The eight warmest years on record have now occurred since 2014, the scientists, from the European Union's Copernicus Climate Change Service, reported, and 2016 remains the hottest year ever.
Earth's warmest year on record is 2016. Once again, the Arctic experienced the greatest warming relative to the average. The average temperature for that part of the world in 2022 was the highest out of any year dating back to 1900.
Summer 2021 was the hottest on record in the U.S., with the average temperature in the contiguous states reaching 74 degrees, exceeding the heat of the 1936 Dust Bowl summer by less than 0.01 of a degree (The summer of 2022 was the third-warmest in the U.S.).
The 10 warmest years in the 143-year record have all occurred since 2010, with the last nine years (2014–2022) ranking as the nine warmest years on record. For more regional details and 2022 climate statistics, see the 2022 Global Climate Report from NOAA's National Centers for Environmental Information.
2016 was hot thanks to a combination of two factors: long-term global warming, caused by human emissions; and an especially monster El Niño, which warms temperatures across much of the world.
2022 is the 8th consecutive year (2015-2022) that annual global temperatures have reached at least 1°C above pre-industrial levels, according to all datasets compiled by WMO. 2015 to 2022 are the eight warmest years on record.
On 31 January 2009 Wagga Wagga broke the all-time January record for the most days above 40.0 °C (104.0 °F) with six days recorded (the record previously being five days, which was set in 1952 and equalled in 1979 and 2001).
The highest temperature ever recorded in Australia is 50.7 °C (123.3 °F), which was recorded on 2 January 1960 at Oodnadatta, South Australia and 13 January 2022 at Onslow, Western Australia. The lowest temperature ever recorded in Australia is −23.0 °C (−9.4 °F), at Charlotte Pass, New South Wales, on 29 June 1994.
July 1743 heatwave in China - Beijing reached 44.4 °C (111.9 °F) on July 25, higher than any modern records. 11,400 people reportedly died.
“The global surface temperature anomaly is at or near record levels right now, and 2023 will almost certainly be the warmest year on record,” said Mann.
The coldest year on record occurred in 1904. Earth's average temperature has risen by over 1.8 degrees Fahrenheit (1 degree Celsius) since the onset of the industrial revolution, making yearly cold records increasingly rare. But it's not just annual cold records that are becoming rarer.
Over the last century, the average surface temperature of the Earth has increased by about 1.0o F. The eleven warmest years this century have all occurred since 1980, with 1995 the warmest on record. The higher latitudes have warmed more than the equatorial regions.
One of the warmest times was during the geologic period known as the Neoproterozoic, between 600 and 800 million years ago. Another “warm age” is a period geologists call the Paleocene-Eocene Thermal Maximum, which occurred about 56 million years ago.
Climate change made the past 7 years the warmest on record
“The continued onslaught of record years, including the seven warmest having occurred since 2015, is precisely what we expect to see due to human-caused planetary warming,” says Michael Mann at Pennsylvania State University.
Anything above is called fever, which can lead to hyperthermia in a heat wave condition. It could be fatal. It is commonly held that the maximum temperature at which humans can survive is 108.14-degree Fahrenheit or 42.3-degree Celsius. A higher temperature may denature proteins and cause irreparable damage to brain.

Australia's national mean temperature was 0.50 °C warmer than the 1961–1990 average, making 2022 the equal-22nd-warmest year on record.
The northern part of the country has a tropical climate, varying between grasslands and desert. Australia holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, and the highest sunshine duration.
In a normal year, about 175 Americans succumb to the demands of summer heat. Chicago experienced its worst weather-related disaster, with 465 heat-related deaths recorded during the period from July 11-27, 1995. Milwaukee was also severely affected, with 85 heat-related deaths recorded during the same time period.
Evidence of warming in Australia
Australia's climate has warmed since national records began in 1910. Australia's average temperature has increased on average by 1.44 ± 0.24 °C since national records began in 1910. Since 1950, every decade has been warmer than the decade before.
Kaisa Kosonen, a climate expert at Greenpeace International, said: “This report is definitely a final warning on 1.5C. If governments just stay on their current policies, the remaining carbon budget will be used up before the next IPCC report [due in 2030].”
This is expected to continue,” the UN agency said, adding that the warmest eight years have all been since 2015, with 2016, 2019 and 2020 constituting the top three. “An exceptionally strong El Niño event occurred in 2016, which contributed to record global temperatures,” WMO explained.
The warmest years globally have all occurred since 2005, with the top ten being 2016, 2020, 2019, 2015, 2017, 2018, 2014, 2010, 2013 and 2005 (tied), respectively.
