It's been a tough couple of weeks for the big warmers out there.

Big data finds the Medieval Warm Period – no denial here
Jennifer Marohasy

We began by deconstructing the six-proxy series from different geographic regions – series already published in the mainstream climate science literature.  One of these, the Northern Hemisphere composite series begins in 50 AD, ends in the year 2000, and is derived from studies of pollen, lake sediments, stalagmites and boreholes.
Typical of most such temperature series, it zigzags up and down while showing two rising trends: the first peaks about 1200 AD and corresponds with a period known as the Medieval Warm Period (MWP), while the second peaks in 1980 and then shows decline. In between, is the Little Ice Age (LIA), which according to the Northern Hemisphere composite bottomed-out in 1650 AD.  (Of course, the MWP corresponded with a period of generally good harvests in England – when men dressed in tunics and built grand cathedrals with tall spires.  It preceded the LIA when there was famine and the Great Plague of London.)
Ignoring for the moment the MWP and LIA, you might want to simply dismiss this temperature series on the basis it peaks in 1980: it doesn’t continue to rise to the very end of the record: to the year 2000?
In fact, this decline is typical of most such proxy reconstructions – derived from pollen, stalagmites, boreholes, coral cores and especially tree rings.  Within mainstream climate science the decline after 1980 is referred to as “the divergence problem”, and then hidden.
In denial of this problem, leading climate scientists have been known to even graft temperature measurements from thermometers onto the proxy record after 1980 to literally ‘hide the decline’.  Phil Jones, the head of the Climate Research Unit, University of East Anglia, aptly described the technique as a ‘trick’.
Grafting thermometer data onto the end of the proxy record generally ‘fixes’ the problem after 1980, while remodelling effectively flattens the Medieval Warm Period.
There are, however, multiple lines of evidence indicating it was about a degree warmer across Europe during the MWP – corresponding with the 1200 AD rise in our Northern Hemisphere composite.  In fact, there are oodles of published technical papers based on proxy records that provide a relatively warm temperature profile for this period. This was before the Little Ice Age when it was too cold to inhabit Greenland.

Scientists find 91 new volcanoes under Antarctic ice sheet
The volcanoes were not previously identified because their tops do not break through the surface of the Antarctic ice sheet.
Monday 14 August 2017

The largest volcanic region on Earth has been found thousands of meters below the surface of the ice sheet covering Antarctica.
A survey of the region of the West Antarctic Rift System has revealed 91 new volcanoes hidden within the ice.
The new volcanoes are on top of the 47 whose peaks are above the ice and were already known about.
The volcanoes range in height from 100m to a towering 3,850m tall.
Geologists say the range has similarities to east Africa's volcanic ridge, which was previously thought to have the densest concentration of volcanoes in the world.

Always learning new stuff, and it will continue, making conclusions with limited knowledge is always fraught with risk. Sorry Al, again.

NW actually discovered some facts, thinks he has an aha moment on climate change. Proves again he can't comprehend the basics of science.

My science is actually science. You and NW just know about trolling.
