Un mur d’instruments braqués sur la planète et reliés à des données publiques libres et sans clé : une sismicité en temps réel que l’on peut entendre, une carte de la qualité de l’air qui respire au-dessus des villes, chaque nation classée selon la couleur de son drapeau, le graphe des frontières terrestres présenté comme une énigme, une espèce tracée sur toute son aire de répartition mondiale et une horloge où le soleil ne se couche jamais.
Raise the sea over a real coastline and watch it drown — live elevation, a slider from a storm surge to all the ice gone, and the percent of land lost.
A living radar loop — global precipitation tiles animated across the recent past into the next forecast minutes on a dark slippy map.
A live world map where every lightning strike on Earth flashes at its coordinates the moment a community detector network hears it.
Draw a line across the world and read its terrain cross-section — live elevations sampled along the path from the Copernicus DEM.
Live surface winds drawn as thousands of luminous streamlines, advected across the world from a grid of real-time Open-Meteo readings.
The live sunburn map — current ultraviolet intensity glowing over three dozen world cities, banded by the WHO scale and dimmed wherever night has fallen.
A live tide clock for U.S. coastal stations — today’s water-level curve, the next high or low with a countdown, and where the sea sits in its range right now.
A live thermal portrait of the world ocean — current sea-surface temperature read across a baked ocean grid and bloomed into a smooth field from polar deep-blue to equatorial red, with the warm pools, the Gulf Stream and the cold upwellings glowing through a masked-land map.
A live planet-wide rain radar — current precipitation sampled across a global grid and bloomed into a breathing blue field, with drops falling wherever the sky is actually wet right now.
Replay a month of the restless Earth — every quake of the last 30 days blooms in time order across a world map, sized by magnitude and tinted by depth.
A live portrait of the planet under cloud — current sky cover sampled across a global grid and bloomed into a breathing white field over the dark ocean, split into low, mid and high decks and creased by the day–night terminator.
The live auroral oval — NOAA’s OVATION model painting the ring of probable aurora around the magnetic pole, with the Kp index showing how far south it has slipped.
Chaque séisme récent tracé sur une carte du monde sombre et sonifié à l’instant où il survient — la planète clique et bourdonne en temps réel.
Le drapeau de chaque nation, lu pixel par pixel et disposé autour d’une roue chromatique selon sa teinte dominante.
Saisissez n’importe quelle espèce et regardez chaque observation enregistrée éclore sur une carte du monde sombre, révélant son aire de répartition mondiale.
Une carte du monde en direct de l’air respirable — la qualité de l’air actuelle tracée au-dessus des grandes villes sur l’échelle de couleurs de l’IQA américain.
Pick a city and find its climate doppelgängers — the places on Earth whose year of temperature and rainfall most resembles it.
Drop an ocean earthquake and watch the tsunami fan out across an embedded bathymetry grid — hourly travel-time isochrones refracting around continents and slowing over shelves, computed from the real shallow-water speed v = √(g·h).
Classify any city by the real Köppen–Geiger rules from its 12-month temperature and rainfall normals — read the code off the climograph, then warm the world a few degrees and watch the climate type itself migrate.
Watch the ring of warm light circle the live Earth — the subsolar point, the day/night terminator, civil/nautical/astronomical twilight, and the golden-hour band, all computed from solar geometry with no API.
Daylight hours computed exactly from solar geometry — a full-year heatmap across every latitude, a sunrise/sunset curve for the latitude you pick, and an axis-tilt knob that makes the seasons vanish or run wild.
Ed Hawkins' iconic barcode of climate: every year of the global temperature record as one stripe, blue past fading into deep-red present — scrub any year for its anomaly, flip to the line or decade view, and shift the baseline to watch the whole field re-zero.
Walk a point across the Whittaker diagram and watch mean annual temperature and rainfall decide which biome you stand in — then nudge the climate warmer and drier and see a forest migrate into grassland before your eyes.
Dig straight through the Earth and see where you come out — pick any point and watch its antipode land (almost always) in open ocean, with a cross-section through crust, mantle, and core and the classic 42-minute gravity-tunnel fall time.
The figure-8 the Sun traces if you photograph it at the same clock-time all year — built from the two physical causes (orbital eccentricity + axial tilt) that make a sundial disagree with your clock by up to ±16 minutes.
Un anneau tournant de deux douzaines de villes, chacune égrenant sa propre heure locale en direct, avec un marqueur mobile qui suit l’endroit où il est midi solaire sur Terre et celui où il est minuit — sur cette horloge, le soleil ne se couche jamais.
Une seule carte de chaleur des heures d’ensoleillement pour chaque jour de l’année et chaque latitude — les saisons, le jour et la nuit polaires, l’équateur plat, dessinés à partir de la pure astronomie.
Choisissez deux nations et trouvez le chemin le plus court entre elles le long de frontières terrestres communes — ou découvrez que la mer l’emporte.
