New Study, Scientists: ’20th Century Warming Not Very Obvious In Our Reconstruction’
A new 368-year tree ring temperature reconstruction has established that regional (China) summer temperatures were warmer than they are now (2012) during the mid-1600s and early 1700s, and that the temperature variations can be linked to variations in solar activity, volcanic forcing (cooling), and natural oceanic-atmospheric oscillations (AMO/PDO).

The authors are intent on pointing out that it is “noteworthy that 20th century warming was not very obvious in our reconstruction.” This “noteworthy” finding is mentioned four different times in the paper.

The lack of a conspicuous 20th century warming — and the warmer periods during the 1600s and 1700s — are clearly shown in the summer temperature graph below:...

Global Warming Expedition Stopped In Its Tracks By Arctic Sea Ice
A group of adventurers, sailors, pilots and climate scientists that recently started a journey around the North Pole in an effort to show the lack of ice, has been blocked from further travels by ice. The Polar Ocean Challenge is taking a two month journey that will see them go from Bristol, Alaska, to Norway, then to Russia through the North East passage, back to Alaska through the North West passage, to Greenland and then ultimately back to Bristol. Their objective, as laid out by their website, was to demonstrate “that the Arctic sea ice coverage shrinks back so far now in the summer months that sea that was permanently locked up now can allow passage through.”

There has been one small hiccup thus-far though: they are currently stuck in Murmansk, Russia because there is too much ice blocking the North East passage the team said didn’t exist in summer months, according to Real Climate Science.

Real Climate Science also provides a graph showing that current Arctic temperatures — despite alarmist claims of the Arctic being hotter than ever — is actually below normal....
