Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.
Every single person is part of the problem. Some more, some less. Corporations do not harm the environment because they are inherently bad. They do it because people (all of them!) love stuff.
They do so because of perverse incentives. They socialize the costs and privatize the gains. This is a fundamental design flaw of Capitalism and in turn Corporations.
Humans harm nature in EVERY form of society.
This is a bit of a cop out though. At the moment a very small number of humans do a very large amount of the harm because there is no cost to doing so.
