COP30: Send in YOUR climate change questions

What would you say if you got the chance to speak to politicians about climate change?

World leaders will gather at the world's biggest climate meeting - COP30 - in Brazil in November.

The BBC's Climate Editor, Justin Rowlatt will be in Brazil and will be speaking to some of them, including Ed Miliband, the UK Secretary of State for Energy and Climate Change.

If you have a question that you would like Justin to get answers to, let us know in the comments below.

What is COP30?

COP30, the 30th UN Climate Change Conference, will be held in Belém, Brazil, next to the Amazon Rainforest from 6 - 21 November 2025.

Leaders from around the world will discuss how to limit global warming, and how to help poorer countries deal with climate problems, and use cleaner energy instead of coal and oil that produce planet warming gasses.

But there are challenges too - making these kind of changes costs a lot of money.

There is still a large gap between current efforts and what scientists say is needed to avoid severe climate impacts.

"The idea of these big international meetings is to speed things up," says the BBC's Climate Editor Justin Rowlatt.

"Countries make promises to change the way they do things at these meetings, but they don't have to actually do it. It's just a promise.

"Often they say, 'Actually, it's harder than we thought, so we're not going to invest that money in wind turbines or shut down that coal mine.' Then the changes that would reduce emissions don't happen.

"But because climate change is a challenge we all need to solve together, we do need to keep on talking – because even though we haven't solved it yet, working together is still our best hope."
