For more years than we can count, oceans have helped us mitigate climate change, including the early effects of human greenhouse gas emissions. Acting as a giant carbon dioxide and heat absorber, or "sink", 90 percent of the warming that happened on Earth between 1971 and 2010 occurred in the ocean. Scientists think that gathering more and better data from the ocean and "listen" to what it has to tell us could be crucial to helping our mitigation efforts catch up to climate change.

But why the rush?
Sea levels are rising at an accelerating pace. From 2018 to 2019, we doubled the global average sea level rise – taking from from 3.2 millimeters per year to 6.1 millimeters per year. This is partly due to thermal expansion (warm water expands), and partly due to the melting of glaciers and ice sheets, which go from being solid water on the land, to extra water in the ocean. As a result of sea levels rising, floods increase in number and severity, and shoreline erosion is accelerated, destroying habitats, interfering with agriculture, and contaminating water sources.
Hotter climates are more volatile, and extreme weather is becoming more frequent.
Hotter surfaces mean more and more sudden rainfall, hurricanes, and
hotter atmospheres mean more water evaporates and storms happen.
These changes are big. Fast. And its simply not true that ocean data is adapting and growing as quickly. Much of the current scientific data is siloed and inaccessible, making it difficult for scientists and policy makers to work together.

How could we improve it?
Affordability: The bulk of ocean
research is currently undertaken by a small number of wealthier countries – leaving many coastal nations out of the exercise entirely. The tech needed to collect information isn't cheap, and there's a good chance of losing it at sea. Cheaper, more accessible equipment is needed to drive interest and investment from poorer countries.
Open data:
A drive towards open data and lower fee
barriers to publication would also improve data sharing and global
ownership of information. Collecting ocean data into combined tags,
networks, and lakes will mean fewer people repeating teh same work,
faster innovation, and more collaborations between experts. However,
companies need to be incetivised to do this. Some ways this might be
achieved is through payoff from improved oil exploration or fishing
opportunities.
These changes could be transformative. But it involves working together – just like the oceans and the atmosphere.
