I believe that this phrase is incorrect: "and absorb sunlight (the albedo effect), warming the Earth".

Au contraire: albedo is the reflection of sunlight (or other forms of radiation). Was this author thinking of the changing of visible light falling on a tree, to infrared radiation?

According to the study, new forests in mid- to high-latitude locations could actually create a net warming.


Since these forests are GROWING (several percent over the last decade) we need to subtract their impact from the amount of warming attributed to man.

I thought high latitude forests GROWING has been at least partially attributed to global climate change via a few research papers. As such, it would represent a feedback mechanism that would fuel further warming. Mid-latitude forests are growing because of sociopolitical reasons more so than any other reason.

OMG,

Forests are growing because its getting warmer but the larger forests are causing warming.

The DREADED FEEDBACK LOOP has been identified.

QUICK

BREAK OUT THE CHAINSAWS before we all drown.

before trees there was carbon dioxide in the atmosphere which promoted the growth of plants and trees which removed vast amounts of the gas which cooled the atmosphere and gave of oxygen which promoted the growth of man who then proceeded to cut down all the trees because of his greed and lack of foresight then there was no longer enough trees to cope with the pollution and man dies out allowing the trees to recover and the cooling cycle began. Soylent green (the film)became the bible.

Tree projects can give people a feel-good illusion that they are slowing global warming. Scientists in the U.S. believe that the amount of carbon in fossil fuel resources is 25 times greater than could be ever sequestered in trees. Okay.

Consider how location of tree planting meant to reduce the problem can itself increase global warming. A team of US and French climate experts. They say that whether or not trees help fight global warming depends on where they are. Check out New Scientist Environment (15 December 2006)

Did I miss something? It is claimed that forests in some areas could help global warming but no evidence.
