Lockdown geen effect op global warming omdat we minder kolen branden

Je kunt het zo zot niet bedenken :roll:

They found that the drop off peaked in April, with CO2, nitrogen oxides and other emissions falling between 10-30% globally, mainly due to declines in surface transport.

But this new work shows that some of the declines in greenhouse gases actually cancelled each other out in terms of warming. Nitrogen oxides from transport normally have a warming impact in the atmosphere. While they went down by 30%, they were matched by a drop in sulphur dioxide, which mainly comes from the burning of coal. Emissions of this gas help aerosols to form, which reflect sunlight back into space and cool the planet. This balancing out, combined with the temporary nature of the pandemic restrictions, mean the impact on warming by 2030 will hardly be felt.

So what needs to be done to help that happen?

Study co-author Prof Corinne Le Quéré from the University of East Anglia says there are a number of steps that should now be taken.

"In cities, it is to support cycling and walking (including electric bikes) because this has multiple benefits for climate, for reducing air pollution, and for health," she told BBC News.

"Encouraging remote working until social distancing measures are lifted releases the pressure on public transport, which can continue to be used. As soon as possible all cars will need to be electric."

"The economic stimulus post-Covid could greatly help support that change in the car manufacturing industry towards the production of electric cars alone."

Prof Forster is optimistic that the challenge can be met.
