im gonna go ahead and copy paste what i wrote on RC about this.
Humans are responsible for aprox 3.2% of the carbon dioxide released into the atmosphere anually (from about 5-6 billion tons).. The earth naturally releases 90billion tons of CO2 from our oceans and around 60+ from our vegetation. so around 150-160 billion tons total.
Carbon dioxide makes up only 5-7 percent of all the greenhouse gasses in our atmosphere. The most common, and the gas which absorbs more thermal radiation, is WATER VAPOR, accounting for about 90-95% of ALL GREENHOUSE GASSES...
How, in just over 100 years of industrial revolution, polluting only a miniscule fraction of the carbon dioxide, and an even smaller fraction of total greenhouse gasses, did we cause global warming?
Also
I think global warming is a real event, we just aren't causing it. The earth goes through heating and cooling cycles, it looks like we are at the begining of a warming cycle. Our 5% contribition is probably having little to no effect on the total temperature changes going on.
Actully at night they do relese CO2 in small amounts. In the latest Discover magazine there was an article about how large forest areas they have discovered that these areas relese methane gas along with O2. They then took a look from space and found that across the world there are large pockets of methane gas over expansive areas of vegitation which they never knew that before.......In the new Coral magizine it has an article about how the oceans (they found out through a study) releses more methane gas then any one specific contributor on the planet. Now we are not being a proper care takers of our world but, the doom and gloom that the secular left like AL Gore are pervaying isn't totally accurate either. Can we do better absolutely, are we as big a contributor as purposed? No, but we ain't helping either.
