The UK Meteorological Office’s annual estimate is that carbon dioxide (CO2) emissions into the atmosphere this year will be 50 percent higher than before the Industrial Revolution. The increase is driven by emissions from fossil fuel burning and deforestation, but the temporary strengthening of natural carbon sinks will be slightly smaller than usual, Xinhua news agency quoted the British National Weather Service as saying in a forecast released on Friday.
The weather patterns linked to the current La Nina event are expected to encourage the temporary growth of tropical forests, which will soak up some emissions of humanity.
Despite these La Nina-related effects, CO2 will still build up in the atmosphere and exceed 417 ppm (parts per million) for several weeks from April to June 2021, “50 percent higher than 278 ppm when widespread industrial activity began in the late 18th century”. Said the Meteorological Office.
“Although the Govt-19 epidemic means that it emits 7 percent less CO2 globally in 2020 than in previous years, it is even more likely to continue to build up in the atmosphere,” said Professor Richard Bates, who guides weather production at the office’s annual CO2 forecast.
“Accelerates man-made CO2 formation in the atmosphere. Levels have increased by 25 percent over 200 years ago, but now 30 years later we are approaching a 50 percent increase.
“Changing this trend and reducing atmospheric CO2 rises should reduce global emissions and bring global emissions to zero to stop them. If global warming is to occur within the next 30 years it should be limited to 1.5 degrees Celsius,” the professor added.
The La Nina phenomenon is part of a climate pattern called El Niோo Southern Oscillation, which describes the oscillating temperature changes between the ocean and the atmosphere in a symmetrical Pacific Ocean. La Nina is also known as the cold phase and El Nino as the hot phase.
The international community, including developing and developing countries, has already recognized the importance of joining hands in tackling climate change.
In 2021, China and the United Kingdom will hold the 15th Conference of the Parties Conference on Biological Diversity (COP15) and the 26th UN General Assembly. Also hosts the Climate Change Conference (COP26).
