Our leaders are stupid but not that stupid.
At some point they will finally understand that economic growth is no longer possible and permanent economic contraction is guaranteed due to falling net energy.
At that point they might implement aggressive measures to reduce CO2 emissions. This will allow them to blame climate change for a shrinking economy and thus avoid the panic, hoarding, and wars associated with wide-spread understanding of overshoot and limits to growth.
On the other hand…
History strongly suggests there is no limit to human stupidity and we will blunder into full on collapse and wars over the remaining scarce resources.
