What's Really Warming the World? Climate deniers blame natural factors; NASA data proves otherwise. Climate scientists tend not to report climate results in whole temperatures. Instead, they talk about how the annual temperature departs from an average, or baseline. They call these departures "anomalies. " They do this because temperature anomalies are more consistent in an area than absolute temperatures are. For example, the absolute temperature atop the Empire State Building may be different by several degrees than the absolute temperature at New York’s LaGuardia Airport.

But the differences from their own averages are likely to be about the same. The simulation results are aligned to the observations using the 1880-1910 average. Are global co2 emissions still rising? Virtual Water - Discover how much WATER we EAT everyday. The good news is that each one of us can also make the world a little more water secure, ready to face the needs of our peak population future.

7 Billion: How Did We Get So Big So Fast? Watch as global population explodes from 300 million to 7 billion. Sometime Monday, the world will have more humans than ever: 7 billion, according to the U.N. The U.N. estimates that the world's population will pass the 7 billion mark on Monday. Much of that growth has happened in Asia — in India and China. Due in part to that region's extreme poverty, infant mortality rates are high and access to family planning is low. As NPR's Adam Cole reports, it was just over two centuries ago that the global population was 1 billion — in 1804. As higher standards of living and better health care are reaching more parts of the world, the rates of fertility — and population growth — have started to slow down, though the population will continue to grow for the foreseeable future.

U.N. forecasts suggest the world population could hit a peak of 10.1 billion by 2100 before beginning to decline.
