People lose war for the ground: most methods of CO₂'s removal from the ocean have been guilty

The ocean covers more than 70% of the planet's surface and retains an incredible amount of carbon dioxide. Earlier, researchers have already stated that to restrain climate change and limit the warming by less than 2 ° C, it is necessary to reduce greenhouse gas emissions, as well as the removal of carbon dioxide.

As a result, scientists and private sector companies have offered a wide range of potential approaches to achieve an annual speed of removal of CO2 in billions of tonnes over 30-50 years. In focus. Technology has appeared its Telegram channel.

In a new study, scientists at the University of Eastern England (UEA), the Institute of Marine and Antarctic Studies of the University of Tasmania, the National Center for Scientific Research and the Institute of Sustainable Development and International Relations considered the climatic effectiveness These methods are very valuable and have many non -climatic advantages, however, unfortunately, they do not make a significant contribution to the process of removing carbon dioxide.

In simple words, in terms of significant mitigation of the effects of climate change, all these methods may be in a dead end. At the same time, scientists say that new methods of removal of carbon dioxide from the ocean are offered regularly, but they contain many balances and restraining factors. This is especially true for the methods of removal of carbon dioxide based on the ocean.

This method today is of great interest to scientists around the world, especially because the restriction of terrestrial methods of CO₂ removal is becoming increasingly obvious. The study authors believe that supporters of natural carbon dioxide removal methods from the ocean have an incomplete or misconception of how the carbon cycle of the ocean operates, as well as the scaling of the CO₂ removal process required to produce significant climatic benefits.

As a rule, scaling of a particular method of removal of carbon dioxide leads to the emergence of other oceanic processes that can negate all benefits. The team found that in each of the four learned methods there are misunderstandings and gaps in knowledge that influence in general the trust in the carbon removal scheme.
