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.”
Unfortunately for climate alarmists, the entire theory is based on positive feedbacks creating runaway catastrophes. Thus they can predict silly things like global warming will somehow produce global cooling and we will end with snowball earth and of course we will all die! If you happen to be a young person with little experience of life, you might react to the global climate change cult with over the top fear just like St. Greta of Thunberg at the U.N.
Matt Ridley, at Human Progress points out that:
This greening is good news. It means more food for insects and deer, for elephants and mice, for fish and whales. It means higher yields for farmers; indeed, the effect has probably added about $3 trillion to farm incomes over the last 30 years. So less land is needed to feed the human population and more can be spared for wildlife instead.
Yet this never gets mentioned. In their desperation to keep the fearmongering on track the activists who make a living off the climate change scare do their best to ignore this inconvenient truth. When they cannot avoid the subject, they say that greening is a temporary phenomenon that will reverse in the latter part of this century. The evidence for this claim comes from a few models fed with extreme assumptions, so it cannot be trusted.
This biological phenomenon can also help to explain the coming and going of ice ages. It has always been a puzzle that ice ages grow gradually colder for tens of thousands of years, then suddenly warmer again in the space of a few thousand years, at which point the huge ice caps of Eurasia and North America collapse and the world enters a warmer interlude, such as the one we have been enjoying for 10,000 years.
Attempts to explain this cyclical pattern have mostly failed so far. Carbon dioxide levels track the change, but these rise after the world starts to warm and fall after the world starts to cool, so they are not the cause. Changes in the shape of the earth’s orbit play a role, with ice sheets collapsing when the northern summers are especially warm, but only some of these so-called “great summers” result in deglaciation.
Recent ice cores from the Antarctic appear to have fingered the culprit at last: it’s all about plants. During ice ages, the level of carbon dioxide in the atmosphere steadily drops, because colder oceans absorb more of the gas. Eventually it reaches such a low level – about 0.018% at the peak of the last ice age – that plants struggle to grow at all, especially in dry areas or at high altitudes. As a result gigantic dust storms blanket the entire planet, reaching even Antarctica, where the amount of dust in the ice spikes dramatically upward. These dust storms blacken the northern ice sheets in particular, making them highly vulnerable to rapid melting when the next great summer arrives. The ice age was a horrible time to be alive even in the tropics: cold, dry, dusty and far less plant life than today.
The good news for humanity is that CO2 has been increasing, partly becasue of man's use of fossil fuels, but more generally because of the warming itself. If we want a greener planet, we meed to keep pumping more carbon into the atmosphere. the current level of CO2 is just over 4 parts per million (4 ppm), but 6 ppm is not too much, and it would help all life.
Clearly, climate alarmists are anti-life.
