Because of extensive lock up during the pandemic in many countries of the world, notably Europe, USA, Brazil, China and India, there was reduced use of hydrocarbons, especially due to much reduced use of transport. Activities dimmed down the production sector and big companies; schools, markets and even prayer places remained closed. There have been reports that the quantity of GHG in the atmosphere showed reduction because of the lock up. Is it correct? If yes, has it been quantitatively evaluated and has its impact on global temperature for the eight months period assessed?

Yes, many studies surfaced assessing the effect of Covid-19 on the environment. Technically, I don't think so that it will affect the Global warming as a phenomena. But, it could be a case study for policymakers to assess more precisely the contributors to Global warming.
The global ecosystem is so complex that it is impossible to analyze with the signal element. I went through a study which shows a clear reduction in aerosol during Covid-19. Another study analyzed the greater penetration of UV due to a reduction in Aerosol.
It is obvious that due to lockdown, the transport industry becomes stagnant and a reduction is seen in Co2 release but the study shows that due to lockdown, the HFC gas release also increased due to extensive use of air conditioners.
So overall, there is an impact of Covid-19 on global warming but not enough to change the phenomena or shift the rising temperature trend by years. But it will create a bunch of data which can be helpful in future planning for battling Global Warming.

Thanks Mukhtar Ghani.
YEs, the HFC would have been released in greater quantity. But I feel that reduction in release of carbon dioxide would far outpace HFC icrease.
I do believe it is a bit soon to talk about it. When we are talking about the climate we are talking about the averages. Although there is some news about the changes in global warming because of changes in the rates of human activities, no one knows which scenario may happen in a few years: Would we come back to old routines? Would human activity increases because of the economic pressures or we should predict a stagnation point? etc.
Less transportation activity means less emissions (not from electric cars). However, the ice is still melting and the seas are much warmer than before, so the weather is more vicious. We have done nothing to improve the global warming that we had prior to cover-19.

Slight changes were observed in the climate , but the problem requires a more pronounced and marked anticipatory and global response, in addition to a world wide collaboration
COVID-19 is affecting the lives of millions of people and, also, the environment. The CO2 emissions and human mobility have been reduced, which improves air quality and encourages wild animals to come out and explore the cities
Due to lockdown during pandemic covid-19 pollution is reduced to a great extent thus improving air quality
Nature is observed as calm And unexploited which was seen never before
climatic changes are observed
warmth of the globe is reduced - a positive indication
I do think, air pollution has reduced and medical rubbish has increased.
Thank you for contribution---> Mukhtar Ghani, Arash Yoosefdoost, Michael Issigonis, Arvind Singh, Ray Alnaimi, S. M Bhat, Laith G. Shareef, Itishri Phadi, Md. Israt Hasa, and Md. Abdur Razaq Choudhury.
I saw pictures of snowy Himalaya taken from Jullandhar city, reportedly for the first time in decades because of clean air in the aftermath of the pandemic.
People have manipulated nature according to their needs from the very beginning of civilization. For that, air pollution, water pollution, climate change, ozone layer depletion, global warming, depletion of groundwater level, change of biodiversity & ecosystem, arsenic contamination, and many more are the effects of these manipulations. Global warming is a result of the increasing concentration of greenhouse gases (CO2, CH4, N2O, etc.).
In the long run, the pandemic will probably put a decreasing effect on global temperature due to partial or total lockdown at a certain period in almost all the countries in the world. The public gathering, traveling, various religious, cultural, social, scientific, sport, and political mass gathering events like Hajj, Olympics, etc. have been canceled in the current period. Some study found that maximum industries, production was not functioning, which have reduced waste emission, air pollution. Likewise, the shortage of vehicles on the roads have provided a low amount of greenhouse gas and toxin.
Moreover, the use rate of fossil fuels or conventional energy sources has lower so that ecosystems have been healed. Additionally, people visualized clear sky for the first time in big cities during the middle of this year, and the pollution level in tourist spots have also declined. Hopefully, the ozone layer may be recovered due to the reduction of pollution and greenhouse gas. Furthermore, Covid-19 is a pandemic situation for the whole world, but it created a very positive impact on the global environment.
I think COVID-19 has a greater impact on Global Warming, some impacts are visible some are none. The contributing factors of Global Warming (high CO2 emission, industries, auto mobiles etc.) became stand still during the initial stage of pandemic. That brought a remarkable change in our environment, if i talk about my own area. The rain fall was substantial, agriculture was good this year, the things catches the eye was fauna, I have seen different kind of birds which i thought was gone forever. However with the decreasing outbreak of COVID-19 the industries are opening with full rhythm and there are automobiles in the streets and the CO2 emission is increasing. Therefore COVID-19 teaches us many things which we need to give attention that which way will we go for our foreseeable future.
COVID-19 is affecting the lives of millions of people and, also, the environment. The CO2 emissions and human mobility have been reduced, which improves air quality and encourages wild animals to come out and explore the cities. But how sustainable is this positive effect in the long term? https://www.oneyoungworld.com/blog/what-effect-covid-19-climate-change
Studies have confirmed that air quality in certain regions has improved in recent weeks. As industries, aviation, and other means of transportation stop, air pollution is reduced countries severely affected by the virus, such as China, Italy, and Spain. A reduction in commuting due to work from home policies has also played its part in reducing carbon emissions. https://www.oneyoungworld.com/blog/what-effect-covid-19-climate-change
In the long term, the COVID-19 pandemic will offer lessons and opportunities leading to environmental action. For instance, we will have a new baseline of what can be achieved digitally: remote work, education, shopping, and more. In addition, as our governments, private institutions, and even social media succeed in partnering, we will possibly feel more capable of tackling other pressing issues such as climate change. Our response to this health crisis will shape how we will deal with a climate crisis in the next decades. Times of change can lead to the introduction of long-lasting sustainable habits. Thanks to the outbreak, some habits that are incidentally beneficial to the environment may last since people will have experienced scarcity. For example, the reduction of travel, personal consumption, and food waste. https://www.oneyoungworld.com/blog/what-effect-covid-19-climate-change
The worldwide disruption caused by the COVID-19 pandemic has resulted in numerous impacts on the environment and the climate. The global reduction in modern human activity such as the considerable decline in planned travel was coined anthropause and has caused many regions to experience a large drop in air pollution. In China, lockdowns and other measures resulted in a 25 per cent reduction in carbon emissions and 50 per cent reduction in nitrogen oxides emissions, which one Earth systems scientist estimated may have saved at least 77,000 lives over two months. Other positive impacts on the environment include governance-system-controlled investments towards a sustainable energy transition and other goals related to environmental protection such as the European Union's seven-year €1 trillion budget proposal and €750 billion recovery plan "Next Generation EU" which seeks to reserve 25% of EU spending for climate-friendly expenditure https://en.m.wikipedia.org/wiki/Impact_of_the_COVID-19_pandemic_on_the_environment
Dear M. Qasim Jan during the lockdowns and shutdowns caused by the COVID-19, it was possible to verify a sharp drop in emissions and pollution globally. When countries start 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.
I think global warming may decrease due to industrial crashing.
