Climate change is a serious challenge for every single one of us except, it seems, George Bush. Jyoti Banerjee checks out his own carbon footprint while assessing the environment’s impact on growth.
Nick Stern’s review of the economic consequences of climate change (commissioned by the UK Treasury) is nearly upon us. He is expected to announce that climate change will result in a 20% fall in global output, the sort of scale of negative impact on growth and development we might expect from a world war. Read Robert Peston's review of the Stern Review here.
In macro-economic terms, the plunging economic performance comes from a mix of factors:
dealing with lower agricultural and food output; the increased depreciation of capital due to its redeployment on things like sea defences as well as the greater pace of technological obsolescence (we will be throwing away our heating systems and installing air-conditioning, for example); and the adverse impact of climate change on people’s skills and development.
There is no doubt that climate change has moved into a higher gear. Many environmentalists now doubt that we can turn back the tide. We, and our children, will have to live with the consequences of our actions, and the actions of our parents and grandparents.
