Suddenly science is starting to realize the importance of tree's.



Trees are much better at creating clouds and cooling the climate than we thought....

The pre-industrial atmosphere contained more particles, and so brighter clouds, than we previously thought. This is the latest finding of the CLOUD experiment, a collaboration between around 80 scientists at the CERN particle physics lab near Geneva. It changes our understanding of what was in the atmosphere before humans began adding pollution – and what it might be like again in the future. Most cloud droplets need tiny airborne particles to act as "seeds" for their formation and growth. If a cloud has more of these seeds, and therefore more droplets, it will appear brighter and reflect away more sunlight from the Earth's surface. This in turn can cool the climate. Therefore understanding the number and size of particles in the atmosphere is vital to predicting not only how bright and reflective the planet's clouds are, but what global temperatures will be.

The CLOUD experiment at CERN also recently discovered that gases emitted by trees can stick together to make new seeds for clouds in the atmosphere – without needing any help from other pollutants as was previously thought.

Recent findings from CERN


So how are our tree's doing....



The statistics paint a grim picture. According to the World Resources Institute, more than 80 percent of the Earth’s natural forests already have been destroyed. Up to 90 percent of West Africa’s coastal rain forests have disappeared since 1900. Brazil and Indonesia, which contain the world’s two largest surviving regions of rain forest, are being stripped at an alarming rate by logging, fires, and land-clearing for agriculture and cattle-grazing

National Geographic


Regardless if we believe that CO2 is increasing from man made pollution or naturally, from a warming earth. Its clear that a warming earth is melting the Alaska's and Siberia's permafrosts which increases atmospheric CO2, promoting greater tree growth.



Dr. David Schimel from NASA's Jet Propulsion Laboratory found in a recent study that, contrary to popular ignorance, carbon dioxide isn't necessarily destroying the planet as we've all been told. Any carbon surpluses resulting from natural warming or cooling cycles are actually helping improve biodiversity in many of the world's most remote ecosystems, including in the great rainforests of South America.

In terms of climate change, this means that trees and other plant life thrive from the carbon released into the atmosphere

So increased tree growth from increasing concentrations of CO2 might be considered the earths natural climate thermostat which helps cool the planet. But if tree's are being destroyed faster than they are replenished, the thermostat will fail to modulate the climate. So instead of trying to profit from increasing amounts of atmospheric CO2, we need to preserve our remaining worlds forests, free from human intervention.

A spanner in the works is a theory suggested by Henrik Svensmark Solar-Cosmic Ray Theory . That cosmic rays increase cloud formation when the suns magentic field weakens which typically occurs during periods of low sunspot activity (Maunder Minimum etc which occurred during last little Ice Age). With NASA forcasting that the next solar Cycle could be one of the weakest in centuries. Does that mean we could very be headed into another Little Ice Age if his theory is correct.

A recent study supports Henrik Svensmark theory...



A recent study published in the Aug. 19th issue of Journal of Geophysical Research: Space Physics supports the idea of an important connection between cosmic rays and clouds. According to spaceweather.com, a team of scientists from the Technical University of Denmark (DTU) and the Hebrew Univerwsity of Jerusalem has linked sudden decreases in cosmic rays to changes in Earth's cloud cover. These rapid decreases in the observed galactic cosmic ray intensity are known as “Forbush Decreases” and tend to take place following coronal mass ejections (CMEs) in periods of high solar activity. When the sun is active (i.e., solar storms, CMEs), the magnetic field of the plasma solar wind sweeps some of the galactic cosmic rays away from Earth. In periods of low solar activity, more cosmic rays bombard the earth. The term “Forbush Decrease” was named after the American physicist Scott E. Forbush, who studied cosmic rays in the 1930s and 1940s. The research team led by Jacob Svensmark of DTU identified the strongest 26 “Forbush Decreases” between 1987 and 2007, and looked at ground-based and satellite records of cloud cover to see what happened. In a recent press release, their conclusions were summarized as follows: "[Strong “Forbush Decreases”] cause a reduction in cloud fraction of about 2 percent corresponding to roughly a billion tonnes of liquid water disappearing from the atmosphere."

