Last year, controversy swirled around British climate researchers after leaked e-mails suggested that they had "cooked the books" on climate research by manipulating evidence, harassing opponents and suppressing dissenting opinions. The uproar triggered several investigations, all of which exonerated the scientists involved. Damage has been done, however: The furor has eroded public support for action against climate change.

Predictably, media outlets have not been as quick or as loud in correcting the record as they have been in trumpeting the alleged shortcomings of the research. Yet the record of global warming is unmistakable and the link to human behavior undeniable. That is the real story and one that everyone should understand.

Last November, someone broke into the computer system of the University of East Anglia in England and gained access to thousands of e-mails and other documents at its Climate Research Unit. The hacker then leaked the materials, triggering charges that the researchers had committed various misdeeds to make the case for global warming: Allegedly, they had obstructed attempts to share information, manipulated data and tried to silence researchers whose opinions they opposed.
