Geneva: The concentration of greenhouse gases in the atmosphere reached a new record level last year, said the United Nations said Monday in the Stark warning ahead of the COP26 summit about worsening global warming.
Greenhouse gas bulletin from the United Nations Meteorological Organization said the year of the annual increase last year was above the annual average between 2011 and 2020 – and the trend continued in 2021.
WMO said the economic slowdown was caused by a pandemic Covid-19 triggered by the internal decline in New emissions, but do not have an impact that can be seen at the atmospheric greenhouse gas level and its growth rate.
The organization said that during emissions continued, global temperatures would continue to increase.
And given the long life of carbon dioxide (CO2), the level of temperature that has been observed will last for decades even if emissions are reduced quickly to zero clean.
COP26, the UN Climate Change Conference, is being held at Glasgow from October 31 to November 12.
“Greenhouse gas bulletin contains striking scientific messages for climate change negotiators at COP26,” said Head of WMO Petrter Talas.
“At the level of increasing the current greenhouse gas concentration, we will see an increase in temperatures at the end of this century far exceeding the target of the Paris 1.5 to two degrees Celsius above the pre-industrial level.” We are far from the lane.
“The main Greenhouses gas is CO2, methane and nitro oxide.
CO2 is the most important, accounting for around 66 percent of the heating effect on the climate.
CO2 concentration reaches 413.2 parts per million by 2020, up 2.5 ppm, and on 149 percent of the 1750 pre-industrial levels, said WMO.
The report said that about half of the CO2 emitted by human activities remained in the atmosphere, with the other half ending in the ocean and mainland.
“The last time the CO2 concentration was comparable 3-5 million years ago, when the temperature of 2-3C is warmer and sea level is 10-20 meters higher than now.
But there were no 7.8 billion people later, “said Talas.
The average methane reached a new high of 1,889 parts per billion by 2020, up 11ppp in the previous year, and was in 262 percent of pre-industrial benchmarks.
About 40 percent.
Methane is emitted from natural resources such as wetlands, while 60 percent comes from human activities, including rice agriculture and landfills.
The average nitro oxide reaches 333.2 ppb, up 1.2 ppb, at 123 percent level .
WMO said that with increasing greenhouse gas emissions, along with increasing temperature, the planet can expect more extreme weather.
It includes hot and rainfall is superb, melting ice, rising sea levels and ocean acidification – all of which will achieve impact A distant socio-economy.
“We need to change our commitment to an action that will have an impact on gas that encourages climate change,” Talas said.
” We need to review the industry, energy and transportation system and all our way of life.
The necessary changes are economically affordable and technically possible.
There is no time to lose.
“Euan Nisbet, from the University of London’s greenhouse gas group, compared the measurement of greenhouse gas to” slipping into a car accident “.” The disaster gets closer but you can’t stop it.
You can clearly see the accident ahead, and what you can do is howl.
“Dave Reast, Director of Edinburgh Climate Change Institute, said the report gave a” brutal “assessment of the assessment of police achievement so far:” Epic failed “.
