NEW NASA SURVEY FINDS ANTARCTICA COVERED IN MORE ICE THAN PREVIOUSLY THOUGHT

Antartica is one of the most ice-covered locations in the world, but it is also one of the world’s largest land masses. Previous estimates by researchers placed the level of uncovered land in Antartica at about 1%. However, a new survey in part by NASA shows that this estimate was rather generous and the continent is covered in a lot more ice than previously thought. Researchers from Cryosphere have shown that only.18 percent of the entire continent is not covered by ice and snow, which is surprisingly low. With this new figure, researchers will monitor this survey over time to see the effects of climate change and global warming.

“With effects ranging from influencing ocean currents to raising sea level, Antarctica plays a large role in the global climate system. Researchers are using a variety of methods to understand how Antarctica will react to a changing climate, but limited information on ice thickness and what lies beneath the ice makes this work challenging.” ~ NASA

This new research has been put off for a while, and it may surprise you that this is the first time we have had an accurate representation of Antartica’s land mass. Automated techniques were used in the new study to allow seamless data collection as well as the automatic removal of clouds over the continent to make the snow and ice readings more accurate. The NASA and US Geological Survey satellite was used for the new study, which corrected previous ice and snow calculations in comparison to land mass.

  1. Did people from the past ever worry about this kind of stuff?
    It’s like a story I read a while back that used an illustration of a glass of water filled with ice, and then asked the question; ‘does the cup overflow when the ice melts?’ The answer was no, of course. So, if the polar ice melts, will the world flood over? I believe, no. I truly hope these mother earth people would get a true grasp of reality and search out a more life saving worthy cause that would actually help the destitute they are clamming to help.
