turn coastal deserts into forests. Why? Forests full of trees that consume carbon dioxide are a great bulwark against the gas most responsible for global climate change.
Deserts with their lack of plant cover are terrible at doing the same thing. Key to this process is carbon sequestration.
If you can't grow a forest bring a forest to the city. note: desalination is not the answer but
or wild animals and there were no fields or forests or streams. Worst of all the air was thick and stinky.
We could make whole forests of them. To protect the forests for all time.@@Joey Carmichael;
Here's the coolest thing being printed 3-D in and around buildings all over the civilized world by everybody.
As a retired Department of Environmental Quality Employee and an owner of timber land this is a stupid article on environmentalism gone crazy in past history.
Why doesn't the author try to calculate how much forest was saved (carbon dioxide sequestered) by trapping the beavers?

#A Plan For The World's Tallest Wood Skyscraperlook at this futuristic skyscraper design! Construction for it would dump less CO2 into the atmosphere than traditional steel construction!
It'd be made out of--uh wood actually. The proposed design from architecture firm C. F. Mà ¸ller would be the world's tallest wood skyscraper
and go up in Stockholm by 2023. In fact at 34 stories the building would totally dwarf the plan for America's tallest wood building
which will stand at a mere six stories. There are at least a couple potential upsides to making a skyscraper with wood.
For one thing the CO2 released by manufacturing wood for building is less than it is for concrete or steel.
Since its lighter than those materials wood also costs a lot less to transport. Plus: look at the interior!
which forest they will cut down to come up w/all this wood? That's what I was going to say Pioneer tear down the rainforest home to many billions of creatures to make an apartment building for a few thousand.
#Using Wood As Biofuel May be Worse For The Planet Than We Thoughttimber harvesting may release significant amounts of carbon into the atmosphere according to a new study.
This challenges a longstanding belief that using wood for energy is a green alternative to fossil fuels.
But after reviewing multiple recent research papers about decreases in soil carbon levels the authors concluded that intensive forest management practices can cause large amounts of underground carbon to flow into the atmosphere.
Our paper suggests that increased reliance on wood may have unintended the effect of increasing the transfer of carbon from the mineral soil to the atmosphere.
-Clarkewere trees replanted (like tree harvests for timber and paper here in the south) or was erected a development in its place?
Chopping down forests doesn't just make our land less pretty or put plant and animal species at risk:
Much of America's forests are owned privately. So one can easily make the case that
You can do your part by looking for the FSC logo on wood and paper products that you buy.
and huge spaces paved for cars is also the biggest contributor to forest and green space destruction.
and suburban sprawl chopping down Orange groves forests farms etc is only possible with Auto Addicted transit.<
However the entire forests of the upper midwest were cut down a century ago and that habitat destruction contributed nearly no increase in green house gases
or truck to haul away the wood) But that is where you wander off. Trees don't sequester CO2 they BREATH it in as an indispensable component for photosynthesis
Cutting down forests is carbon-neutral; it doesn't release carbon. But it clears the way for another tree to be planted in their place.
it's nothing famous like the giant panda or Amur leopard but instead the forest coconut native to Madagascar.
It's estimated that there are fewer than ten adult forest coconut trees left so um yeah sounds pretty endangered.
One of today's leading theories suggests that our forest-dwelling ancestors began walking on two feet as climate change stripped away the trees they lived in forcing them to move to the ground.
Rocky terrain would have provided more protection than forests since many large African carnivores can't climb.
When the Forest Service asked the Federal Aviation Administration for permission to use unmanned aerial systems to monitor wildfires the FAA said no
the Forest Service could fly the drone so long as an operator on board another aircraft could see it at all times.
And even if an organization like the Forest Service gets timely permission that permission often comes with the stipulation that drones be followed with a manned chase plane.
and training officer at the federal Forest Service. Rusty Warbis the flight operations manager at the Bureau of Land Management said the process of approving individual trial flights was âÂ#Âoecumbersomeã¢Â# though improving.
The Forest Service part of the Department of agriculture has also been studying drone use for years. Mr. Hanks of the Bureau of Land Management said one question was how much value drones would bring to existing firefighting methods.
My backyard sounds like a jungle. We also had lots of weeds this year and last.
Forests died out. The poles covered with ice. Many of the flora and fauna that had populated the planet during the Eocene just couldn't survive in the new colder world.
They live in tropical forests; they're specialized for that kind of habitat. So the monkeys we now know which live in the warmer

But we'd need continuous forests from southern Mexico on northwards and dryness is an issue though in the future they might get increased rainfall.

