Global Warming, climate change and meteorology are a part of Earth Science and Environmental Studies.

Chapter List

1.) Climate Has Changed Before

00:05:26Earth'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.

2.) The Industrial Revolution

00:11:32The 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.

3.) Hydrological Cycle

00:05:39The 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.

4.) Biogeochemical Cycles

00:01:07BioGeoChemical cycles circulate atoms, molecules and particles through the atmosphere.

5.) Nitrogen Cycle

00:05:07The 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.

6.) Methane Cycle

00:02:23The 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.

7.) Aerosol Cycle

00:02:38The Aerosol cycle involves aerosols, which are minute particles suspended in the atmosphere.

8.) The Carbon Cycle

00:05:47The 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.

9.) The Greenhouse Effect

00:04:46The Greenhouse effect is caused by greenhouse gases - carbon dioxide, CO2; water, H2O; Methane, CH4; and nitrous oxide, N2O.

10.) Greenhouse Gas Demonstration

00:06:17A Greenhouse Gas which produces the greenhouse effect is carbon dioxide.

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.

Chapter List

1.) Adaptation and Mitigation for a Warmer World

00:05:12Global warming solutions involve adaptation and mitigation to work with changing ecosystems.

2.) Mitigation

00:05:34Mitigation 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.

3.) Wind power

00:04:50Wind 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.

4.) Hydrogen Fuel

00:05:48Hydrogen 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..

5.) Photo Biological Hydrogen

00:04:17Photo Biological Hydrogen from the algae, clamata Monus, is a photosynthetic hydrogen, a form of bio-energy.

6.) Ethanol

00:06:00Ethanol 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.

7.) Thermal Chemical Conversion of Biomass

00:05:22Thermal Chemical Conversion uses a biomass to create a liquid fuel such as hydrogen or methane and is carbon neutral.

8.) Solar

00:07:18Solar, or solar power, employs photovoltaics, solar cells, and is currently undergoing a new generation of technology that uses semiconductors, nano crystals and quantum dots.

9.) Adaptation

00:08:11Adaptation is how humans will cope with a changing world such as the sea level goes up as with the sea rise.
