Scientific progress depends on accurate and complete data. It also relies on replication. The past couple of days have uncovered some shocking revelations about the baloney practices that pass as sound science about climate change.
It was announced Thursday afternoon that computer hackers had obtained 160 megabytes of e-mails from the Climate Research Unit (CRU) at the University of East Anglia (UEA) in England. Those e-mails involved communication among many scientific researchers and policy advocates with similar ideological positions all across the world. Those purported authorities were brazenly discussing the destruction and hiding of data that did not support global-warming claims.
Professor Phil Jones, the head of the Climate Research Unit, and professor Michael E. Mann at Pennsylvania State University, who has been an important scientist in the climate debate, have come under particular scrutiny. Among his e-mails, Mr. Jones talked to Mr. Mann about the “trick of adding in the real temps to each series … to hide the decline [in temperature].”
Mr. Mann admitted that he was party to this conversation and lamely explained to the New York Times that “scientists often used the word ‘trick’ to refer to a good way to solve a problem ‘and not something secret.’ ” Though the liberal New York newspaper apparently buys this explanation, we have seen no benign explanation that justifies efforts by researchers to skew data on so-called global-warming “to hide the decline.” Given the controversies over the accuracy of Mr. Mann’s past research, it is surprising his current explanations are accepted so readily.
