A New NASA Map Shows Spring Is Coming Earlier Each Year

Climate change is shifting Earth’s seasons. Winters are getting shorter, and the warmth of spring has started to arrive earlier and earlier, messing with the timing of processes like animal migrations and the budding of new plant growth. In a series of graphics spotted by Flowing Data, the NASA Earth Observatory shows how much earlier new leaves are arriving in some parts of the U.S., and how much earlier they reach full bloom.

The data comes from a 2016 study of U.S. national parks, so the maps only cover seasonal changes within the park system. But since there are so many parks spread across the U.S., it’s a pretty good snapshot of how climate change is affecting the timing of spring across the country. The map in green shows the difference in “first leaf” arrival, or when the first leaves emerge from tree buds, and the map in purple shows the arrival of the first blooms.

Around 75 percent of the 276 parks analyzed in the study have been experiencing earlier springs, and half had recently seen the earliest springs recorded in 112 years. In Olympic National Park in Washington, the first leaves are now appearing 23 days earlier than they did a century ago, while the Grand Canyon is seeing leaves appear about 11 days earlier. National parks in the Sierras and in Utah are seeing leaves appear five to 10 days earlier, as are areas along the Appalachian Trail. Some parks, however, particularly in the South, are actually seeing a later arrival of spring leaves, shown in dark gray in the graphic.

The places that are witnessing earlier first blooms aren't always the ones with extra-early first leaves. The Appalachian Trail is blooming earlier, even though the first leaves aren't arriving any earlier. But in other places, like Olympic National Park, both the first leaves and the first blooms are arriving far earlier than they used to.

“Changes in leaf and flowering dates have broad ramifications for nature,” National Park Service ecologist John Gross explained in the Earth Observatory’s blog. “Pollinators, migratory birds, hibernating species, elk, and caribou all rely on food sources that need to be available at the right time.” When temperatures get out of sync with usual seasonal changes, those species suffer.

The Richest Person of All Time From Each State


Looking for inspiration in your quest to become a billionaire? This map from cost information website HowMuch.net, spotted by Digg, highlights the richest person in history who hails from each of the 50 states.

More billionaires live in the U.S. than in any other country, but not every state has produced a member of the Three Comma Club (seven states can only lay claim to millionaires). The map spans U.S. history, with numbers adjusted for inflation. One key finding: The group is overwhelmingly male, with only three women represented.

The richest American by far was John D. Rockefeller, repping New York with $257.25 billion to his name. Amazon's Jeff Bezos and Microsoft's Bill Gates clock in at the third and fifth richest, respectively. While today they both make their homes in the exclusive waterfront city of Medina, Washington, this map is all about birthplace. Since Gates, who is worth $90.54 billion, was born in Seattle, he wins top billing in the Evergreen State, while Albuquerque-born Bezos's $116.57 billion fortune puts New Mexico on the map.

The richest woman is South Carolina's Anita Zucker ($3.83 billion), the CEO of InterTech Group, a private, family-owned chemicals manufacturer based in Charleston. Clocking in at number 50 is the late, great socialite Brooke Astor—who, though a legend of the New York City social scene, was a native of New Hampshire—with $150 million.

8 City Maps Rendered in the Styles of Famous Artists

Vincent van Gogh once famously said, "I dream my painting and I paint my dream." If at some point in his career he had dreamed up a map of Amsterdam, where he lived and derived much of his inspiration from, it may have looked something like the one below.

In a blog post from March, Credit Card Compare selected eight cities around the world and illustrated what their maps might look like if they had been created by the famous artists who have roots there.

The Andy Warhol-inspired map of New York City, for instance, is awash with primary colors, and the icons representing notable landmarks are rendered in his famous Pop Art style. Although Warhol grew up in Pittsburgh, he spent much of his career working in the Big Apple at his studio, dubbed "The Factory."

Another iconic and irreverent artist, Banksy, is the inspiration behind London's map. Considering that the public doesn't know Banksy's true identity, he remains something of an enigma. His street art, however, is recognizable around the world and commands exorbitant prices at auction. In an ode to urban art, clouds of spray paint and icons that are a bit rough around the edges adorn this map of England's capital.
