A new study which came says that there is a decrease of 17% in the emission of carbon dioxide produced in the world due to the shutdown due to corona virus pandemic.

Scientists says that when the life of the people will come back towards normal after this pandemic shutdown, the cause of relief which is provided to the environment would be only a drop in the ocean, means it would not heal the environment to a large extent.

Scientists also calculated from the study of carbon emissions during the corona virus pandemic and said that there would be 4-7% drop in the levels of carbon emission which is still the largest drop since World War II.

It’ll be 7 percent if the strictest lock down rules remain all year long across much of the globe, 4 percent if they are lifted soon.

United States cut its carbon dioxide emissions by about one-third in a week in April. According to the study in the journal Nature Climate Change, China, which is the largest producer of carbon dioxide in the world cuts its emissions by about one-fourth. India and Europe cut emissions by 26 percent respectively. 

Study says that between April 4 and April 9 the world was producing 18.7 million tons of carbon pollution which is around 17 million metric tons a day which is less than the carbon emission on New Year’s day. 

Such low global emissions levels haven’t been recorded since 2006. Corinne LeQuere who is a lead author of a study and a climate scientist at the University of East Anglia warns that if the coming year would be the same as earlier in terms of pollution then this year’s temporary reduction would be similar to a drop in the ocean that will cause no healing effect to the nature on the whole.

She further said that this reduction would be like if you have filled the bath tub and turns the tap off for 10 seconds. Similar would be the case if the next year all the emission would be the same the earlier years.

The world carbon pollution levels had grown by 3.3 million tons which approxes nearly 3 million metric tons a day from its low point in the month of April compared to the month of March. These gases stays in the atmosphere for about a century.

Experts believes that the study shows us the damage we have done to the earth and it shows that too much of effort is required to prevent dangerous levels of global warming.

Michael Mann, who is a climate scientist at Pennsylvania State University said in an email that individual behavior would not lead us there and we need fundamental structural change. 

Study authors said that if the world could keep up annual emission cuts like this without a pandemic for a couple of decades, there’s decent chance Earth can avoid warming another 1.8 degrees of warming from now but getting these cuts annually would be very difficult and unlikely.

If the pollution levels returns to the same level which was in 2019, It means we have just given a 1 year gap to the warming of earth to extra 1.8 degrees, LeQuere said. We could reach the level anytime between 2050 to 2070, experts said.

Global Carbon Project which is a team of international scientists that produces annual estimates of carbon dioxide emissions. They calculated 450 databases which shows daily energy use and introduced a measurement scale for pandemic-related in its estimates.

The authors said that atleast half of the reduction came from the reducing of pollution from vehicles involving cars and trucks. In contrast, the study shows that reduction in pollution level from the air travel accounts for only 10% reduction in the total pollution drop.

California and Washington have seen the biggest declines in pollution which plunges about more than 40%.
