3 As the world warms
3.1 Warming
3.1.1 More water vapor in air
3.1.1.1 More rainfall, more intense weather generally
3.1.1.1.1 Heat waves more serious
3.1.1.1.1.1 1997 was the hottest
3.1.1.1.1.1.1 People have contributed to global warning
3.2 1860
3.2.1 1860 Planet was still recovering from little ice age
3.2.1.1 Presat warning might be a continues of that rebound

4 Anticipating the future
4.1 If greenhouse gas emition stop
4.1.1 Warm continues for decades
4.1.1.1 “Next 10 years will tell”
4.1.1.1.1 “We’re going to have to wait”
