Human activity has increased the direct warming effect of carbon dioxide (CO₂) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index . In 2015, the global average CO₂ concentration reached 399 parts per million, increasing by a record amount of almost 3 ppm. From the end of the Ice Age to the beginning of the industrial era, atmospheric carbon dioxide remained remarkably stable at 278 ppm.

The latest analysis of observations from the WMO Global Atmosphere Watch (GAW) Programme.
Publish Date: 16 May 2017
Recognizing that expanded and improved observations now make possible a broader assessment of global atmospheric chemistry, the WMO Global Atmosphere Watch programme has published a new report on global and regional trends in reactive gases. This group of gases includes such chemicals as surface ozone, nitrogen oxides, carbon monoxide, sulfur dioxide, and volatile organic compounds, many of which are considered to be harmful pollutants. The first issue of the Reactive Gases Bulletin reviews long-term observation data on volatile organic compounds (VOCs) and discusses past and recent trends....
World Meteorological Day was established in 1960 to make the work of National Meteorological and Hydrological Services better known and appreciated by the public of all countries.
Every year, the 23rd of March, the World Meteorological Organization (WMO) and the international meteorological community join efforts to celebrate the World Meteorological Day, commemorating the coming into force in 1950 of the WMO Convention through which WMO assumed the previous responsibilities of the International Meteorological Organization (IMO), established in 1873 to foster international collaboration in meteorology for the protection of life and property.
Every year on 23 March, the World Meteorological Organization (WMO) and the international meteorological community join in celebrating World Meteorological Day, to commemorate the coming into force of the WMO Convention on 23 March 1950, precisely 30 days after the day when the thirtieth instrument of ratification of the Convention was deposited by countries wishing to join the new Organization.
Every year, the World Meteorological Organization (WMO) and the international meteorological community celebrate World Meteorological Day, commemorating the coming into force of the WMO Convention on 23 March 1950, precisely 30 days after the date of deposit of the 30th instrument of ratification or accession by Members.
Records of ancient civilizations contain innumerable references to weather and climate and rudimentary but ingenious instruments were devised by different cultures to observe the basic meteorological parameters, often in conjunction with astronomy and astrology.
