In 2021, greenhouse gases in the Earth’s atmosphere reached record levels.

In less than two weeks, world leaders will assemble in Egypt for the 27th “conference of parties” to the United Nations Framework Convention on Climate Change, also known as COP27.

The summit this year, which starts on Nov. 6, will feature discussions between nations about how to reach their emission-reduction goals, what adaptation activities to prioritize, and how to offer funds to nations who are least to blame for global warming and are most affected by climate change.

The WMO report gives the negotiations more urgency. It was discovered that carbon dioxide levels in the atmosphere reached 415.7 parts per million last year, which translates to more than 415 carbon dioxide molecules for every million other gas molecules present in the atmosphere.

Because of global coronavirus lockdowns in 2020, the earth temporarily experienced a drop in carbon emissions, but the WMO reported that there are signs that the climb in carbon dioxide levels this year will continue.

Methane, a strong greenhouse gas, had concentrations of 1,908 parts per billion last year, and nitrous oxide levels reached 334.5 parts per billion, according to the report.

Around 60% of the world’s methane emissions are attributed to human activity, including agriculture, coal mining, and oil and gas extraction, according to studies. The increase in methane concentrations last year appears to be the consequence of “both biological and human-induced processes,” according to the WMO, even though the cause is unclear.

After carbon dioxide and methane, nitrous oxide is the third-largest greenhouse gas that contributes to climate change. Approximately 43% of the emissions of nitrous oxide are caused by human activity, including farming, industry, burning fossil fuels, and other activities.

According to the WMO, greenhouse gas concentrations increased somewhat more last year than they did from 2019 to 2020, growing faster than the average yearly growth rate over the previous ten years.

The agency’s report makes use of information from the Global Atmosphere Watch network, which gauges air composition and greenhouse gases.
The report’s conclusions, according to Taalas, show that “time is running out.”

He declared in the statement, “We are headed in the wrong direction. The concentrations of the principal heat-trapping gases are still rising, particularly the record acceleration in methane levels.
