Disease plays a role as well, with whole coral colonies wiped out by sudden sickness. That rise in illness may be linked to warmer sea temperatures, which is caused by climate change. And it's global warming that poses the most serious threat to the survival of coral. Corals have a symbiotic relationship with a kind of algae that provide nutrients and energy through photosynthesis - not to mention the vivid colors we associate with coral reefs. When corals are stressed by rising temperatures, the algae are expelled by the coral, turning the reefs bone white. That's a "bleaching event...
...Schipper also estimates a savings of 4% for every degree warmer you push your thermostat. If you're set at 70deg.F now and move it to 75deg.-a comfortable, if slightly chilly number to my mind-you save 20% of the cost and energy of your air-conditioning bill. Schipper also says the savings from more-efficient air-conditioning systems can be enormous: in many Asian and European hotel rooms, the AC and electricity are activated only when you slip your magnetic room key into a slot near the door. A program to retrofit all public buildings with high-tech...
...start now? I'd like to see both candidates call for an immediate 5deg.F thermostat adjustment, just to get the conservation ball rolling - and because it would be a "personal virtue" for each candidate to ask it of us. And I'd like to wish you all a nice, warmer summer...
...happening now. Already precipitation patterns seem to be changing, making some drier areas - like the arid American southwest - even drier, and rainy regions even wetter. (Which can be almost as destructive as a drought - last year's record-breaking floods in Britain caused $4 billion worth of damage.) As warmer temperatures creep northward, so do insects and other pests that are adapted to the heat. The results can be harrowing - the population of the tiny mountain pine beetle, which infests pine trees in the Rocky Mountain region, used to be controlled by freezing winters. But as temperatures have warmed over...
...work even harder, trying to minimize non climate-related threats to land and species even as the human population grows by billions. All are agreed that the conservation movement of the future will need to be as inter-connected as the Earth's climate itself, because in a crowded, warmer world there will be no islands. Regardless of what we do, the changes will be coming fast - a report released by the U.S. Department of Agriculture on May 27 said that global warming was already having "profound effects" in the American West, and that the future would bring increased drought...
