The warmest day on record for the entire planet was 22 July 2024 when the highest global average temperature was recorded at 17.16 °C (62.89 °F). [20] The previous record was 17.09 °C (62.76 °F) set the day before on 21 July 2024. [ 20 ]
Series of reliable temperature measurements in some regions began in the 1850—1880 time frame (this is called the instrumental temperature record). The longest-running temperature record is the Central England temperature data series, which starts in 1659. The longest-running quasi-global records start in 1850. [3]
The temperature reached 47.6 °C (117.7 °F) in Lytton on June 28 and 46.6 °C (115.9 °F) on June 27, both records. These record high temperatures are a result of the 2021 Western North America heat wave. [76] [184] June 30 – The Lytton wildfire kills 2 people [112] and burned 206,926 acres. [185]
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 .
Global average temperatures show that the Medieval Warm Period was not a planet-wide phenomenon, and that the Little Ice Age was not a distinct planet-wide time period but rather the end of a long temperature decline that preceded recent global warming. [1] The temperature record of the last 2,000 years is reconstructed using data from climate ...
The IPCC Fifth Assessment Report (AR5 WG1) of 2013 examined temperature variations during the last two millennia, and cited the following reconstructions in support of its conclusion that for average annual Northern Hemisphere temperatures, "the period 1983–2012 was very likely the warmest 30-year period of the last 800 years (high confidence ...
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
The State of the Climate summarizes the global and regional climate of the preceding calendar year and places it into a historical context. In addition, notable climatic anomalies and events are discussed. Major findings in the 2010 report were: 2010 was one of the two warmest years of the instrumental temperature record
