This is a huge victory for honesty and ethics in science.

“will keep them [papers with differing conclusions]

out somehow — even if we have to redefine what the peer-review literature is!”

“Overall, there is the danger that the paper is used by unscrupulous people to create confusion or to discredit climate or sea-level science. Hence, I suggest that the author reconsiders the essence of its contribution to the scientific debate on climate and sea-level science.”

There is no question temperatures are significantly warmer today than they were 100 years ago or even 40 years ago.

Sea level will continue to rise (if temperatures continue to rise). That will, over decades, eventually flood low-lying coastal areas and will worsen the storm surge from major storms.

While warming eventually may be a (net) plus as parts of Canada and Russia open for farming, there will be some agricultural disruption due to changing temperature patterns.

It makes sense to move to second and third generation nuclear (along with nuclear fusion, if and when available) for power generation. That will lessen emissions of greenhouse gas while allowing inexpensive energy to continue to lift the poor out of poverty.

In other ways, when it makes economic sense, we should cut greenhouse gases.

So, while global warming is real and a problem, the scientific case for catastrophic global warming continues to weaken (see new paper,

ADDITION #4: 9:30p, Tuesday, 9/17: Mark Steyn, himself a victim of one of Mann's ridiculous lawsuits, chimes in. Reading Mark's column is great fun . (see new paper, here )., 1:50p Sunday:To clarify the Medieval Warm Period (MWP) issue, here are the two versions of the climate history of the last thousand years.Until the hockey stick, the MWP was generally accepted science. The HS is wrong not only because of it eliminating the warm period, it also does not show the Little Ice Age which obviously occurred. As one climate scientist was quoted as saying, " We have to get rid of the Medieval Warm Period ." The HS certainly accomplished that goal., 3:37p Monday: According to Technology News (click here ), Mann's troubles with the Canadian legal system may be just beginning. Punitive damages? Quite possible.10:40a Tuesday: New paper indicates the climate was, indeed, warmer 1000 years ago than it is today.
