Still, the planet won't cool down only because we start using solar energy. We should actively remove CO2 and methane from the atmosphere. Planting trees is likely not enough.

This other article from 2017 https://www.nationalgeographic.com/magazine/2017/07/antarcti... states that

> the last time atmospheric carbon dioxide was as high as it is today, and the temperature was about what it’s expected to be in 2050, sea levels were up to 70 feet higher than today.

That's going to cause mass migrations in all countries of the world, rich and poor, and destroy the logistics that let us live like we do now. Obviously we'll adapt but there are going to be maybe billions of deaths (famine and diseases). I think I'm lucky because I'll be dead by then. However I could see the first coastal cities going a little bit underwater.

Ultimately we elect our politicians so we are responsible for what they decide and not decide to look at. We'll get what we deserve.

The price drop in $ per kWh generated by solar, wind and hydroelectric, etc, has nothing to do with the growing concentration of greenhouse gases. You can look at greenhouse gas causing figures such as how many megatonnes of coal are burned each year, how many barrels of oil Canada exports to the USA each year, they're all on a steady climb.

The world has an inexorable thirst for energy. It's great if there are more watt-hours being generated by green sources, but at the same time, there is what seems to be an inexorable growth in pollution causing sources. Example: Look at how many cars are sold each year to the growing middle class in China and India.

You forget the third player, fossil energy companies who are keen to protect their business and fight against this change. Politicians don't keep out, they are just as likely to help the old companies.
