This leads to long-term climate change, sea level rise, ocean oxidation and more extreme climatic conditions, the meteorological body found in the latest greenhouse gas bill.
The report also notes that there has been a "revival of a powerful greenhouse gas and ozone-depleting substance" – called trichlorofluoromethane or CFC-11 – possibly linked to "increased emissions associated with the production of CFC-11 in East Asia".
The annual greenhouse gas bill has rejected hopes of slowing down carbon dioxide emissions, a by-product of fossil fuel burning, which according to scientists is the main cause of the global warming-causing effect.
"The window of opportunity for action is almost closed," he warned, adding that we have reached carbon dioxide concentrations that have not been observed for more than three million years.
Since 1990, there has been an increase of 41 percent in the warming effect of various greenhouse gases on the climate, known as "radioactive compulsion". The World Organization for Migration says higher carbon dioxide concentrations have melted ice caps and led to more violent meteorological events that, according to the Bank of England in 2017, caused a record $ 140 billion in insurance losses.
WMO Chief Scientist Paul Kabat said the unusually cold weather is in line with climate change.
The report showed that keeping the temperature below 2 ° C could reduce the risks to the well-being of the planet and its people. "Every part of global warming matters as well as every part of one million greenhouse gases."
The findings add to the pressure on envoys from nearly 200 countries that gather next month in Poland to discuss ways to overcome climate change. The main purpose of this meeting is to adopt a plan to implement the 2015 Paris Agreement.
UN chief for human rights, Michel Bachelet, has sent a letter to all countries, telling them that they have a legitimate commitment to the world human rights law to prevent climate change and to try to mitigate its effects. "Climate change is scientifically proven".
This figure is equal to the average annual growth rate of greenhouse gases over the past ten years and has jumped by about 46% of pre-industrial levels.
Methane – the atmospheric levels, which now exceed 250% above the pre-industrial level – is the second most important long-term greenhouse gas, 60% of which comes from human activities such as livestock rearing, fossil fuel use, landfill and biomass burning.
