Sailing with buckets
Abrupt drop in temperatures in 1940s, how accurate?
LET"s hear it from sailors of the 1940s. One group collected sea water in buckets and measured the temperature of sea water; the other group measured the temperature of water used for cooling engines. Often, the temperature from buckets was lower since the water cooled a little due to evaporation. The second method yielded a higher temperature, given the heat of engines.
Biased methods, say scientists.
Global sea-surface temperatures have shown a general increase since the early 1900s, but the period between 1945 and 1960 shows an abrupt drop in temperatures. Climate change sceptics have used this data to argue that rising temperatures had more to do with increased solar activity than greenhouse gases. According to statistics, in the six-month period following August 1945, the global temperature decreased by about 0.3
