Changing temperature anomaly baselines

I wanted to check whether the choice of baseline can affect the calculation of  global temperature anomalies from station data. Each temperature index (GISS, Berkeley, CRU) uses different normalisation periods for calculating weather station temperature anomalies. I was surprised to … Continue reading

January 2019 global average temperature remains unchanged – 0.73 C

Global averaged surface temperature for January 2019 was 0.73C using my spherical triangulation method merging GHCNV3 with HadSST3. This is unchanged since December 2018. The baseline used is always 1961-1990. The Northern Hemisphere is shown here. and here is the … Continue reading

How does temperature depend on CO2?

Robert Rohde has produced a very nice animation of global temperatures as a function of CO2 levels in the atmosphere. Of course it is designed for public relations purposes in order to show increasing CO2 causes warming.  He even uses … Continue reading
