And you read yet another post of mine. You said a few days ago that you don't read them.

This is almost the exact response that I expected from you... You tin foil hat conservatives are so predictable.


They told me if I voted for Hillary Clinton the president would be emotional, impulsive, and unpredictable. They were right. I voted for Hillary Clinton and got a president that is emotional, impulsive, and unpredictable.

Elevated Carbon Dioxide Making Arid Regions Greener

May 31, 2013 — Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth's atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide "fertilization effect" has, indeed, caused a gradual greening from 1982 to 2010.

. . .

The effect of higher carbon dioxide levels on plant function is an important process that needs greater consideration," said Donohue. "Even if nothing else in the climate changes as global CO2 levels rise, we will still see significant environmental changes because of the CO2 fertilization effect."

Isn't this is a form of negative feedback? As more CO2 is put in the air, more plants and trees will grow and the ones already here will grow bigger which means they will be taking back in more CO2.

And isn't it a benefit for animals and humans (and the Earth in general) if plants and trees grow bigger and the areas they encompass increases?

Areas of the world 'greened' by CO2:

Does anybody think its kind of ironic that the 'greens' don't want to make the world greener?

Maybe if people didn't read the entire article they might find it ironic.

"On the face of it, elevated CO2 boosting the foliage in dry country is good news and could assist forestry and agriculture in such areas; however there will be secondary effects that are likely to influence water availability, the carbon cycle, fire regimes and biodiversity, for example," Dr Donohue said.
"Ongoing research is required if we are to fully comprehend the potential extent and severity of such secondary effects."

It could very likely influence them in a positive way.

Given the human track record of unintentional influences on the natural system, the chance of that is astronomically low.
