Skeptics always promote scientific advancement. Consensus leads to stagnation.
Answer this question and you will understand why I am a skeptic. I do not need a scientist or a consensus to be able to determine that which is actually happening and that which is a theory needing constant revision in order to make the facts fit the theory.
1. Why, if Carbon dioxide is constantly going up, hasn't the temperature been going up as well? (1998 was the warmest year of the past century, ten years ago, it hasn't been any warmer since.)
Bob, you ask:
"What makes the "skeptics" believable, other than your political beliefs? Do you also question evolution, relativity and quantum mechanics? You have no direct evidence of those either, only what the scientific community tells you. Why do you believe scientists about those, but not about global warming?"
I'll tell you the answer, it is actually rather simple. You see those scientific feilds of endeavor search for facts or truths. They take these truths and they try to formulate theories that help explain there place in nature and how they effect everything around them. The theories are created in response to the discoveries. The scientists in those feilds of study will be the first to tell you that there is more that they do not know then what they know. It is a feild of constant evolution in which theories are proven wrong all the time. The theories are re-formulated to fit the facts as they are presented. Then the theories are put to the test again as counter theories are presented. The opposing theories are not quashed or the scientists who support the opposing theories, ostracized. They are embraced as the part of the process of scientific advancement.
Now take Global Warming or as it has evolved into "climate change". (which is funny because everyone agrees that the climate constantly changes as a part of nature, all except the AGW proponents). AGW does not follow the path of healthy scientific progress. The AGW lobby takes facts and makes them fit their theory, or better yet they take facts and make them disappear as if they never existed. They have literally rewritten climate history to make their theories appear correct.
Example: The MWP was the universally-accepted climate history for hundreds of years before climate became a political issue, and then, long after climate had become a political issue, the MWP, which didn't fit the AGW story about "unprecedented" and therefore "dangerous" 20th century warming, was written out of the climate history in a matter of about six months. Doesn't that seem "fishy" to you?
The facts didn't dictate otherwise, the MWP just didn't fit into their agenda.
I do use terms like agenda and lobby, because the characteristics of the entire AGW movement are completely political.
When political agendas dominate science, when science is not open-ended, when it is not just an open-minded search for the truth or at least a number of competing teams trying to prove or disprove competing theories to a variety of questions, how can the scientific process not be skewed?
How many scientists are ostracized for submiting opposing theories? It's easy to see the AGW movement for what it is, just look at the actions of the people involved.
Last question: Do climate scientists know how the earth's climate system as a whole works? Could they tell us accurately what the weather is going to be like 10 years from now? They couldn't do it ten years ago. What makes you think they can now?
It's a good thing Columbus and the other explorers didn't listen to the "consensus" that the world was flat. Every major scientific organization was convinced the world was flat. How could it be that they were wrong? Could it be that they didn't have all the information, or that they didn't know enough about the world?
I rest upon the same observation. The scientist of today do not have enough information or knowledge about how the climate works for there not to be skeptics. The ranks of the skeptics are growing everyday, some of the original IPCC members are amoung them.
