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

If you read Drawdown, you'll see that it doesn't cost money to stop climate change, it saves money.

I don’t like that we’re even talking about money in this context. Money is almost fake, it’s right there in the ‘fiat’ name, yet that’s all most people care about.
