The global temperature record shows the fluctuations of the temperature of the atmosphere and the oceans through various spans of time. There are numerous estimates of temperatures since the end of the Pleistocene glaciation, particularly during the current Holocene epoch.
22 lis 2023 · About 250 million years ago, around the equator of the supercontinent Pangea, it was even too hot for peat swamps! Preliminary results from a Smithsonian Institution project led by Scott Wing and Brian Huber, showing Earth's average surface temperature over the past 500 million years.
10 wrz 2020 · For the first time, climate scientists have compiled a continuous, high-fidelity record of variations in Earth’s climate extending 66 million years into the past. The record reveals four distinctive climate states, which the researchers dubbed Hothouse, Warmhouse, Coolhouse, and Icehouse.
The average global annual temperature hovered around 13.7 °C (56.7 °F) from the 1880s through the 1910s. During the 1920s to 1940s, temperatures climbed about 0.1 °C (0.18 °F) each decade. Mean global temperatures then stabilized at roughly 14.0°C (57.2 °F) until the 1980s.
Overall, Earth was about 2.45 degrees Fahrenheit (or about 1.36 degrees Celsius) warmer in 2023 than in the late 19th-century (1850-1900) preindustrial average. The 10 most recent years are the warmest on record.
Global temperatures reconstructed by taking a spatially-weighted average of 59 proxy sea surface temperature records from around the global oceans. All records span the last 150,000 years, but the dataset degrades to approximately 10 records by 800,000 years ago.
According to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880.
