RC: CBCCB, 全对;
测量偏差measurement bias:systematic errors.
e.g. a metallic ruler provides erroneous measurements under temperature variations.
eliminating: unattainable.
the critical: identification and subsequent adjustment.
e.g. David--> 0.5 F decline in 1945 in oceanic, but not terrestrial temperature records.
cause on distinct methodologies between British and the US.:
1, British relied on bucket-collected --> 50% of the data originating from British vessels from 1945
the US. ustilize engine coolant which higher --> 80% of readings from American ship data predominate during wartime(before 1945);
meaning: leading climate scientists to integrate this into their models. |
