Plants Absorb More Carbon Dioxide Under Polluted Hazy Skies

Full story: www.sciencedaily.com

Plants absorbed carbon dioxide more efficiently under the polluted skies of recent decades than they would have done in a cleaner atmosphere, according to new findings published this week in Nature.

Lead author Dr Lina Mercado, from the Centre for Ecology & Hydrology, said, "Surprisingly, the effects of atmospheric pollution seem to have enhanced global plant productivity by as much as a quarter from 1960 to 1999. This resulted in a net 10% increase in the amount of carbon stored by the land once other effects were taken into account."

Although reductions in sunlight reduce photosynthesis, clouds and atmospheric particles scatter light so that the surface receives light from multiple directions (diffuse radiation) rather than coming straight from the sun. Plants are then able to convert more of the available sunlight into growth because fewer leaves are in the shade. Co-author Dr Stephen Sitch from the Met Office Hadley Centre (now at the University of Leeds) said, "Although many people believe that well-watered plants grow best on a bright sunny day, the reverse is true. Plants often thrive in hazy conditions such as those that exist during periods of increased atmospheric pollution."

My trees are doing really well with all this extra CO2 floating round, but so are those damned weeds.
Not to worry, even the weeds produce oxygen, maybe that's why the air is so fresh and clean round here.

My old neighbour tells me that 30 years ago, there were four pine trees on the mountainside just above us, now it's almost a forest, 10 kms long and 0.5 km wide. It has taken over the old area that was once layed to grape vines, olive and almond trees.

One odd tree among the pines is said to be 1,500 years old, but I'm not sure what species it is, but it looks quite healthy.

What's unscientific about my trees and weeds producing oxygen?

What's unscientific about a forest growing from a few trees?

What's unscientific about a tree that has survived for over a millennium?

Plants need CO2 for creating food for the living species on planet earth, but CO2 is the enemy of the liberals Democrats who blame the food of the plants fro destroying the planet.
People of the world; beware of the left wing liberal conspiracy that blames the human beings, animals and all living species of the world as the enemies of the planet earth as the source of self-destructive gases. The evil liberals desire to remove carbon dioxide from the air causing the plants and trees to perish and disappear from the surface of the planet earth.
It is he largest fraudulent scheme against the living species of the world by the US liberal media of the anarchist Marxist George Soros and the liberal Jewish Elite media of the new York Times CNN and ABC which aim at creating international Marxist-islamic rule of Barack Obama over the people of the world by threatening them to pay or else the world will be destroyed.
Wake up the people of the world and stop the radical liberal psychos and environmentalists who hate newly born babies, puppies and cubs and brainwash youth with false accusation that they were born to destroy the world because they use air for breathing and natural energy resources which is an evil baseless accusation. The evil radical liberal hordes of Obama and his czar the delusional radical psycho Jackson are operating like an organized crime mafia who threaten people to pay them “save the world taxes” that they used for Marxist re-distribution for “a one world rule” of the poor for the poor by the poor of the world.
The dictator Obama and his hordes do not have any scientific proof for their evil claims since the real scientific measured data by real scientists of temperatures of the oceans’ water of the world prove that their claims are false and lies.
The new Islamic president-cheat of the jungles of the Kenyan Luo Tribe Barack Hussein Obama is a megalomaniac narcissist who aims at ruling the world as liberal-radical Islamic dictator who will re-distribute your tax money to his interest group gangsters of Acorn, Unions labor parasites who work for his re-election and to the islamic terrorist suicide bombers Hamas and Hezbollah under the Iranian regime.
Stop the dictator Obama’s lies, deceit and madness before it expands and destroy the world like fire in the woods.

The balance of gases we have is fine and quite a lot more CO2 in the mix wouldn't affect our equilibrium.

Of course. It just makes sense that plants would thrive in a high CO2 enviroment.

Thanks for bringing this thread back to life, marc.
It's noticeable that no one chose to rebut the story, probably because there's no rebuttal.

More CO2 = more plantlife = more food.

Life evolved in the face of climate change. Man has learned to adapt. Idiots think they can mitigate.
