International Day for Biological Diversity
International Day for Biological Diversity
Today we"re celebrating the biodiversity of our planet. What exactly is biodiversity? It refers to the variety of living things, from animals and plants to fungi and microorganisms, in one area. This delicate but vigorous balance in nature is what keeps us all alive. That"s definitely worth celebrating! May 22 was named International Day for Biological Diversity by the United Nations in 2000. Unfortunately, the biodiversity of Earth is slowly decreasing due to climate change, the draining of natural resources, urbanization, and pollution, among other factors. Campaigners are urging governments, businesses and individuals to take action to boost biodiversity, to protect healthy ecosystems that supply us with water, food, medicines, and more. After all, we are blessed with intriguing species such as the Tasmanian snow gum—the tree seen in today"s image—that takes root in one of the most biologically diverse places on the planet, the Mount Field National Park in Tasmania, Australia.Desktop Version
Medieval towers in Mestia, Upper Svaneti, Georgia
Medieval towers in Mestia, Upper Svaneti, Georgia
Winter turns Mestia"s medieval towers into icy fortresses. Perched 4,921 feet up in the Caucasus Mountains, Mestia is a charming highland town in northwest Georgia. The town is home to the Svans, a cultural and linguistic subgroup of Georgians. Despite its modest size, Mestia has been an essential hub of Georgian culture for centuries, dotted with the Svan defensive towers, seen in today"s image. Most of these towers were constructed between the 9th and 12th centuries, a period often referred to as Georgia"s Golden Age. However, their roots are believed to stretch even further back, possibly into prehistoric times. Built for both protection and shelter, these towers were not just fortresses but also integral parts of family homes, reflecting the region"s history of resilience and self-sufficiency. Therefore, it isn"t just a town; it"s a living museum where history rises from these towers and echoes through the mountains.Desktop Version

International Day for Biological Diversity
International Day for Biological Diversity
Life on Earth, from tiny bacteria to towering trees, is interconnected. International Day for Biological Diversity is about celebrating this web of life that keeps our planet thriving. Biodiversity ties into everything, from sustainable farming and clean water to climate action and disaster preparedness. A decline in biodiversity can increase the spread of zoonotic diseases—those transmitted from animals to humans. In contrast, protecting biodiversity strengthens our ability to prevent and respond to health crises like pandemics. Recognizing its crucial role for current and future generations, the United Nations observes this day each year to raise awareness and foster action for conserving the planet"s biological treasures.Desktop Version
Grandparents Day
Grandparents Day
Have you called your nana, abuela, pop-pop or lolo lately? No matter what you call them, there"s no better time to pick up the phone than Grandparents" Day, held on the Sunday after Labor Day.

Perhaps that"s why these Atlantic walruses look like they"re about to tell you why they voted for Hubert Humphrey.Desktop Version

Frankenstein Friday
Frankenstein Friday
Picture yourself at the highest peak in the Alps, where the air is crisp and the views are breathtaking. The towering presence of Mont Blanc has left an indelible mark on literature, most notably on Mary Shelley"s "Frankenstein." The last Friday of October is Frankenstein Friday, honoring Shelley"s literary genius and the fascinating creature born from her imagination. "Frankenstein" was conceived during a ghost story challenge. In 1816, an 18-year-old Shelley, along with fellow writers Percy Bysshe Shelley, John Polidori, and Lord Byron, spent a stormy summer in Switzerland. Forced inside by incessant rain, she penned the tale of Victor Frankenstein and the Creature. A pivotal scene in the novel takes place on a glacier near Mont Blanc, where Victor is confronted by his monstrous creation. This setting, with its surreal beauty and treacherous terrain, perfectly captures a sense of awe and terror.Desktop Version

