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 Most Popular Halloween Candy in Each State

If you've ever argued that no one actually likes candy corn, you're probably not from Alabama, Iowa, Idaho, Michigan, New Mexico, Nevada, or Rhode Island. The controversial confection is a favorite treat among residents in those states, according to sales data from online candy retailer CandyStore.com.

As they've done for more than a decade, the bulk candy retailer combed through 11 years of data (with a particular focus on the months leading up to All Hallows' Eve) to gauge America’s top-selling sweets. They created the interactive map below to display their results.

In addition to the divisive—yet classic—candy corn, Skittles, M&Ms, Snickers, Reese's Peanut Butter Cups, and Starburst were among the nation's favorite candies. Hot Tamales, Tootsie Pops, Jolly Ranchers, and Sour Patch Kids have all earned some candy lovers' devotion, too.

Some states are unique in their top candy choices: Mississippi was the only state to name 3 Musketeers the best, while Connecticut opted for Almond Joy and West Virginia showed their love of Blow Pops. Meanwhile, trick-or-treaters in Kentucky have a sweet tooth for Swedish Fish, Louisianans love Lemonheads, and Delawareans would die for Life Savers.

After seeing which treat is number one in your state, check out the chart below to learn how many pounds of each top-ranking candy are consumed in each state (and then go buy a new toothbrush).

The '90s PBS Shows We're Still Talking About Online, Mapped

Were you a Barney kid or an Arthur kid? Or maybe you were obsessed with the Teletubbies instead? Or maybe you're still that kid inside, off making PBS memes as an adult. You're never too old to appreciate public television's kids programming, if the recent box office success of the Mister Rogers documentary Won't You Be My Neighbor? is any indication.

Knowing that today's adults still have a soft spot in their hearts for the PBS shows of their childhoods, the telecom sales agent CenturyLinkQuote.com used Google Trends to figure out what kind of impact different kids' series had on each state. They created the map above, showing the most talked-about PBS Kids show in every state over the last 14 years.

According to this data, the Midwest is all about Reading Rainbow, Sesame Street is big in New Jersey and Delaware, and Wishbone reigns in the Southwest. Mister Rogers, despite his status as a TV icon, only dominates in Pennsylvania. The short-lived Canadian-American show Zoboomafoo makes a surprisingly strong showing, coming in as the favorite in four different states despite only having two seasons.
