CO2 LEVELS IN THE ATMOSPHERE IS 50 PERCENT HIGHER THAN 18TH CENTURY

Carbon dioxide levels within the atmosphere will this year reach levels 50 percent above before the economic revolution due to manmade emissions, Britain’s Met Office predicted on Friday. It forecasted the annual average CO2 concentration measured at the Mauna Loa Observatory in Hawaii in 2021 are going to be around 2.29 parts per million (ppm) above in 2020. It said CO2 concentrations will exceed 417 ppm at some point between April and June — 50 percent above the 278 ppm present within the late 18th century when the economic era began .

This is despite an unprecedented fall in greenhouse emission emissions in 2020 due to the pandemic.

The United Nations says emissions from energy, food production, transport and industry must fall quite seven percent per annum throughout subsequent decade so as to stay the temperature goals of the Paris climate deal live .

“Since CO2 stays within the atmosphere for a really while , each year’s emissions increase those from previous years and cause the quantity of CO2 within the atmosphere to stay increasing,” said Richard Betts, lead producer of the Met Office’s annual CO2 forecast.

“Although the Covid-19 pandemic meant that less CO2 was emitted worldwide in 2020 than in previous years, that also added to the continued build up within the atmosphere.”

Mauna Loa has been continuously monitoring atmospheric CO2 levels — which fluctuate consistent with season but still climb annually — since 1958.

The United Nations says emissions from energy, food production, transport and industry must fall quite seven percent per annum throughout subsequent decade so as to stay the temperature goals of the Paris climate deal live .

The 2015 accord enjoins nations to limiting heating to “well below” two degrees Celsius (3.6 Fahrenheit) above pre-industrial levels, and to 1.5C if in the least possible.

With just over 1C of warming thus far , Earth is already beset by extreme weather events like flooding, droughts and tropical storms supercharged by rising sea-levels.

The Met Office said it took around 200 years for CO2 concentrations to extend 25 percent since the economic era began.

“But now just 30 years later we are approaching a 50 percent increase,” said Betts. “Reversing this trend and slowing the atmospheric CO2 rise will need global emissions to scale back , and bringing them to a halt will need global emissions to be brought right down to net zero.”
