Global Warming: Science and Solutions

Availability information for this program

Our planet is warming; it's significantly warmer in the 21st century than it was in the last third of the 20th century. Indeed, four of the warmest years on record have occurred in this century. This global warming is being forced by the unabated burning of fossil fuels pouring CO2 into the atmosphere ... And this warming appears to be forcing dramatic regional and worldwide climate shifts. This series takes you through the Science of Global Warming and the Solutions. We need only to trust the science and work together to implement these solutions... solutions we can no longer afford to ignore.

Episodes:

• The Science of Global Warming

  Global Warming, climate change and meteorology are a part of Earth Science and Environmental Studies. Climate Has Changed Before Earth's climate has changed before because of the amount of CO2 in the atmosphere, and as a result, Earth's history has had Ice Ages. The Industrial Revolution The Industrial Revolution used fossil fuels - coal, oil, natural gas - which released huge amounts of CO2 and pollutants into the atmosphere raising global temperatures, as shown by Dr. James Hanson, and leading to the Kyoto conference on climate change. Hydrological Cycle The Hydrological cycle involves water, H2O, and is part of the dynamic global balance that under the Greenhouse effect can melt glaciers raising the oceans and leading to extinction. Biogeochemical Cycles BioGeoChemical cycles circulate atoms, molecules and particles through the atmosphere. Nitrogen Cycle The Nitrogen Cycle shows how nitrogen is beneficial to plants through nitrogen fixation, but in the anthropocene era high levels of nitrogen oxides hurt the ozone and increase the greenhouse effect. Methane Cycle The Methane Cycle, involves methane which is more abundant than, natural gas, has a great impact on the greenhouse effect and could cause extinction through a methane burp. Aerosol Cycle The Aerosol cycle involves aerosols, which are minute particles suspended in the atmosphere. The Carbon Cycle The Carbon cycle is driven by life itself since carbon is found in all living things as well as fossil fuels such as coal, which releases carbon dioxide, CO2, a potent greenhouse gas creating the greenhouse effect. The Greenhouse Effect The Greenhouse effect is caused by greenhouse gases - carbon dioxide, CO2; water, H2O; Methane, CH4; and nitrous oxide, N2O. Greenhouse Gas Demonstration A Greenhouse Gas which produces the greenhouse effect is carbon dioxide.

• Global Warming: Solutions

  Energy to run the Earth's industries and homes comes from energy fuels such as fossil fuels - coal, oil and natural gas, but there are other energy fuels which are alternative energy, which can be sustainable and better for the planet. Adaptation and Mitigation for a Warmer World Global warming solutions involve adaptation and mitigation to work with changing ecosystems. Mitigation Mitigation is a means to reduce the carbon dioxide, CO2, in the carbon cycle, as shown in the Kyoto Treaty and can be seen in using water power to turn turbines as a generator of electromagnetic induction. Wind power Wind power is used by a wind machine, also known as a wind turbine, whose turbines catch the wind and convert mechanical energy into electrical energy. Hydrogen Fuel Hydrogen fuel is being investigated by the National renewable Energy Laboratory, where the means to create vast amounts of hydrogen to be used in a fuel cell are being investigated.. Photo Biological Hydrogen Photo Biological Hydrogen from the algae, clamata Monus, is a photosynthetic hydrogen, a form of bio-energy. Ethanol Ethanol one of the biofuels, is being researched at the National Renewable Energy lab, and uses corn and enzymes, similar to alcohol, to produce fuel such as gas or liquid gas, that can be used in a flex-fuel vehicle. Thermal Chemical Conversion of Biomass Thermal Chemical Conversion uses a biomass to create a liquid fuel such as hydrogen or methane and is carbon neutral. Solar Solar, or solar power, employs photovoltaics, solar cells, and is currently undergoing a new generation of technology that uses semiconductors, nano crystals and quantum dots. Adaptation Adaptation is how humans will cope with a changing world such as the sea level goes up as with the sea rise.
