Human activities contribute far more greenhouse gases than volcanoes. The 1991 pinatubo eruption cooled the Earth for a few years afterwards...
After thinking about this more I have decided that the question is at fault as it assumes a definable point at which a non-chicken became a...
Now that I think about it I think the whole idea of a point at which non-chicken becomes a chicken is the problem. Afterall humans invented the...
A non-chicken creature that laid it
What a chicken is, is subjective and entirely defined by man. There are no strict genetic rules or definite boundaries on what constitutes a...
A few hundred years ago I could imagine US citizens with firearms would be able to prevent a military dictatorship. Back then the military under...
Because if any gas is present in the atmosphere long enough it will disperse evenly. They cite the scientific literature, which is about as...
Many greenhouse gases such as CO2 are well-mixed gases meaning that they are evenly distributed. Their high residence time in the atmosphere is...

It's pointless. Today we are emitting about 27 billion tons of co2 a year into the atmosphere. Ten years ago we were only emitting about 23.5...
But that has nothing to do with global warming. I am saying that the existing rate of co2 emissions is causing a warming, and co2 emissions are...
Nice ideas but I suspect their impact is so small that it will not really put a dent in the upward trend of emissions. Policies like Kyoto and...
Fine if you are going to define speculation as something with such high certainty then I agree - all theories in science - from atomic theory, to...
It isn't a proof - its a criteria for falsification. Scientific theories cannot be proven full stop. Atomic theory will always be a theory, the...
So what is the experiment which shows the dinosaurs used to exist? Or is this not scientific knowledge? Evolution is a scientific theory, like...
Well one prediction from the theory of evolution which I have mentioned before is that we shouldn't find mammal fossils in the cambrian. Such a...
It's more likely that you don't understand what I mean by "data point". A data point is any qualative or quantative observation of the natural...
Yes that was the assumption. For example people who hear the argument that evolution violates the 2nd law of thermodynamics, and simply repeat...
It was believed to be a few centuries back, you know when lighting seemed to complex to possibly have a natural cause. So ironic that you are...
