Earth’s climate is changing rapidly.
No, it is not a hoax, not a projection for the future, not a scare tactic from whatever political or advocacy group that you or your favorite politician may not like. In our lifetimes, it has changed–generally growing warmer and often dryer, with daily weather more prone to extremes–winds, rain, snow, cold, heat, more destructive storms leading to more extensive flooding, wildfires, economic damage, deaths, etc.
The research predicting and showing climate change has been there since at least the 1970’s. Our children, our children’s children, future society will pay an even greater price than we are paying today.
One of many immediate consequences of a changing climate has been and is a noticeable loss of biodiversity–the extinction and disappearance of animal and plant species.
Could human beings eventually face this threat as well? We have seen great and even abrupt shifts of Earth’s climate in the past but, until the present day, we have not seen it during a time when human beings were the dominant species.
