Lying? You mean changing their understanding of something new as more information becomes available? That's how science works they use the best info available, and change their understanding as more info becomes available.
Even today, in their newest letter, they are still trying to obfuscate the real situation and are certainly not apologizing for their prior stance.
At any rate, this claim that scientists are never dishonest or wrong, they just "update their beliefs" as more information becomes available, is getting very tedious. That's not what they're doing. "Science" is constantly bombarding our political leaders with wildly extreme statements delivered not just with 100% confidence, but the assertion that you aren't even allowed to disagree because it's a "scientific consensus". People read the papers and point out that they're making false assumptions or are otherwise pseudo-scientific, but they're suppressed and ignoring. Then when that "consensus" turns out to have been completely wrong a bunch of apologists appear to explain that scientists can never be wrong by definition.
Well, guess what? If a certain type of person constantly make confident statements as a group and insists reasoned disagreement is illegitimate, then is repeatedly proven to be wrong, all their statements become seen as less reliable. As a group.
