Scientific Journal Nature Finds Nothing Notable In CRU Leak

eldavojohn writes with an update to the CRU email leak story we've been following for the past two weeks. The peer-reviewed scientific journal Nature has published an article saying the emails do not demonstrate any sort of "scientific conspiracy," and that the journal doesn't intend to investigate earlier papers from CRU researchers without "substantive reasons for concern." The article notes, "Whatever the e-mail authors may have said to one another in (supposed) privacy, however, what matters is how they acted. And the fact is that, in the end, neither they nor the IPCC suppressed anything: when the assessment report was published in 2007 it referenced and discussed both papers." Reader lacaprup points out related news that a global warming skeptic plans to sue NASA under the Freedom of Information Act for failing to deliver climate data and correspondence of their own, which he thinks will be "highly damaging." Meanwhile, a United Nations panel will be conducting its own investigation of the CRU emails.

      The researchers did not use certain tree ring data post 1960 because it was not properly calibrated to instrumental data. There has been much hoo-hah about this "throwing out" of data when really it is the instrumental data that matters, not the proxy data. If temperature is what you are after, thermometers are the gold standard. Therefore the post 1960 results really aren't in question. Furthermore, many critics of Mann et al. have ignored the fact that this was a single line of data turning a blind eye to the numerous other data sets and proxies that support the same conclusions. I find it disingenuous to claim that all climatology is now in question due to this "trick". I will, however, admit that the researchers should have noted the issues with the tree-ring data in question.

      If one completely ignores any of the above data sets (whether they be direct measurements or proxies), there exist many disparate observations of global warming ranging from the rise in sea level which threatens various nations' lands to the melting of the arctic tundra to the loss of glaciation document global warming independently of these scientists' data. All the data seem to indicate is that the warming is happening on a scale that it has not before. By itself, this should indicate that the hockey stick curve is real. But is this warming due to humans?

      Anthropogenic global warming (AGW) critics seem to espouse ideas such as the solar cycle hypothesis or Milankovich hypothesis rather than admit that humans can change the atmosphere. On the BBC this morning I even heard a listener letter that explained how volcanoes were the cause of the increased CO2 in the atmosphere. This ignores some of the more obvious ways in which humans can change the atmosphere. This year, the Chinese government limited fossil fuel burning before the Olympics with apparently stunning results. When I was in Beijing for nearly a month 10 years ago, smog was a daily occurance. Even miles outside the city at Badaling (the Great Wall), it was hard to see for more than a mile. Smog is considered to be the third most important greenhouse gas by the IPCC.

      Nice try. The tree ring data was used as a proxy for temperature. The results of this proxy formula didn't match up with actual temperature readings past 1960, so to make their method look like it had more skill (accuracy) than it did, they simply grafted the actual temperature series to the end of the tree ring proxy temperature series. This is what was meant by "hide the decline".

      A real scientist would have investigated why the proxy failed to to reflect actual temperatures in recent times, and might have questioned if the methodology actually applied correctly to any time in the past. Instead, they grafted apples to oranges and then told everyone they had discovered something that they had not.

      Right, so the reasonable inference would be "this proxy can't event match the temperatures we know for sure -- it's no good, throw it out entirely". However, the scientists in question are so attached to their preordained conclusions that they don't even consider this. Instead, they throw out the data they don't like, and keep what matches the conclusion they want, instead of (at least *considering*) re-evaluating the conclusion to begin with.

      So they act like the proxy's correct precisely when they have less substantiation, and its failure to match the most solid data is just a problem they need to patch up later -- the so called "divergence problem". It should be called the, "Do we ever consider we might be wrong?" problem.

      It is true that water vapor is the strongest greenhouse gas. However, that's certainly not the entire story. It is also true that it is carbon dioxide that is upsetting the balance in the Earth's ability to regulate itself. As humans pump more and more carbon dioxide into the atmosphere while simultaneously cutting down huge swaths of forest (and thereby harming the Earth's ability to scrub carbon dioxide), the Earth's ability to cool itself is significantly reduced. As this process accelerates, the ice caps melt, releasing more water vapor into the atmosphere via evaporation, further compounding the effect caused by unregulated carbon dioxide emissions.

      This all adds up to an accelerating snowball effect that by the end of the century could see average global temperatures increase by six degrees Celsius. That means no more year-round snow and ice on the polar ice caps, sea levels meters above "normal" and a whole host of problems for flora and fauna (us) alike. The science is in, and the denialists are endagering us all.

      This is a classic case of Pascal's Wager, except that in this case it is actually a good argument. If we do nothing and anthropogenic global warming (AGW) is real, we risk the end of civilization as we know it. If we take aggressive action and AGW turns out to be hogwash, then we'll have taken long steps toward cleaning up our environment: a net positive for many reasons unrelated to AGW, including reduced loss of habitat, healthier oceans (and fisheries), and fewer pollutants in our food and water. Why some people insist that we should continue to rape our planet as we've always done seems, in this light, grossly irresponsible and short-sighted.

      I should add that AGW denialists are in the same camp as creationists because they willfully disbelieve science they do not understand so that they can rationalize closely held, pig-headed beliefs which only serve to preserve the status quo. Change is often hard and uncomfortable; even costly. But that doesn't mean we shouldn't embrace it. Read some ACTUAL science instead of letting people with an agenda spoon-feed you lies.

One of the most important of these middle men (who as far as I can tell controls significant aggregates of historical data) has been shown to engage in systemic and unscientific bias. Further, this group has significant connections to the IPCC working groups. Similar biases have been found against the other major groups (NOAA and NASA related groups in the US).

    To be blunt, here's a list of things that I think need to be done. First, all data and processes need to be made public domain. Simply put, proprietary data that can't be released to the public has no place in scientific research. It doesn't matter if industry-paid hacks attack anything they can find. If we can't duplicate the calculations, using your data and programs that went into your research, then we can't say whether you did it at all in the first place.

    Second, there needs to be some degree of separation between the politics and the science. For example, James Hansen who currently heads the NASA Goddard Institute for Space Studies (which is NASA's group for studying the climate) has engaged in a great deal of politics over the years, throwing away any pretense of objectivity. For example, he says:

    In Hansen's view, dealing with climate change allows no room for the compromises that rule the world of elected politics. "This is analagous to the issue of slavery faced by Abraham Lincoln or the issue of Nazism faced by Winston Churchill," he said. "On those kind of issues you cannot compromise. You can't say let's reduce slavery, let's find a compromise and reduce it 50% or reduce it 40%."

    Ignoring that carbon emissions can be dealt with through compromise (even in the worst cases) and hence are not like slavery or the spread of totalitarian ideologies, would a person with this sort of viewpoint "cook the books" when it comes to their science? Why not? When I see accusations of NASA data manipulation coupled with refusal to honor FOIA requests and highly ideological, crude public statements like the above of key officials, then it looks like a pattern of unscientific behavior to me. They can at least act like grownups.

    The people trying to force carbon emission reduction need to take their time. If they're right, then a little more time will simply solidify their position further, especially since there's no urgency in the matter according to current research. If they're wrong about the need to reduce human carbon emissions, then that'll help humanity collectively. For example, Hanson has been crying "wolf" since 1989. Even if the science is determined now (I still don't believe we've shown that human activity has a significant global warming effect), it wasn't then.

    Finally, there needs to be a genuine cost/benefit analysis of the possible choices, including various geoengineering options and procrastination. It doesn't have to be perfect, but I'm tired of the nebulous claims of disaster made by anthropic global warming proponents (Hanson in the linked story above claims "tens of meters" of sea level rise, but doesn't bother to say over what time period this rise occurs).
