Pick of the week
Underfed polar bears, bleached corals, disappearing toads - they are all symptoms of that global malady, rapid climate change. In Wednesday's powerful but depressing Warnings from the Wild (9.30 BBC2) Julian Pettifer offers examples of what happens when, in the words of Stanford's Stephen Schneider, "we use the atmosphere as a free sewer to dump our waste". Global warming crops up in C4's Deluge (Monday 8.00) and R4's Nature (Monday, 9.00), about floods in Australia.

Today, The Rise and Fall of Mo Mowlam (7.00), and New Labour on Trial (7.30). And on Sunday, Tony's New Boy Network (8.00), in which Nick Cohen lifts a few stones and shines a torch on the cronies and spin doctors beneath.
