David Bellamy accurately described global warming as 'poppycock', that is an anglicised version of the Dutch word for 'cow pat', i.e. a genteel way of saying BS. This heresy against the new religion got him removed from television. This might explain why Sir David Attenborough is such an enthusiastic protagonist of this nonsense: He has a reputation to maintain, which will not withstand the onslaught of vindictive lies that the perpetrators of this rubbish hurl at 'deniers'.
