Although no trend does not improve.
The levels of greenhouse gases trapped by heat in the atmosphere hit a new record, according to a report released Thursday by the United Nations meteorological agency, which reveals that it is unlikely There is no sign of reversal of this trend, responsible for level rise, ocean acidification and extreme weather conditions.
Kabat spoke at a press conference to present the latest WMO bulletin on greenhouse gases, which indicated that atmospheric levels had reached a record level the previous year . Also increased concentrations of methane and nitrous oxide; This has further increased the level of greenhouse gases and substances that deplete the ozone layer. A report released earlier this year by the Intergovernmental Panel on Climate Change stated that net emissions must reach zero by 2050 so that temperatures remain high at 1.5 degrees Celsius, is the goal of many developing countries.
"The scientific evidence is unequivocal".
Professor Corinne Le Quere, director of the Tyndall Center for Climate Change Research at the University of East Anglia, said she was "not surprised, but I am very "concerned that the main greenhouse gases are constantly increasing. "The window of opportunity is almost closed," said WMO Secretary-General Petteri Taalas in a statement.
"The last time the Earth had experienced a comparable concentration of carbon dioxide, three to five million years ago, the temperature was 2 to 3 ° C warmer and the sea level 10 to 20 meters higher than today, "said Taalas.
The annual Greenhouse Gas Bulletin has canceled hopes for a slowdown in carbon dioxide emissions – the by-product of the burning of fossil fuels, which scientists say is the main cause of the greenhouse gas effect. greenhouse that causes global warming.
Without reducing greenhouse gases, Taalas said "climate change will have more and more destructive and irreversible effects on life on Earth".
This report, which looked at what the planet could look like if the global temperature reached 1.5 ° C compared to 2 ° C above pre-industrial levels ", shows that deep and rapid reductions in carbon dioxide and carbon dioxide emissions are Other greenhouse gases will be needed by all sectors of society and the economy, "said Hoesung Lee, chairman of the IPCC.
Emissions are the main factor that determines the amount of greenhouse gases, but concentration levels are a measure of what remains after a series of complex interactions between the atmosphere, the biosphere, the lithosphere, the cryosphere and the oceans.
