This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
Christopher C. Burt, a weather historian writing for Weather Underground, believes that the 1913 Death Valley reading is "a myth", and is at least 2.2 or 2.8 °C (4 or 5 °F) too high. [13] Burt proposes that the highest reliably recorded temperature on Earth could still be at Death Valley, but is instead 54.0 °C (129.2 °F) recorded on 30 ...
The minimum temperature increased by 0.4-2.8 °C, the maximum temperature by 0.3-1.8 °C. 13 stations show a decreasing total annual precipitation by 5-20%. Six stations experienced an increase by 5-10%. The number of rainy days decreased by 3-10% in most of the stations; In most stations, relative humidity decreased while evaporation increased
Since a 1 °C temperature change and a 1 K change in absolute temperature are the same, these cancel and no conversion is required. Example: For a typical New York City winter day with high of 40 °F and low of 30 °F, the average temperature is likely to be around 35 °F. For such a day we can approximate the HDD as (65 − 35) = 30.
For an exact conversion between degrees Fahrenheit and Celsius, and kelvins of a specific temperature point, the following formulas can be applied. Here, f is the value in degrees Fahrenheit, c the value in degrees Celsius, and k the value in kelvins: f °F to c °C: c = f − 32 / 1.8 c °C to f °F: f = c × 1.8 + 32
Anders Celsius's original thermometer used a reversed scale, with 100 as the freezing point and 0 as the boiling point of water.. In 1742, Swedish astronomer Anders Celsius (1701–1744) created a temperature scale that was the reverse of the scale now known as "Celsius": 0 represented the boiling point of water, while 100 represented the freezing point of water.

The Climate Prediction Center said there is a 35% chance this El Niño will become “historically strong," which means a temperature of 2 degrees Celsius (3.6 Fahrenheit) above average.
The next world record low temperature was a reading of −88.3 °C (−126.9 °F; 184.8 K), measured at the Soviet Vostok Station in 1968, on the Antarctic Plateau. Vostok again broke its own record with a reading of −89.2 °C (−128.6 °F; 184.0 K) on 21 July 1983. [8] This remains the record for a directly recorded temperature.