Regardless of an uncertain future in which the only constant we can count on is change. We do know that trees create Oxygen from CO2. And Oxygen is more important to us than profit

Plant a tree or two.

Burning trees to make electricity is becoming quite popular. Why? It's classed carbon neutral.

Let's go to hemp. There are so many products made from hemp, we wouldn't need to use nearly the amount of trees we do. Shut down the lumber barons and welcome the hemp barons.

That's just sad. In Australia we have had public opposition to wood-fired power stations. Although some still exists today they cannot be listed as green electricity in some states. Nor new ones built.

Now this is good stuff!
I have planted over a thousand trees/shrubs
in my lifetime. Not mono culture either.
Enough to cover my carbon footprint,
and yours.


The deforestation that has been occurring
is downright criminal on this planet.
In fact it is self destructive.

I don't have anything against hemp but feel that a combination of solar, wind and tidal energy can power most of the earths needs for the forseeable future without needing to burn anything for energy. We just need to have more energy efficient homes and appliances to realize the potential of being totally pollution free.

Unfortuantely industry is slow to move. It still operates in a generation when energy was cheap. We still drive around in cars that weigh 10X more than its occupants. We need to introduce new technology into mainstream far quicker as increases in the cost of energy is negative to economies.

While I agree about planting trees, I must correct some things.

1) Our CO2 emissions exceed the rise in atmospheric CO2, so it's pretty clear we're doing it.
2) Oxygen does not come from CO2, but from the H2O in photosynthesis; additionally, plants become more efficient with H2O as CO2 rises - combined, along with our burning Carbon (creating CO2 from Carbon + atmospheric Oxygen), is causing this:

Do you realize the ramifications of that many trees?

If we had it your way, we'd be over run by Bigfoots and bears and other furry things in no time.
With no money to fight them.
Because we spent all of our money on trees.

You got a # park then. Cities with no trees in their park are idiotic. It isn't even a park. More like a parking lot.

Thanks Greven for the corrections.



Our CO2 emissions exceed the rise in atmospheric CO2, so it's pretty clear we're doing it.


32 million acres of tropical rainforest have been cut down, every year, since 2000 which IPCC tells us adds 10 to 15% to human attributed C02 output. But what isn't known was the ability of past forests to moderate and clense CO2 from the atmosphere. Vostok tells us that CO2 levels were cyclic between 200-300ppm. If the worlds forests still existed. Would CO2 levels have risen above 300ppm today. We simply don't know!

So human CO2 output may not be the problem. The CO2 levels might be rising unnaturally because we are destroying our habitat, crippling its ability to clense the atmosphere of CO2. So it accumulates.

While you are correct about the 02 coming from the H20, you have confused transpiration with respiration.

At increased levels of CO2 the leaf stomata of plants close smaller which also reduces the amount of water lost by the plant via transpiration. Increased C02 levels result in increased photosynthesis resulting in more C02 used up and more 02 given off during respiration.

We are in an era now of Global Greening, crop yields are up and the earths biomass has markedly increased. At levels around 150 plants DIE. 400 ppm is not dangerous, it's beneficial.

Oxygen moves through the same pathways as water vapor and CO2. Fewer/closed stomata resulting from increased CO2 levels means less O2 emission. Don't forget that plants also consume O2 when they respire, the rate of which appears to increase with enhanced CO2 levels.

Transpiration is when a plant emits oxygen and water vapor. Respiration is very similar to animals, and happens at a cellular level - input O2 output CO2.

Of course a plant that is gaining mass faster at increased C02 levels is taking in additional C02 and putting out more 02. All of the carbon that makes up a plants tissues is fixed from the C02 in the air, you know that. Plants at a higher C02 level are more efficient with water, the stomata present less open surface are for water to evaporate out of, just another bonus for us to enjoy at the levels we're at today. Crop yields up all over this world, it is a Global Greening taking place. Plant growth is going into overdrive.
