A 10x increase is about 6 years at the current growth rate. That's mind-boggling.

It can also be not enough. They're not mutually exclusive.

The figure I like to quote is that we need 2 to 5% of GDP spend per year to get to net zero by 2050.

We already pretty much passed 1.5C anyway, right?

Yes. If we were spending 5% of global GDP on Solar and Wind now, there'd be a slim chance. Scaling up to that in six years, as a sibling comment claims, is way too late.

I would have expected the ratio of $ spent on new fossil fuels vs. new solar to be a lot higher than 4. My mind is quite boggled.
