The demonization of the “miracle molecule,” carbon dioxide, continued last week with the announcement that its concentration had reached 410 parts per million (ppm). Nearly all reporting of this noted that this was the highest level in 800,000 years and predicted a host of associated climate calamities. While the current concentration of this vital gas is about 40% higher than at the start of the Industrial Revolution, unreported is that Earth has been suffering from steadily decreasing and perilously low concentrations of CO2. Until the consumption of fossil fuels began liberating this important gas from ancient rocks , the Earth had been flirting with dangerously low levels not seen for more than 600 million years.
During nearly all of Earth’s history, carbon dioxide concentration was at many multiples of our current level, averaging 2,600 ppm, or 6.5 times our current measurement. Forerunners of most of the plants we rely on for sustenance first appeared around 150 million years ago when CO2 levels were more than 2,000 ppm. Since that time CO2 has fallen steadily and precipitously.
In fact, at the end of the last ice age, carbon dioxide reached the dangerously low level of 182 ppm, thought to be the lowest since the Pre-Cambrian time period more than 600 million years ago. Why is it dangerous? Because 150 ppm is the lowest level at which plant life can survive. We came within a whisker of breaching that “line of death.” Until we began adding CO2 to the atmosphere, there was no guarantee that this horrific threshold would not be crossed in the future.
Rather than spreading fear of increasing carbon dioxide, we should be thankful that both the Earth and humanity are thriving, in part due to more CO2.
It has been long known that increasing CO2 benefits plant growth through the CO2 fertilization effect. Recognizing the benefits of this, greenhouses often increase CO2 to 1,500 ppm. Research from laboratory studies by the Center for the Study of CO2 and Global Change have documented that a 300 ppm rise in CO2 levels would increase plant biomass by 25 to 50%. This significant boost in plant productivity, along with a boost from lengthening growing seasons, means that we are better able to feed a hungry planet.
An additional significant benefit from this increasing CO2 fertilization is that the plants have smaller stomata (pores) and have lessened water needs. Less water used means that more stays in the ground and is leading to increasing soil moisture across much of the planet and a “greening” of the Earth. According to NASA, up to 50% of the Earth is “greening,” in part due to higher CO2 levels. This increased soil moisture is a primary cause for the long-term decrease in forest fires and droughts worldwide.
The benefits of increasing CO2 don’t stop with accelerating plant growth and increasing soil moisture. The biological impacts section of the 2014 white paper Climate change reconsidered II provided quite a lengthy list of additional benefits in addition to those mentioned above. The main points are listed below:
More CO2makes plants grow faster and with less stress.
Forests are growing faster in response to increasing CO2.
More CO2stimulates growth of beneficial bacteria in both soil and water.
CO2fertilization, leading to more plant growth, means less erosion of topsoil.
More CO2means bigger crop yields, and more and bigger flowers.
More CO2fosters glomalin, a beneficial protein created by root fungi.
More CO2helps plants to create natural repellants to fight insect predators.
Although I do not pretend to speak for the planet’s flora, I am quite certain that, if plants had a say in the matter, they would not lobby for reductions in CO2 levels. For plants, CO2 is food. They need more of it, not less.
Fine Hawaii!
I like it fine...until I have to mow the yard in 90% humidity and 95 degrees. LOL
Ping.
CO2 is plant food.
Without it we all die.
If everyone who believes CO2 is a dangerous pollutant stops emitting it personally we could solve this problem overnight.
CO2 and warming are bad because they helps plants to grow, which in turn helps to feed people, but the Evnviro-weenies and the elites want to kill off a large part of mankind.
Can’t have people thriving.
For you millenials who don't know a piston from a steering wheel, ask your fathers. Oh wait, many of you don't have fathers or too metro to understand an internal combustion motor. Either way, your welcome for me adding to your food supply.
That’s what goats and sheep are for.
Or walkways and topiary.
Or concrete and gravel.
Mowing is a lifestyle choice.
A good way to do your part to reduce carbon dioxide is to stop breathing.
Atmospheric CO2 concentration is a LAGGING INDICATOR of climactic temperature.
LOL! Yeah, I know. But my neighborhood association would go “commie” if I brought in a herd to do that.

When I was a kid, I read an illustrated version of Jules Verne’s novella “Dr. Ox’s Experiment”, which I found to be very entertaining, even if, as I knew then, technically inaccurate.
People lived in a windless valley, that had over time built up an overabundance of CO2, leading it to become a very relaxed, peaceful place. A Dr. Ox and his assistant arrive with the promise of free gas lighting via hydrogen produced through electrolysis, with the extra oxygen just released into the air. He has ulterior motives, but the end result is some light comedy.
The only error was that Verne assumed that more oxygen would make plants grow better.
Based on research by Svensmark and Calder, CO2 has nothing to do with climate. Read “The Chilling Stars” to get the real story. We’re going into a period of global cooling thanks to our very quiet star.
:: CO2 has nothing to do with climate ::
Only that it an ^indicator^, as I said. CO2 has no active part, it reflects climate activity like a mirror.
My tagline (in case you missed it).
If we have moved into an area along the galactic rim of higher particle flux density then add in the weakening of the earth’s magnetic field. We could be really be screwed!
I wonder what the magnetic fields of Jupiter & Saturn are doing?
The liberals will next ban oxygen as it is a far more potent greenhouse gas then carbon dioxide....
That's true, but doesn't change the fact that the current rise in CO2 is mostly manmade. The oceans did warm naturally maybe a degree or two over the last few centuries or so. That's enough to create a rise of 5-10 ppm in atmospheric CO2. The rest of the rise, including annual rises of 2-3 ppm are due to manmade CO2. Whether that manmade CO2 creates more warming is not reqlly in doubt, but the amount is probably small. The doomsters have to fudge the models with extra water vapor and weather pattern changes to get a lot of future warming.
Oxygen (O2) is not a greenhouse gas. The main reason is that vibration modes are very small compared to molecules like CO2 and H2O.
