A 21 page report compiled by a panel of the world's top scientists from 113 countries now say they are 90% sure that global warming is caused by humans. The report states that by the year 2100 temperatures will rise an average of 3-7 degrees Fahrenheit and sea levels will rise between 7 and 23 inches. Just think, New Orleans thought they had it bad in 2005.
I'm glad that it took the world's top scientist finally figured out that greenhouse gases such as CO2 and Methane act as an actual greenhouse. Who could have known?
No one says that the Earth doesn't gradually go through natural stages of warming and cooling. The fact is that all these warming trends happen when there is a rise in CO2 levels. As you can see from the chart below, taken from Vostok ice core samples, we are currently spewing more CO2 into the atmosphere than ever before. The logical outcome from this will inevitably result in higher temperatures as heat reflecting off the surface of the earth will be trapped by these greenhouse gases.
Anything which burns fossil fuels such as coal plants and automobiles as well as Methane from agriculture all produce extra greenhouse gases which the Earth wouldn't ordinarily generate on its own. More greenhouse gases mean more heat is trapped into the atmosphere.
For the time being, the United States is the biggest emitter of greenhouse gases; China isn't far behind.
Believe it or not, there are still plenty of people who think that emissions from cars and power plants don't generate greenhouse gases and that greenhouse gases don't trap heat into the atmosphere and that heat can melt ice caps.
But you know, when it comes to global warming you shouldn't trust scientists who stand to make billions of dollars by saying the Earth is getting warmer. Who you should trust are the people in agrigulture and the auto, coal and oil industries because they clearly have nothing to gain by saying global warming is a myth. It's kind of like those people with cancer and voice boxes who say smoking causes these conditions when the tobacco industry has had scientists on their side for years saying that smoking doesn't cause cancer. Clearly the tobacco industry had nothing to gain by stating that position.

People like Lee Raymond need more money.
I wrote about this on my blog yesterday. Someone actually responded that it wasn't real because the polar icecaps on Mars are melting, too. They claim that it's all simply because the sun is getting hotter.
But do they really think that greenhouse gases don't act as a greenhouse?? Whats not to get? I mean there could be other factors involved as well but the fact is that greenhouse gases trap the suns heat into the atmosphere and car and coal plants create more greenhouse gases now than the world has ever seen.
They don't believe that hmans have an effect on warming the earth.
If this were an issue of people not believing that the act of standing in front of large speeding trucks might cause a little physical discomfort, it wouldn't be a big thing to let them go about their business (except a little bit for the trucking industry).
When it's an issue of doing serious damage to the human race, causing the death and displacement of billions of people, because they're mindlessly subscribing to the ill-advised P.R. spin of exclusively self-interested corporations instead of the scientists who'd know, then we may need to start talking to them about the benefits of standing in front of large speeding trucks.
We'd be doing the planet a favour.
