The Planet Is Greener Thanks To CO2
Posted on: Thursday, May 26, 2016 Comments
If there’s anything that climate crisis theology clerics hate more than fossil fuels, it’s got to be any glad tidings about CO2. Like, for example, results of a global satellite study published last month in the journal Nature.
It reported that thanks to that "pollutant", the planet is producing lots more veggies, so even the most strident non-carnivorous ideologically-superior planetary salvationists should really celebrate. This is great news!
As it turns out, based upon simulated ecosystem models, the researchers credited 70 percent of this green bounty to CO2 fertilization benefits. They attributed another 9 percent to nitrogen fertilizers and 4 percent to shifts in land management, neither of which explain observed added forest growth.
Also, according to a 2013 study of temperate and boreal forests in the Northern Hemisphere (also published in the journal Nature), there was a substantial increase in water-use efficiency over the past two decades which was much larger than predicted by biosphere models.
This was attributed to increased ecosystem-level photosynthesis, net carbon uptake and decreasing evapotranspiration (water loss).
And here’s the part some authors of the most recent report obviously had to struggle with: they attributed the third biggest beneficial influence - 8 percent - to "climate change".
As for claims that CO2 fertilization benefits are temporary, leading CO2 plant growth authority Craig Idso who chairs the Center for the Study of Carbon
Dioxide and Global Change finds no empirical evidence exists to support a model-based claim that future carbon uptake by plants will diminish due to rising
temperatures.
Actually, just the opposite has been noticed in the real world.
Increased CO2 fertilization allows plant leaves to extract more carbon from the air - lose less water - or both - during photosynthesis, a process that converts sunlight and soil nutrients into sugars which fuel life.
Also, a lot of plants tolerate heat better when CO2 levels are higher - a condition evidenced by satellite imagery of deserts and savannas where greenery expansion is more apparent than in wet locations.
In many regions of the world a warmer planet will lead to more precipitation and longer growing seasons - this results in far fewer deaths from starvation and winter hypothermia.
