For those saying taking action before something happens is sloppy... Do you have PFDs, VHF, Radar, or EPIRB on your boat? If so, why? Are you expecting something, like sinking or getting into some trouble in the middle of the ocean? Tsk tsk tsk...
Ordovician era was when the world was covered by the oceans, wasn't an ice age... Algeas were the photosynthesis source and oh yeah almost forgot, we would survive on 4400ppm... The land wasn't there yet...(450million years ago, which is way before beginning of the time for some

)
Kyoto requieres %5.2 drop on emissions... Not an economic suicide...
Lead was used as cavity filler, was in the gasoline and paint, and then all of a sudden we are trying to avoid lead even in fish we eat!!! Somebody saw it coming...
The fish we catch on our shores have health warning about consuming limits! What happened here? It's that good old fish...
The scientific community needs that funding for proving their points...
Apparently no one touched the Carbon tracker? What's wrong guys?
Earth does go through cycles but;
"As noted above, the ocean, which covers 71% of Earth’s surface, has been one of the principal sinks for anthropogenic CO2. If one were to examine its “heat content,” the role of the ocean becomes even more significant: approximately 84% of the heat energy associated with global warming resides in the ocean. This observation can be explained by the large heat capacity of liquid water to store energy compared to the atmosphere and biosphere. Over the past 50 years, ocean heat content has been observed to increase even to depths of 1000 meters. The ability of the ocean to absorb both heat and CO2 is enhanced by its ability to sequester them over a kilometer-thick layer. But future changes are expected to lead to reduced oceanic mitigation due to both increased water temperature (less ability to absorb gasses like CO2) and a more limited depth range for heat storage. A reduction in the depth of oceanic heat storage by a factor of two will result in a doubling of the climate sensitivity to CO2 increase and thus a doubling of the expected future global temperature increase."

"
In the absence of human influences, the amount of CO2 in Earth’s atmosphere is controlled by the balance between sources and sinks for CO2, much like the amount of money in your bank account is controlled by how much you put in and how much you take out. The primary source for CO2 on geologic time scales is volcanism and outgassing from the mantle, deep within the Earth. Erosion of oil-rich, or petroleum-rich, rocks has also contributed to the amount of CO2 in the atmosphere in the past. The sink for CO2, on geologic time scales, is the erosion of silicate rocks. Silicates are the type of rock that makes up mountains. So the erosion of mountains reduces CO2 in the atmosphere; volcanism and exposure of hydrocarbon-bearing strata increase CO2 in the atmosphere.
Concentrations of greenhouse gasses like CO2 and methane are higher now than any time in the past 600,000 years, and are projected to increase even more (Fig. 1). Initially, CO2 concentrations in the atmosphere were projected to double (Fig. 1) over the next 100 years. But we may be on a fast track where a quadrupling is not inconceivable. At that point in time, we would be living in a greenhouse atmosphere much like that of the mid-Cretaceous, 90 to 100 million years ago, when dinosaurs (
and not humans) ruled the earth."
We are releasing the carbon from the depths where it's been trapped and that's what changing the balance...
And yes, we don't have flaggers in front of the cars but we have traffic regulations, signals and safety cautions... Ironically, Germany has a really low death rate by traffic accidents versus US, yet has higher or no speed limits!!! Why? Because, it takes 3 years to EARN your licence there, not one afternoon!!! Education and training makes the difference!
Even China seems to be the biggest emissions provider, it's actually the USA... Number one in something we should be ashamed of... If you are OK with running your car in your garage when your children in there, I have nothing to say...
And US doesn't have much dependency on fossil fuel, if only the consumers ask for better options! The technology is here, just ask for it... Example, how many of US consumers are expecting Laser TVs in 2008? The rest of the world is... How come the European and Asian cars are offering the newest technology, meanwhile the American auto industry is still trying to sell me a car that's outdated?
