The largest eruptions of the last 100 years, such as the Mount Pinatubo eruption in 1991 and Mount Agung eruption in 1963-1964, have been followed by years with global mean temperatures 0.1 °C to 0.2 °C below long-term trends at the time. [citation needed] Land use change like deforestation can increase greenhouse gases through burning biomass.
The geologic temperature record are changes in Earth's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.
Many weather records are measured under specific conditions—such as surface temperature and wind speed—to keep consistency among measurements around the Earth. Each of these records is understood to be the record value officially observed, as these records may have been exceeded before modern weather instrumentation was invented, or in ...
The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890. The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4]
NASA scientists estimated that in 2024, Earth was about 2.65 degrees Fahrenheit (1.47 degrees Celsius) hotter than the average from the mid-19th century — a period from 1850 to 1900.
Within the stations, all of them have at least 10 years of data, 2/5 have more than 50 years of data, and 1/10 have 100 years of data. [3] Version 1, or more commonly notated as V1 was the collection of monthly mean temperatures from 6,000 stations. There were, as of 2022, 3 subsequent versions of the GHCN – M have been created as described ...
