The largest hole ever observed in the ozone layer over the Arctic has closed, says Copernicus' Atmospheric Monitoring Service. Scientists spotted signs in late March of a rare hole forming and it was thought to be the result of low temperatures at the north pole.
Last year was the hottest in history across Europe as temperature records were shattered by several extreme heatwaves, the European Union's satellite monitoring surface said. In its annual report on the state of the climate, the EU's Copernicus Climate Change Service (C3S) said that 11 of the continent's 12 warmest years on record have been since 2000 as greenhouse gas emissions continue to rise.

Air pollution has decreased in urban areas across Europe during lockdowns to combat the corona-virus, new satellite images showed on Monday, but campaigners warned city-dwellers were still more vulnerable to the epidemic. Cities including Brussels, Paris, Madrid, Milan and Frankfurt showed a reduction in average levels of noxious nitrogen dioxide over Mar 5-25, compared with the same period last year, according to the Sentinel-5 satellite images.
Air pollution from nitrogen dioxide has fallen by an estimated 40% in three European cities, according to new satellite data released by the European Space Agency (ESA), coinciding with a widespread lockdown to curb the spread of the coronavirus.
By Gwynne Dyer – They teach you in journalism school never to use the phrase “…X has changed the world forever”. Or at least they should. Covid-19 is certainly not going to change the world forever, but it is going to change quite a few things, in some cases for a long time. Here’s eight of them, in no particular order.
The world’s water resources are under unprecedented threat. Today, some 2.2 billion people lack safe drinking water and 4.2 billion people live without access to adequate sanitation. Unless we act with urgency, the impacts of climate change are projected to exacerbate these figures. By 2050, between 3.5 and 4.4 billion people will live with limited access to water, with more than 1 billion of them living in cities.
On World Water Day, the United Nations launched a flagship report which says that reducing both the impacts and drivers of climate change will require major shifts in the way we use and reuse the Earth’s limited water resources.
