In a report released today, the World Meteorological Organization recorded a record high for greenhouse gas concentrations last year, faster than the annual average for the past decade, despite a temporary decline during the pandemic blockade. Said that it increased in.
The news came when the United Nations Climate Change Agency warned that the world was out of scope to reach its goal of reducing emissions as part of its international efforts to curb global warming. came.
Both announcements were made a few days before the United Nations Climate Change Conference began in Glasgow, Scotland. Many environmental activists, policy makers and scientists say October 31st-November. Twelve events, abbreviated as COP26, represent important and decisive opportunities for concrete efforts to address the goals set by the 2015 Paris Agreement.
“The Greenhouse Gas Bulletin contains a clear and scientific message to climate change negotiators at COP26,” said World Meteorological Organization Secretary-General Petteri Taaras on atmospheric heat trap gas. He mentioned the annual report of his institution. “By the end of this century, the current rate of increase in greenhouse gas concentrations will be well above the Paris Agreement’s target of 1.5-2 degrees Celsius (2.7-3.6 degrees Fahrenheit).”
According to the report, concentrations of carbon dioxide, methane, and nitrous oxide were all above levels in the pre-Industrial Revolution era before 1750, when human activity “began to upset the Earth’s natural balance.” rice field.
This report leverages information gathered by networks that monitor the amount of greenhouse gases remaining in the atmosphere after some amounts have been absorbed into the ocean and biosphere.
The Geneva-based agency also points out in its report signs of concern for new developments. Deforestation has reduced some of the Amazon rainforests from carbon “sinks” that draw carbon dioxide from the atmosphere into CO2 sources. Humidity in the area, it said.
“One of the impressive messages from our report is that the Amazon region, which was once a carbon sink, is now a source of carbon dioxide,” says Taalas. “And that’s because of deforestation. This is especially due to climate change in regions of the world. Humidity and rainfall are low.”
Oksana Tarasova, head of the WMO’s Atmosphere and Environmental Research Division, said the first results showing Amazon’s transition from sink to source, but they are specific to Amazon, not the entire rainforest. He said it was from the southeast.
The United Nations Climate Change Agency today said that the assessment of formal commitments by the countries that signed the Paris Agreement suggests that the world can reduce its emissions by 83-88% by 2050 compared to 2019. Said to.
Even more worrisome, based on previous formal commitments, emissions in 2030 are projected to be 16% higher than in 2010.
“Such a rise could lead to a temperature rise of about 2.7C (4.9F) by the end of the century, unless it changes rapidly,” the United Nations said.
Experts say emissions will be halved by 2030 compared to 2010 levels to meet Paris’ goal of keeping global warming below 2 ° C, ideally 1.5 ° C. He argued that it needed to reach essentially zero by the middle of the century.
Patricia Espinosa, Head of the United Nations Climate Change Agency, said:
“We’re far from science saying we should be,” she added.
However, recent announcements by China and India, the world’s number one and third largest emitters, are not included in the analysis as they have not yet officially submitted their targets to the United Nations.
Alok Sharma, who presides over UN talks in Glasgow, said progress has been made since the agreement with Paris was reached in 2015, when existing emission reduction forecasts showed warming of up to 4 degrees Celsius. rice field.
According to the WMO report, the global average concentration of carbon dioxide, a major greenhouse gas, reached a new high of 413.2 ppm last year. According to the WMO, the increase in 2020 was higher than the annual average for the last decade, despite a 5.6% reduction in carbon dioxide emissions from fossil fuels due to COVID-19 restrictions.
Levels above 400 ppm, which violated in 2015, “have a major negative impact on our daily lives and well-being, the state of the planet, and the future of our children and grandchildren,” Taalas said.
Anthropogenic carbon dioxide emissions from the burning of fossil fuels such as oil and gas and the production of cement represent about two-thirds of the impact of global warming on climate. Overall, the pandemic recession last year “had no recognizable impact on greenhouse gas atmospheric levels and their growth rates, but new emissions temporarily declined,” the WMO said.
