Now you put it like change is there all the time.
Thats easy to agree.
Lets see if the home made changes are bearable.
human greenhouse gasses account for about 1/10 of 1% of total greenhouse gasses. that's a pretty insignificant amaount. i'll grossly over-simplify for you. let's say that temperatures rise 100 degrees from such gas activity(which is bullocks). then the human amount would be 1/10 of a degree.
i don't "trust" in cooling.
the thermometer shows that temperatures are down. i don't deny warming has/is occured(ing). the earth has been much warmer at other times, for example about 400 a.d. when Europe was so warm that houses were built without indoor hearths. i expect it to reach higher temperatures in the future. no amount of governmental action or carbon taxation will change that.here's a REAL place that human activity warms the environment: concrete. large amounts of blacktop and concrete act as an a heat sink. they hold heat and release it slowly. the local area around concrete and blacktop is definitely warmer than areas of natural land or plant life, as anyone who's traveled on a motorcycle knows. the efffect is only localized however. if the thermometers are in rural areas, they tell a much different story than if the thermometers are in a city. cities are a miniscule part of the earth's surface, however, even though to the city dweller, the city seems to dominate the earth. as i pointed out before, all 6 1/2 billion people fit in the state of Texas with 1100 square feet per person.
