World Green House Gasses Emissions

World GHG Emissions Flow Chart.


After feedback from the previous version I've extended the duration, added colour correction, re-mapped the clouds and put the ice back at the North Pole as I'd forgotten about the cooling fins below the scrith in the polar areas...

Wildfire and Pine Beetles

Mountain pine beetles are native to Western forests, but in recent years their numbers have skyrocketed. As they damage more trees and kill whole regions of forest, some worry that the dead forest left behind has become a tinderbox ready to burn. But do pine beetles really increase fire risk?Using Landsat satellite data, University of Wisconsin forest ecologist Phil Townsend and his team are discovering that pine beetle damage appears not to have a significant impact in the risk of large fires. In fact, it might even reduce fire risk in some instances.

Hurricanes cool the Atlantic

As water vapor evaporates from the warm ocean surface, it is forced upward in the convective clouds that surround the eyewall and rainband regions of a storm. As the water vapor cools and condenses from a gas back to a liquid state, it releases latent heat. The release of latent heat warms the surrounding air, making it lighter and thus promoting more vigorous cloud development. Movie from NASA Scientific Visualization Studio (SVS)

Fossil Foolishness

Utah's Pursuit of Oil Shale and Tar Sands. Two unconventional energy sources in Utah are attracting attention as possible solutions for our national energy needs. But the high cost in water, energy inputs, pollution, and disruption make these marginal energy sources more of a problem than a solution. See why Utah has so much at risk if oi shale and tar sands become part of its future.
