I've been doing objective research for 25 years, and what I've found is that a relatively small cabal of self-interested meteorologists whose livelihoods depend on government jobs and/or research grants have contrived a theory based on a relatively small 200 year snapshot of the Earth's 4.6 billion year history that presumes capitalist-fed industrialization is the primary cause of what was formerly called "global warming" and is now called "Climate Change" (because it hasn't warmed significantly for 20 years), in order to get grant money.  There is no scientific evidence whatsoever that shows increases in CO2 to be a significant cause of global warming.  History, going back 4.6 billion years, shows wide swings of both temperature and CO2 concentrations, with temperature ALWAYS rising before the CO2 level rises.  The climate always changes, and not because of CO2.  The IPCC is a political organization, not a scientific one.
