From melting ice and snow to blooming trees and flowers, chances are you've probably seen subtle signs of spring taking shape in the last couple of weeks. Some of the changes we are seeing can also be viewed on a larger scale from satellites in space.

In the South, increasingly warm tempartures and recent rains have given the landscape a much greener look. NASA's Terra and Aqua satellites show the subtle change from brown to green that has occurred in parts of the South from mid-March into early April.

This before and after comparison shows how parts of Oklahoma, Texas, Louisiana and Arkansas are much greener as of early April compared to mid-March.

Farther north, it's a bit too early to see the landscape turning green. However, we can see spring emerge by watching the ice melt on both the Great Lakes and smaller lakes in the Midwest and Northeast.

The before and after satellite images below show how much the ice has decreased on Lake Erie from March 9, 2015-April 4, 2015. During this period of time, ice coverage on Lake Erie has decreased from 92 percent to about 53 percent.

This before and after comparison shows how ice has decreased substantially on Lake Erie from early March into early April.
