The question that has to be continuously asked – is the science on climate change sound enough to justify Ireland facing into an enormous ongoing diminution of our agricultural potential?

What caused me to pause in my certainty was a lecture given last week in Dublin by the retired professor of atmospheric sciences at the Massachusetts Institute of Technology (MIT), Richard Lindzen. MIT is one of the leading scientific institutes in the world and if scientists who have reached that stage of achievement in their career are making serious points, then in my view we have a duty to at least listen and try and assess the arguments.
