Yes it has to be replicate and not but of scientist sitting around say yea the earth is warming....we know it's warming from records in the last 150 years. Climate models do not prove CO2 is the cause....they are not reliable

You obviously didn't read what replied to Antman below....

because we have amateur scientists on this site that say science is consensus of other scientist.... and i say no it's not....Consensus is Not Science
The late Michael Crichton, MD, author, film producer, put it this way:

“I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had.

“Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world. In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus.

“In addition, let me remind you that the track record of the consensus is nothing to be proud of”

@1patriot I understand now. Thank you. Also, I have enjoyed many great books of Michael Crichton
