Cars and Global Warming

One of the most eye-opening conclusions of reports is that the vehicles we choose today will affect our lives for time to come. Astonishingly, the largest category of current on the road polluters is the small car. We ask ourselves why? Well, simply because there are so many of them on the road. Cars in and light trucks our nations are a huge supply of global warming pollution. United States automobiles emit more than 333 million tons of carbon dioxide (CO2) per year, which is more than 1/5 of the nation's total CO2 emissions.
Compared with the rest of the planet, American automobiles emissions are excessively high. With only five percent of the world's population and thirty percent of the world's automobiles, the United States put in forty eight percent of the world's automotive CO2 emissions.
Any true effort to battle global warming has to include cutting automobile emissions. Acting now is crucial to slowing global warming and reducing air pollution.
Americans don't all have to drive hybrids to make a change in our nation. And, while we support everyone to use different forms of transportation whenever it is possible, the certainty is that cars are a big part of our American ways of life.

We should be thinking to:
• Put public pressure on the automobile industry to maintain a comprehensive national global warming policy.
• Educate vehicle owners and drivers on what they can do to decrease emissions.
• Explore ways we Americans can do our part to progress fuel efficiency and cut global warming pollution from America's automobiles.
So, if we all did our part to decrease automobile emissions and if all of us purchased the most fuel efficient vehicles that met our needs, and if all of us found ways to drive a less, if all of us did our best to keep our vehicles maintained, and if all of us contributed in prioritizing global warming as a issue in our daily lives, we would considerably decrease global warming pollution from America's vehicles.

Second Cause of Global Warming

Chlorofluorocarbons were introduced to the world in the 1920s and are used in a range of industrial, commercial, and residential uses and is a big part of Global Warming. Chlorofluorocarbons, along with others like chlorine- and bromine-containing compounds, have been implicated in the boost of reduction of ozone in our planet’s stratosphere. This stuff is non-flammable, non-toxic, and non-reactive with other chemical composites. These nice safety characteristics make them useful as coolants in air conditioners and refrigerators, propellants for aerosol sprays, and blowing agents. Production and use of Chlorofluorocarbons increased as a demand by us humans for production of these common products.
It was not until 1973 that chlorine was found to be a catalytic agent in ozone devastation. Catalytic obliteration of ozone gets rid of the odd O2 species while leaving chlorine unchanged. We knew that this was potentially damaging to the ozone layer, but beyond question evidence of stratospheric ozone depletion was not exposed until 1984. An intricate situation of atmospheric dynamics, chemical reactions, and solar radiation, was found to explain the abnormal low levels of ozone during the polar springtime. Current missions to the Arctic areas show that related processes can occur in the northern hemisphere, but to a lesser level due to warmer temperatures. We as a nation have to do something soon before this climate change takes a real toll on our planet!
