The European Space Agency has revealed, a new unusual hole in the ozone layer has started to form over the Arctic.
According to ESA, the ozone layer over the North Pole has been depleted plenty of times in the past. Scientists using data from the Copernicus Sentinel-5P satellite have noticed a strong reduction of ozone concentrations over the Arctic.
Unusual atmospheric conditions, including freezing temperatures in the stratosphere, have led ozone levels to plummet—causing a ‘mini-hole' in the ozone layer.
Chicago’s crime declined 10% after the pandemic struck, a trend playing out globally as cities report stunning crime drops in the weeks since measures were put into place to slow the spread of the virus.
Much of the decrease has taken place because of tougher security policies and gang truces. But the imposition of near-total limits on movement is likely driving it down further.
In South Africa, police reported a stunning decline during their first week of lockdown measures.
El Salvador reported an average of two killings a day last month, down from a peak of 600 a day a few years ago.
Geographic information system (GIS) used to track cyclones, floods and other natural disasters is now being used by some states to understand the spread of the Covid-19 pandemic and the unprecedented challenges presented by it.
To tackle the pandemic, the company has created a special ArcGIS Hub coronavirus response template that can be plugged into its existing products like the ArcGIS Online and ArcGIS Pro.
The ESRI template lets authorities create dashboards and interpret the data overlaying them on maps. On top of this, analytics can be run showing what is contributing, for instance, to higher rates of fatality.
