There’s a war against happiness. Climate alarmists bury good news and exaggerate bad news. They have made up their minds to be miserable and they’re determined to take the rest of us down with them.
For example, have you heard that over the past 30 years there has been a 14 percent increase in the Earth’s green vegetation? Deserts are getting smaller and forests are getting lusher. That gain even has a name: “Earth Greening.” Not surprisingly, 70 percent of it stems from the increased carbon dioxide in the atmosphere! Zaichun Zhu, one of the scientists who measured the greening, says it’s equivalent to adding a new continent of green vegetation twice the size of the mainland United States.
The benefits of the increased vegetation are widespread: “It means more food for insects and deer, for elephants and mice, for fish and whales. It means higher yields for farmers; the effect has probably added about $3 trillion to farm incomes over the past 30 years, so less land is needed to feed the human population and more can be spared for wildlife instead.” We’ve given a raise to all commercial farmers around the world. Increased supply eventually results in reduced prices.
The connection between increased carbon dioxide and increased plant growth is a perfect example of “negative feedback” in that the added vegetation from Earth Greening takes CO2 out of the atmosphere. A physicist friend of mine reminds his students, “We live in a negative-feedback world. If we didn’t, we wouldn’t be here.”.............. To Read More...
