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.
On top of that, there are systemic problems that allow the situation to escalate out of control. Why should I do this expensive thing while everyone else gets the cheap option? This sort of thinking applies to governments, companies and individuals alike. Nobody wants to contribute to fixing the problem, because it’s expensive.
