GLOBAL WARMING What Is Global Warming? Global warming is the warming of the earth through carbon dioxide (CO2) being pumped into the atmosphere from tailpipes and smokestacks. Then the gases trap heat like the glass in a greenhouse. This is where the term the “greenhouse effect” came from. What’s Happening Scientists say that the barrier insulating the continental ice caps is melting. “The impacts of warming temperatures in Antarctica

In addition‚ we need to breathe air to sustain our life because clean atmosphere is a necessary condition for the survival of mankind depends on. Therefore‚ the contaminated air has a direct impact on human health. Of harmful chemicals in the atmosphere enters our body through the respiratory tract and enter our body through the digestive

harmful depending on its location in the Earth’s atmosphere. If the ozone is located in the troposphere (which extends from the surface of the Earth up to approxiametly10 miles) it is a harmful pollutant and a major component in smog and other environmental health problems. Such tropospheric ozone can damage plastic‚ rubber‚ plant and animal tissue. Ozone located approximately 10-25 miles above the Earth’s surface‚ in a part of the Earth’s atmosphere called the stratosphere is very beneficial. The

Mainstream scientific organizations concur with the assessment that most of the temperature increases since mid-20th century has been caused by growth in the atmosphere greenhouse gas concentrations produced by human activity. While there are arguments in favour of natural cause of the global warming‚ I think on balance that the arguments against carry greater weight. A common skeptic argument is that climate has changed naturally in the past‚ long before SUVs and coal-fired power plants‚ and

Volcanic eruptions also emit large amounts of gases including sulphur‚ water vapour‚ and carbon dioxide. Sulphur dioxide in the atmosphere causes the formation of acid droplets that scatter in the atmosphere and cause the sun’s rays to bounce back

This would have all been possible and happened during the archean eon. One thing this article explained well is how much of Co2 and methane combined would have kept heat trapped in the atmosphere. Just to keep earth above freezing‚ it would take about 75 times of Co2 as there
