It was found that the world concentrations of three types of greenhouse gases, such as carbon dioxide, which cause global warming, were all the highest in the history of observation last year.
Despite the decrease in fossil fuel-derived emissions due to the spread of the new coronavirus infection, the overall situation where the increase in greenhouse gases cannot be stopped has become clear again.
WMO = World Meteorological Organization analyzed last year's data observed by meteorological authorities and research institutes in each country on the global average concentrations of the three major greenhouse gases and reported the results.
According to this,
▽ carbon dioxide was 413.2ppm,
▽ methane was 1889ppb, and
▽ nitrous oxide was 333.2ppb,
all of which exceeded the average, the highest since 1984 when observations were started all over the world.
In addition, the increase from the previous year to last year
was 2.5 ppm for carbon dioxide,
11 ppb for methane
, and 1.2
ppb for
nitrous oxide,
all of which are higher than the average increase over the past 10 years.
In addition, according to the report, last year, emissions from fossil fuels decreased by about 5.6% due to restrictions on movement and factory shutdown due to the spread of the new coronavirus infection, but as a whole, greenhouse gas emissions The situation where the increase cannot be stopped has been highlighted again.
The Japan Meteorological Agency, which was involved in the analysis, said, "If global warming continues, the frequency of droughts due to sunshine and disasters due to heavy rains will increase, and the situation is serious. To reduce the ever-increasing greenhouse gases, a longer-term perspective It is necessary to take measures at. "
