So the estimate in 2021 was we reach 500ppm CO2 by 2046.
4 years later, in 2025, the estimate is 500ppm by 2044.
While human activity accounts for the vast amount of CO2, volcanic eruptions can release a lot. Significant eruptions release vast amounts of CO2. We've been going through a pretty active volcanic period recently. Lots of big eruptions along the Ring of Fire. Major eruptions can block out the freakin' sun.
Warming oceans are releasing increasing amounts of methane, a more potent "greenhouse gas" than CO2.
Melting tundra is increasing in northern latitudes, releasing even more methane than before.
I'll bet there are more sources of methane and CO2 than we even currently realize, and we may or may not be able to control them.
My point is simply that the rise of CO2 is attributed to more than just human activity. And human activity is increasing around the globe. Wind power, while relatively unreliable and still carbon-intensive, is at least an attempt to "do the right thing," however misguided. I can't fault humans for it. I don't feel like I've been told that wind power will significantly slow the rise of or decrease CO2 in the atmosphere, so I don't feel "lied to." It likely helps, in rather insignificant amounts.
I have believed that nuclear power is the best option for many years. There will be accidents, like with any energy source. The Germans freaked out over Chernobyl in 1986 and Fukushima in 2011. Maybe being in closer proximity to those disasters affects how you think about nuclear power.
While I think nuclear power is the best source we have at our fingertips, I also like having a robust wind and solar power industry for a more personal, localized use. And I don't know if ANYTHING we can do will slow the rise of CO2. And I could add that getting other countries to "cooperate" with us has been close to impossible. And now WE, the US are going in the wrong direction.
