Humans have caused 1.5 °C of long-term global warming according to new estimates

Looking into the numbers a couple if months ago I was surprised how little it costs to stop climate change.

On the order of 100-200 trillion USD. Which is roughly 100-200% of global yearly GDP. Or 2-5% of yearly GDP until 2050. This could well be provided by printing money at all the federal reserve banks.

This investment will likely bring in a positive return on investment because it reduces the negative climate impacts.

Without such investments the downstream costs in climate change adaptation will be very expensive

There is a demographic conflict of interest between those who will be alive in 2050 and those who will not. The long-term gains are difficult to deny. The short-term costs, however, will be massive.

The price of renewables has plunged to be cheaper than fossil fuels, battery tech is improving while prices are dropping, new jobs are created, etc, etc.

Making these changes are investments with real payoff in the near term.

The real impediment is that fossil fuels have made some people incredibly rich, and they are actively fighting these changes to protect their income.

Is there a source for this? If you're referencing LCOE, remember that does not account for storage costs for intermittent power sources (wind, solar) so it's an incredibly misleading number.

First hit on google: https://gasoutlook.com/analysis/u-s-renewable-energy-beats-f....

Roughly parity for LCOE once storage is added.

Battery prices continues to drop and in short order it will be flat out cheaper with storage included: https://rmi.org/the-rise-of-batteries-in-six-charts-and-not-...

Add to that investments in the national grid and general energy efficiency it's doable: https://www.nrel.gov/analysis/100-percent-clean-electricity-...

Again, the only reason to not pursue this is to keep the fossil fuel companies profits flowing, and that isn't very compelling.
