alt Hacker NewsIn the global share of primary energy solar is this very small player (less the hydro, much less then coal, or natural gas, or oil), data from 2024.

How much does the increase solar production decrease world-wide CO2 emmisions? Because CO2 emissions in 2025 were still increasing. I see that in many growing countries solar power is not seen as a replacement for fossil power, but as an addition to fossil power.

There are many places where the photosynthesis is not limited in CO2 amounts, but in amounts of other elements, like iron (about one third of the surface ocean), phosphorus (tropical rainforests).

Warming of Siberia could increase methane leakage, which could increase global warming and then increase in methane leakage, the “methane time bomb”

In the Earths history, we know of periods of emission of large magnitudes of CO2. One of them is Permian–Triassic extinction event (level of atmospheric carbon dioxide rose from around 400 ppm to 2,500 ppm), extinction of 57% of biological families, 62% of genera, 81% of marine species, and 70% of terrestrial vertebrate species.

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