Energy and Climate Change

I thank all hon. Members for their thoughtful and measured contributions, including that wonderful description of the Planning Inspectorate's recent decision. Many hon. Members will have some sympathy with the views expressed there. I must confess a personal interest. I am the son of a climatologist, so I spent many of my formative years learning about the natural cycles of climate, visiting sites such as medieval vineyards around Tewkesbury and so forth as friends were heading off to Torremolinos. Today, however, our focus is on man's impact on climate and how we respond to it. I shall deal first with the contribution from the hon. Member for Brighton, Pavilion (Caroline Lucas). The hon. Lady's case is that the 2% target—limiting the increase of global average temperatures to 2% above pre-industrial levels—is not ambitious enough and has potentially devastating consequences. I share and the Government share her absolute concern about the need to take effective and decisive action to deal with what is an enormous challenge globally, and we do not dismiss it at all. The target of less than 2%, however, is likely to be at the very edge of what is possible in terms of the technological and economic implications. It also involves radical lifestyle changes, and dealing with that globally and in democracies is often very difficult. Achieving the 2% target globally will itself be immensely challenging. On the current trajectory, as the hon. Lady rightly said, we are looking at a 3.5° C to 4° C rise in temperature, the consequences of which certainly would be devastating, and if anything the gap is widening.
