Overpopulation affects climate by Robert W. Lubbers, Bradenton to the Sarasota Herald Tribune, Saturday, November 19, 2016
With recent changes in Washington, there will be increased scrutiny on climate change. There should be. Climate change is real and has been during the entire history of the earth.
There have been a number of ice ages with warm-ups in between. The last ice age ended around 12,000 years ago, but during its peak most of North America was under a continental ice sheet as much as 10,000 feet thick.
By around 800 A.D. it had warmed enough that people settled in Greenland, built houses and had farms. Around 1300 A.D., a “mini-ice age” began and lasted until around 1850. Because of the cold, by the year 1500 most Greenlanders had either left or starved. Around 1850 A.D. the current global warm-up began and it continues today.
Solar activity, volcanoes, cosmic clouds, etc., can cause climate change. Atmospheric carbon dioxide can also cause global warming, and each person produces about two pounds of CO2 per day.
In 1927 there were 2 billion people on the earth, but now there are almost 8 billion people, and the net growth is 190,000 more people per day.
Forests remove huge amounts of carbon dioxide from the air, but in the last few centuries we have cut down 65 percent of the world’s forests. Most of this is to produce food and yet millions are starving.
Our exploding population is a major cause of global warming and might in fact be a more serious problem than our fossil-fuel usage.
