The uncertainty of science: According to new research the world’s tree canopy has grown by almost a million square miles since 1982.
While the area of bare ground and short vegetation is diminishing, forest area is growing. As Ronald Bailey notes in Reason, “Forests in montane regions are expanding as climate warming enables trees to grow higher up on mountains.”
The greatest increase in tree canopy occurred in Europe, including European Russia, where it exploded by 35%. A close second was found in China, where tree canopy gained 34%. In the U.S., tree canopy increased by 15%.
This study confirms numerous other forest and agricultural research that has shown that increased carbon dioxide in the atmosphere encourages plant growth. Numerous other studies have also found that the Earth has been greening in the past century.
My review of the scientific literature on this subject also matches this finding, having found that if global warming is happening, research looking at what has actually happened generally show that increased CO2 and warming have tended to have beneficial effects, despite the endless doomsday predictions by global warming scientists of what might happen.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
