(62,265 posts)...every year, which was based on a correlative study of old datasets where sailors would measure the cloudiness of the sea water (they weren't measuring for plankton). It was debunked not too long after it was published: https://www.nature.com/articles/nature09952

The 1% decline would be catastrophic and absolutely impossible to reconcile, and it would have immediate and measurable effects on the atmospheric composition as each year passed. It would be completely noticed if 0.5% of all of our oxygen supply and CO2 uptake was respectively reduced and increased.
The conclusion is so huge that you don't even have to study the plankton life, all you have to do is measure the atmosphere. Such an effect is not occurring.
Mind you I need a disclaimer, I do think catastrophic climate change is in our future, ut this ain't it. Yet.
