Also, New York's enormous population, human activity, and vast amounts of large buildings and streets, which absorb sunlight during the day, contribute significantly to the urban heat island effect. Meteorological records have been kept at Central Park since 1821, although the station was relocated to a different part of the park on January 1 ...
Other techniques which have been used include examining records of the time of crop harvests, the treeline in various locations, and other historical records to make inferences about the temperature. These proxy reconstructions are indirect inferences of temperature and thus tend to have greater uncertainty than instrumental data.
The annual average temperature across the state ranges from around 39 °F (4 °C) over the Adirondack Mountains to near 53 °F (12 °C) across the Hudson Valley and Long Island, to around 56 °F (13 °C) within New York City. [2] Weather in New York is heavily influenced by two air masses: a warm, humid one from the southwest and a cold, dry ...
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).
Christopher C. Burt, a weather historian writing for Weather Underground, believes that the 1913 Death Valley reading is "a myth", and is at least 2.2 or 2.8 °C (4 or 5 °F) too high. [13] Burt proposes that the highest reliably recorded temperature on Earth could still be at Death Valley, but is instead 54.0 °C (129.2 °F) recorded on 30 ...
The New York Stock Exchange (NYSE) and American Stock Exchange (AMEX) closed as a result of the storm. It was the first time in history that the NYSE closed for a full day due to the weather, and the first time since 1918 that AMEX had done so. All commodity exchanges in New York City and the National Association of Securities Dealers also ...
Old Weather is a Zooniverse project and is a collaboration between researchers at many institutions, including the University of Oxford, Oxford Martin School, ACRE (International Atmospheric Circulation Reconstructions over the Earth), Naval-History.Net of Penarth, Jisc which encourages UK colleges and universities in the innovative use of digital technologies, the National Maritime Museum at ...
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 ...
