Richard Harris. A seven-year drought and increased water demand spurred by climate change and explosive population growth in the Southwest has caused the water level at Lake Mead, which supplies water to Las Vegas, Arizona and Southern California, to drop more than feet to its lowest level since the s. As carbon dioxide emissions continue to rise, the world will experience more and more long-term environmental disruption. The damage will persist even when, and if, emissions are brought under control, says study author Susan Solomon, who is among the world's top climate scientists.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases i. Part of this radiation is directed towards the surface, thus warming it. The temperature rises until the intensity of upward radiation from the surface, thus cooling it, balances the downward flow of energy. Earth's natural greenhouse effect is critical to supporting life and initially was a precursor to life moving out of the ocean onto land. Human activities, mainly the burning of fossil fuels and clearcutting of forests, have increased the greenhouse effect and caused global warming. The term greenhouse effect is a slight misnomer , in the sense that physical greenhouses warm via a different mechanism.
Fact or Fiction?: We Can Push the Planet into a Runaway Greenhouse Apocalypse
Jump to navigation. The greenhouse effect is a good thing. It warms the planet to its comfortable average of 59 degrees Fahrenheit 15 degrees Celsius and keeps life on earth, well, livable. Without it the world would be a frozen, uninhabitable place, more like Mars. The result?
Use the controls in the far right panel to increase or decrease the number of terms automatically displayed or to completely turn that feature off. The 2nd law of thermodynamics is consistent with the greenhouse effect which is directly observed. According to the second law of thermodynamics such a planetary machine can never exist.
