Time to begin 'adapting' to climate change?
At the World Bank in Washington, officials have posted some new "help wanted" signs. The bank is looking for a few good specialists (two, to be precise) to focus on adapting to global warming.
It's a small beginning, perhaps. Still, the ads represent one signal that adaptation is emerging from the political doghouse to take its place among the front-rank options for dealing with climate change.
At least in the developed world, the idea that people should start figuring out how to deal with the projected effects of warming – changing temperature and rainfall, shifts in growing seasons, more bouts of severe weather, and rising sea levels – 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 contrarians who pooh-pooh the broad consensus that human activity is warming the climate.
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 climate-change 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. 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 gardens and to flush toilets.
