There are slightly more than three trillion trees in the world, a figure that dwarfs previous estimates, according to the most comprehensive census yet of global forestation. 
Using satellite imagery as well as ground-based measurements from around the world, a team led by researchers at Yale University created the first globally comprehensive map of tree density. Their findings were published in the journal Nature on Wednesday.
A previous study that drew on satellite imagery estimated that the total number of trees was about 400 billion. The new estimate of 3.04 trillion is multiple times that number, bringing the ratio of trees per person to 422 to 1.
While the density of foliage was surprisingly high overall, the researchers cautioned that global vegetation is still in decline. The number of trees on Earth has fallen by 46{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} since the beginning of human civilization, according to the report. The researchers said they believed the findings would provide a valuable baseline for future research on environment and ecosystems.
“The previous information that we had about the global forest system all came from satellite images…we’re using all this information to provide more detailed understanding of what’s going on below the surface [of the canopy],” saidThomas Crowther, a postdoctoral fellow at the Yale School of Forestry and Environmental Studies and the lead author of the study. “The numbers that we’ve generated are going to be useful for a wide variety of applications.”







Save the Eagles International are not keen on nuclear power plants, to say the least. If they can be done without, all the better. But can they be replaced by intermittent energy like wind? This is the question that must be asked. 
He angrily rejected the plan saying he would not allow anything on campus associated with that charlatan. The President was a physicist and Velikovsky (pictured) had challenged prevailing scientific views.

It turns out that the vaunted peer review process, designed to ensure that multiple sets of experts evaluate the quality of the work before it hits the presses, had fallen apart. The peer reviews in some cases were found to be “highly suspicious” with bogus email addresses and questionable credentials.

They even have an equation for it and by using this equation they assert that the ‘escape velocity’ at their black hole ‘event horizon’ is the speed of light.