World Meteorological Day
World Meteorological Day
"When clouds appear like rocks and towers, the Earth"s refreshed with frequent showers." There"s a whisper of truth to this old proverb for the storm clouds, also known as cumulonimbus or anvil clouds, which are pictured here. Today, on World Meteorological Day, we honor the marvel that is our atmosphere. This observance, first held in 1961, commemorates the establishment of the World Meteorological Organization and recognizes the vital role meteorology plays in our lives. Weather forecasts may not always appear reliable, but thanks to advances in technology like satellites and supercomputers, they have come a long way. Global weather models provide forecasts for up to 16 days and, the average lead time for tornado warnings is now around 15 minutes. Cheers for the progress made and much more to come!Desktop Version
Daylight saving time begins
Daylight saving time begins
It"s the time of year again when clocks spring forward, stealing an hour of sleep but giving us longer evenings to enjoy. Daylight saving time (DST) starts today at 2 AM, except in Arizona and Hawaii, reminding us that time, quite literally, waits for no one. The idea is simple: maximizing daylight and reducing energy consumption by syncing our activities with the natural light cycle. This concept was popularized by Benjamin Franklin in the 18th century, though his suggestion to "save candles" was more satirical than a serious proposal. Fast-forward to the early 20th century, when many countries adopted DST to conserve fuel during wartime. The US officially standardized it in 1966 with the Uniform Time Act. Today, DST runs from March to November in around 70 countries, giving eight months of extended evening light.Desktop Version
The Sonoran Desert, Arizona
The Sonoran Desert, Arizona
Welcome to the Sonoran Desert, where life thrives despite the heat thanks to two seasons of rainfall. This subtropical desert spreads across parts of Mexico, California, and Arizona and is home to animals such as roadrunners, Gila monsters, and the Morafka"s desert tortoise. Its rainy seasons are followed by the blossoming of colorful wildflowers such as the brittlebush, seen in today"s image. These hardy shrubs are adapted to the dry seasons, with their silvery-gray leaves covered in fine hairs that help reduce water loss. Brittlebushes produce bright yellow flowers that bloom in clusters, adding splashes of color to the desert landscape. Another drought-loving desert flora is the saguaro cactus, which can live for over 150 years and grow up to 40 feet tall. The saguaro also provides food and shelter for desert species and is a sacred plant in the culture of the Tohono O"odham people.Desktop Version

Take a stroll along almost any marina from Costa Rica to Alaska, and you"ll likely hear the playful barks of sea lions echo through the air. California sea lions, like the one pictured, are a common sight basking in the sun along the rocky shores of North America"s western coast. These marine mammals, belonging to the pinniped group, are often mistaken for seals. An easy way to distinguish between them is by looking at their ears—sea lions have visible flaps, seals don"t.Desktop Version

European river otter, Netherlands
The European river otter is more than just an adorable face in the wild. Found across Europe, Asia, and parts of northern Africa, these otters thrive in clean rivers, lakes, and wetlands, serving as an important indicator of environmental health. They are built for agility, with streamlined bodies, webbed feet, and dense fur that keeps them warm even in icy waters. A single square inch of their fur can hold more than 400,000 hairs, making it one of nature"s most effective insulators. River otters were once endangered due to pollution and habitat loss. Thanks to conservation efforts, their populations are rebounding in many regions across Europe.Desktop Version

Star Wars Day
Star Wars Day
May the Force be with you on May 4, adopted by "Star Wars" fans as the day to celebrate their favorite franchise. Many will recognize Skellig Michael, the island on our homepage, as the location of scenes from the "Star Wars" sequels, "The Force Awakens" and "The Last Jedi." This UNESCO World Heritage Site appears in the movies as the planet Ahch-To, where Jedi master Luke Skywalker seeks refuge. Home to a 6th-century monastery with beehive huts and stone staircases, it also hosts a large seabird population that inspired the penguin-like porgs that roost on Ahch-To. Skellig Michael is about 7 miles off Ireland"s southwestern coast, daily visitors are limited, and boat trips are canceled if it is too stormy.
