Tomorrow, the three politicians who are fighting to be the next climate minister will lock horns in the Guardian's climate and energy election debate.
While tickets for the event in London are sold out, you can still put your question for the speakers - Ed Miliband for Labour, Greg Clark for the Conservatives and Simon Hughes for the Liberal Democrats - by posting it below. As Andy Atkins of Friends of the Earth argues today, all three major parties recognise the importance of acting on climate change, but they still desperately need "a seismic shift in political thinking."
You can also hear the trio's answers by listening to our live audio stream and following our live Twitter coverage tomorrow night - check back at environmentguardian.co.uk at 7pm on 21 April or just follow us on @guardianeco.
