“Scientists investigated the factors that influence forest cover in California’s Sierra Nevada. Bedrock may be as important as temperature and moisture, they found, in regulating the distribution of trees and other vegetation across mountain slopes.” Quoted from the National Science Foundation press release.
“Data from satellite sensors show that during the Northern Hemisphere’s growing season, the Midwest region of the United States boasts more photosynthetic activity than any other spot on Earth, according to NASA and university scientists.” Quoted from the NASA press release.
The Weather Channel has some interesting photos of some snow covered trees from in northern Finland, near the Arctic Circle. If you didn’t know the scale you might think that they are clouds from an atomic or volcanic blast.
“The ravages of deforestation, wildfires, windstorms and insects on global forests during this century are revealed in unprecedented detail in a new study based on data from the NASA-U.S. Geological Survey Landsat 7 satellite.” Quoted from the NASA press release.
A number of coal-fired power plants are experimenting with adding wood to their fuel stream. It is viewed by some as a way to boost the use of renewable fuels, improve emissions and lower the carbon footprint of the coal plants. The problem: The supply of wood is not reliable!
“Peru’s cloud forests are some of the most biologically diverse ecosystems in the world. Researchers have new evidence that shows rapid 21st century warming may spell doom for tree species in Peruvian cloud forests, with species losing 53 to 96 percent of their populations.” Quoted from the Wake Forest University press release.
The renewable fuel standard program requires refiners to blend ethanol with gasoline. The Environmental Protection Agency approved a 15% ethanol blend, which many believe will harm engines, result in lower gas mileage, divert farm resources away from food and squander water resources.
“Throughout the Sierra Nevada, high flat plateaus are found at elevations around twelve and thirteen thousand feet. These isolated sky islands are the home to unique plant communities that are found nowhere else.” Quoted from the Yosemite National Park video description.
