Average annual temperature ranges in Santiago are from 3 to 14 degrees Celsius (37 to 57 degrees Fahrenheit) in July to 12 to 29 degrees Celsius (54 to 84 degrees Fahrenheit) in January.
-- For the locations in the contiguous U.S. examined in this study, the past six years (POR 2011 - 2016) have
seen average annual temperatures that are 1.2 °F above the current 30 - year climatological average used by NOAA (1981 - 2010).
Granted, while the
globally averaged annual temperatures for the years since the record warm year of 1998 have not exceeded the 1998 record, the global temperatures since 1998 have remained high, ranking as the second, third and fourth warmest years of the last 125 years (and quit possibly the last 2,000 + years).
But findings from deep drilling in the Songliao Basin show that the climate swings on land were far more drastic, with
average annual temperatures going up or down by as much as 20 °C over tens of thousands of years — a geological eyeblink.
The study
predicts average annual temperatures in New York state will rise by 4 to 9 degrees by 2080 and precipitation will rise by 5 to 15 percent, with most of it in the winter....
This is particularly noteworthy in the case of Kansas City,
whose average annual temperature dropped by 1.2 °F after its official NWS site was moved in 1972 from downtown to the airport 20 miles northwest.
If 2013 does come in below the 20th century average, it would be the first year since 1996 to have done so, and would end a 16 - year long run of
above average annual temperature for the U.S..
Figure 2.5: Projected change in
average annual temperature over the period 2071 - 2099 (compared to the period 1970 - 1999) under a low scenario that assumes rapid reductions in emissions and concentrations of heat - trapping gases (RCP 2.6), and a higher scenario that assumes continued increases in emissions (RCP 8.5).
The central and eastern parts of the country have warmed the most.3
Average annual temperatures in New South Wales — where Sydney is the capital city — rose by 1.94 ° F (1.08 ° C) from 1950 to 2007.3
But it is
the average annual temperature rather than the monthly temperature that really counts.
Unlike previous Pliocene models, this «no ice» version returned temperatures 18 to 27 F warmer than today's
average annual temperatures for the Canadian Arctic and Greenland, coming closer to what the historical data pulled from the ground said.
The average annual temperature would have been about freezing — possibly rising as high as 70 degrees Fahrenheit in summer and plummeting to less than — 10 °F in the winter.
He says that Helliker and Richter's analysis relies on
the average annual temperature; it doesn't take into account the fact that trees grow only during the warm season, and then only at warm times of day.
Helliker and Richter found that they could explain the ratios if they assumed that, even in the northernmost regions where
the average annual temperature dips to -10 °C, the leaves maintain an average temperature of 21.4 °C.
