- burning gasoline, coal and other fossil fuels has unnaturally heated the atmosphere
- "Scientists are pretty well done arguing about whether the warming in the last 50 years is related to burning fossil fuels," Mote said.
- Experts advise taking steps to prepare for the coming changes -- because even if the pollution stopped tomorrow, the warming would continue.
- Few scientists dispute that adding carbon dioxide and other greenhouse gases to the atmosphere traps more of the sun's heat. Sophisticated tests show that the concentration of CO2 in the atmosphere is at its highest level in at least 650,000 years.
- Most of the excess heat caused by industrialization, along with about half the extra carbon, has been absorbed by the oceans. That is making the oceans more acidic, which can kill microscopic animals known as plankton and inhibit the growth of protective plates of microscopic plants -- both at the base of the food chain.
- The international science panel also concluded that an increase in strong storms in the Atlantic, such as Hurricane Katrina, "more likely than not" resulted from climate change. The same effect is expected here.
It is "very likely" -- a 90 percent chance or better -- that burning fossil fuels caused unnatural temperature increases over the last half-century.
- Temperatures are likely to rise from 2 to 11.5 degrees by 2100. (The world has warmed about 9 to 12 degrees since the depths of the last ice age 20,000 years ago.)
- Sea levels are likely to rise 7 to 23 inches by the end of the century, although an additional rise of 3.9 to 7.8 inches is possible.
-Oceans will keep growing more acidic.
- Arctic Sea ice will disappear by 2100.
- Desertlike conditions will expand in the...
