@MontereyJack,
Here is the thing that many people neglect. No where does the data say that humans are the cause behind the global temperature change. It is ASSUMED to be humans.
I won't deny the data that shows we are in a warming trend, however; I object to the conclusion that humans are the cause to this warming trend.
We have data, ice core samples that show that in the past the earth has had even higher average temperatures than the average temperatures now. This happened millions of years ago when humans weren't even around. It was actually warmer then! The earth is constantly changing climate because the system is not static as people like to assume that it is.
I think it is wrong to make the correlation that humans are the cause behind the global climate change. Here is the thing, if it is not solar activity it could be galactic. I know some will laugh because they have bought into the human cause behind global warming but recent data gathered about extinction events a reoccurring number kept appearing in the data.
Something happens roughly every 65 million years that causes massive die off of plant and animal species and it is occurring too often to be asteroid impacts. The theory behind it deals directly to our galactic activity. Some cosmologists theorize that the super massive black hole at the center of the milky way gives off bursts of radiation that spirals out along the galactic plane.
This energy wave wouldn't just hit us all at one time but instead it would build up and fade because the wave would stretch over a long distance, perhaps a light year or so in width. This radiation could impact the earth over many tens of thousands of years causing temperature and climate change.
Now I am not saying this is definitely the cause, but I am saying people are ignoring other possible explanations because they are sold on the idea that humans are behind it. The reason why I don't believe humans are the cause is directly do the the fact that we have data that shows the earth's climate changing drastically over short periods of time when NO humans were around to cause it. I believe we are undergoing a warming trend due to some "energy" or radiation that we have not detected or checked for.
Why are we not looking for other possible causes, because making people feel guilty for being the cause behind global climate change is profitable market. Make people pay for their guilt is a new form of taxation. If humans aren't the cause then no harm done but the wealthy ones who own these companies profiting off peoples guilt get wealthier over a lie. Just look at who the main leaders are pushing for these global climate change taxes. Politicians. They are investing in bad science to convince the masses that humans are the cause so they fill their company coffers with the guilt of the people. Genius.
