Warm periods in the 20th century are not unprecedented during the last 2,000 years

by Prof. Quansheng Ge, August 8, 2017 in ClimateChangeDispatch

Prof. Quansheng Ge and his group from the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, collected a large number of proxies and reconstructed a 2000-year temperature series in China with a 10-year resolution, enabling them to quantitatively reveal the characteristics of temperature change in China over a common era.

Global Warming Caused Vikings to Become Terrorists

by David Middleton, August 7, 2017 in WUWT 

So… If climate change caused the Vikings to turn their plowshares into swords, abandoning their farms to become terrorists… the climate change would have been of the warming variety.  I’m not a farmer, but it seems to me that global warming would have actually enhanced the Vikings’ ability to farm up around the Arctic Circle.

nother BOM scandal: Australian climate data is being destroyed as routine practice

by JoNova, August 7, 2017 in ClimateChangeDispatch

In the mid-1990s thermometers changed right across Australia — new electronic sensors were installed nearly everywhere. Known as automatic weather sensors (AWS) these are quite different to the old “liquid in glass” type.

The electronic ones can pick up very short bursts of heat—so they can measure extremes of temperatures that the old mercury or liquid thermometers would not pick up unless the spike of heat lasted for a few minutes.

It is difficult (impossible) to believe that across the whole temperature range that these two different instruments would always behave in the exact same way.

Recorded temperatures at the Bureau­ of Meteorology’s Thredbo Top automatic weather station have dropped below -10C in the past week, after action was taken to make the facility “fit for ­purpose”.

A record of the Thredbo Top station for 3am on Wednesday shows a temperature reading of -10.6C. This compares with the BoM’s monthly highlights for June and July, both showing a low of -9.6C.

The BoM said it had taken immed­iate action to replace the Thredbo station after concerns were raised that very low temperatures were not making it onto the official record.

Harmonic Analysis of Worldwide Temperature Proxies for 2000 Years

by H.J. Lüdecke and C.A. Weiss, August 2017

We provide a new confirmation for the link between solar activity and climate cycles by wavelet analysis showing a remarkably good agreement of the power of the ~190 – year period for temperatures and solar activity over 9000 years (see Fig.4. lower panel). As (Fig.2 and Table 2 ) show, the periods of ~1000 and ~460 years are also apparently common in records of temperatures and cosmogenic nuclides.

C’était vraiment une personnalité exceptionnelle, tant sur le plan humain que scientifique. Sa disparition inopinée laisse un vide profond, et un grand désarroi parmi ceux qui l’ont connu

CO2 emission, CO2 absorption

by Alan Siddons, July 26, 2017

The chart below is taken directly from figures provided by the U.S. government’s Carbon Dioxide Information Analysis Center (CDIAC) website, specifically its 2016 Global Carbon Project spreadsheet on the Historical Budget tab. In terms of gigatons of carbon, and from 1770 to 2004, it itemizes the growth rate of radiative forcing by atmospheric CO2 and the growth rate of oceanic absorption, what is known as a “carbon sink.”

New York Times Shifts Towards Extreme Climate Fraud

by Tony Heller, July 29, 2017 in DeplorableClimateScinceBlog

The New York Times said yesterday that heatwaves in the past were “virtually unheard of in the 1950s”, temperatures approaching 130 degrees didn’t used to occur, and summer temperatures have shifted towards more extreme heat.

(…) Every single claim in the article is patently false, and the exact opposite of reality. The authors intentionally started their study in a cold period, after the extreme heat of the 1930’s.

The IPCC gives us good news about climate change, but we don’t listen

by Larry Kummer, July 29, 2017, in WUWT

Now that the alarmists have had their day trumpeting the IPCC’s worst case scenario (it’s unlikely and becoming more so), let’s look at their best case scenario (hidden by journalists). The risk probabilities are asymmetric: the good news is more likely than the bad news. This is inspirational, telling people that we can make a better world.
