I just read an article that was looking at massive global warming periods in the past and thought it was really interesting and alarming. Apparently 56 million years ago, volcanic eruptions caused a period of extreme global warming, but there were warning signs that came before the event. Smaller global warming incidents like ocean acidification and carbon emissions were happening as a precursor to the big event. It is scary to think that this is what might happen to us if we continue in the direction we are going in with carbon emissions. According to the article, we could only face the precursor events if we are vigilant in addressing carbon emissions but if we stay on the track we are going, we are headed for that big global warming event.
Here’s the article if you are interested:
