Effective measures in reducing global warming include minimizing the reliance on non-renewable energy, incorporating energy systems that are powered by renewable energy, increasing fuel efficiency for transportation, cutting down on tropical deforestation and building cleaner, greener homes and communities. Ordinary citizens are also empowered to lobby the government to implement stricter legislation in imposing limits on carbon emissions and other greenhouse gases.Continue Reading
Earth absorbs solar energy to warm its surface, releasing some of the energy into the surroundings in the form of heat. When heat cannot escape back into space, the planet's temperature continually increases, which leads to serious environmental and health concerns. Global warming is primarily caused by the heat-trapping mechanism of greenhouse gases, or GHGs, in a phenomenon known as the greenhouse effect. The main source of greenhouse gas emissions is the combustion of fossil fuels. Primary GHGs include carbon dioxide, nitrous oxide and methane.
Fossil fuels, such as coal, natural gas and oil, are nonrenewable sources of energy. The industry and majority of households heavily depend on these materials to power machinery, heating systems, appliances and other electrical devices. These activities directly contribute to global warming. One way to reduce consumption of these resources is to incorporate the use of solar, wind and geothermal energy, which generate a cleaner source for power. Installing energy efficient products, such as those marked with the Energy Star label, also help in reducing global warming, according to Natural Resources Defense Council.Learn more about Conservation
