The world meteorological organization confirmedthat the 2019 year came in second place among the hottest years. The global average temperature last year was 1.1 degrees above the average temperature in the pre-industrial (1850-1900 year) and lost only in 2016, when the temperature rose by 1.2 degrees above pre-industrial, and reached a record for the entire history of observations.
Regular measurements that we can use today to assess global temperatures, meteorologists have been held since 1850. The average temperature for the period 1850 to 1900 is used as the base for the assessment of climate change. Data sets, that uses the WMO to estimate the average temperature, include information from weather stations and satellites.
The averaged data for the five datasets provided by the American meteorological Agency NOAA, NASA, and several other meteorological organizations showed that the temperature in 2019 was 1.1 degrees above pre-industrial levels, although 2016 kept the first place — through a combination of long-term warming trend and a very powerful manifestation of El niño in that year.
In the message of the WMO notes that the average temperature for five years (2015 to 2019) and a decade (2010 to 2019) remains at a record high. The average temperature in each decade since the 1980-ies, becomes higher. Climatologists believe this trend will continue because the concentration of greenhouse gases is growing. According to scientists, the end of the century while maintaining the same rate of growth in greenhouse gas concentrations, to the end of the century, the excess over pre-industrial levels will reach 3-5 degrees. In addition to growth temperature, last year, continued melting of glaciers, rising sea levels, recorded weather extremes.
To assess the rate of warming, scientists use a measurement of heat energy stored in the ocean, which absorbs about 90 percent of the excess heat. A new study published in the journal Advances in Atmospheric Sciences, shows that the excess heat energy in the oceans amounted to about 228 of zettajoule, 25 of zettajoule higher than in 2018.
In early 2019, the meteorologists once again recorded a record concentration of carbon dioxide in the atmosphere, and then proved by all standards of physics, that global warming is due to anthropogenic influence. If you want to understand global warming, view our manual.
