(a) Annual mean instrumental temperature records, identified in Table 6.1.

The Mann et al reconstruction has the same amplitude increase as the full Northern Hemisphere annual mean instrumental record over the calibration interval (1900 - 1980).

Not exact matches

The annual global mean temperature for every year since the TAR has been among the 10 warmest years since the beginning of the instrumental record.

Although the regions largely coincide with the continents rather than climatological criteria, the annual mean temperature averaged over these regions explains 90 % of the global mean annual temperature variability in the instrumental record»

We thus aggregated environmental data, estimating annual means for our instrumental data that spanned April to September.

txt From Ray Bradley «The graph patches together 3 things: Mann et al NH mean annual temps + 2 sigma standard error for AD1000 - 1980, + instrumental data for 1981 - 1998 + IPCC («do not quote, do not cite» projections for GLOBAL temperature for the next 100 years, relative to 1998.»

Shown for comparison is the instrumental NH annual mean record 1856 - 1980 (red).

The space - time structure of natural climate variability needed to determine the optimal fingerprint pattern and the resultant signal - to - noise ratio of the detection variable is estimated from several multi-century control simulations with different CGCMs and from instrumental data over the last 136 y. Applying the combined greenhouse gas - plus - aerosol fingerprint in the same way as the greenhouse gas only fingerprint in a previous work, the recent 30 - y trends (1966 — 1995) of annual mean near surface temperature are again found to represent a significant climate change at the 97.5 % confidence level.
