Carbon dioxide levels are now approximately 40 percent higher than they were at the start of the Industrial Revolution, and they have reached levels not seen in the atmosphere in 20 million years. Scientists say that unless we curb greenhouse gas emissions, average U.S. temperatures could be 3 to 8 degrees Fahrenheit (2 to 4.5 degrees Celsius) warmer by the end of the century.
There continues to be uncertainty about what the exact consequences of global warming will be, but an overwhelming majority of scientists and leaders are warning that since higher global temperatures and sea levels are a virtual certainty, we cannot afford to wait to see exactly what happens. Uncertainty should not be treated as a reason to sit on our hands and hope that the problem resolves itself. Instead, we must roll up our sleeves and take steps to address this problem now.
