Perhaps you thought that the whole “planet isn’t warming” meme was killed by this summer’s bombshell Koch-funded study. After all, it found ”global warming is real,” “on the high end” and “essentially all” due to carbon pollution.
Sadly, denial springs eternal. Long-debunked denier David Rose has an article in the Daily Mail, “Global warming stopped 16 years ago, reveals Met Office report quietly released … and here is the chart to prove it.”
The piece is so misleading, even the UK Met Office felt a need to instantly debunk it with a blog post that included this chart.

Since Rose managed to find one misleading chart to push his myth, I thought I would dig up ten serious ones that show the reverse, including the top chart from Skeptical Science, the great Australian blog, which is derived from the data in the Koch-funded study.
Note: “Skeptics” is an Aussie word for denier or disinformer. The British have their own words — Rose or Mail:
- David Rose destroys his credibility and the Daily Mail’s with error-riddled climate science reporting
- Daily Mail Slammed for Ignoring Scientific Truth We’re Still Warming and Human Emissions Will Dwarf Any Solar Changes
So one has to assume going in that any climate piece in the Mail with Rose’s name on it is somewhere between misinformation and disinformation. The latest piece tends toward the latter. Heck, even Judith Curry complains she was misquoted, as Media Matters notes.
The Met Office, part of the UK Defence Ministry, explained, it’s absurd to look at a cherry-picked “trend from August 1997 (in the middle of an exceptionally strong El Nino) to August 2012 (coming at the tail end of a double-dip La Nina)”:
As we’ve stressed before, choosing a starting or end point on short-term scales can be very misleading. Climate change can only be detected from multi-decadal timescales due to the inherent variability in the climate system. If you use a longer period from HadCRUT4 the trend looks very different. For example, 1979 to 2011 shows 0.16°C/decade (or 0.15°C/decade in the NCDC dataset, 0.16°C/decade in GISS). Looking at successive decades over this period, each decade was warmer than the previous – so the 1990s were warmer than the 1980s, and the 2000s were warmer than both. Eight of the top ten warmest years have occurred in the last decade.
Over the last 140 years global surface temperatures have risen by about 0.8ºC. However, within this record there have been several periods lasting a decade or more during which temperatures have risen very slowly or cooled. The current period of reduced warming is not unprecedented and 15 year long periods are not unusual.
The warming trend is clear in a chart from an earlier Met Office post “Noughties confirmed as the warmest decade on record“:
Here’s an analogy to the notion it hasn’t warmed from the El-Nino-fueled summer of 1997 through the La-Nina-cooled summer of 2012. Imagine your kid got 11 B’s and 1 A+ in 9th grade science class. Then, in 10th grade science, she gets 9 A’s and 2 A+’s — but her last grade was “just” an A. Would you say she is doing better in science class or worse in science class?
If you prefer your charts from U.S. agencies using the good ‘ole Fahrenheit scale, here’s NOAA’s version of the previous chart, which notes “Every year of 2000s [was] warmer than 1990s average”:
