摘要
The graph shows global monthly near-surface air temperature anomaly estimates since 1850 from eight sources spanning three different estimation approaches. The plotted values are temperature anomalies — the difference between a month’s temperature from a given series and the mean for that month of the year for that series across a reference interval, here taken as 1951 – 1980. The overlaid trend is a 4th order polynomial fit to the mean of the plotted series.
Data sources
1. NASA GISTEMP global temperature series[1]
2. HadCRUT4 global temperature series[2]
3. HadCRUT + Cowtan & Way global temperature series (version 2)[3]
4. NOAA National Climate Data Center global temperature series[4]
5. Berkeley Earth land + ocean global temperature series[5]
6. NCEP / NCAR reanalysis (version 1) global average surface air temperatures[6][7]
Satellite MSU remote sensing cannot measure meteorological surface air temperature (typically defined as that at 2 m height). The best that can be obtained is a temperature estimate across the lower troposphere,[8] about the bottom 5000 m of atmosphere[8] That temperature is of course much colder than the surface temperature and varies somewhat differently with climatic influences. Nevertheless it is often compared with surface temperatures.[9] The satellite series do not extend across the reference interval adopted for the graph. Instead they are each rebased so that their mean across the 30 year interval 1979 – 2008 equals the mean of the five instrumental series across the same interval.
7. RSS temperature lower troposphere global temperature series (RSS TLT version 3.3)[10]
8. UAH temperature lower troposphere global temperature series (UAH TLT version 5.6)[11]
Future predictions
For comparison, the Intergovernmental Panel on Climate Change Fifth Assessment Report[12] central temperature estimates for 2050 for representative concentration pathways RCP6 (mid range) and RCP8.5 (high) are also shown.
