NASA releases a series of images that reveal the devastating impact of a global disaster on our planet

The series of images from space, called "images of change", show changes from a combination of climate change, urbanization, floods and fires.

This includes shrinking Glaciers in New Zealand, snow in the Sahara desert, melting ice in Canada and reducing travel in Wuhan, China due to coronavirus restrictions.

                

                           

The collection consists of more than 500 images, including "before and after" footage taken weeks into decades, showing the reality of the impact of climate change on Earth.

A series of photographs show that Iceland's Oak Glacier has completely melted, and forest fires in Argentina and seasonal floods in Pakistan have flared up.


                        

Half of the photographs were taken before the event - in some cases four decades ago - and half of them show the same location after a major incident.

Arctic sea ice images taken between 1984 and 2020 show a marked change in the extent of the frozen region, showing the amount of melting in 36 years.



Researchers from the National Ice and Snow Data Center (NSIDC) say 2020 saw the second lowest stretch of arctic sea ice in the 42-year history of satellite records.

The record decline of Arctic sea ice occurred in 2012 -- the lowest level since satellite records began in 1979 -- but the 2013 minimum is larger, and the long-term downward trend has continued to be about 12% of sea ice per decade since the late 1970s.NSIDC's director, Mark Sears, said: "The ice shrinks in the summer, but it also gets thinner."

"At the rate we observe, summer sea ice in the Arctic is very likely to disappear completely during this century," said NASA scientist Joey Comeso.

As ice was shrinking in the Arctic, NASA recorded images of rare snowfall on the edge of the Sahara desert in December 2016.

NASA also took images of human events -- showing a significant decrease in traffic levels in Wuhan in early 2020 -- at the beginning of the Coronavirus pandemic.

The images were shared as an interactive exhibition on the NASA website. There are images from locations around the world, at different time points and divided into different categories covering ice, human influence, water and cities.
