Marine heatwaves can have severe impact on corals populations. This study demonstrates that selective breeding could quickly enhance coral tolerance to short-term heat stress by up to 1 °C. This has potential to mitigate some impacts of climate change, however urgent climate action is still needed.
That will help, but the acidification of the ocean will cause the shells of certain creatures to dissolve.. Hopefully we can correct it before we get to this point, but it isn’t looking promising.
