Industrial livestock farming, deforestation, and fossil fuel use have released unprecedented amounts of greenhouse gases into the atmosphere. It’s been tens of millions of years since there was this much CO2 out there, and levels have never increased as fast as they did in 2015.
(As readers of prior blogs know, I have argued in favor of industrial livestock farming, when discussing this terrific documentary:http://milkmenmovie.com; but only with the relevant caveats about re-use of energy in form of manure-converting power plants and other complex issues.)
Some 97% of climate scientists agree that greenhouse gases emitted by human beings are having a dominant influence on the climate.
When records shatter in rapid succession, you know it’s time to worry. 2016 is on the way to being the hottest year ever. The last record year was 2015, which unseated the previous one, 2014. And the records are being broken by ever-greater margins.
