Two days ago Kenneth presented an impressive flurry of scientific, peer-reviewed charts published over the past 15 months (46 alone in 2018). Much to the surprise of alarmist scientists, global warming is weak at best.
Lack of warming a global phenomenon
According to Kenneth, these new papers show that “nothing climatically unusual is happening”. For example a publication by Polovodova Asteman et al shows that continental Europe’s temperatures are lower today than they were on other occasions over the past 2000 years:

Today’s warming doesn’t stand out
The authors write that the contemporary warming of the 20th century “does not stand out in the 2500-year perspective” and is “of the same magnitude as the Roman Warm Period and the Medieval Climate Anomaly.”
A number of strident global warming scientists prefer to dismiss the significance of Europe’s temperature record, claiming that it is local in nature and does not tell us what is really happening globally. However, other papers fully contradict this. For example, a paper by Wündsch et al., 2018 shows us that the warming today in South Africa also is nothing unusual.
It’s global, stupid
Temperature reconstructions show the same is true in Southeast Australia, according to McGowan et al., 2018, Northern Alaska (Hanna et al., 2018), the Tibetan Plateau (Li et al., 2018), South Korea (Song et al., 2018), Antarctica (Mikis, 2018), to cite just a few among dozens of others.
“Warming holes” surprise scientists
Meanwhile new findings by Partridge et al., 2018 show in fact that other regions have cooled. The eastern US “annual maximum and minimum temperatures decreased by 0.46°C and 0.83°C respectively.”
The surprising winter cooling has led scientists to dub the eastern US a “warming hole”, where scientists blame oceanic cycles for the unexpected cooling.
Greenland within normal, cooler than 1930s
Greenland often gets cited by alarmists as a climate canary in a coal mine due to its massive ice sheets and their potential to cause dramatic sea level rise should they melt. But a brand new study by Mikkelsen et al., 2018 shows that surface temperatures going back over 150 years are lower than they were in the 1930s!

Looking at the above Greenland surface temperature chart, we see that the mercury plummeted some 5°C from 1930s to the 1980s before thankfully rebounding in the 1990s and 2000s. Here as well there exist no signs for warming alarm.
Greenland cooling again since 2000
Furthermore, much to the surprise of global warming scientists, Greenland temperatures have again been falling since 2000. Westergaard-Nielsen et al., 2018 examined the most recent and detailed trends based on MODIS (2001–2015) and concluded that if there is any general trend for Greenland it is “mostly cooling”.
South Pole cooling, getting icier
At the other end of the planet at the South Pole, new findings by Cerrone and Fusco, 2018 confirm the large increase in the southern hemisphere sea ice and suggest it “arises from the impact of climate modes and their long-term trends”.
They write that the results indicate a progressive cooling has affected the year-to-year climate of the sub-Antarctic since the 1990s and that the SIC [sea ice concentration] shows upward annual, spring, and summer trends.
