Tomorrow, the foreign secretary David Miliband will be here between 12-1pm to answer your questions on the crucial UN climate talks at Copenhagen in December. Miliband joins us as part of a new series of web chats with Guardian readers by government ministers on the Copenhagen summit.
This is your chance to quiz him on anything to do with the countdown to Copenhagen. As foreign secretary, brother of the energy and climate secretary Ed Miliband and owner of a CV that includes climate change experience as environment secretary, David Miliband is uniquely placed to talk about Copenhagen.
Want to know how hopeful he is that the UK can help governments reach an agreement to reduce emissions? What he thinks the main stumbling blocks are, such as delays to the US Waxman-Markey bill, wrangles between the developing and developed world on the historic responsibility for global warming and debates over how much money should be transferred from rich to poor countries adapting to climate change?
He has also signed up personally to the 10:10 climate change campaign that is being supported by the Guardian. It is encouraging people, companies and organisations to cut their carbon emissions by 10% by the end of 2010. Perhaps you'd like to know how he plans to cut his 10%.
Post your questions below and please note that we'll be treating anything that is not about environmental issues as off-topic.
• 8 September: David Miliband today announced a diplomatic tour of European countries to try to persuade them to put climate change at the top of their agenda. Speaking about the Copenhagen talks in December, a Foreign Office spokesperson said: "The deal is too important to be allowed to fail and the consequences of not having a deal are too great to consider. We hope the foreign secretary's diplomatic push will concentrate minds and draw attention to the wider implications of climate change."
