2005 was the hottest year on record
(tied with 1998), according to NASA.
There has been a 100% Increase in intensity and duration
of hurricanes and tropical storms since the 1970's, according to a 2005 MIT study.
$100 billion was the estimated cost of damage caused by
hurricanes hitting the U.S. coast in 2005 alone, according to the National Climatic Data Center.
By 2030 Glacier National Park will have no glaciers left, according to the U.S. Geological Survey predictions.
400, 000 square miles of Arctic sea ice have melted in the last 30 years (roughly the size of Texas), threatening polar bear habitats and further accelerating global warming worldwide, according to the Arctic Climate Impact Assessment.
15% - 37% of plant and animal species could be wiped out by global warming by 2050.
The United States is ranked number one as a global warming polluter
compared to other large nations.
6 former U.S. Environmental Protection Agency leaders say the U.S. is not doing enough to fight global warming.
Global warming facts and statistics
At the rate our climate is changing, the world will soon be warmer than at any time in th last 10,000 years.
The world has warmed by 0.5 degC over the past century and an average 2 degC warming is predicted by 2100.
There is scientific consensus that air pollution from human activities is partly responsible for global warming.
Climatic changes will alter natural vegetation, wildlife habitats, crop growing seasons, and distribution of pests and diseases.
Global warming will cause a continued and accelerated rise in sea levels, threatening half of the world's most critical coastal wetlands.
A one-meter rise in sea level would threaten half of the world's coastal wetlands of international importance for their biodiversity.
A 3 degC to 4 degC warming could eliminate up to 85% of the remaining wetlands in the semi-arid regions of southern Europe.
The loss of wetlands in the flood plains of rivers in the African Sahel could make some local populations of turtles and birds extinct.
A 3 degC to 4 degC warming could eliminate all open waters of the prairie pothole region in the US, an area where half of the wild duck population hatch out.
About 30 new infectious diseases have emerged in the past 20 years.
Global warming will expose millions of people to new health risks. Infectious diseases are emerging, resurging and undergoing redistribution on a global scale.
Global sea level has risen between 10 to 25 cm in the last 100 years and will rise faster still in the coming decades.
By the year 2050, up to one million additional deaths from malaria may be occurring annually as a result of climate change.
The arctic is unusually important for migratory birds. An estimated 15% of the world's bird species are arctic specialists. In north america, 36 species breed only above 60 degN latitude.
Ringed seals are the principal prey of polar bears. Unseasonal warming can lead to collapses of the snow caves where female seals bear their young. The young as yet have no blubber and die of exposure when cold conditions return. Scientists suspect that declines in seal populations will occur in this manner, and will ultimately lead to declines in polar bear populations.
Detailed climate models suggest that a doubling of greenhouse gas concentrations will lead to a 30% reduction in the tundra available to Arctic species.
Many of the world's most distinctive mammals are found only in the Arctic, including walrus, several species of seals, arctic foxes, collared lemmings, arctic and tundra hares, muskoxen, polar bears, mmarwhals and bowhead whales.
As sea ice becomes thinner due to increased temperatures, animal intruders from the south, such as grizzly bears and moose, are penetrating north affecting local populations.
Between 15 to 20% of the large nature reserves in southern reserves in southern Africa would experience a change in biome or habitat type under different climate change scenarios.
Climatic changes will alter natural vegetation, wildlife habitats, crop growing seasons, and the distribution of pests and diseases.
