57% of teens understand that global warming is caused mostly by human activities, compared to 50% of adults;
They may "understand" it, but the remaining 43% get it right... The vast majority of global warming is caused not by human activities, but by natural climatalogical cycles as influenced by the sun and by the rotation of the earth and their influence on bodies of water. Looking at historical data, it is quite obvious that since humans came onto the face of the earth, CO2 levels are actually way down from historic highs. And that global temperatures decreased every time while CO2 levels continued to increase, proving that it is a false conclusion that CO2 causes global warming. It is quite obvious to me - and I do have a scientific background - that high CO2 levels are a result, not a cause, of global warming. And it may actually be true that increases in CO2 over time result in lower global temperatures, but there has been no cause and effect relationship established; in fact, the increases in CO2 are more likely to be a result of global warming, but that the cooling or warming of the earth's temperatures may not be the result of fluctations of CO2 or methane at all . The earth's natural processes are quite effective in maintaining an equilibrium. But what the radicals are attempting to do is change that equilibrium... that is what scares me more than anything.
71% of teens understand that carbon dioxide is produced by the burning of fossil fuels, compared to 67% of adults.
While it is true that burning fossil fuels does produce carbon dioxide, that certainly is not the only source of carbon dioxide. It is quite likely that warming of the oceans resulting in dissolution of CO2 and other dissolved gases are the primary source of such gases.
46% of teens understand that emissions from cars and trucks substantially contribute to global warming, compared to 49% of adults;
Methinks that emissions from automobiles have recently been proven not to substantially contribute to global warming. In fact, based on reports just this week, the production of CO2 in the U.S. has decreased in the last couple of years.
Why do you assume the other 43% got it right??
8% thought Reagan and Bush were fully responsible
5% thought Mr. Bean had something to do with it
3% blamed emo kids......
lol /sarcasm
