“Empirical data withheld by key scientists shows that since 1910 ocean pH levels have not decreased in our oceans as carbon dioxide levels increased. Overall the trend is messy but more up than down, becoming less acidic. So much for those terrifying oceans of acid that were coming our way.”
What happened to those graphs?
Scientists have had pH meters and measurements of the oceans for one hundred years. But experts decided that computer simulations in 2014 were better at measuring the pH in 1910 than the pH meters were. The red line (below) is the models recreation of ocean pH. The blue stars are the data points — the empirical evidence.” http://joannenova.com.au/2015/01/oceans-not-acidifying-scientists-hid-80-years-of-ph-data/
