问答题 At the World Bank in Washington, officials have posted some new " help wanted" signs. The bank is looking for a few good specialists to focus on adapting to global warming. It"s a small start, perhaps.
46. Still, the ads represent one signal that adaptation is emerging from the political circle to take its place among the fronl-rank options for dealing with elilnate change.
47. At least in the developed world, the idea that people should start figuring out how to deal with the projected effects of warming has been overshadowed by calls to reduce carbon-dioxide emissions. Some environmentalists have viewed adaptation either as a white flag on the issue or as a refuge of cont rarians who despise the broad consensus that human activity is warming the climate.
48. But last week"s release of a report on the science of global warming—with its projections of warming based on emissions already in the air, as well as on potential future emissions trends—has helped underscore the need. " Climate change is here and now," notes Ian Noble, a senior climatechange specialist at the World Bank. "We have to adapt. "
In some cases, adaptation can be politically wrenching. Australia, for example, is facing the worst drought in a century. The drought"s length and severity is.consistent with some projections of global warming, several scientists note. The national government has proposed a controversial, $2.5-billion (Australian) plan to wrest control of the withering Murray-Darling river basin—the country"s largest river system--from the four states in eastern Australia that draw water from it. 49. Meanwhile, Queensland has adopted regulations that since last March have required each new home in the state to draw nearly 40 percent less water than pre-2006 homes.
In some towns, building codes specify the installation of large holding tanks to capture and store rain for use in the gardens and to flush toilets.
If Australia represents the dry end of the adaptation spectrum in the develop world, New Orleans and the Gulf Coast may well represent the wet end. The region is still struggling to recover from hurricanes Katrina and Rita in 2005. 50. The tragedy surrounding those two storms underline just how maladapted major population centers in the region are to today"s conditions, let acme those that might hold in 2050 or 2100, experts say. "The reality is that we should be adapting " and tackling carbon-dioxide emissions at the same time, notes Roger Pielke Jr. , a science-policy specialist at the University of Colorado at Boulder.
