The “hockey stick” graph has been both a linchpin and target in the climate change debate. As a plot of average Northern Hemisphere temperature from two millennia ago to the present ...

The graph is correct. It shows the average temperature in each year since 1880, using data from NASA. The problem with it is that it is misleading, using a scale that intentionally hides the ...

The black line for temperatures below 0 degree Fahrenheit (deg F) (-17.8 deg Celsius) - the lowest temperature data point - is an extrapolation of the data. As we can see, the efficiency can be ...

The possible temperature range is limited by 25°C = &100°C but extrapolation to 125°C seems to be acceptable ... different capacitors operating at different voltages, one can plot graphs similar to ...
