-->PASADENA, Calif. - A NASA-led science team has created an accurate, high-resolution map of the height of Earth's forests. The map will help scientists better understand the role forests play in climate change and how their heights influence wildlife habitats within them, while also helping them quantify the carbon stored in Earth's vegetation.

Scientists from NASA's Jet Propulsion Laboratory, Pasadena, Calif.; the University of Maryland, College Park; and Woods Hole Research Center, Falmouth, Mass., created the map using 2.5 million carefully screened, globally distributed laser pulse measurements from space. The light detection and ranging (lidar)

      Worm food or angel dust, who cares?

      Frankly: you didn't exist 50 years ago and you will not exist 50 years from today, so why would you not destroy the planet?

  • We're in an ice age now and have been for the last 10,000 years. Our ice age has been a mild one. Earth's normal condition is to have no ice coverage at the poles at all.

    Throughout history sea levels have ranged by 780 feet over billions of years. We are somewhere about 100 feet short of the top figure.

    The most likely outcome of a warmer planet will be the sudden and violent onset of a new ice age, perhaps one as bad as "Snowball Earth" was.
