Solar energy production has increased 20-30% year over year every year for the last decade. If this continues peak oil production will occur in the next five years, if not 2026 itself. The wars in Iran and Ukraine are added global motivation for this change.

The velocity and acceleration of CO2 and energy production are the far more important metrics.

>Lets hope we don't reproduce the PT event.

When/if we really need to we can spend tens of billions to fertilize ocean deserts and trigger thousand mile scale algae/jellyfish blooms and maybe nuke a few mountain ranges in the right places to hard accelerate biological and chemical capture of CO2.

If the ice caps actually melt we can replicate the Azolla event when, to simplify, the arctic ocean became much less salty and freshwater essentially duckweed covered the ocean causing global climate change.

Enacting forced major climate change in a restorative direction is entirely within our grasp to prevent mass extinction events, they just have their own caveats which have to make it worth it before we go for it.
