OCEAN WARMING & ACIDIFICATION

OCEAN WARMING & ACIDIFICATION

OCEAN WARMING & ACIDIFICATION

Almost three-quarters of Earth’s surface is covered by ocean, and another 10% is covered by ice sheets and glaciers. Since the 1980s, the ocean has absorbed about 20-30% of humans’ carbon emissions, causing the ocean to become both warmer and more acidic. In addition, the ocean absorbs more than 90% of the heat that greenhouse gases trap in the atmosphere. And as the water warms, it expands: about half of the sea-level rise over the past 25 years is attributable to warmer oceans

The consequences are far reaching, and the 2019 UN IPCC report warns that we will see “unprecedented” changes to the oceans this century. Already since 2016, half of all the coral in the Great Barrier Reef has died due to acidification, and Australia has downgraded its outlook to “very poor.” States are experiencing a host of other issues like  disappearing whales, millions of dying starfish, and threats to fish species and the fishing industry

Although the oceans are warming about 40% faster than the UN had previously predicted, another report imagines the ocean as a powerful source of solutions, including off-shore wind, if action is taken now. Another solution, championed by Bren Smith, co-founder of GreenWave, sees kelp farming as a way to both restore our oceans and feed the planet. He points out that Seaweed harvesting once was a major industry in the United States. In the early 1900s, 1,500 workers produced 52 different products from kelp on the docks of San Diego. The industry died after WWII (due to over harvesting), one recent study estimates the industry will grow to 85Bn by 2026 across a diverse range of markets.
