During 2017, there were 150 graphs from 122 scientific papers published in peer-reviewed journals indicating modern temperatures are not unprecedented, unusual, or hockey-stick-shaped — nor do they fall outside the range of natural variability. We are a little over halfway through 2018 and already 108 graphs from 89 scientific papers undermine claims that modern era warming is climatically unusual.
For the sake of brevity, just 13 (15%) of the 89 new papers are displayed below.
The rest of the non-hockey-stick scientific papers and graphs published thus far in 2018 can be viewed by clicking the link below.

During 2017, there were 150 graphs from 122 scientific papers published in peer-reviewed journals indicating modern temperatures are not unprecedented, unusual, or hockey-stick-shaped — nor do they fall outside the range of natural variability. We are a little over 4 months into the new publication year and already 81 graphs from 62 scientific papers undermine claims that modern era warming is climatically unusual.

Roughly 20 years ago, climate scientist Michael Mann published his famous “hockey stick” graph that he says “galvanized climate action” by showing unprecedented global warming.
Mann used the 20-year anniversary of the graph to opine on the “industry-funded” attacks “to discredit the iconic symbol of the human impact on our climate,” which Mann claimed had withstood criticism.
“Yet, in the 20 years since the original hockey stick publication, independent studies, again and again, have overwhelmingly reaffirmed our findings, including the key conclusion: recent warming is unprecedented over at least the past millennium,” Mann wrote in Scientific American on April 20.
However, the two Canadian researchers who found serious flaws in the “hockey stick” study’s data and methodology disputed Mann’s characterization of the graph’s legacy.

Twenty years ago today: The infamous “hockey stick” graph that crystalized global warming and ignited the climate wars was published, and became known as MBH98. The science in it was so bad, it is credited with spawning the modern climate skeptic movement.
Original “hockey stick” temperature graph in Nature, 1998. The Y axis shows the Northern hemisphere mean temperature, in degrees Celsius; the zero line corresponds to the 1902 – 1980 mean.

From Keele University and the “It’s like deja vu all over again” department with the leader of the “ship of fools” thrown in for comic relief. Long-time WUWT readers surely remember the single “Most influential tree in the world” from the Yamal fiasco, where the “signal” in one tree (YAD06) biased an entire paper with a hockey stick shape, making it worthless. Well, here we are again with another single tree used to define the entire globe. Obviously they’ve learned nothing, then again, it’s Chris Turney.

It was four months ago that an article entitled 80 Graphs From 58 New (2017) Papers Invalidate Claims Of Unprecedented Global-Scale Modern Warmingappeared on this website. The article received international attention and was “shared” tens of thousands of times.
In the last 4 months, 40 more graphs taken from 30 more new peer-reviewed scientific papers have made their way into the ever-growing volume of evidence that today’s climate is not only not unprecedented or unusual in the context of the last millennium, but modern temperature values are still among the coldest of the last 10,000 years.

Well, Dr. James Hansen, the man who invented the global warming scam and our favorite failed serial doomcaster, recently addressed the cratering of a 30-year prediction he made in 1988.
Back then, he said the globe would warm up by one full degree by 2018 under the “business as usual” rubric … not. Here’s the story as written up in “Spin” magazine in 1988.

In understanding climate change risk, and deciding on the ‘if’ and ‘what’ of ‘action’, we need to acknowledge that we don’t know how the climate of the 21st century will play out (Deep Uncertainty, folks). Four possibilities:
-
It is possible that human-caused climate change will be swamped by much larger natural climate variability.
-
It is possible/plausible that the sensitivity of the climate is on the low end of the IPCC envelope (1.0-1.5C), with a slow creep of warming superimposed on much larger natural variability.
-
It is possible/plausible that the IPCC projections are actually correct (right for the wrong reasons; too much wrong with the climate models for much credibility, IMO).
-
It is possible that AGW and natural variability could conspire to cause catastrophic outcomes

Penn State climate scientist, Michael ‘hockey stick’ Mann commits contempt of court in the ‘climate science trial of the century.’ Prominent alarmist shockingly defies judge and refuses to surrender data for open court examination

A great synthesis very useful and impressive, well argued. From 1998 until today.

Professor Michael Mann, inventor of the climate Hockey Stick, has just shamelessly shifted the dreaded climate tipping point to 2020.
Until recently Mann claimed 2016/17 was a climate tipping point.
