Geologists reveal ancient connection between England and France

by University of Plymouth, September 14, 2018 in ScienceDaily


The British mainland was formed from the collision of not two, but three ancient continental land masses, according to new research.

Scientists have for centuries believed that England, Wales and Scotland were created by the merger of Avalonia and Laurentia more than 400 million years ago.

However, geologists based at the University of Plymouth now believe that a third land mass — Armorica — was also involved in the process.

The findings are published in Nature Communications and follow an extensive study of mineral properties at exposed rock features across Devon and Cornwall …

Heat Analysis of NOAA Data Suggests the US Is Not Seeing Increased Warming

by Leland Park, September 13, 2018 in WUWT


Given the impending global warming crisis declared by scientists, it should be easy to unambiguously demonstrate the crisis from the instrumental record. Unfortunately, when looking at the  high temperature record for the US, it does not show any warming.

Figure 1 illustrates the incremental changes in surface air temperatures based on year to year differences in station average Tmax. The data is from all active stations in the US Historical Climatology Network (USHCN) from 1895 to 2014.

The classic heat equation defines changes in heat content as being proportional to changes in temperature (ΔQ = ƒ{ΔT} ).

Thus, Figure 1 amounts to a depiction of incremental changes in heat content, without scaling in energy units. The overall net temperature change is 0, which means the net change in heat content is also zero (ΔQ = ƒ{ΔT} = ƒ{0} = 0).
