The four basic ones its indicators climate change broke news record in 2021, the UN announced today, warning that the global energy system is leading humanity to destruction.
The gathering greenhouse gases, rising ocean levels, ocean temperature and acidification reached new record levels last year, according to the report on “State of the global climate in 2021Compiled by the World Meteorological Organization (WMO).
This report is “a bleak procession of humanity’s failure to tackle climate deregulation. Fossil fuels are an environmental and economic impasse“, Stressed the UN Secretary General Antonio Guterres.
«“The global energy system is broken and it 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 planGuterres estimated.
The WMO noted that human activity causes changes on Earththe oceans and the atmosphere, with harmful 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 the head of the WMO Peteri Taalas.
«The heat trapped by man-made greenhouse gases will warm the planet for many generations to come. Rising sea levels, warming and acidification of the oceans will continue for many hundreds of years unless ways are found to remove carbon from the atmosphere.“, He added.
Overheat
The four key indicators of climate change «compose an image of a world that is overheating“, The report notes.
The greenhouse gas concentration is broken new record level in 2020with 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 increase 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 suggested five actions to boost the transition to renewable energy sources: end fossil fuel subsidies, triple investment in renewable energy, abolish bureaucracy, ensure the supply of raw materials for renewable energy technologies and make these technologies universally available, public goods, available.
