About CO2

The concentration of CO2

The concentration of CO2 in the atmosphere has increased rapidly throughout the past century, from 280 parts per million (ppm) to 385 ppm, a 38 percent increase. It might seem that one bright spot could be that the greater CO2 level would be helpful for plant development. However, that might not be the case. Plant Growth: Based on Dr. Surendra Singh, a biologist with a background in botany, modern plants have adapted to the 280 million ppm CO2 concentration which has been around over the last centuries. There's no reason to feel that the rising CO2 concentration would be better for crops since CO2 is seldom the limiting agent in plant growth and production. Plants also require water, nitrogen, phosphorous, potassium, sun, and trace elements.

Plants need CO2

Over-fertilizing, over-watering, or placing a shade plant in bright sun will harm the plant. More is not necessarily better, and also the increasing the CO2 levels may also harm plants that are not accommodated to high CO2 levels. Certainly, plants need CO2, but to state more CO2 will make all plants grow is a fantastic supposition and oversimplification. The planet's atmospheric CO2 level has become 385 ppm, possibly higher than it's been in the last 20 million decades, and it is increasing every year. By minding more CO2 into the atmosphere each year, we are running a fantastic experiment with unknown outcomes. What's going to occur if the production from agricultural plants reduces considerably? The concentration of CO2 in the atmosphere is increasing rapidly due to our use of fossil fuels.

Great simplification

Since plants need CO2, it might seem that the CO2 increase would be good for plants. But, that is a great simplification because the increased CO2 levels may not be good for most plants or for humanity. He taught physics, chemistry, and basic science at the college level for 38 decades. Since retirement, he has established , a website which examines current events from a science and research standpoint. Historical Data proves that the concentration of CO2 from the air has varied widely over the Earth's history, from over 7000 ppm from the Paleozoic age to a low of 180 ppm through ice ages. Ice core studies demonstrate that throughout the last four ice ages, the CO2 concentration was roughly 180 ppm throughout the cold periods and climbed to about 280 ppm during the warmer interglacial periods.

The warmer temperatures

Warmer temperatures occur at the same instances as the higher CO2 levels, so it is hard to sort out the effect on crops caused by CO2 changes from those due to temperature changes. Ancient plants that grew at higher temperatures and CO2 levels during the Paleozoic Era accommodated to the fall in CO2 level and temperatures near the conclusion of that era by developing leaves. Ancient leaved species, for example Ginko and Magnolia, when subjected to high levels of CO2, alter their foliage structures. Other plants have accommodated by changing the elevation where they grow.
