HARRISONBURG, Va. (WHSV) -- While this past winter was cold, it wasn't just that way in the Valley.
According to NASA's temperature data, it was very cold all along the eastern half of the United States; however, if it's cold in one place, that means it's warm somewhere else.
This winter, the western half of the county, including Alaska was warmer than usual.
NASA scientists continue to track global temperatures and right now, around the Earth, there are 19 different spacecraft tracking changes in patterns around the globe.
According to their research, there are some noticeable changes with the growing season length and the timing of the frost free dates.
"It's five days earlier in the spring when plants start to grow, but in the fall it's also and five days longer. So the growing season in the past 60 years has lengthened in North America by 10 days," said Dr. Compton Tucker, a NASA scientist.
A few days may not seem like a lot. and one of the bigger effects of a longer growing season is snow pack.
Snow can melt a little sooner leading to drier conditions at the end of the summer increasing the potential for wildfires.
Although the trend has been toward a longer growing season in the past 60 years, NASA has only had their weather satellite program since the 1950s.
NASA also has a free app that you can download called Earth Now. It's a visualization of current climate data in a 3D global map.
NASA is known for their incredible images and now you can get current data right on your phone.
