Just noticed the new post correcting my previous one. I take exception to people who hold up "science" as being the end-all-be-all of the universe. Someone who is a true scientist should be constantly questioning what they "know" as truth. After all, at one time we "knew" that not only was the Earth the center of the universe, it was flat. And you could fall off the edge. And thar be dragons down there.
My point is that a real scientist doesn't get mad or annoyed when their theories (or hypothesis's) are called into question, but are just as excited to be wrong as to be right.
Your argument is the same argument "scientists" use when they claim there is a consensus on "Global Warming". (Which reminds me; didn't a bunch of those morons almost get killed when the ship they took to the North Pole to look at the "melting" cap, struck an iceberg? And how about the lower yield of the Strawberry crop in Finland this year, due to lower temperatures? How about the long winter we had in the States this year? And the relatively low temperatures world-wide, lower than the average? Oh, right, consensus. Move along then.
I'll take this a step at a time.
1: science is the best tool we have. Science is the proposition of an idea, the testing of that idea, and the refinesment of it. Please suggest a course of action that would come up with better results, and I'm pretty sure enough scientists would try it and we'd find out.
2: "what we know" is based on observation and testing. You do this every day. If your coffee comes out hot, you eventually realize that machine is set to make hot coffee and you accept that as a reality. Bringing up things that people used to think were wrong only shows the strengths of science. The specific examples you used show how scientific thought triumphed over religious dogma and gave us a more realistic picture of reality. Science gave us a better truth. Scientific thought overcame the failure of religion to adequately provide for humanity. If scientific thought had been banned, you'd be scalding yourself on your morning coffee with no idea what to do but pray about it and hope it gets better.
3: Global Warming. Not everywhere will get warmer. Sometimes the effect is drier or wetter, warmer or colder, in specific locales. But the overall effect is because of heating in our atmosphere. Seasonal variance can disguise it, which is why you sometimes see cooling trends even though global warming is accelerating.
3A: Scientists and iceberg crash. I didn't bother looking this up. Let's give you this one and assume the story actually happened. All it proves is that ... there is still ice in the arctic? If anything, warming causing more and larger icebergs to shear off and threaten shipping supports the theory of global warming.
3B: consensus. There is a scientific consensus on this issue. If you look carefully at which studies were funded by people with an interest in lying to us, and take them less seriously, there isn't a debate on whether global warming is happening.
Finally, I take exception to use of humor, in the style of a spam email, to make a vapid point that is not supported by anything. Example:
Email reads "Scientists researching global warming get lost in the snow"
Hick laughs "hur hur stupid science, what has science ever done for me?"
I see this ALL THE TIME and it's crazy. It's just like political statements like "we want freedom" or "we care about our communities". Someone will say that, and because it rolls off the tongue easily and is easy on the ears, we just accept it and whatever else goes with it.
