7.5x more than scientists thought
lol
Let’s penalize North Africa, Saudi Arabia and India for not growing enough trees.

Let’s not pretend that desert expansion is a result of human activity.
We could establish goals of x trees per square mile and send them a democrat for every square mile that doesn’t meet the goal.
A truly renewable fuel source.
How large does a tree have to be to count?
This is the other part of the global climate debate that no one talks about in politics:
Land Use. The impact of agriculture vs. forests on CO2 levels.
Perhaps this is more of a culprit, for CO2 rise, than American SUVs?
Who knows?
But then again, CO2 is not a greenhouse gas, (methane and water vapor are), so why are we talking about land use, unless we talk about its impact on methane and water vapor?
3 trillion trees take up a LOT of earth-warming CO2.
We may be heading toward another ice age!
:O!
There are 7.5 times as many trees as previously thought, but....
There are half as many trees as there were before people.
First - poor estimates strain the credibility of the estimates.
Second - most of the deforestation of Africa occurred in early human history. The implication that humans are responsible also strains the credibility of the estimates.
Dropped 46%, and yet recent studies in South America have revealed that most of the “Rain Forest” there post-dates the various MesoAmerican cultures i.e. a lot of Central and South America was deforested by the MayIncAztecs and *grew back*.
So right there I have to doubt their numbers. They’re probably also counting the desertification of the Sahara which roughly correlates to the appearance of protohominids, which they have “deemed” the start of “human” civilization.
US forest acreage hit its low in 1920 (750 million acres in 1920, out of 1045 million (not incl. Alaska & Hawaii) when Europeans arrived).
Since then we’ve been replacing forest (currently at a rate of about 3 million acres a year).
One reason is that we don’t need farmland to grow food for the horses who were the main transpostation power before cars.
In 1910, 25 to 30% of all the farmland in US was used to grow food for the horses.
Oil/gas has a FAR smaller footprint than growing food for horses — 83 million acres for horse food in 1910, compared to 16 million acres for all energy production and conversion now.
But we’d be going backwards with solar and wind, which have a big footprint.
Tree Leaves Matter !!!
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?
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?
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.....
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.
I bought 8 tree’s in the last 4 years.....
