We know what pollutant gasses we produce (methane being the worst), we know the quantities we’re producing (record CO2 pollution this year,
exceeding even worst-case predictions), we know these gases have heat-trapping properties, and we know what those properties are. This is solid science.
The IR absorption of CO2 is lower than the IR absorption of water vapor. Or, for you non-scientists, this means that clouds have more impact than CO2. Further, a very large portion of the atmosphere is clouds, while a tiny fraction of it is CO2. The variability in the amount of cloud cover is completely out of control of man, and several orders of magnitude more impactful than CO2. This disproves the core of global warming theory.
The claim of "Global Warming" is that at some point we might run into a runaway greenhouse effect. But the reality is, both CO2 and temperature, have been much higher in the past than they are reasonably projected to get now, without this greenhouse effect showing up. Notably CO2 has been higher by orders of magnitude more than the "scare" numbers they're screaming about, in the distant past, before the wheel was invented, without negative effect. Global Warming is disproven by history as well.
Coupled with that, we know our current warming trend is unprecedented
This is a flat out lie. The planet has been getting warmer and cooler in every ice age cycle as far back as people can measure. Further, it has been doing this with every sun cycle as well.
Since we recently came off of a solar maximum, for the last several years the planet has been getting cooler. Despite this, over the very same time period, these same tinfoil hat types have been screaming that CO2 is rising faster than ever! You know what? That right there disproves their theory, once again. CO2 UP, global temperature Down. (which is why they call it "climate change" now, but that's even more absurd since that's just another term for "weather".)
We also know much of the harm that warming causes, and will continue to cause (from melting glaciers
You know how much harm has come from melting glaciers? Really? Based on what study? Can you point to a single study of the net growth or decline in glacier sizes across the globe?
You can't, because there is no such study. There are millions of glaciers in the planet-- in fact, so many, that nobody knows how many there are. Nobody has ever counted them all, let alone measured whether they are melting or not.
All talk about glaciers melting due to "global warming" is anecdotal. But Glaciers melt and grow every year and whether they gain or lose year to year is certainly dependent on weather patterns, so in order to make a claim about a global effect, you'd have to study all of them.
As the glacier example, and your ignorance of the effect of cloud cover, shows, the proponents of global warming are not basing their opinions on science. They are basing it on anecdotes and aspirations.
Global Warming is a political movement perpetrating a scientific hoax in order to gain political control over industries.
The socialists a century ago used the claim that they were protecting the workers in order to install socialist and communist and fascist regimes around the world. Of course, as we can see today in North Korea and in the past in the USSR, these "workers paradises" are anything but.
That dog don't hunt anymore.
So, they're ginning up a fake crisis in the name of "global warming" to try and take over industries exactly the same way.
Anyone, with any scientific knowledge, who looks into this, doesn't buy it. Disproving global warming is trivial: The IR absorption of CO2 is less than water vapor. Cloud cover has hundreds of thousands of times the impact on global temperature than "greenhouse" gasses.
This is why, rather than trying to convince people... these scientifically ignorant hoaxers always take the position that its "settled science" and anyone who points to scientific fact is a "denier". Even their fake term "greenhouse gases" implies the existence of a greenhouse effect that is proven to not have happened (otherwise the planet would have become uninhabitable millions of years ago.)
Anyone perpetrating the Climate change hoax is not to be taken seriously. And when you find them, if you challenge them on the science, you'll find they don't have any. All they can do is link to propaganda sites and their "authorities" are politicians with a vested interest.
