#ARCTIC. #SIBERIA. THIS IS TAIMYR. Global warming associated with climate change will lead to a decrease in fish stocks and biomass in the world’s oceans by 10 to 40 percent by the end of the century, depending on the region and the upcoming temperature rise scenario. Such data is contained in the latest report Climate Change Risks to Marine Ecosystems and Fisheries: Projections to 2100, prepared by the United Nations Organization’s Food and Agriculture specialized department (FAO), TASS reports.
“We compared, analyzed and compiled data from different models and observation systems. This allowed us to achieve the most accurate results and forecasts, which are confirmed by different models”, said Tarub Bahri, the report author.
She explained that under a low-carbon scenario that would keep global warming to 1.5–2 degrees Celsius, fish stocks are projected to decline by 10 percent by the end of the century in less than 178 countries. If emissions are high, they would lead to global warming of 3–4 degrees Celsius, in which case the decline is projected to be up to 30 percent in more than 48 countries, by the end of the century.
“In the situation with fish stocks, everything depends very much on the context, on the specific country and its dependence on fisheries in terms of economy and food security. In fact, the global situation varies greatly. There are areas where the decline in stocks is huge, while in others, on the contrary, it is almost imperceptible. 10 percent is the global average”, the expert explained.
Among the fish producing countries with the greatest risk of stock decline, FAO identified China (more than 30 percent in a negative scenario), India, Indonesia, and Peru – up to 37 percent. This group also includes Russia and the United States. However, according to Bahri, the losses can be compensated for, and her department is developing the relevant recommendations.
This Is Taimyr previously reported that by the end of the century, the Arctic ocean will absorb less CO2.
