Warmer climate.Melting of the polar ice caps.

Rising sea levels. Intensified droughts and heat

waves.

More and stronger hurricanes. Spread of disease. Economic damages.

Habitation destruction.

Our objective is to prove that globalwarming is real beyond any argumentsthat skeptics may come up with.

To win this case, we have to look into whatskeptics are claiming for the warmerclimate.

Let’s play devil’s advocate.

CO2 is not a pollutant. In fact, it is

necessary for life to be sustained onEarth.

Water vapor is the most prevalentgreenhouse gas, not CO2.

There are at least 33 occurrences of receding of ice shelves in history.

The bill states that it will cut emissions by 20%by 2020.

There is no solid evidence that global warmingis occurring.

The Senate is trying to predict an outcome thatis not truly foreseeable in the future.

America was built on industry and factories,but this bill will try to neutralize these assets.

Hoax!Hoax!



Why should we believe that theworld is going to end because of greenhouse gases and decayingozone layer?

There is no real evidence; these

changes were not noted in earliertimes.

Is it happening? Yes.All effects of global warming are

proven and supported by research.We can all feel the heat.

280,000 square miles of ice disappeared in ayear.

From 1958-1976, the average thickness of icewas 10 feet.

Now, the ice is less than 4 feet. Increased methane release in the air. In 2007, the Arctic ice was at its 30 year low.

Average air temperature has increased 1.1°Fover the century.

If carbon emission aren’t reduced, average airtemperature can increase 3-10°F.

Starts the domino effect.

Warmer temperatures cause ice to melt. Sea level has risen about 20 mm since the

1800s. Sea level rises 3 mm/year.

Ocean continues to become warmer andovercome cooler waters.

In 2003, more than 20,000 people in Europeand 1,500 people died of heat waves.

Warmer temperatures allow animals, insects,

and microbes to thrive in once-cold areas.

In 2000, climate change caused over 150,000deaths in the world.

Hurricanes and tropical storms get energyfrom warm water.

Ex. Hurricane Katrina.

Research shows that by 2050, ¼ of allspecies will become extinct.

In 1998, the species Golden Toad was

driven into extinction by globalwarming. Destroying coral reefs by suffocating

the algae. Birds will head to cooler climates.

Global warming is a very real danger toour way of life as we know it. Every day weget closer to reaching a disaster caused bythe steadily increasing warming of the

atmosphere. There may be no absolutelyconclusive evidence that right-out silencesthe skeptics, but there is enough conclusiveevidence in favor of the argument FOR

Global Warming.
