      • Many things cause global warming.  One thing that causes global warming is electrical pollution.  Electricity causes pollution in many ways, some worse than others.  In most cases, fossil fuels are burned to create electricity.  Fossil fuels are made of dead plants and animals.  Some examples of fossil fuels are oil and petroleum.  Many pollutants (chemicals that pollute the air, water, and land) are sent into the air when fossil fuels are burned.  Some of these chemicals are called greenhouse gasses.

      • Carbon dioxide is the air that our body lets out when we breathe. With fewer trees, it is harder for people to breathe because there is more CO2 in the air, and we don’t breathe CO2, we breathe oxygen.  Plants collect the CO2 that we breathe out, and they give back oxygen that we breathe in.  With less trees and other plants, such as algae, there is less air for us, and more greenhouse gases are sent into the air. This means that it is very important to protect our trees to stop the greenhouse effect, and also so we can breathe and live.

    • If the carbon footprint made from producing a hybrid is ten times larger than that it erases it is news that should be shared. Compact florescent lights are great energy savers but are all of these exactly what they claim to be? And furthermore will light emitting diodes render CFLs obsolete before they are universally adapted.
    • Developments in mass renewable energy production in such areas as solar and wind power are of interest to all. We will also be looking back at past successful use of these energy choices. Zenith sold tiny windmills in the late 1930s that would charge a car battery that in turn would run a radio for days.
  • Stats

    These resources show stats on global warming

    • Explore the signs of global warming on this map or Google Earth. The evidence of climate change includes heat waves, sea-level rise, flooding, melting glaciers, earlier spring arrival, coral reef bleaching, and the spread of di
    • The greatest concentration of global warming indicators on the map is in North America and Europe because that is where most scientific investigation has been done to date. As scientists focus increasingly on fingerprints of global warming in other regions—from Russia to Antarctica and Oceania to South America—the evidence they find will be added to the map.
    • Average temperatures have climbed 1.4 degrees Fahrenheit (0.8 degree Celsius) around the world since 1880, much of this in recent decades, according to NASA's Goddard Institute for Space Studie
    • Arctic ice is rapidly disappearing, and the region may have its first completely ice-free summer by 2040 or earlier. Polar bears and indigenous cultures are already suffering from the sea-ice loss.

  • Video

      • Good overview of the global warming phenomenon.

        Map of world climate.
        Stats on current polar melting
        Predictions and simulations of possible effects.

    • Global warming could do more than just melt polar ice. It could change our maps, and displace people from cities and tropical islands.
