There are small differences in the way various agencies
handle global temperature data, yielding sometimes different rankings for particular months and years.
Since
annual global temperature data is moderately noisy due to natural fluctuations, trend significance can only be detected with high confidence after considering the physical basis.
- The difficulty of obtaining
meaningful global temperature data, due to land use changes, equipment changes, location changes, gaps in records, varying station numbers and gaps in geographic coverage.
However, I recall reading recently — but was unable to find the reference, unfortunately — that it generally takes about 17 years
of global temperature data to reach that 95 % level.
Although not as exceptional as the values for February 2016 and February 2017, it was in line with the upward trend of 0.18 °C per decade seen in
global temperature data from 1979 onwards.
Although not as exceptional as the values for March 2016 and March 2017, it was in line with the upward trend of 0.18 °C per decade seen
in global temperature data from 1979 onwards.
An analysis of
global temperature data by scientists with the U.S. National Aeronautics and Space Administration (NASA) found that 2017 was the second - hottest year on record since 1880 — which...
New
global temperature data released on Friday by NASA put March at 2.3 °F (1.28 °C) above the 1951 - 1980 average for the month, making it the warmest March on record.
New global temperature data published today by the EU's Copernicus programme show that the 12 month period to the end of October was the warmest on record.
Scientists return fire at CEI and Pat Michaels for bogus charges on global temperature data record
Climate Central scientists and statisticians made these calculations based on an average of
global temperature data reported by NASA and the National Oceanic and Atmospheric Administration (NOAA).
Last month was far and away the hottest February on record for the planet, by a margin that has surprised even the climate scientists who closely
monitor global temperature data.
The graphic displays
monthly global temperature data from the U.K. Met Office and charts how each month compares to the average for the same period from 1850 - 1900, the same baselines used in the most recent report from the Intergovernmental Panel on Climate Change.
