There actually was an ice age. The earth is warmer now. The Earth is changing, evolving, and these changes will continue until the Earth no longer exists. And even that end is coming.
But, alas, Global Warming, while a genuine concern, is hardly science. While there are anomalies that have occurred over the last 75 years they indicate absolutely nothing. Serious, credible and fully accredited scientists do not believe that global warming is happening at all. Moreover they are absolutely POSITIVE that the anomalies often cited by Global Warming Zealots are not even remotely man made.
James Delingpole has written an excellent report titled "Earth is Safe From 'Global Warming' Say The Men Who Put a Man on the Moon." Citing over 40 scientists, Astronauts and ex-NASA employees who have formed The Right Climate Stuff Research Team Delingpole reports:
The planet is not in danger of catastrophic man made global warming. Even if we burn all the world's recoverable fossil fuels it will still only result in a temperature rise of less than 1.2 degrees C.
It's not necessary for you agree with they ex-NASA scientists. But you must not deny that there is serious and legitimate debate.
Political footballs do not science make.
The bottom line is not to deny climate change, but to carefully study it further and stop the hysteria that leads to political warfare, false fund raising, political posturing and the efforts to ban and censor anyone who dares to disagree with the Zealot's Warming Alarmist Creed.
