...write, my town is installing solar-power panels on our town-hall building. Every government on the planet must start thinking globally and acting locally. Paul Feiner, Town Supervisor Greenburgh, New York, U.S. The report on global warming makes a convincing case that our planet is getting hotter, but shouldn't we at least be considering the possibility that we are going through a natural cycle that we can't stop or lessen? All the solutions focus on reducing carbon dioxide, which may be a good idea, but shouldn't we also be thinking about how we can adapt...

Reducing carbon dioxide may be a good idea, but shouldn't we also be thinking about how we can adapt to environmental change, as all species have had to do at some point...
...result of all that is warmer oceans, and a result of warmer oceans can be, paradoxically, colder continents within a hotter globe. Ocean currents running between warm and cold regions serve as natural thermoregulators, distributing heat from the equator toward the poles. The Gulf Stream, carrying warmth up from the tropics, is what keeps Europe's climate relatively mild. Whenever Europe is cut off from the Gulf Stream, temperatures plummet. At the end of the last ice age, the warm current was temporarily blocked, and temperatures in Europe fell as much as 10°F, locking the continent in glaciers...
...constituents, climate change is about the Cascade Mountains, where the city gets its water and hydropower and where the snowpack has shrunk by half over the past 50 years. It's about the effect of Puget Sound's warmer waters on wild-salmon runs. It's about hotter summers cooking up more smog. It's about a rise in sea level that could flood Seattle's port. "The stakes are high--globally and locally," he says. "We need...
INSECTS The news here is not all bad. Ticks, for example, may not be able to survive hotter temperatures in the southwestern U.S. And global warming is unlikely to have much of an effect on malaria, as long as you focus on lowland areas (because those regions already have so many mosquitoes). That picture may change, however, as you move upward in elevation. Malaria has seen a dramatic upswing since the 1970s in highland cities like Nairobi (around 5,500 ft. above sea level). How much of that can be tied to temperature increases--as opposed to population movement, lapses...
