**Is Global Warming A Problem?**

 * What Scientists Agree On:**

"Scientists do agree that: 1) global average temperature is about 0.6°Celsius—or just over 1° Fahrenheit—higher than it was a century ago; 2) atmospheric levels of carbon dioxide (CO2 ) have risen by about 30 percent over the past 200 years; and 3) carbon dioxide, like water vapor, is a greenhouse gas whose increase is likely to warm the Earth’s atmosphere." ([|http://www.globalwarming.org/primer/scienceFAQs)]


 * What Scientists Don't Know Yet:**

"Scientists do not agree on whether: 1) we know enough to ascribe past temperature changes to carbon dioxide levels; 2) we have enough data to confidently predict future temperature levels; and 3) at what level temperature change might be more damaging than beneficial to life on Earth."
