    Evidences of Global Warming
    a. This graph below shows the record of global average temperatures as compiled by the Hadley Centre for Climate Prediction and Research of the UK Meteorological Office.

    b. More Frequent Extreme Weather
    The year 1999 was the fifth-warmest year on record since the mid-1800's; 1998 being the warmest year. According to Thomas Karl, director of the National Climatic Data Center (NOAA), the current pace of temperature rise is "consistent with a rate of 5.4 to 6.3 degrees Fahrenheit per century." By comparison, the world has warmed by 5 to 9 degrees Fahrenheit since the depths of the last ice age, 18,000 to 20,000 ...

    Solution Summary

    The world has warmed by 5 to 9 degrees Fahrenheit since the depths of the last ice age, 18,000 to 20,000 years ago. Heating from increased greenhouse gases enhances the hydrological cycle and increases the risk for stronger, longer-lasting or more intense droughts, and heavier rainfall events and flooding. Evidence, although circumstantial, is widespread across the globe and often manifested in the form of frequent changes in climate, disappearing galciers, extinction of species etc.
