False.
Wrong.
Untrue.
Incorrect.
(and stating it many times does not change that.)
According to Mann’s hockey stick chart the (somewhat imaginary) hypothetical temperature increase should have been 0.5 deg C in the first few years following 1998. (see below)
However what Mann predicted has not (repeat not) come to pass
It did not happen.
It never occurred.
It has not come to pass.
It was not (repeat not) born out.
To wit:
“Since 2000, temperatures have been warmer than average, but they did not increase significantly. Data courtesy of NOAA’s National Climatic Data Center.”
Since this article was last updated, the slowdown in the rate of average global surface warming that took place from 1998–2012 (relative to the preceding 30 years) has unequivocally ended. Scientists have learned more about the physical factors that contributed to the short-term trend, and they have documented the continued build up in sub-surface ocean heat during the period. Check out our latest Q&A on this topic: Did global warming stop in 1998?
Editor’s note: Updated June 4, 2015
New analysis through 2014 shows that temperature is once again rising at about the same pace as it did over the second half of the 20th century. PRESS RELEASE.
Using the data that were available at the time (through 2012), the last climate report from the Intergovernmental Panel on Climate Change concluded that there had been no statistically significant increase in global surface temperature from 1998-2012.
According to a new NOAA analysis, the warming trend during that period was somewhat smaller than the longer-term (1951-2012) trend, but it wasn’t zero. And with the latest data calibrations and the most recent two years of global temperatures added to the series—including record-warm 2014—the warming experienced since 1998 is on par with the rate observed in the second half of the 20th century.
Basically, the new analysis confirms what climate scientists have said all along: natural variability (such as the patterns described in this article) may cause the rate of warming to change from one decade to the next, but global warming is still underway.
On one side we have hundreds of scientist, researchers etc. who say in effect “Global warming is basically true, but what Michael Mann said is false, false false. More importantly he failed, failed failed, to properly differentiate between observed data and scary made-up hypotheticals that science now knows were 100% untrue.”
If you want people to trust science you have to be willing to (occasionally) call-out the whack job political activists who masquerade as scientists. Michael Mann appears to be one of those. Certainly hos hockey stick was wrong. Certainly science now proves that.
Basically the new analysis confirms that Michael Mann “prediction” was not false, wrong., inaccurate. It never came to pass.
Earth Day 1970 ring a bell?
Why not just embrace science?
We don’t have to reject all of AGW theory to say that from time to time an alarmist politcal type produces junk science and that appears to be what happened in Michael Mann’s case