To investigate this Finnish researchers collected data from forests in 11 locations around Earth. They measured aerosol concentrations plant gases average temperatures and the height of something called the boundary layer
That could mean heavily treed areas--like the boreal forests of Canada Siberia and Finland--could warm up more slowly than heavily populated areas in more southerly latitudes.
while the amount of forest acreage in the US has increased greatly during that same period?
It maps the relative impact of three different forest management strategies: logging but replanting trees or selective-use;
or conserving forests altogether would result in financial gain: certain areas would take a hit (the timber industry obviously
and also agriculture) but more industries like tourism and fisheries would improve. Of course this is only based on research for a single park
so data for other forests would be at least a little different. You've got to wonder what this chart would look like for a place like the Amazon.
If planting of trees was done on a large enough scale they create their own weather like rain forest keep the USA wetter.
It has people in the forest moving around and clearing brush. Thanks to the biggest pyromaniac of them all Smokey the Bear we've been seeing an uptick in the devastation of forest fires
Those loggers statistically are protecting the entirety of the forest out of the incentive to destroy only some of it.
Timber companies harvest trees on private land and in national forests and then replant them.
The U s. is a major exporter of wood but we also manage to have more trees today than a century ago as brian144 pointed Out in Sumatra it's far easier to export trees than it is to import tourists to offset the value of the trees not being harvested.
Old growth forests are not the source for these products wood is most commonly a farmed product. www. popsci. com/science/article/2013-04/solar-panels-now-make-more-electricity-they-use@adaptation. It was my understanding that solar panels only pay themselves off in a short period of time
To ensure that these air bubbles were the culprits behind the acoustic signature of drought-parched trees the researchers mocked up a tree in the lab. They placed a thin piece of pine wood complete with its xylem intact into a capsule filled with a gel.
You can think of a photon as a drunk person walking through a forest. The drunk person enters the forest and walks into a tree D'oh!
changes direction (scatters) and walks another short distance and into another tree D'oh! D'oh!
âÂ#Â. and before you know it the drunk person exits the forest in a random place going a random direction.
When photons enter the skin it is just like the drunk person walking in the forest.
But it is important to consider that skin is more complex than the forest analogy.

Whiter rabbits will always do better in snow than black rabbits shorter-legged boars will always do better in denser jungles) The still unproven part of the evolutionary theory (it's still a theory) is Macro Evolution.
That musky smell under the canopy of an old growth forest is...you guessed it Methane.
With the availability of fermented fallen fruit on the ground those forest-dwellers with the ability to digest alcohol would have had an evolutionary leg up.

However when you view more forests over the surface of the planet it is clear that no two forests are the same
Yeah sure 5 million buffalo but that was before we wiped out half the forest of the earth
Hell the rain forest are disappearing as we speak so no plants or algae and you have higher methane and co2.
Not tho mention the fact that there is currently a far greater acreage of the US covered by forest than there was 100 years ago thanks mostly to the commercial timber industry.

It is like cutting a tree in a forest-soon replaced. Oakspar you're assertion appears to be that individual lives don't matter.
All lives matter because unlike a tree in the forest they affect the world beyond the space they take up.

Beyond that the coalition has promised to restore hundreds of millions of acres of former forestlands
and to halt global forest destruction entirely by 2030. Razing and burning forests accounts for about 10 percent of present global carbon emissions or 3. 6 billion tons of CO2 a year.
Currently eight football fields worth of forest is degraded or destroyed every ten seconds according to the World Wildlife Fund.
So if it's successful the plan's impact on carbon dioxide emissions could equate to taking every single car On earth off the road.

As part of the declaration Norway the U k. and Germany among others pledged $1 billion to developing countries such as Liberia and Peru for preserving forests.
As Popular Science reported live from the climate summit last week a coalition announced a new commitment to stop tropical forest and peatland loss related to the palm oil industry.
They have pledged also to stop buying palm oil from suppliers that destroy forests for the creation of plantations.
But palm oil has been the cause of intense rates of forest and peatland destruction ecosystems that would otherwise be storing much more carbon than the palm plantations that replace them.
These tropical forests are also important biodiversity hot spots that support incredible wildlife. Shinta Widjaja Kamdani of the Indonesian Chamber of commerce tells the press that this pledge is not just about signatures on a page

#One-Third Of Borneo's Rainforest Has been Cut down In part it's because of the high-quality forests on Borneo the world's third-largest island an incredibly biologically diverse landmass that is divided between Brunei Indonesia
Between 1980 and 2000 more wood was harvested from Borneo than from Africa and the Amazon combined for example.
The study documented forest loss by using satellite images which can gauge by how much light is reflected
and some statistics kept by the Indonesia for example are highly suspect underestimating forest loss the authors wrote.

