At least they are reporting it, sort of hedging their bets.
It’s a baby step, but it’s a step.
You're right that it is good to see it mentioned. The three years is of course wrong in many ways. The dip in solar TSI alone is at least 0.1% whereas the entire increase in greenhouse effect so far is 900 / 160,000 or 0.56% rise. Three years worth of manmade CO2 will give us a rise of about 8 ppm which is about 3 / 160,000 or 0.002% For comparison the sun is 80,000 (all number in TW)
But they are also ignoring the effect of low solar on weather which causes even more cooling. That said, the solar dip isn't going to push us into a Little Ice Age or we would see some effects already. Instead there is a lot less snow over Siberia and other signs of warmth.
This is why they’re working on population reducing microbes.
Especially microbes that reduce the older and useless eater populations.
