The world is in lockdown and it鈥檚 dramatically affecting the climate. The reason? Across the globe, governments are slowing the spread of COVID-19 by imposing drastic .
As you know, in the UK we鈥檙e being told to stay at home, and only to go out for essential work, food or health reasons. Meeting up with others, even friends and family, is forbidden for the moment and we鈥檝e been told to stay two metres away from other people at all times.
These are uncertain and difficult times for us all, as individuals and as a society, but the effect the global restrictions have had on the climate is remarkable. In the space of just a few weeks, as people drive less and work from home where possible, we鈥檙e seeing improvements in air and water quality across the world.
Let鈥檚 have a look at just some of the regions in the world that are seeing change, from better air quality in London and Wuhan, to clearer waters in Venice and the Ganges.
Cleaner Air
Cleaner air in UK cities
London, Manchester, Birmingham and other cities across the UK have seen a huge decline in toxic nitrogen dioxide (NO2) levels, according to a study by the (NCAS).
Nitrogen dioxide is a harmful gas released when fossil fuels are burnt, usually by power plants and motor vehicles. Many of the activities that generate nitrogen dioxide are also responsible for the world鈥檚 carbon emissions and the current climate crisis.
Comparing recent pollution levels to the average from the same period in the previous five years, Professor James Lee from NCAS says: 鈥淭he air is definitely much healthier鈥�. You can see what he means in the chart below.

Director of Science at NCAS, Professor Ally Lewis, comments: 鈥淚n the midst of a respiratory health crisis such as this, better air quality can only have a small effect, but it will undoubtedly be positive [鈥 It is further motivation, as if it were needed, to stay inside and not travel unless necessary, since the emissions and pollution avoided makes a helpful difference.鈥�
Road traffic accounts for about 80% of nitrogen dioxide emissions in the UK, according to Paul Monks, Professor of Air Pollution at the University of Leicester, and former chair of the UK government鈥檚 science advisory committee on air quality.
The average diesel car spews out 52mg of polluting gas for every kilometre it travels, so it鈥檚 no surprise that the lockdown-induced reduction in traffic is leading to a substantial improvement in air quality.
Fall in pollution over northern Italy

As in the UK, Italy has significantly slowed economic and industrial activity, shutting all its shops except food stores, pharmacies and stores selling essential items.
Since the lockdown began in Italy on 9 March, satellite images taken by the European Space Agency have shown a dramatic drop in pollution in the skies over the north of the country, the area which is most densely populated and commercially developed. For example, the levels of toxic nitrogen dioxide around Milan, in Lombardy, have dropped rapidly.
Air quality improvements in Madrid
In Madrid, average nitrogen dioxide levels 聽week-on-week after the Spanish government banned all non-essential travel on 14 March.
Less polluted air over China

In late January, Wuhan was the first place in the world to introduce lockdown measures to deal with the emerging pandemic. NASA researchers began observing the environmental impacts of the restrictions聽and saw visible results. When they compared nitrogen dioxide values in 2020 with the average amounts from the same time of year from 2005-19, they found that
Clearer Waters
Visibly clearer water in Venice
It鈥檚 not just air quality that鈥檚 been improving. in those famously over-populated Venetian canals since Italy's efforts to limit the coronavirus have curtailed boat traffic.
A 2019 Venice by engineeringrome.org聽determined that dioxins from engine emissions had contaminated the canal waters, creating a 鈥渕urky contaminated mix鈥�. It suggested that 鈥渁ny decrease in traffic would help decrease the water pollution of the lagoon鈥� and improve the surrounding ecosystems.
And, owing to the restrictions caused by the COVID-19 pandemic, that鈥檚 exactly what鈥榮 happened.
It鈥檚 now safe to bathe in the Ganges
India began its own lockdown on 24 March when its 1.3 billion people were instructed to stay home. Since then, the health of the Ganges River has improved significantly.
According to the (CPCB), the lockdown has meant a reduction in industrial waste dumping. Readings of oxygen, biochemical and pH levels show the so markedly that the river water is now 鈥渟uitable for bathing and propagation of wildlife and fisheries鈥�. Previously, pollution levels had been so high that those activities had been deemed 鈥渦nsafe鈥�.
There is another way
The past few weeks and months have been extremely challenging for people and businesses, both in the UK and across the globe. The coronavirus pandemic is continuing to change the way we all live and work.
皇冠体育app hope that humanity can emerge from this awful situation having learned a lesson about our power to tackle the climate crisis.
The incredible bravery of key workers, fighting to keep us all safe, is inspiring 鈥� proving that we can all make a difference to our planet鈥檚 future by working together and supporting one another. 皇冠体育app鈥檙e all in this together.
皇冠体育app hope that we all can we carry this can-do mentality into the fight against climate change and build great lives for ourselves and each other in harmony with the climate.
