Despite the certainty that a significant proportion of global climate change is being driven by man-made factors, sceptics continue to at times dominate debate, derailing the impetus needed to begin to address how to deal with it.
Arguably mainstream media is finally changing its attitude toward the nay-sayers, with less space devoted to their rants and more to analysis of the real problems, but worryingly public perception of the issue has been severely damaged.
Thanks partly to the efforts of tragi-comic fools like the so-called "Lord Monckton" - widely reputed to be comic Sasha Baron Cohen in disguise - it's estimated only about 42 per cent of Americans, and a similar number of Britons, believe in human-induced climate change. That's a distinct drop, more than 10 per cent, from a decade ago.
That's particularly significant because, just when the world's leaders appear to be waking up to the need for genuine redress, their electorates are signalling a lack of support for doing so. Resulting in a thorny political conundrum.
Thankfully many leaders, from all parts of the political spectrum, now appear willing to at least carefully discount public opinion in favour of the search for solutions. In this, they are strongly aided, or should that be prompted, by the UN's IPCC process and the almost-unanimous voice of the world's scientific community.
