Pre-Industrial climate change in South America: the Middle Age was Warm, Glaciers Shrank

By Dr. Sebastian Lüning & Prof. Fritz Vahrenholt – Re-Blogged From http://notrickszone.com
(German text translated/edited by P Gosselin)

Global warming alarmist scientists like claiming that the well documented Medieval Warm Period (MWP) was merely a regional phenomenon, and not global. However a new publication by Lüning et al adds yet another study that shows the warm period from 1000 years ago was indeed global.

The climate of the Middle Ages is still a mystery. In many parts of the world a warming period occurred, which can still not be satisfactorily simulated by the current climate models.

Scientific Apophenia

By Kip Hansen – Re-Blogged From WUWT

apophenia_definitionScience, as a whole, advances or fails to advance in large part in a direct relationship to the presence or absence of bias in its research efforts.  There are many types of bias, and these have been discussed in the pages of various Climate Science blogs and publications over the years. [ see the short list at the end of the essay ].

One of the most common biases that skew research and slow or even stop the progress of science is Confirmation Bias:

2018 U.S. tornadoes on Track to be Lowest Ever

By Anthony Watts – Re-Blogged From WUWT

While claims of increased severe weather due to “climate change” aka “global warming” are thrown about by the media, with recent claims that more and more tornadoes are shifting east in the U.S., the fact of the matter is that the trend for strong tornadoes is decidedly down, according to data from NOAA. The US is on track to have the lowest annual tornado count in 65 years.

Climate Research in the IPCC Wonderland

By Dr. Tim Ball – Re-Blogged From WUWT

A fascinating 2006 paper by Essex, McKitrick, and Andresen asked, “Does a Global Temperature Exist.” Their introduction sets the scene,

It arises from projecting a sampling of the fluctuating temperature field of the Earth onto a single number (e.g. [3], [4]) at discrete monthly or annual intervals. Proponents claim that this statistic represents a measurement of the annual global temperature to an accuracy of ±0.05 ◦C (see [5]). Moreover, they presume that small changes in it, up or down, have direct and unequivocal physical meaning.

The word “sampling” is important because, statistically, a sample has to be representative of a population. There is no way that a sampling

Inconvenient Data: No Trend in Florida Hurricane Strikes

By Roy W. Spencer, Ph. D. – Re-Blogged From WUWT

Florida Major Hurricane Strikes: Still No Trend

I’ve updated a plot of Florida major hurricane strikes since 1900 with Hurricane Michael, and the result is that there is still no trend in either intensity or frequency of strikes over the last 118 years:

BOMBSHELL: Audit of Global Warming Data Finds it Riddled With Errors

By Anthony Watts – Re-Blogged From WUWT

Just ahead of a new report from the IPCC, dubbed SR#15 about to be released today, we have this bombshell- a detailed audit shows the surface temperature data is unfit for purpose. The first ever audit of the world’s most important temperature data set (HadCRUT4) has found it to be so riddled with errors and “freakishly improbable data”  that it is effectively useless.

Rooting Out Scientific Corruption

By Paul Driessen – Re-Blogged From WUWT

Recent actions show reform is in the wind, but much remains to be done, especially on climate

Dr. Brian Wansink recently resigned from his position as Columbia University professor, eating behavior researcher and director of the Cornell “food lab.” A faculty investigation found that he had misreported research data, failed to preserve data and results properly, and employed dubious statistical techniques.
