NEW DELHI: The abundance of heat-trapping greenhouse gases in the atmosphere once again hit a new record last year as the economic slowdown from Covid-19 remained unaffected, shows green house gas (ghg) bulletin NS world meteorological organization (wmo), released on Monday.
It noted that although there was a temporary drop in new emissions, it hardly affected atmospheric levels of GHGs and their growth rates compared to their annual growth rates above the 2011–2020 average.
The bulletin comes on a day the UN’s climate change body updated its synthesis report of countries’ climate actions – called Nationally Determined Contributions (NDCs) – confirming its September findings that more than 190 All available NDCs in countries will increase by about 16% globally. GHG emissions in 2030 compared to 2010.
A comparison of the latest findings by the Intergovernmental Panel on Climate Change (IPCC) suggests that such an increase, unless reversed quickly, could result in a temperature increase of about 2.7 °C by the end of the century,” the report said. UNFCCC.
The WMO’s GHG Bulletin shows that emissions trends have continued in 2021, indicating that from 1990 to 2020, the radiative forcing (warming effects on our climate) by long-term GHGs increased by 47%, including CO2. was about 80%. This increase.
Numbers based on monitoring by WMO Global Atmosphere Watch The network shows the concentration of carbon dioxide (CO2) – the most important GHG – reached 413.2 parts per million (ppm) in 2020 and is 149% of pre-industrial levels. Similarly, methane (CH4) is 262% and nitrous oxide (N2O) is 123% of the level in 1750 when human activities started disrupting the Earth’s natural balance.
“COP26 in the GHG Bulletin has a clear, scientific message for climate change negotiators. At the current rate of increase in greenhouse gas concentrations, we will expect temperatures of 1.5 to 2 °C above Paris Agreement pre-industrial levels by the end of this century.” will see an increase in,” said WMO Secretary General Petri Talas.
He said, “The amount of CO2 in the atmosphere passed the 400 ppm milestone in 2015. And just five years later, it exceeded 413 ppm. It’s much more than just a chemical formula and a figure on a graph.” This has huge negative implications for our daily lives and well-being, the state of our planet, and the future of our children and grandchildren.”
They noted that the last time Earth experienced comparable concentrations of CO was 3–5 million years ago, when temperatures were 2–3 °C warmer and sea levels were 10–20 m higher than now. “But then there weren’t 7.8 billion people,” Talas said, underlining how dangerous the current concentration of GHGs can be to humanity.
