1: Global Warming has become the most talked of topic in the news over the years. It is the result of adding too much carbon dioxide to the air. Between 1961 and 1967, the glaciers lost 890 cubic miles of ice. The average temperature has changed 1.4 degrees Fahrenheit since 1880. By the year 2040, scientists think we will have an ice free year if Global Warming doesn't stop.
2: To many people in our world today, Global Warming isn't the main priority. Several argue that Global Warming is a minor issue as opposed to major issues such as AIDS or HIV. Other factors contribute to the damage of our ozone layer, they argue. It's not human activities and carbon dioxide causing this, they say. "If you look at the long term records, the Arctic has been warm or warmer than it is today," exclaims John Christy, a climate expert. Countless arguments have been aimed to not the factors of Global Warming, but the scientists themselves. Numerous citizens, including the science magazine, ScienceAAAS.com, have been arguing that scientists have been wrong before, their predictions have been false several times, and that maybe they made an error in their calculations or had drawn incorrect conclusions on available evidence. "Physicists tend to be super-critical of strong conclusions, but the data on global warming now indicate the conclusions are not nearly strong enough," Leon M. Lederman. | Argument For People Against Global Warming
4: On the other side of the agreement, scientists do believe that humans are causing Global Warming. In fact, 97% of climate experts agree that humans are the issue. They say that pollution is increasing by using cars, trucks, or running factories. This is a sign of using the greenhouse effect too much. The greenhouse effect is the result of water vapor, carbon dioxide, and other gases trapping energy, which results in the earth being warmer than usual. A climate expert at sciencemag.org quoted, “Human activities are modifying the concentration of atmospheric constituents that absorb or scatter radiant energy. [M]ost of the observed warming over the last 50 years is likely to have been due to the increase in greenhouse gas concentrations.” American citizens can also see the evidence left behind by global warming. For example, glaciers melting, extreme drought in some countries, and flooding in other places. Also, more trees are being cut down for homes. Trees actually help our evironment. They collect carbon dioxide, which is the harmful gas. Even some of our favorite animals are dying; the polar bear and penguins. Pamela A. Matson at Standford University quoted,” Evidence is mounting from many different scientific disciplines that Earth’s natural systems are already undergoing rapid change. We need to act now to reduce heat-trapping gas emissions, for the sake of our children and the other species with whom we share this planet.”
