The 40th anniversary of the moon landings has inevitably prompted comparison with the current effort to preserve Planet Earth from global warming. As Ed Miliband has noted both missions involve combining political will with examples of technological leapfrog.  

One sobering contrast, however, is that although serious resources are now being deployed in green investments, the central co-ordination of the effort to reduce greenhouse gas emissions and overcome climate change is still pitifully resourced compared to what was spent on Houston.   The world lacks an ‘e-mission control’.

It’s been a good month for climate-sceptics. Following the failure of the Copenhagen summit to deliver a global treaty, they have revelled in the discomfiture of the Intergovernmental Panel on Climate Change as it admitted it was wrong to say that the Himalayan glaciers could disappear by 2035.  Critics have seized on this admission, using it to call the entire credibility of the IPCC and the science of climate change into question. 

There is a lesson in this for those who think global warming is worth worrying about. And counter-intuitively perhaps, I would suggest that the lesson is not to try to prove global warming is a fact and simply show that it is a significant risk – because that should be cause enough for action.
