Document Summary
Temperature, processes that are influenced by temperature, other climate variables include precipitation and extreme events. Issues with measuring temperature: not one site is representative of another, rural vs. urban changes, maritime vs. continental, exposure of instrument to sun, skin temperature, time of measurement. Solutions: do(cid:374)"t a(cid:374)alyze the actual te(cid:373)perature, report the difference between observed temp and the mean temp over a long-term reference period, temperature anomaly. All records have gaps in time and over space. We must fill these in to examine global temperature; this is done by interpolating to a grid. Climate series are noisy due to interannual and decadal variability. Scatter about the mean can lead people to imagine things especially in short time series. Global mean surface temperatures have risen by 0. 85c when estimated by a linear trend over the last. It has risen by 0. 89c over the period of 1901-2012 and by about 0. 72c over the period of.
