How long is the instrumental record of temperature?
How long is the instrumental record of temperature?
Instrumental temperature records extend back over 250 years in some locations, but only since the late 19th century has there been a sufficient number of observing stations to estimate the average temperature over the Northern Hemisphere or over the entire globe.
Did NASA change temperature records?
NASA animation portrays global surface temperature changes since 1880….Warmest decades.
| Years | Temperature anomaly, °C (°F) from 1951–1980 mean | Change from previous decade, °C (°F) |
|---|---|---|
| 2010–2019 | 0.753 °C (1.355 °F) | +0.240 °C (0.432 °F) |
| 2020–2029 (incomplete) | 0.98 °C (1.76 °F) | +0.23 °C (0.41 °F) |
Will 2020 be the hottest year on record?
NASA and Copernicus Climate Change Service estimate that 2020 is jointly the warmest year on record together with 2016. NOAA and the United Kingdom’s HadCRUT dataset both ranked 2020 as the second warmest behind 2016, with Japanese Meteorological Agency (JMA) Reanalysis ranking 2020 as the third warmest.
What is the hottest recorded temperature on Earth?
134.1 °F
The current official highest registered air temperature on Earth is 56.7 °C (134.1 °F), recorded on 10 July 1913 at Furnace Creek Ranch, in Death Valley in the United States.
Where does the instrumental temperature record come from?
The instrumental temperature record provides the temperature of Earth’s climate system from the historical network of in situ measurements of surface air temperatures and ocean surface temperatures. Data are collected at thousands of meteorological stations, buoys and ships around the globe.
Which is the longest running temperature record in the world?
Data are collected at thousands of meteorological stations, buoys and ships around the globe. The longest-running temperature record is the Central England temperature data series, which starts in 1659.
Where does the data for the sea record come from?
The temperature data for the record come from measurements from land stations and ships. On land, temperature sensors are kept in a Stevenson screen or a maximum minimum temperature system (MMTS). The sea record consists of surface ships taking sea temperature measurements from engine inlets or buckets. The land and marine records can be compared.
How does the GISS Surface Temperature Analysis work?
The GISS Surface Temperature Analysis (GISTEMP v4) is an estimate of global surface temperature change. Graphs and tables are updated around the middle of every month using current data files from NOAA GHCN v4 (meteorological stations), and ERSST v5 (ocean areas), combined as described in our publications Hansen et al. (2010) and Lenssen et al.
