Paris: The past seven years have become the hottest in recording globally “with a clear margin”, the EU climate monitoring service reported Monday, because it raised an alarm on a sharp increase in methane concentrations in the atmosphere.
Countries around the world have been detonated by non-stop weather disaster attacks related to global warming in recent years, including forest fires that destroy recordings throughout Australia and Siberia, the Heatwave once-1000 years in North America and extreme rainfall which causes massively Floods in Asia, Africa, USA and Europe.
In the latest annual assessment, Copernicus Climate Change Service (C3) confirmed that 2021 had joined an uninterrupted warm line since 2015.
It was found that last year was the most warmer recorded globally, slightly warmer than 2015 and 2018.
Accurate measurement Return to mid-19th century.
The average annual temperature is 1.1 to 1.2 degrees Celsius above the pre-industrial level, measured between 1850 and 1900, the word C3S.
It was released from the cooling effect of the natural weather phenomenon of La Nina.
Overall, monitoring services found the last seven years “has become the hottest years in notes with clear margins”.
“2021 is another year of extreme temperatures with the hottest summer in Europe, a heat wave in the Mediterranean, not to mention high temperatures that have been unprecedented in North America,” said C3S Director Carlo Buontempo.
“These events are striking reminders about the need to change our way, take decisive and effective steps towards sustainable society and work to reduce clean carbon emissions.” C3S also monitors the concentration of gas atmospheric which warms the planet of carbon dioxide and methane, found that both of them increased without a slowdown sign.
Methane has mainly risen “very substantial”, for an annual record of around 1,876 parts per billion (PPB).
The growth rate for 2020 and 2021 is 14.6 ppb per year and 16.3 ppb per year.
It was more than double the average annual growth rate seen over the previous 17 years.
But various human sources caused and natural make it difficult to show why there is a strong increase in recent years, said C3.
Methane (CH4) is the most responsible gas for global warming after CO2.
While more short-lived in the atmosphere, this is many times stronger than CO2.
Natural sources include wetlands, while human-induced sources are leaked from natural gas and oil production, coal mining and landfill, and rice fields, livestock and manure handling.
Vincent-Henri Peuch, Director of the Copernicus Atmospheric Monitoring Service, which traces the increase in greenhouse gases, observational evidence is very important in an effort to avoid “climate disasters”.
Reducing the amount of methane that seeps into the air will quickly translate into a slowdown in temperature rise, and help close what is called the emission gap between the target of the Paris agreement on the closing 1.5C on the heating and 27C that we are headed even if all nations respect their carbon cuts appointments .
It has spur flowers from policy makers who want to find the fastest way to roll emissions.
At the COP26 climate summit last year, around one hundred countries joined the initiative to cut methane emissions at least 30 percent this decade.
Nothing is absent is Chinese.
The oil and gas industry has the greatest potential for rapid reduction, especially through detection and improvement of gas leakage during production and transportation.
While global warming may appear gradual, the impact on extreme events is “dramatic”, said Rowan Sutton, from the United Kingdom National Center for atmospheric science in Reading University.
“We have to look at the record of breaking 2021 events, such as heatwives in Canada and floods in Germany, as a blow on the face to make politicians and the public alike wake up with climate emergency urgency,” he told the Center for Science Media.
“Moreover, further increasing the concentration of greenhouse gases in the atmosphere screamed that the underlying causes have not been addressed.”
2021 is the fifth year-fifth earth, scientists said
