The warmest years in the instrumental temperature record have occurred in the last decade (i.e. 2012-2021). The World Meteorological Organization reported in 2021 that 2016 and 2020 were the two warmest years in the period since 1850. [51] Each individual year from 2015 onwards has been warmer than any prior year going back to at least 1850. [51]
According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. 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.
500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
Previously, 2023 was named the planet’s warmest year on record. Last year’s average land and ocean surface temperatures topped the 2023 milestone by less than two-tenths of a degree Fahrenheit ...
In 2024, Earth overall saw its highest global temperature dating to the beginning of NOAA’s climate record in 1850, according to the agency. The planet’s average temperature was 1.46 degrees ...
Despite being based on data from the mid-20th century, the temperature records represent the warmest period the planet has seen in at least 100,000 years, scientists have found from many millennia ...
500 million years of climate change [7] The Phanerozoic eon, encompassing the last 542 million years and almost the entire time since the origination of complex multi-cellular life, has more generally been a period of fluctuating temperature between ice ages, such as the current age, and "climate optima", similar to what occurred in the ...
Records date back to the pre-industrial temperatures of the 19th century. Did you know 2023 was Earth’s hottest-ever year? Here’s how hot it got in Boise last year
