It is rather good to have on the record the noble Viscount’s opinion that climate change has been happening, and I have to say to him that it is a process that it is continuing.
I am the chairman of the Environment Agency in England. We are already seeing increasingly erratic and extreme patterns of weather here in the UK. Last year, in 2012, the first three months saw us in near drought. That was followed by 11 serious flooding events during the summer and autumn. In March, the River South Tyne was flowing at 28% of its average flow for that time of year; by June, two months later, it was running at 408% of its average flow for that time of year. I cannot say that the erratic weather patterns that we are now increasingly seeing in the UK are directly attributable to climate change, but I can say that this is precisely the sort of effect that climate science tells us we are going to see an awful lot more of over coming decades unless we do something serious about decarbonisation.
It looks as if we are heading for at least a 2 degree rise in global temperatures, and probably more, and the consequences of that for flooding, water supplies, agriculture, movement of population and human health are incalculable. Therefore, it is important for all of us to do what we can to take carbon out of our activities. Decarbonising energy production over the next 20 years is not just a “nice to have”, a luxury, or something to be thrown aside the first moment that some flak appears; it is essential if we are going to have anything remotely resembling a coherent and sustainable energy policy in the future.
A decarbonisation target is not just important because of climate change; it is essential in order to give confidence and certainty to the burgeoning renewables and energy efficiency industries. Putting clear targets in place will stimulate innovation and enable long-term investment and planning to take place. Energy, perhaps more than any other field of government policy, needs long-term thinking and, if at all possible, cross-party thinking, too. We have to put the parameters in place and make the target clear but achievable, then the ideas, investment, work and economic benefits will flow. The amendment of my noble friend Lord Oxburgh seeks to do precisely these things and I fully support it.
