Continue to ignore the facts dude, and continue to be "cracked up" because it really shows...
The search for the Northwest passage started in 1400s genius...which still isn't that long ago compared to the frickin billions of years the earth has been around. The Vikings first used a form of it to trade with the Inuit tribes. Then the colonial powers attempted to find a route. It wasn't successfully navigated until the early 1900s... This still proves nothing on your side. Face it, you can't prove GW is caused by humans...and you can't prove it's CO2 |
It is proven that CO2 causes the earth to warm. Even you cannot deny that. The question is, How much has increasing the CO2 level by one third caused the earth to warm?
