If global warming is a fact, how do you explain these? Scientist: Forget Global Warming, Prepare for New Ice Age "This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," Chapman wrote in The Australian Wednesday. "If the temperature does not soon recover, we will have to conclude that global warming is over." --------------------------------------------------------- ---------------- http://www.foxnews.com/story/0,2933,352241,00.h tml ------------------------------------------------------------ ------------- Forget global warming: Welcome to the new Ice Age Snow cover over North America and much of Siberia, Mongolia and China is greater than at any time since 1966. The U.S. National Climatic Data Center (NCDC) reported that many American cities and towns suffered record cold temperatures in January and early February. According to the NCDC, the average temperature in January "was -0.3 F ...more

The green house gases like carbon dioxide, methane, and nitrous oxide are playing hazards in the present times. These green house gases trap heat in earths atmosphere and thus result in increasing the temperature of earth. The excessive emission of these gases is one of the major Causes of Global Warming. Manking is responsible for this and all the changes directly or indirectly affect them. Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. As a further effect of global warming, diseases like malaria are returning into areas where they have been extinguished earlier.

The earth is about 60 degrees Fahrenheit (33 degrees Celsius) warmer than it would be if it did not have the atmospheric blanket of greenhouse gases and clouds around it. Clouds and greenhouse gases keep the earth warm. Once warmed, their molecules then radiate a portion of this heat energy back to earth, creating more warming on the surface of our planet. It is this radiation which causes atmospheric gases to move back to earth that scientists call the "greenhouse effect". The global effects of the greenhouse effect cannot be directly predicted simply because we do not have enough knowledge in the subject. However, we have been able to draw direct connections between certain natural phenomenon that supports the idea that something is changing. Global warming has great effect on crops and weather conditions around the world. The northern hemisphere contains more land area than the southern hemisphere, and conversely, a lower percentage of the world's oceans. Since oceans ...more

Devastation of natural resources. Changing of the hot or cool currents near the oceans results in developing low pressure points that later become hurricanes or tornedos. Rise in temperature affects biota of cooler countries. Melting of ice at the polar regions will bump up ocean levels, so floods will be common. In all spheres, global warming is detrimental to our survival.
