in glacier recession, earlier springs, reduced snow cover etc.» Another «inconvenient truth» for denialists to avoid mentioning or acknowledging while overblowing the UHI issue.
The second error is obvious from the fact that the recent warming is seen in the oceans, the atmosphere, in Arctic sea ice retreat,
in glacier recession, earlier springs, reduced snow cover etc., so even if all met stations were contaminated (which they aren't), global warming would still be «unequivocal».

A (2) Modern warming,
glacier and sea ice

Most (about 2/3) of the recent
recession of the
glacier occurred between 1860 and 1957 and can not be ascribed to the anthropic emissions of CO2 which were then insignificant: 0,083 Gt - C

Nevertheless, the fast
glacier recession in the tropics seems at first sight to be consistent with an increase
in tropical freezing heights of 100 m over the period 1970 to 1986 as reported by Diaz and Graham (1996), corresponding to an increase of 0.5 °C at tropical high mountain levels, which they also link to increases
in tropical SST since the mid-1970s (Figure 2.10).
