Five Climate Questions for Richard Muller (Temperature findings begin, not end, the real debate): Q1: How has the global average temperature changed in recent history?
Q2: How much of that change is attributable to human activities, and how much to a given activity? Q3: What can we expect to happen to the climate in the future? Q4: How will those predicted changes affect people in the future? Q5: What should we do today in response to Q1–Q4?
