What is Global Warming?

Answer 1

Global warming is the increase of the world's temperature due to the build-up of gases in the Earth's atmosphere, culminating from a phenomenon known as the Greenhouse effect.

Severe side-effects include the melting of the polar ice caps, which in turn causes flooding of coastal cities by tsunamis and the works. Also global warming which screws up the natural order of biomes, which in turn will cause a massive extinction rate of animals.

Go Bush and his veto of the Kyoto Treaty!

Answer 2

Global warming is appearing to be more and more of a will-o'-the-wisp.
From Wikipedia:
"In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, temperatures at the South Pole average around −25°C (−12°F). As the six-month "day" wears on and the sun gets lower, temperatures drop as well, with temperatures around sunset (late March) and sunrise (late September) being about −45°C (−49°F). In winter, the temperature remains steady at around −65°C (−85°F). The highest temperature ever recorded at the Amundsen-Scott South Pole Station is −14°C (7°F), . . ."

There is no weather observation station at the North Pole, but we can assume from symmetry and the Earth's orbit that the warmest the North pole has ever been is below −14°C (7°F).

From ONR:
"The freezing point of seawater is about 28.4°F (-2°C)"

Before there can be any melting of the polar ice caps by sea water, the pack ice must melt, and then the surrounding sea water must warm to 0°C (32°F). Air reaching the ice caps must flow over the pack ice, cooling as it goes.

Data published by NOAA, though it supports the hypothesis of a warming trend, does not support the hypothesis of an alarming warming trend. The maximum increase indicated by the trend curves applied to this data is about 2°F per century. The maximum average annual temperature calculated (55.01°F in 2006) is a mere 0.1°F above the 1934 average temperature of 54.91°F. That's an increase of 0.139°F per century.

I also find it curious that the oft quoted 15°C is exactly 59°F. Such exactitude rarely occurs in nature.

Answer 3

Global warming is the observed increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation

Answer 4

A load of B.S started by "Al Gore" the idiot ! We just had the coldest April on record in NY, where's "AL" NOW ? Weather is Cyclical, there is NO proof of Global Warming, The sky is NOT falling Chicken Little !

Answer 5

Global Warming is the gradual increase in the Earth's temperature caused my man (increase in atmospheric Carbon Dioxide) or by gradual climate change While we debate the arctic ice cap slowly melts & the polar bear faces extinction in the wild

Answer 6

Global Warming: The gradual increase of the temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the Industrial Revolution.

The temperature of the atmosphere near the earth's surface is warmed through a natural process called the greenhouse effect. Visible, shortwave light comes from the sun to the earth, passing unimpeded through a blanket of thermal, or greenhouse, gases composed largely of water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Infrared radiation reflects off the planet's surface toward space but does not easily pass through the thermal blanket. Some of it is trapped and reflected downward, keeping the planet at an average temperature suitable to life, about 60°F (16°C).

Answer 8

A farce. I believe that 1999 was the warmest year on record. If we had gw, wouldn't each year increase?

Answer 9

a load of bulls*t
