I don’t deny that there has been global warming. That’s usually what happens when ice ages end. Yes, there has been an increase in CO2 and CO2 is a greenhouse gas. So is methane. The biggest greenhouse gas is H2O in the form of clouds. Overall climate is always changing.
BUT, and it’s a big BUT, for all the claims that our carbon emissions (and now cow farts) are the sole, or even major, cause of the warming there is not one model that I can find that tracks the actual climactic record. I’m not talking a year or two here and there, but going on decadal trends. When the models are that far off, I can’t give much weight to the conclusions that are drawn from them. Climate is such a chaotic system with so MANY inputs that trying to tie it to just the one input of carbon emissions is ludicrous.
We only have accurate global data for the last 50 years or so out of 4.5 billion years. When I read about data falsification, that creates big questions as to what we can believe. When I see “corrections” like, for instance, growing city’s heat island effects on recorded temperature, that are so inconsistently applied and in only certain circumstances giving questionable results that even a 5th grader could see, that also casts a lot of doubt on the results.
As an aside, global warming and higher CO2 aren’t even all bad – higher CO2 = higher agricultural yields. More people die from cold than heat. There was a reason that Greenland was called Greenland when it was first settled during the Medieval Warm Period when it was warmer than it is now. There was another similar period during the heyday of the Roman Empire. There is no “right” climate.
But the prophets of doom would have us beggar our society in the cause of these unprovable assertions. We are ordered to limit our energy to only “sustainable” sources at high costs for an admittedly small (very small) net lowering in global CO2 levels in the air at an admittedly large (very large) cost.
Guess what? The sun doesn’t always shine and the wind doesn’t always blow. Battery storage prices are still way too high. There are only so many dams that can be built and, even then, only in some places. We still haven’t solved the societal question of dealing with nuclear wastes. That leaves fossil fuels as the only universally available and most affordable source for power generation. Coal is the most common and least expensive. However, there’s no proven affordable method of “carbon sequestration” yet, for all the EPA’s claims to the contrary. Big Oil is the Great Satan of the environmentalists with fracking for natural gas not far behind.
Why not let people decide what they want to believe? Let the market find economical methods to sell in the name of reducing carbon emissions. Those research projects have been going on since before there WAS a global warming boogie man. Those trade-offs should be made by the people themselves, using their own resources, not governments spending other people’s money with reckless abandon.
