The prime minister told the children, who visited Downing Street for School Report News Day, that the government was doing all it could to tackle climate change.

Other political leaders, including the Conservatives' David Cameron and the Liberal Democrats' Menzies Campbell were also interviewed, as were pop star Lil' Chris and John Challis, who plays Boycie in Only Fools and Horses.
Working to a strict deadline, students are completing their reports by 1400 GMT and publishing them on their school websites by 1600 on 22 March.
As well as questioning VIPs, the thousands of 12- and 13-year-olds taking part also reported on the issues that affect them on a daily basis, including bullying, crime and transport.

Tough questions
BBC journalists are reporting on what schools are doing. News 24 is in Birmingham, BBC Breakfast is in Newcastle, Radio Five Live is in Leeds, Radio Four is in Cheshire and Newsround is in Hampshire.

A day-long programme - School Report LIVE - is being broadcast on the School Report website from 0900 GMT.
Among the tough questions facing Sir Menzies Campbell, 65, was: "Are you too old for the job?"
Presented by Ellie Crisell, from BBC News 24 and Newsround, it will feature live updates from a cluster of schools in Manchester.
Gang culture
It will also include TV reports from students around the country about the news stories that matter to them.
For those pupils without big interviews lined-up, popular topics included government plans to raise the school leaving age to 18, healthy eating, the row over size-zero models and crime and gang culture.

Ellie Crisell said School Report was an opportunity for the BBC
Ellie said: "It is a fantastic opportunity, giving students a real insight into how a newsroom operates.
Other schools looked at the 200th anniversary of the abolition of the slavery act.
"The fact that their finished news programmes will be accessible from the BBC website is a real incentive."
Lois, 13, from Eltham Hill Technology College for Girls in London, reported how she is herself descended from slaves.
She added: "It also gives the BBC an insight into how 12 and 13-year-olds view the world around them, what kind of stories are important to them, and what they want from news.
A pupil at Chatham South School in Kent who helped secure half-price bus fares for pupils made the front page of its School Report website.
"It's a great opportunity for the BBC to find out what fresh new talent is out there.
And students at Lewisham City Learning Centre hosted a live weather forecast and predicted a chilly end to the week.
"Some of these students could be inspired to move into journalism after they've finished education, and we may end up benefiting from their expertise down the line."