The next day we set out into the forest. A five minute walk away we find the first decoy a relatively well-made one that looks like spider albeit with six legs.
To spot one you walk slowly through the jungle with your headlamp beam on even at high noon;
the canopy darkens the forest more than you'd expect and the light helps pick out the delicate white webs
Six months earlier while researching butterfly diversity Reeves discovered a similar spider in the jungles of the Philippines that likewise makes spider-shaped decoys in its web albeit of a slightly different shape.
Over the course of my trip and Reeves's month in the jungle he goes about laying the groundwork to test this hypothesis

But not just any wood. The tower s strength and mass rely on a highly engineered material called cross-laminated timber (CLT.
The enormous panels are up to half a foot thick. They re made by placing layers of parallel beams atop one another perpendicularly then gluing them together to create material with steel-like strength.
This construction has more in common with precast concrete than traditional timber frame design Thistleton says.
When it opened in 2009 Stadthaus was by far the world s tallest modern timber building.
It s become a competition among architects to see who can build the next tallest wood high-rise says Frank Lam a professor of wood building design and construction at the University of British columbia.
or concrete CLT also known as mass timber is cheaper easier to assemble and more fire resistant thanks to the way wood chars.
Wood is renewable like any crop and it s a carbon sink sequestering the carbon dioxide it absorbed during growth even after it s been turned into lumber.
Waugh Thistleton estimates that the wood in Stadthaus stores 186 tons of carbon while the steel and concrete for a similar conventionally built tower would have generated 137 tons of carbon dioxide during production.
but sturdy residential-building system of thin wood beams introduced during the mid 9th century (so light people said that it might just float away).
and San francisco. These disasters led to strict local construction codes that limited the height of residential wood buildings to as low as five floors.
The great forests of skyscrapers that grew across the world s cities in the 20th century were made almost entirely of steel and concrete.
There was a long period where people forgot how to use wood says Alex de Rijke a partner in the London architecture firm of drmm which has worked extensively with mass-timber design.
But over the last two decades architects and engineers have begun to rethink the possibilities of wood as a structural building material.
In the mid-1990s the Austrian government funded a joint industry-academic research program to develop new stronger forms of engineered wood to soak up the country s oversupply of timber.
Normal wood is strong in the direction of the grain but weak in the cross direction.
And because it relies on layers of smaller beams it can reduce waste by using odd-shaped knotty timber that lumber mills would otherwise reject.
and send them to an engineer who would convert the documents into specifications for each wood beam or steel plate.
and sends them to robotic wood or steel routers which shape panels with millimeter precision.
It took just 27 days for four men working three days a week to erect the timber portion of Stadthaus about 30 percent faster than a comparable steel-and-concrete structure.
Whatever client came in timber came on the table says Waugh and after an hour timber all too often came off.
The resistance arose from assumptions about wood as a material: Clients believed that any wood structure would behave like a balloon frame with its structural weaknesses and vulnerability to fire.
We found the journey at times frustrating Thistleton says. One thing we found was the inability of anyone to distinguish between mass timber and a timber frame.
Fire is of course the first concern that comes to mind with wood construction. And yet mass timber is actually safer in a fire than steel.
A thick plank of wood will char on the outside sealing the wood inside from damage. Metal on the other hand begins to melt.
Steel when it burns it s like spaghetti says B. J. Yeh the technical services director for APA he Engineered Wood Association.
When the Australian arm of Lend lease a global project management and construction company began to design Fortã Â a 10-story apartment building in the docklands neighborhood of Melbourne its engineers were not considering mass timber.
We originally looked for a lightweight construction solution that could work on relatively poor soil conditions says Andrew Nieland who oversees timber construction projects for the company.
and came across engineered timber Neiland says. Generally speaking CLT construction is about 15 percent cheaper than conventional steel and concrete according to research by Waugh Thistleton.
But the biggest driving force behind the turn toward wood is a growing awareness among architects and developers about their field s contribution to climate change.
Wood on the other hand ven engineered wood like CLT which requires additional energy to cut and press into sections s far more environmentally friendly.
According to Wood For good an organization that advocates for sustainable wood construction a ton of bricks requires four times the amount of energy to produce as a ton of sawn softwood;
and cool a wood building. When CLT is used to build high-rise towers the carbon savings can be enormous.
Called the Timber Tower Research Project it reimagines Chicago s 42-story Dewitt Chestnut apartment tower
Overall the proposed building is about 80 percent wood with steel and concrete at the joints to provide added stiffness.
The process for producing cross-laminated timber makes clear why architects call it plywood on steroids.
Beams of wood usually spruce are set down side by side in layers with each layer perpendicular to the one beneath it creating a wood board up to a foot thick.
