Change is the only constant on Earth… from periods of extreme global cooling to warming, driven by natural factors like variations in the Earth’s orbit. Over the past 50 years scientists have recorded environmental data which point the blame on mankind’s actions, inaction, and delayed reaction. Earth’s surface temperature increased by 1.1to1.6 degrees Fahrenheit between 1906 and 2005. Though the increments may not seem alarming, it is the rate of temperature change that’s especially troubling to scientists. Temperatures have risen nearly twice as fast in the last 50 years over both land and sea.
