How much has the Earth Warmed? The Earth has warmed by about 1.8ºF over the past 100 to 150 years. How can a one-degree increase in the global temperature possibly gain acceptance as the source of recent weather and translate into unlikely claims about future catastrophes and the demise of polar bears?
CO 2 = LIFE CO 2 is in fact the most important airborne fertilizer in the world, and without it there would be no green plants at all. Even a doubling of CO 2 would produce a rise in plant productivity. Its terrible that millions are being wasted on a problem that doesnt exist- money that could have been used in better ways: fighting world hunger, providing clean water or creating jobs. -David Bellamy, Botany Professor -David Bellamy, Botany Professor
Global Warmers claim polar bears are being threatened by: Air Pollution Sea Level Rise Ice Caps Melting Global Temperature Rise
In the book "Cool It: the Skeptical Environmentalist's Guide to Global Warming by Bjorn Lomborg", the Danish professor states the declining population in Canada's western Hudson Bay, fell by 22% from 1194 in 1987 to 935 in 2004 and suggests the decline is due to hunting. Fifty polar bears are shot each year.
In 2005, the US Geological Survey of the Arctic Refuge Coastal plain reported there are 19 polar bear populations. Ten of them are near historic highs. Biologist Mitchell Taylor of the Arctic community, who tracks polar bears, says they are stable and thriving.
Global Warmers Al Gores Inconvenient Truth allegedly provides evidence that global warming is harmful and will cause major destruction. President Obama is committed to passing economically devastating legislation that will do little to nothing to stop global warming.
The consequences of listing the polar bear on the endangered species list will have widespread social and economic impacts without providing any more protection for the bears. - Sarah Palin, Alaska Governor
Not a week goes by without some news outlet obsessing over the devastating effects of global warming.
Global Warming Scare Tactics Threat to human health Rising SeasExtreme Weather Biodiversity Loss
HURRICANE KATRINA HURRICANE KATRINA Hurricane Katrina was just one of a series of devastating hurricanes in 2005, and the media reported non stop about how that was a glimpse of things to come if humans didnt stop driving SUVs and using air conditioners. But then we didnt hear much when there were no land-falling hurricanes in But then we didnt hear much when there were no land-falling hurricanes in 2006.
What changed in the United States with Hurricane Katrina was a feeling that we have entered a period of consequences. -AL GORE There are no scientific studies that show a conclusive link between global warming and observed hurricane frequency and intensity. -Dr. Christopher Landsea Research Meteorologist at the National Oceanic Atmospheric Administration
We live in the midst of alarms; anxiety beclouds the future; we expect some new disaster with each newspaper we read. -Abraham Lincoln
All across the world, in every kind of environment and region known to man, increasingly dangerous weather patterns and devastating storms are abruptly putting an end to the long-running debate over whether or not climate change is real. Not only is it real, it's here, and its effects are giving rise to a frighteningly new global phenomenon: the man-made natural disaster. -Barack Obama There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well- organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere. -Al Gore
For the amount of carbon and gasoline that Al Gore emits from his private jet, the average family could travel back and forth from Nashville to San Francisco in a Station Wagon 30 times, just to equal Al Gores "damage to the Planet" in one day.
"It turns out that all that data was all fabricated out of thin air by Al Gore. I am deeply ashamed for having unwittingly perpetuated such a massive fraud on the governments of the world. I suppose that we should have instituted some sort of peer-review process before publishing such alarming conclusions. "It turns out that all that data was all fabricated out of thin air by Al Gore.

How it all got started…
Al Gores Movie Inconvenient Truth Claimed: There is less ice and polar bears are drowning. Sea levels will rise 20 feet due to melting ice sheets. Four polar bears died during an Arctic storm and Gore used this as evidence that global warming was killing polar bears.
Al Gore Answers Questions
"Their habitat is melting... beautiful animals, literally being forced off the planet. They're in trouble, got nowhere else to go. -Al Gore
Polar Bears have become an Icon for Global Warming.
Al Gore and the media use photos like these to spread their propaganda to make money.

