A paper recently published attempts to measure the relationship between ice accumulation and temperature in Antarctica for the last 31000 years.
The study is based in West Antarctica. I won’t go into the details, which were covered by WUWT here. But what was interesting were the temperature graphs included, based on ice cores.
We can see that for most of the time since the end of the ice age temperatures have been much higher than now. We can also clearly see the sharp drop coinciding with the LIA, and that temperatures were similar to now in the MWP.
We are continually told that humans are pushing the earth’s climate into unknown territory, but once again we see this is not true. As far as the Antarctic is concerned, all the evidence points to the 20thC rise in temperatures being no more than a natural recovery…

Important study: Waste heat is a major source of national warming, significantly pollutes climatic recordPosted: June 19, 2016
From the department of the “Hottest Year Evah” (as touted by NOAA, NASA and alarmist media, based on temperatures measured by ground based, UHI polluted, thermometers).
Important study. Read on…
I covered a similar study back in 2008 which you can read about here. This study takes it to a national level, suggesting once again that surface temperature records are not really measuring a “climate change” signal in entirety. The author of the study says that “correlation of temperature above background levels and national energy consumption is very high”. Seems like a no-brainer to me. This has far reaching consequences for the validity of the surface temperature record and its ability to discern a real CO2 induced climatic signal. – Anthony
Larry O’Hanlon writes on the AGU blog:
The greenhouse effect isn’t the only thing warming things up. There is also the waste heat released when we generate and use energy – even clean energy. Yet the regional impact of that heat – which moves from warm buildings, engines and power plants into the world around us –…
