- A study published in the journal "Nature Climate Change" in 2021 found that climate change has already caused at least a 4% decline in global fisheries catch potential. The study found that the largest declines were in tropical regions, where fisheries are particularly vulnerable to rising ocean temperatures.
- A study published in the journal "Science Advances" in 2022 found that climate change has caused the distribution of many fish species to shift towards the poles by an average of about 100 kilometers (62 miles) per decade. This shift is expected to have major consequences for fisheries, as many fish species may move into new areas where they are not currently caught.
- A study published in the journal "Nature Communications" in 2023 found that climate change is causing the timing of fish migrations to change. The study found that some fish species are migrating earlier in the year than they used to, while others are migrating later in the year. This could disrupt the timing of fishing seasons and make it more difficult for fishers to catch fish.
These are just a few examples of the many ways that climate change is affecting fisheries. The impacts of climate change are already being felt around the world, and they are expected to worsen in the future. This will have major consequences for food security, livelihoods, and economies around the world.
