Hockey stick graphs present the global or hemispherical mean temperature record of the past 500 to 2000 years as shown by quantitative climate reconstructions based on climate proxy records. These reconstructions have consistently shown a slow long term cooling trend changing into relatively rapid warming in the 20th century, with the ...
Large-scale reconstructions covering part or all of the 1st millennium and 2nd millennium have shown that recent temperatures are exceptional: the Intergovernmental Panel on Climate Change Fourth Assessment Report of 2007 concluded that "Average Northern Hemisphere temperatures during the second half of the 20th century were very likely higher ...
In an early attempt to show that climate had changed, Hubert Lamb's 1965 paper generalised from temperature records of central England together with historical, botanical, and archeological evidence to produce a qualitative estimate of temperatures in the North Atlantic region. Subsequent quantitative reconstructions used statistical techniques ...
Global climate records are typically broken by tiny fractions of a degree, as was the case with this one: Sunday’s temperature was just 0.01 degrees Celsius above 2023’s record.
While North America’s record 134° F has stood for more than a century, Antarctica and Asia have set temperature records in the past decade.
Month after month, global temperatures are setting new records. Meanwhile, scientists and climate policymakers warn of the growing likelihood that the planet will soon exceed the warming target ...
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 .
An intense blast of cold air shattered records in the central United States this week with temperatures up to 50 degrees below average. The bitter cold is pushing into the South and East to end ...
