Absolute proof of Global Warming found right here.
Of course, it happened before man's input:
The Torres Strait itself was formerly a land bridge which connected the present-day Australian continent with New Guinea (in a single landmass called Sahul or Australia-New Guinea). This land bridge was most recently submerged by rising sea levels at the termination of the last ice age glaciation (approximately 12,000 years ago), forming the Strait which now connects the Arafura and Coral seas. Many of the western Torres Strait Islands are actually the remaining peaks of this land bridge which were not submerged when the ocean levels rose.I guess more proof is from the lack of a glacier sitting outside my window.
More on Ice Ages here. And here:
During the present ice age, glaciers have advanced and retreated over 20 times, often blanketing North America with ice. Our climate today is actually a warm interval between these many periods of glaciation. The most recent period of glaciation, which many people think of as the "Ice Age", was at its height approximately 20,000 years ago.Oh, yeah, and there is also evidence of prior "Global Warming":
Although the exact causes for ice ages, and the glacial cycles within them, have not been proven, they are most likely the result of a complicated dynamic interaction between such things as solar output, distance of the Earth from the sun, position and height of the continents, ocean circulation, and the composition of the atmosphere.
Between 52 and 57 million years ago, the Earth was relatively warm. Tropical conditions actually extended all the way into the mid-latitudes (around northern Spain or the central United States for example), polar regions experienced temperate climates, and the difference in temperature between the equator and pole was much smaller than it is today. Indeed it was so warm that trees grew in both the Arctic and Antarctic, and alligators lived in Ellesmere Island at 78 degrees North.UPDATE: Another thing affecting life on our planet:
The seismic jolt that unleashed the deadly Solomons tsunami this week lifted an entire island metres out of the sea, destroying some of the world's most pristine coral reefs.
In an instant, the grinding of the Earth's tectonic plates in the 8.0 magnitude earthquake Monday forced the island of Ranongga up three metres (10 foot).
Submerged reefs that once attracted scuba divers from around the globe lie exposed and dying after the quake raised the mountainous landmass, which is 32-kilometres (20-miles) long and 8-kilometres (5-miles) wide.
Corals that used to form an underwater wonderland of iridescent blues, greens and reds now bleach under the sun, transforming into a barren moonscape surrounding the island.
The stench of rotting fish and other marine life stranded on the reefs when the seas receded is overwhelming and the once vibrant coral is dry and crunches underfoot.
