Brexit deadline and choosing WTO would see debt at 80%/GDP - 73% with a deal.
"Lib Dems meanwhile down near 70%.
"Conservatives argue this is not like with like, and that Labour's economic plans in the round will hit growth and lead to much higher deficits than this."
Image source, Getty ImagesBBC environment analyst Roger Harrabin says this has been by far the greenest campaign in UK election history.
After 30 years of reporting on this issue, he thinks that some of the major parties have policies that match up to the scale of the challenge. Read more of his analysis.
