CO2 Data Reveals Current CO2 Starvation

Two great sequestration periods occurred since the mid-Paleozoic and both appear to coincide with evolution of plants. The first woody plants and trees arose in the Middle Devonian and fueled the large coal swamps of the Carboniferous Period. Later explosion of the flowering plants (angiosperms) occurred in the Cretaceous. All the while additional C was being locked up in limestones. Also in high TOC (Total Organic Carbon) muds that were converted to the shale/mudrocks that we are now liberating with fracking.

  1. Those poor, poor starving plants. Why do climate alarmists attack plants? They want us to plant billions of them to convert them into financial instruments but starve them of their food.

    1. I assume that the strong dip int the above chart that represents the Carboniferous and Permian eras represents the uptake of C02 by plants, and also demonstrates that even then the plants were able to remove enough C02 from the atmosphere to starve themselves of it. There is not enough C02 at present to optimally promote life.

      I expect that when Global Cooling becomes apparent that the dodgy international financiers behind the endless warming scam will do a spectacular backflip and then charge the world even more for the ‘valuable C02’ in the atmosphere.

  2. The Earth is greening from CO2 fertilisation. Even NASA, in the US, has admitted that .

    However, more recent research in Europe has claimed that the greening is almost over, that however much the atmospheric carbon dioxide increases, if nutrients and water do not increase in parallel, plants will not be able to take advantage of the increase in CO2.

    I suspect that there is a mechanism whereby this, at the very least, is partially resolved. The extra carbon dioxide that is taken up by plants does not necessarily stay in them.

    Plants, including leaves, fruits, roots and trunks, can die just like every other living thing. This can result in organic matter decomposing into soil. Further, herbivores can eat plants and deposit manure which contains organic matter that can add even more carbon to the soil. Even the death of herbivores can add carbon to the soil that was once in plants and, prior to that, in the atmosphere.

    Soil carbon can have two particular benefits – it can make water and nutrients more readily available to plants. Therefore, adding more carbon dioxide to the atmosphere not only increases the growth of plants directly, but also indirectly by improving the soil.

    Now, Australia constitutes five percent of the World’s land mass but Australian soils contain only three and one half percent of the World’s soil carbon stores. Therefore, it is not hard to see that Australia stands to benefit more from this CO2 fertilisation than most other nations.

    That goes for our natural ecosystems just as much as for agriculture. And there is another benefit to boot. The greening increases rainfall. In the World’s driest inhabited continent, that is another big plus. More rainfall here means more organic matter breaking down and entering the soil, which also improves the recycling of nutrients. There is also the matter of extra atmospheric CO2 assisting plants to use water more sparingly.

    I expect that the greening will go on for some time yet.
