History shows that a warmer world is better on several accounts.

• CO₂ is like plant food and most plants evolved at times when CO₂ levels were much higher than today. Laboratory results show that plants grow bigger and faster with increased levels of CO₂.

• This boost in agricultural productivity reduces hunger and the illnesses that inadequate nutrition help produce.

• In addition, weather patterns are generally more stable with fewer catastrophic weather events, and warm weather produces far fewer deaths than cold weather.

• These factors contribute to longer average life spans and increased human populations during climactic warm periods compared to cooler times.
