How are climate normals calculated?
A “normal” is the 30-year average of a particular variable’s measurements, calculated for a uniform time period. Climate normals are derived from weather and climate observations captured by weather stations.

What are the seven climate variables?
WMO uses a list of 7 state-of-the-climate indicators that are based on the 54 Global Climate Observing System (GCOS) Essential Climate Variables, including surface temperature, ocean heat content, atmospheric carbon dioxide (CO2 ), ocean acidification, sea level, glacier mass balance and Arctic and Antarctic sea ice …
Is it hotter than normal 2021?
Earth’s average land and ocean surface temperature in 2021 was 1.51 degrees F (0.84 of a degree C) above the 20th-century average. It also marked the 45th consecutive year (since 1977) with global temperatures rising above the 20th-century average. The years 2013-2021 all rank among the ten-warmest years on record.
What do climatologists mean by normal?
Climatological normal or climate normal (CN) is a 30-year average of a weather variable for a given time of year. Most commonly, a CN refers to a particular month of year, but it may also refer to a broader scale, such as a specific meteorological season.
Who runs the WMO?
Headquartered in Geneva, Switzerland, the WMO is governed by the World Meteorological Congress, composed of member states, which meets every four years to set policies and priorities. The Congress is led by an Executive Council led by the President, currently Gerhard Adrian of Germany.
