<p>And a previous se-Earth Science question that was answered citing the same NOAA information, may be found <a href="https://earthscience.stackexchange.com/questions/23139/1-5-above-what/23146#23146">here</a>. Based on existing information regarding the estimated warming in the industrial period, the average temperature for pre-industrial period provided in that answer was determined by simple math to be about 13.68°C. This corroborates the answer by Ash, above.</p>

<p>I keep seeing that the rise in global temperature was measured against pre-industrial times. However, I can't find a global average for this period (circa 1700 to 1850). Because the Little Ice Age or the Holocene climatic optimum will probably not be a reference. What were the conditions?</p>
