Why is the global warming debate such a politicized one? I find those who deny its existence to have blinders on and those who scream that the sky is falling to be a bit crazy. It is scientific fact that man-made carbon emissions are increasing. It is also scientific fact that more Co2 in the air causes a greenhouse effect and thus higher temperatures. I think it is irrefutable that humans are contributing to a warming planet.
To what extent humans are contributing is unknown, but we do have fairly solid numbers on Co2 emissions - specifically, that they're up more than 13 percent between 2010 and 2020. There's roughly 750 GigaTons of Co2 that are emitted naturally, and that number doesn't vary much over tens of thousands of years. Human output, however, is now over 40 Gigatons. While we as humans only account now for about 5% of the Co2 in the atmosphere, don't tell me that that doesn't have a measurable impact on global temperatures. But don't tell me that the world is about to end either.
Because there is ONE side who wants to control the spending and alter YOUR life habits to further THEIR priorities on this issue.
There might be a measurable impact from human contributions, but it would be akin to the change in gas mileage from putting an extra 20lbs in the trunk of your car. You'd need some pretty sensitive instruments and controlled conditions to actually measure it, and whether it's there or not is completely meaningless to practicality.
Temperatures ARE rising and they are going to continue to rise even if we TOTALLY ELIMINATED CO2 production immediately. So, does it make sense to spend the bulk of our resources to trying to eliminate a SMALL PORTION of CO2 production, or would it make MUCH MORE SENSE to adapt to the changing environment, because it's going to change no matter what we do on CO2??
ALSO, check out the graph below. Frequently used by climate alarmists, it shows the PPM from Mauna Loa Observatory. Note that during the year 2020, we significantly shut down transportation and a lot of industrial processes ACROSS THE GLOBE. There were PLENTY of satellite measurements that shows a virtual elimination of all kinds of emissions in most major metropolitan areas in every country. Yet, in the aggregated data from this site, there is NO measurable change in the overall CO2 measurements. Further "proof" that if we shut down "human" CO2 we're not going to change ANYTHING.
