The four key indicators of climate change broke new records in 2021, the UN announced today, warning that the global energy system is leading humanity to disaster.
Greenhouse gas concentrations, rising ocean levels, temperature and ocean acidification reached new record levels last year, according to the World Meteorological Organization’s 2021 Global State of the Climate Report. WMO).
The report is “a bleak procession of human failure to tackle climate deregulation. Fossil fuels are an environmental and economic impasse,” said UN Secretary-General Antonio Guterres.
“The global energy system is damaged and is bringing us closer and closer to climate catastrophe,” he warned, calling for “an end to fossil fuel pollution and an accelerated transition to renewable energy before our only home burns down.”
“The only sustainable future is renewable. The good news is that the lifeline is in front of us. Wind and solar energy are already available and in most cases cheaper than coal and other fossil fuels. If we all act together, “The transition to renewable energy can be traced back to the 21st century peace plan,” Guterres said.
The WMO noted that human activity causes changes in the Earth, oceans and atmosphere, with detrimental and long-term effects on ecosystems.
The report confirmed that the past seven years were the hottest ever recorded.
2021 is one of the hottest years ever recorded, with global temperatures averaging 1.1 degrees Celsius above pre-industrial times.
“Our climate is changing before our eyes,” said WMO chief Peteri Taalas.
“The heat trapped by man-made greenhouse gases will warm the planet for many generations to come. Sea level rise, heat and acidification of the oceans will continue for many hundreds of years if no way is found to eliminate them.” “carbon from the atmosphere,” he added.
Overheat
The four key indicators of climate change “compose a picture of a world that is overheating,” the report notes.
Greenhouse gas concentrations broke a new record in 2020, with carbon dioxide reaching 413.2 microparticles per million (ppm) worldwide, an increase of 149% over the pre-industrial era.
The data show that carbon dioxide levels continued to rise in 2021 and early 2022.
Moreover, the average sea level increased to reach a new record in 2021, as it increased by an average of 4.5 millimeters per year from 2013 to 2021.
Ocean temperatures also rose, reaching a record high last year and surpassing the 2020 record.
The report also states that the hole in the Antarctic ozone layer is “extremely deep and extensive”, reaching 24.8 million square kilometers in 2021.
Guterres proposed five actions to boost the transition to renewable energy sources: “end subsidies for fossil fuels, triple investment in renewable energy sources, abolish bureaucracy, ensure the supply of raw materials renewable energy sources and to characterize these technologies as global, public goods, freely available.
