English: Graph of temperature anomaly from 20,000 years ago through 10,000 years ago, a time period encompassing recovery from the most recent ice age. Data is from EPICA Dome C Ice Core.
Older Peron warm and wet, global sea levels were 2.5 to 4 meters (8 to 13 feet) higher than the twentieth-century average 3900: 5.9 kiloyear event dry and cold. 3500: End of the African humid period, Neolithic Subpluvial in North Africa, expands Sahara Desert 3000 – 0: Neopluvial in North America 3,200–2,900: Piora Oscillation, cold
Reconstruction of the past 5 million years of climate history, based on oxygen isotope fractionation in deep sea sediment cores (serving as a proxy for the total global mass of glacial ice sheets), fitted to a model of orbital forcing (Lisiecki and Raymo 2005) [2] and to the temperature scale derived from Vostok ice cores following Petit et al. (1999).
Deglaciation is the transition from full glacial conditions during ice ages, to warm interglacials, characterized by global warming and sea level rise due to change in continental ice volume. [1] Thus, it refers to the retreat of a glacier , an ice sheet or frozen surface layer, and the resulting exposure of the Earth 's surface.
Highest heat index: In the observation above at Dhahran, Saudi Arabia, the heat index ("feels like" temperature) was 81.1 °C (178.0 °F). [ 202 ] Highest temperature with 100% relative humidity : A temperature of 34 °C (93 °F) with 100% relative humidity in Jask , Iran , on 21 July 2012.
Earth last year shattered global annual heat records, flirted with the world’s agreed-upon warming threshold and showed more signs of a feverish planet, the European climate agency said Tuesday.
A study in 2020 estimated that the average global temperature during the warmest 200 year period of the HCO, around 6,500 years ago, was around 0.7 °C warmer than the mean for nineteenth century AD, immediately before the Industrial Revolution, and 0.3 °C cooler than the average for 2011-2019. [6]
France launched a heat watch warning system after an extended heat wave in 2003 was estimated to have caused 15,000 deaths — many of them older people in city apartments and homes without air ...
