Sad update for Google Earth. Timelapse shows how the planet has changed

New in Google Earth It is primarily concerned with the need to educate people about climate change. Over 24 million satellite images, taken between 1984 and 2020, were used to create a Timelapse. In total, they created a time-lapse video with a resolution of 4.4 Teraxel (the first treatment is a million megapixels). Thanks to this, it is possible to track geographical changes that occurred in the long run.

In addition to the Timelapse feature update, The Google It released 800 time-lapse movies from different regions around the world, 290 of which were supplemented with 3D copies.

A third of the Antarctic shelf could collapse into the ocean. Four degrees Celsius is enough

On, we cited the results of a study by scientists from the University of Reading in England showing how the Antarctic ice shelf (i.e. the marginal portion of the ice sheet is no longer present on the ground, but in the water) of climate change. As they explain, this is the most detailed study conducted to date.

According to the researchers’ analysis, the proportion is 34 percent. Of all the Antarctic ice shelves, they are in danger of bursting into the ocean if the average temperature on Earth rises to 4 ° C above pre-industrial levels. Today it is snow covering an area of ​​nearly half a million Kilometers Square. Moreover, 67%. From this ice is the Antarctic Ice Shelf.

The researchers also considered a more optimistic scenario. A temperature rise of 2 ° C (instead of 4) will reduce the area of ​​ice at risk of injury by half. Hence, of course, this means a much smaller increase in ocean level.

Scientists have also identified four ice shelves that are particularly vulnerable to destruction. These are Shackleton, Pine Island, Wilkins, and Larsen C. Much of the ice (about 10% of the total) separated from the last one in 2017, creating the A68 iceberg of roughly 6,000. How many Tadalafil. Even in December 2020, it threatens South Georgia Island and the local ecosystem.
