Climate change has turned into "the issue" here in Davos. For me, the jury is still out on who is setting the agenda around here -- is it WEF's list of sub-themes in the extremely detailed Davos program, or is it the media obsession about chosen topics which is creating the buzz? It's probably chicken and egg and I'm not sure it much matters as long as the delegates have something to talk about and the journos have something to report. The lack of snow at the beginning of the week gave us the perfect excuse to explain that climate change would be grabbing much of the attention. As if we had a clear example on our very own doorstep. But let me tell you, the snow has well and truly arrived and temperatures are dropping fast.

One of the low points last year, when I was producing the evening shows, was the question from London about the "smoke" coming out of Charles and Becky's mouths. "It's condensation" I explained wearily. "Can we get rid of it?" they asked. "Well here's the thing ... it's minus 25 degrees, I can barely speak and neither can the anchors, I've forgotten what it's like to be able to feel my hands and feet and our heaters have broken down. So er ... the condensation right now is the least of my worries and frankly, out of my control." Those memories came flooding back today as I was back at the same liveshot position (raised on a platform this time and thus, comfortingly named "the gallows,") freezing my socks off and wondering when I could head back in for a much needed cup of tea. It's very glamorous, this TV stuff. I look like a Michelin Man in a million layers, my extremeties are blue from cold and all I can dream of is a hot drink and hot bath. Not likely while we've airtime to fill --- dream on!
