In many countries, air and rail transportation is interrupted. The isolation measures lead to the decrease of road traffic utilization and the production of factories. The result is reduced carbon emissions and clean air above China, South Korea, European countries and the United States. China's anti epidemic measures have reduced carbon emissions by 25% in just one month. At the end of March, the European Space Agency (ESA) released satellite images showing changes in the ozone layer over many countries between January 1 and March 11. The changes above Italy are particularly dramatic, with the country's ecological indicators improving, as seen by the naked eye: swans and fish begin to return to the Venetian canal, and then dolphins and jellyfish are observed.
Restricted movements with less number of motor vehicles , less activities, closed factory with less carbon and other harmful gases, less destruction of biodiversity and ecosystem: green environment with less pollution.
The question is how long this green will persist!
Significant effects have been seen during lockdown. You can refer these papers (attached).
The lockdown during this pandemic has contributed to reducing air pollution and hence climate change effects.
Lockdown due to Corona has changed the total environment for a while.
It's challenging to maintain the green environment in our normal life after the lockdown.
The good thing with the COVID19 pandemic has no pollution at all and that contribute to global climate change.
Very interesting .
There are more interesting questions one would like to answer, such as !!

COVID-19 has improved environmental pollution. Industries, transportation and aviation have been reduced/stopped, as such carbon emission has dropped. At the same time, COVID-19 has taught us lessons on long lasting sustainable habits. Hopefully, such habits which are beneficial for the environment may last, so that we will be more capable of tackling the future effects of climate change. And then only we will be able to deal with climate crisis in the coming decades.
Dear Xiuqiang Liu During the lockdowns and shutdowns caused by the COVID-19, it was possible to verify a sharp drop in emissions and pollution globally. Now that countries started to work on restarting their economies, the sustainability criteria must be the core of our recovery efforts to maintain our course towards a climate-resilient low-carbon transition, rather than continue the previous vicious cycle of environmental degradation, biodiversity loss, and zoonotic infectious disease outbreaks. Kind regards, Ernani
The reduction in emissions is great, however, the ocean is still warmer than normal, therefore, this years' hurricanes and typhoons were ferocious, deadly and are multiplying in numbers.
The oceans need to cool down to show any difference in global warming. We can't help there. Besides the emissions, the increase in global humidity drives the global temperature higher. Here we could do something about it. We could remove the humidity from the air probably easier than remove the CO2 from the air.