Is Global Warming affecting the Polar Bears? It is widely thought that the polar ice caps are melting, causing sea levels to rise, which will result in the loss of cities along the coast, as well as the majority of polar bears. However, a study by Dr. David Legates, director of the University of Delaware's Center for Climatic Research and state climatologist, examines the claim that global warming threatens to cause polar bear extinction and finds little basis for fear. By and large, the study finds that polar bear populations are in good shape.
Amanda Byrd, Australian marine biology student took this photo on a field trip. It was taken in August when the fringes of the Arctic are suppose to melt, regardless of global warming. They didnt appear to be in any danger..
More and more countries around the world that incorporate Arctic landscape like the United States, Russia, Canada, and Greenland, are pledging to work to preserve the polar bear populations.
According to the US National Biological Service, polar bear populations are thriving. Numbers have more than tripled since 1950.
According to fossil records, there have been polar bears on this planet for over 200,000 years. During that time period there have been many periods where temperatures were higher and Arctic ice significantly declined (far below what the UN IPCC is predicting for the next 100 years due to "global warming"). Polar Bears on Thin Ice: Not Really!
From 1920 to 1940, the Arctic temps skyrocketed, warming by 4°C in two decades... about twice as much as the current rise since 1960, and in less time, and all without the benefit of CO2 increase.
What it all means…. During the period of record 1880-present, Arctic temperatures generally: Rose for 60 years, to Fell for 25 years, to Rose for 40 years, to the present. Were higher in the 30's and 40's than they are today.
The Medieval Warming The Roman Warming The Minoan Warming And many other periods where the temperatures were higher than today.. If the ice distribution changes, polar bears move. Polar Bears have Survived:
Height: 8 to 10 feet Weight: Adult males lbs Females: lbs Lifespan: years The long neck and narrow skull of the polar bear aid in streamlining the animal in the water, and the front feet are large, flat and oar like. Studies, carried out in the Beaufort Sea, show polar bears are excellent swimmers and have been seen in open Arctic waters as far as 200 miles from land.
Sea Level Rising Rate In the past 150 years, the sea level has risen at a rate of 7 inches per century and is apparently not accelerating. -John Christy, Alabama State Climatologist, May 13th, 2003
Reasons for Sea Level Change: Presence or absence of ice caps Shape of continents Shape of the sea level floor Temperature of the Oceans Molten Rocks to the sea floor
Ice Caps are Thickening Dark green is in 2008 Bright green is in 2010
Reid Bryson: The Father Of Scientific Climatology and the Most Cited Climatologist. You can go outside and spit and have the same effect as doubling carbon dioxide. All this argument is the temperature going up or not, its absurd. Of course its going up. It has gone up since the early 1800s before the Industrial Revolution, because were coming out of the Little Ice Age, not because were putting more carbon dioxide into the air.
This warming is one of many kinds of climate change that the Earth has gone through in the past and will continue to go through in the future. 65 Million Years Ago 15,000 Years Ago Today
Climate Change The climate, just like the weather, changes. Climate has changed continually during the last 4.6 billion years, since the age of the earth. The Earth has been warming, with ups and downs since the little ice age.
70% Water 30% Land Humans live on 2% of land on earth How is 2% affecting climate of the other 98%??
Humans on earth are like a bug on a sequoia tree, the bug is very small and new in comparison to a very large and old tree.
There is scientific consensus of global warming and the harm its having on polar bears and their habitat : False The global warming we are experiencing is not natural. People are causing it and it will have devastating consequences: False Glaciers and Ice Caps are melting and are the main contributor to sea-level rise: False Global warming is causing Polar Bears to starve and drown: False Polar Bear populations won't be able to adapt to rapid climate change: False, climate change isnt rapid, its natural and comes in cycles. The facts behind Global Warming and Polar Bear Hysteria:
Global Warming Scare
Conclusion: Contrary to what is heard in the media, by Al Gore or by President Obama, there is overwhelming evidence that the warming we are experiencing is natural, with maybe a small amount contributed by mans activities. The polar bears are healthy and thriving and like humans, they will continue to grow and adapt to the environment in which they live.
