Tackling global warming: Quiz Margot Wallstrom

Climate change is back on the agenda, following warnings from a UN panel that the Earth is warming up much faster than many scientists had previously predicted.

Next week, politicians from more than 150 countries meet in Bonn, to try to salvage the Kyoto Protocol.

Last year's attempt to agree a way forward in The Hague collapsed in acrimony, with the British and French environment ministers trading insults.

Since then, the US has pulled out of the treaty altogether. Strenuous efforts will be made in Bonn to bring America back into the fold.

Japan has said it's unwilling to go ahead without the US, but the European Union wants to proceed with the agreement whether the Americans are on board or not.

Will the latest scientific evidence bring a greater sense of urgency to the talks? Can the industrialised countries overcome their differences and work together to counter global warming? Can any agreement be reached in Bonn?

The EU's Environment Commissioner, Margot Wallstrom, will be joining us for a live forum on Wednesday. You can e-mail your questions to her using the form below.
