Madam, - Andy Barclay (March 4th) incorrectly implies that lower temperatures in the upper atmosphere are at variance with the global warming of climate change.
Actually, it is one of the predictions of the science of climate change that temperatures in the stratosphere will decrease as concentrations of greenhouse gases rise. This is because these gases retain heat in the lower parts of the atmosphere. - Yours, etc,
