This is leading to long-term climate change, rising sea levels, ocean acidification and extreme weather conditions, the meteorological body found in its latest Greenhouse Gas Bulletin.
The report also noted that there has been a "resurgence of a potent greenhouse gas and ozone-depleting substance" – called trichlorofluoromethane, or CFC-11, probably linked to "increased emissions associated with the production of CFC-11 in East Asia. "
The annual Greenhouse Gas Bulletin thwarted hopes for a slowdown in carbon dioxide emissions – the byproduct of burning fossil fuels that scientists say is the main cause of the global warming that causes global warming.
"The window of opportunity for action is almost closed," he warned, adding that we are reaching concentrations of carbon dioxide not seen more than three million years ago.
Since 1990, there has been a 41% increase in the warming effect of the various greenhouse gases on the climate – known as "radioactive forcing". WMO has said that higher concentrations of carbon dioxide are melting polar caps and leading to more violent weather events, which the Bank of England said was responsible for a record loss of $ 140 billion in 2017.
WMO chief scientist Pavel Kabat said that cold weather is consistent with climate change.
The report showed how keeping the temperature below 2 ° C can reduce the risks to the well-being of the planet and its people. "Every fraction of a degree of global warming is important, as is every part of a million greenhouse gases."
The findings add to pressure on representatives of nearly 200 nations meeting in Poland next month to discuss ways to control climate change. The main objective of this meeting is to adopt an implementation plan for the Paris 2015 Agreement.
United Nations human rights chief Michelle Bachelet has sent a letter to all states saying they have legal obligations under world human rights law to prevent climate change and try to mitigate its effects. "Climate change is scientifically proven."
The number is on par with the average annual growth of greenhouse gases in the last ten years and jumped about 46% over pre-industrial levels.
Methane – atmospheric levels of which are now more than 250% above the pre-industrial level – is the second most important greenhouse gas, 60% of which comes from human activities such as cattle ranching, fossil fuels, landfills and biomass. Burning.
