The Noval Coronavirus epidemic rapidly reduces carbon dioxide levels and air pollution.
As the Coronavirus spreads and affects work and travel around the world, carbon monoxide has been reduced by about 50% since last year.
Reduction in the use of cars has helped to reduce levels of gases such as CO2 And sulfur dioxide.
Carbon dioxide emissions, which cause global warming, have also decreased dramatically.
However, after an outbreak, emissions levels may increase rapidly according to the warnings.
Given that the Coronavirus epidemic slows down global economic activity, it is not surprising that energy emissions and transport of different gases have decreased.
When carbon dioxide emissions reach their highest levels in May, the level of securities may be the lowest since the financial crisis ten years ago, scientists say.
According to data collected in New York this week, guidance on unnecessary travel restrictions has a major impact.
Columbia city researchers say city traffic levels are 35% lower than a year ago. Carbon monoxide emissions, especially from cars and trucks, decreased by about 50-50% on some days this week.
They also found a 5-10% decrease in carbon dioxide and a significant decrease in methane compared to New York.
“In the past 18 months, there has been an abnormal level of carbon monoxide in New York,” said Professor Rayon Suncom of Columbia University, who works in New York.
“This is the cleanest I’ve seen so far. This is less than half of what I usually see in March.”
These results reflect the environmental impacts of the virus outbreak in China and Italy, although there are several anomalies.
In a two-week period in China, energy consumption and emissions have decreased by 25%, according to an analysis by the carbon website. They estimate that, as a result, China’s carbon emissions will decrease by 1% this year.
In China and northern Italy, a significant decrease in nitrogen dioxide has been recorded in relation to low vehicle travel and industrial activity. Gas is not only serious air pollution but also a heating system.
In many countries, millions of people are likely to follow the same streak in a series of emissions, as work from home and planes stops.
However, since people work from home, there is a possibility of increased heating and electricity consumption in the home, but the overall slowdown in travel and savings is likely to affect overall emissions.
Professor Kamai said: “I hope we have the lowest growth in the months from May to May, which is the peak of carbon dioxide we have achieved in the Northern Hemisphere since 2009, or even before that. Is.”
Those who believe the closure will affect carbon dioxide levels throughout the year echo this view.
“The epidemic will depend on the duration of the disease and the extent of the economic recession, especially in the United States. But it is very likely that you think we will see something in global emissions this year.” The University of East Anglia.
“If it continues for another three or four months, we can definitely see some decline.”
How governments should decide to restore their economies after the outbreak has made a huge difference in the extent of carbon emissions and air pollution.
After the global financial meltdown in 2008-2009, carbon emissions increased by 5% due to the stimulus costs that led to the use of fossil fuels.
However, in the coming months, governments will have an opportunity to change this outcome. For example, they may insist on linking a significant reduction in aviation emissions to any airline rescue plan.
“Governments should now be very careful about how to revive their economies, keeping in mind that fossil fuels are not closed,” said Professor Le Kerry.
“They should focus on ready-made items that will reduce emissions, such as renovating buildings and installing heat pumps and electric chargers.” It’s not complicated and can be done right away, they just wait for financial incentives. “
However, some argue that if the epidemic lasts for a long time, any incentive is likely to focus on fostering any economic growth, regardless of the impact on the environment.
“I certainly think that the climate can be in the background, and in this case, I don’t think there is much hope for the catalyst to go into clean energy,” said Professor Glenn Peters of the Center for International Climate Research.
“Any incentive will help those who lose jobs like tourism and services. I think it’s completely different from the global financial crisis. The only positive thing is learning new practices for telework and buying a few years of weaker growth that allows solar energy and wind energy can catch up a little bit, can Silver layers are very small. “
