Given that I’ve linked to two or three of the others, I think it right that I direct you here, to the final part of Frozen Planet. It is a vivid illustration of climate change, and how global warming is increasingly affecting the planet. In fact it is unusual for an Attenborough program in that it argues a point – that global warming is a real phenomenon – rather than being purely descriptive. To that end, it is very persuasive indeed, and I’d urge anyone who still somehow doubts the reality of global warming to watch this programme

However, the part which touched me the most, must have been the piece after the show itself had finished*, where sir David speaks the lyrics to ”What A wonderful World”. He has had a remarkable career, and I can’t help suspecting his appearance tonight (remarkably in tonights programme he stood in the Antarctic at the age of ninety and did several pieces to camera – I’m in awe of the guy) may be his last. Thus, this final part acted as his swan song, a summation of his life on air, and perhaps a farewell. I therefore found t very touching indeed; it brought a lump to my throat, and I suspect it will be something I’ll watch again and again. Thanks, sir David.

*Sadly, it is therefore not on the Iplayer recording
