Join the debate on What's up with the Weather?
Just ahead of the release of the final report from the inquiry into the climate change email scandal - now known of course as 'Climategate' - Panorama enters the polarised world of climate science in our latest film, What's up with the Weather?
As global warming scepticism grows, Panorama goes back to basics and asks what we really know about our climate and how it will affect us.
As producer Mike Rudin puts it, "to some, it's a massive conspiracy to con the public. To others, it's the greatest threat to the future of our world."
Panorama reporter Tom Heap speaks to some of the world's leading scientists on both sides of the argument, to find out what they can agree on and uncovers some surprising results.
