Preliminary Study Data: Increased Carbon Levels Spark Extra Growth In Trees
And thus increased CO2 consumption from the trees overall, according to preliminary data from a long-term study funded by the DOT.
The 10-year experiment in Oak Ridge showed that higher levels of carbon dioxide enhanced productivity of sweetgum trees - at least for a while. Absorption of carbon dioxide and conversion to wood, leaves, roots and sugars took place at an increased rate.
“This is important because if forests across the Earth absorb carbon from the atmosphere a bit faster, the carbon dioxide from fossil fuel combustions won’t build up quite as fast, and the greenhouse effect causing climate change will be slowed,” Norby said, emphasizing that the change won’t be stopped.
The increased productivity occurred mostly below ground, the scientist said. Instead of making more wood in the trunk, the trees enriched with carbon dioxide made more roots, he said. These fine roots only live for about a year and then deposit their carbon into the soil, he said.
This illustrates one of the areas of the “global warming” debate that seldom gets talked about: Our environment’s amazing ability to adapt.
Let’s remember that so-called “pollutants” like CO2 (which every animal on this planet exhales) occur naturally in nature. Is it really so surprising that nature would be able to evolve to compensate for higher levels of it in the atmosphere?
While nothing is for sure, the truth may be that our environment is perfectly capable of adapting to increased human carbon emissions and that any radical efforts to curb them (or eliminate them altogether as some climate change disciples call for, though that would require us all to stop breathing) are simply a waste of time.
