subject: Who Is Concerned With The Climate Changes? [print this page] When someone offered me a trip to India, I said, Definitely. A couple of years ago Id have fretted about the carbon emissions. But like almost everyone else, I have given up trying to prevent climate change. We in the west have recently made an unspoken bet: were going to wing it, run the risk of climatic catastrophe, and hope that it is mostly faraway people in poor countries who will suffer.Worries about climate probably peaked in 2007. That year I attended a workshop full of northern European policymakers and politicians. The moderator asked who believed climate change was a serious problem. Practically everyone in the room raised their hands. We then spent two days discussing action. I left feeling that if you were running a country like Britain in 2007, you probably thought climate change was the single overriding issue. Terrorism, immigration and even the economy were details by comparison.But in 2008 the economic crisis hit. To quote American political scientist Roger Pielke Jrs iron law: When policies focused on economic growth confront policies focused on emissions reductions, it is economic growth that will win out every time. In fact, Pielke, who teaches at the University of Colorado, thinks the pre-2008 talk about action was mostly just talk anyway. It was easier for our societies to pretend we were doing something on the issue when we felt rich, and were naive about the challenges of actually transforming our energy system, he says. But we never adopted any policies that had a chance to do the job.Nowadays few societies even pretend to be doing anything anymore. The Copenhagen global summit on climate in 2009 flopped. Carbon emissions are rising at the high end of the scenarios of the Intergovernmental Panel on Climate Change.Worse, the global economy is becoming less carbon-efficient per unit of output, as more countries turn to coal. When Japan and Germany decided to go off nuclear after the Fukushima disaster, they werent thinking about climate.Its sometimes said that democracies think too short-term to be able to tackle climate change. Well, dictatorships arent tackling it either. They, too, obey Pielkes iron law. If they can get an extra person a car, they will. Sure, countries are developing alternative energies such as wind and solar. Its handy to have something besides fossil fuels. But we will still consume every molecule of fossil fuel we can find.No big state is doing enough about climate change. For the planet, it barely matters whether Barack Obama (who believes climate change is real) or the Texas governor and Republican presidential candidate Rick Perry (who doesnt) wins next years US election. Obama wont stop climate change either. Ordinary people sense the cause is lost. The wasteful minutiae of daily life that might once have worried us -- running a big bath, eating a steak, idly Googling old classmates -- we now just do. Governments arent taxing this waste much.We journalists are dropping the topic, too. Its been a thrilling year for news, but the great absence on the news sites is climate change.Max Boykoff, a colleague of Pielkes at Colorado who tracks newspaper coverage of the issue, finds that European and north American newspapers are writing much less about it now than in 2006 and 2007. Asian newspapers are also writing somewhat less, even though their economies are doing fine. The environment bores readers.Almost everyone has given up. The question then becomes: what will happen? Nobody is sure. Almost all climate scientists think the outcome will be bad, perhaps catastrophic. They foresee more storms, droughts, floods and crop failures around the world, as Obama said in 2009 when he was still talking about these things. However, climate is far too complex a system to permit exact predictions. Nobody knows whether global temperatures will rise 2 Celsius this century, nor whether that is the tipping point for catastrophe. When climate scientists make exact predictions, says Pielke, its usually a bid to focus the minds of politicians and voters. It hasnt worked.Rich countries now have a semi-conscious plan: whatever happens, well have the money to cope. Well build dikes, or pipe in more water from somewhere else, or turn up the air-conditioning if it gets too hot. Our model is the Netherlands: the country below sea level protects itself against flooding through a network of dams, sluices and barriers. This costs about 45 euros (US$60) per Dutch person per year. The Dutch think that even as climate change raises sea levels, their defences can cope for another four centuries. By then, therell be new technologies.In short, rich countries will buy protection. If they need to abandon vulnerable cities like New Orleans or Venice, they will. The bigger problem is for poor countries. If Bangladesh floods or Nigeria dries up, they probably wont cope well. But then our mental health in the west is built on not worrying too much about what happens to Bangladeshis or Nigerians.As the professional manufacturer of complete sets of mining machinery, such as jaw crusher supplier,Sand washer supplier,Hydraulic cone crusher, Henan Hongxing is always doing the best in products and service.Mineral sand washer:http://www.hxjqchina.com/product-list_29.html Rotary dryers:http://www.crusher-machine.com/24.html
