Three trillion trees: Study finds there are 7.5 times more trees than previously believed

My question as well. Tiny saplings? And what (species) counts as a tree?

[TomGuy]

That is atrocious!!!

Think of all the CO2 they are pumping into the air. It is going to kill us all!!

It is the fault of that Save-the-Trees movement from several decades ago.

Trees converted to lumber no longer produce CO2.

I have 20 maples growing in my eavestrough do they count?

Bout tree fiddy.

Water vapor accounts for something like 95% of the greenhouse effect on Earth, yet the global governance (gorebull warming) crowd rarely ever mentions it.

In 1859 however, the Comstock Lode was discovered in Virginia City, Nevada. During the 1860s Tahoe became the center of a lively commerce involving the silver mines in Virginia City and the Central Pacific Railroad (which was pushing over the Sierra toward the town of Truckee). The Comstock era resulted in large-scale deforestation of the Tahoe Basin, as timber was required to build mine shafts and support growing developments. It is estimated that over 80 percent of the Basin's forests were clear cut during this time.

It doesn't take all that long really to re forest, Tahoe today aside from the damage done by beetle is a thriving full forest.

Science: today’s best guess.

Only if you put them in the ground on Arbor Day..................B^)

Trees TAKE IN CO2 and GIVE OFF O2....................

LOL!.................

I remember a couple decades ago, there was a big complaint that “X number of acres or square kilometers/miles” of Amazonian rain forest was being cut down every day/month/year and that all of that virgin forest was being destroyed. Someone actually took the figures and calculated them and discovered that the numbers had to have been imaginary, because the ‘acres cut’ came to be about twice the land mass of north and south America, or some similar size.

Could be a Global Tree epidemic?

[GeronL]

After admitting their estimates were off by a freaking lot they make another

I bet you dollars to donuts there are more trees in the continental US today than when Columbus first came close to North America.

Ah..that a BIG CO2 sink to miss...(as plants breath in/consume CO3)

Ive question the computer climate models on how they model plants vs animal's (flora vs fauna) both are dynamic in growth vs decline... so co2 emitter (fauna) vs co2 consumer (fauna) are always changing

I have thought that it might be flora/fauna cycle driving part of the ice age / warming period cycles

...aka a warm co2 environment would favor fauna..as the plants expand.. they consume co2 emitter o2 to the point that it changes the co2 /o2 balance ...and we going it to a cooling..this lead to a die back of plants and expansion of animals.. who are o2 consumers co2 emitters.. so cycle again to warm.....

Using a combination of satellite imagery, forest inventories, and supercomputer technologies, the international team of researchers was able to map tree populations worldwide at the square-kilometer level.

The supercomputer technologies requires some human input. So I believe there may be 15X more trees in the world than originally thought. Did they count the 11 trees I have planted in the last 5 years? I doubt they would show up on satalite.

Sting.................I remember that ................

How large does a tree have to be to count?

Interesting question considering how many libs view the start of human life.

[Osage Orange]

I bought 8 tree’s in the last 4 years.....

[Tenacious 1]

Well, that shoots all the Man-Made-Global-Warming computer models to hell. Now they have to re-run the calculations to determine the earths O2 absorbtion rate. That would further decrease man’s .00016 contribution to CO2 collecting in the atmosphere.

....don’t hold your breath.

I have more trees on my property now than when I moved here 13 years ago. I cut down the old, diseased, and trash trees and replaced them with new young trees and fruit trees..................
