Strong UHI Temperature Biases Confirmed in USA

WUWT readers may recall that NOAA did an experiment at Oak Ridge National Laboratory that vindicated my findings about the effects of local urbanization on surface temperature measurements.

The urban heat island (UHI) effect is strongly affected by urban-scale changes to local land surfaces. Basically, the more asphalt, concrete, buildings, etc. that exist near a thermometer, the more the overnight low temperature is biased upwards due to heat storage.

Sea Level RiseMeasured from Space?

There have been so many very good essays on Global Sea Level Rise by persons all of whom have a great deal more expertise than I.   Jo Nova hosts a dozen or so excellent essays, which point at another score of papers and publications, for the most part clearly demonstrating that there are two contrarian positions on sea level rise in the scientific community:  1) Sea level has risen, is rising and will continue to rise at a rate approximately 8-12 inches (20-30 centimeters) per century — due to geological and long-term climatic forces well beyond our control;  and 2a) Other than explicit cases of Local Relative SLR, the sea does not appear to be rising much over the last 50-70 years, if at all.  2b) If it is rising due to general warming of the climate it will not add much to position 1.
