If it's such a well established fact, then why must scientists fake the data? (http://mabination.com/threads/15710-Global-Warming-Alarmists-Fabricated-Data-to-Support-Theory)
Have you seen the article about the Oxford undergraduates yet?
Have you seen what I posted yet? I said before that the DATA wasn't faked. The analysis of the data, as performed by people who were not the ones who gathered the data, manipulated the numbers unfairly.
And the Oxford Undergraduate (whether or not they can be considered an authority on the matter aside) have largely supported "global extremism" and have only been against it once before this time.

There never was a meteor. The current scientific consensus is that there was a meteor. What evidence do you have that there was no meteor? (There is more evidence that there was a meteor than I could go through in several months, but you can wiki it if you don't believe me.)
The entire earth would be different if there was. The entire earth IS different. See any dinosaurs around?
Basic physics tells you that for it to wipe out all the dinosaurs it would have to touch nearly the whole earth, Basic Physics tells you what about the conditions needed to support life and the amount of change needed to be instigated by a meteor to push it off balance enough to cause mass extinctions?
and to do so there would need to be enough leftover energy from the main impact directed into the earth that it could create some sort of wave, similar to what happens when craters are formed, large enough to kill all the dinosaurs. A meteor of such power would have easily shattered the earth.
And even if the meteor itself didn't kill the dinosaurs, explain to me how it changed the climate?
On top of that, if it wiped out the dinosaurs, how the heck did everything else survive?
Aside from what I put in teal, what is the currently supported theory is that a meteor landed in the gulf of mexico. It isn't about the force of the impact. I think you have the wrong idea.
The
impact was not what caused the mass extinction (well it definitely was the cause at the impact location), the
effects of the impact was the cause.
The impact caused a lot of chemicals to be kicked up, and caused a lot of volcanoes to become active due to a sudden increase in tectonic activity. A high amount of silicates both from the meteor impact and from the volcanoes formed a layer in the upper atmosphere that reflected a lot of sunlight. Plants died, dinosaurs who ate plants died, dinosaurs who ate dinosaurs who ate plants died. That's the currently supported model.
And about the last comment you made, not everything was dependent on a large amount of sun. Much of the sea life was fine with decreased amounts of light. Phytoplankton don't use massive amounts like plants, rather there is a massive amount of them, and they each do a little. Also, small plants like bryophytes and the small mammals that fed on them were similarly non-affected. In-fact, with a sudden decrease in competition, these kinds of life
thrived.
