Melting permafrost releases significantly more carbon than new growth will capture:
Since permafrost contains lots of organic matter like frozen plants and, occasionally, animals within, it holds an enormous amount of carbon.

Oceans are storing less Carbon as temperature rises according to NASA and Science journal ......
How Temperature Affects Carbon Capture
- Lower Solubility: Warm water holds less dissolved gas than cold water. As sea surface temperatures rise, carbon dioxide (\(\text{CO}_{2}\)) becomes less soluble, causing the ocean to absorb less from the air and release (outgas) stored \(\text{CO}_{2}\) back into the atmosphere. [1, 2]
- Reduced Mixing: Warming increases the temperature difference between upper and deeper ocean layers. Melting ice adds fresh water, making surface water lighter. This layering prevents water layers from mixing, trapping carbon at the surface and stopping deep-water circulation from restocking nutrients and carbonates. [1, 2]
- Weakened Sinks: Recent studies show that record-high sea surface temperatures cause regional outgassing—such as in the Northern Hemisphere and North Atlantic—making the global ocean absorb roughly 10% less carbon than expected during peak heat events. [1, 2]
(quick AI searches have been known to be wrong but both these fit with me knowledge of climate crisis (the need to maintain the permafrost, why adding large herbivores to Siberia would be beneficial by soil compression to slow down thawing, the science behind solubility and mixing).
I should add, apparently, that I have a degree and a masters in environmental stuff but not directly carbon and climate. My Youtube channel isn't related to any of this either
