World Meteorological Organization WMO research it is revealed that the corona pandemic has had only a minor impact on the fight against climate change.
– Reductions in CO2 emissions have had little effect on the reduction of atmospheric concentrations due to past and current emissions. There are just as many effects on the longevity of carbon dioxide levels, WMO writes in its research bulletin.
Carbon concentrations are expected to fall by 4-7% this year due to government corona measures.
However, it will not help in the fight against climate change.
– Emissions should be reduced to zero.
The biggest restrictive measures in the first Corona wave were taken in early April. At that time, daily carbon dioxide concentrations decreased by 17 percent compared to the 2019 level.
Nevertheless, emissions were in line with 2006 levels, as growth in CO2 emissions has only accelerated over the last 15 years.
There is already a rush in the fight against climate change. The years 2016–2020 are expected to be about 1.1 degrees Celsius warmer than the average temperatures of 1850–1900.
In addition, temperatures are expected to be 0.24 warmer than average temperatures in 2011-2015.
In the Paris Climate Agreement in 2015, states committed to keeping average temperature rises well below two degrees compared to pre-industrial times. At the same time, efforts are being made to limit warming to less than 1.5 degrees.
The World Meteorological Organization points out that technology already makes it possible to reduce emissions to zero if countries agree on measures to slow down climate change.
The WMO also recalls that in the mid-2010s, 27 percent of the world’s population, or 1.9 billion people, lived in areas where water is scarce. By 2050, the number will grow to 2.7-3.2 billion people.
– Many of these extreme weather events have clearly identified the human impact, WMO recalls in its research release.
