Although the reopening of many people are welcome, are climate scientists worried about how fast emissions of CO2 are returned.
When the shutdown was at its peak, the decrease of the global CO2 pollution by 25 percent - up to 40 percent in Danish cities - compared to the same period in 2019.
Now is the global pollution is only 5 percent lower than the year before, according to climate scientists.
'It's gone very quickly. Very few countries still have strict restrictions. We expected that the pollution would return, but it is gone so quickly is very surprising,' says Corrine Le Quéré, professor of climate change at the University of East Anglia to The Guardian.
Several places in the world gave it visibly cleaner air, when it was shut down in march. See the wild difference here. Video: Reuters.
The less CO2 emissions for the year up to now represents a decline of 8.6 percent compared to the year 2019, is not enough to approach it, there is a need for in relation to the Paris agreement.
During the crisis, governments urged to limit the public transport, which also now get more to prefer the car and the busy roads.
Le Quéré call it a disaster, if kørevanerne returns to normal, and more fear that the pollution may be worse than usually, when people are encouraged to keep away from public transport.
Several researchers suggest that the governments of the world have a golden opportunity with the stimulus plans to switch to a CO2-friendly infrastructure. But it is a race against time, " says the professor to The Guardian.
By the end of the year it may be too late.
