Global warming sceptics in the UK have gathered to mark what they've dubbed 'Climate Fools Day'. On this date two years ago, snow fell in London as the British Parliament was debating a bill to tackle global warming. It was the first such early snowfall for over eighty years. Activists claimed the ironic coincidence was just more proof that the bill is a waste of billions of tax-payers' pounds. One of those doubting the reality of climate change is Reverend Philip Foster, who joins us now live from London.
