Climate Change and Sustainable Energy Bill

I do not know whether my hon. Friend will come to this at some stage in his speech, to which I shall listen with fascination, but will he talk about scenarios and temperature ranges? Various things came out very clearly in their lordships’ excellent report. For example, in paragraph 72, they say:"““We received a significant amount of evidence on the realism of . . . emissions scenarios, and doubts were raised, particularly about the high emissions scenarios.””" That all sounds very technical and obscure. Of course, for understandable reasons, the Bill’s promoter did not want to detain the House for too long on the underlying principles of climate change, but will my hon. Friend consider any of that during his remarks?
