Ocean surface hits highest ever recorded temperature and set to rise further
(www.theguardian.com)
Marine heatwaves are becoming more numerous, a 2019 study found, with the number of heatwave days having tripled in the past couple of years studied. The number of heatwave days rose by more than 50% in the 30 years to 2016, compared with 1925-54. Scientists said at the time the heat destroyed swathes of sealife “like wildfires take out huge areas of forest”.
Oh we are double fucked and unfortunately the governments and super rich are doubly down on destroying the planet.
This is in part due to the fact that regulating pollutants put out by cargo ships (who in the past used the cheapest, dirtiest fuels) has led to a decrease in clouds known as ‘ship tracks’. These are real clouds seeded by pollutants from cargo ship emissions, and now that we’ve cut down on their dirty, toxic emissions (which is a good thing!), we’ve also cut down on those ship track clouds that were helping keep light and heat from hitting the ocean and warming it up.
We’ve been geo-engineering with carbon emissions, we were unknowingly geo-engineering by seeding clouds with cargo ships, and now we need to figure out how to engineer our way out of this mess. Generating clouds with inert seed material like salt from the ocean might be part of that solution.
