What Doesn't Stay in Vegas? Sprawl.

Las Vegas has undergone a massive growth spurt. This image series, created in honor of 28th birthday of Landsat 5, shows the city sprawling across the desert. The outward expansion of Las Vegas is shown as a false-color time lapse from all 40 years of Landsat satellite data.

The large red areas are actually green space, mostly golf courses and city parks. The images become a lot sharper around 1984, when new instrument designs improved the ability to resolve smaller parcels of land.

These images were created using reflected light from the near-infrared, red and green portions of the electromagnetic spectrum (Landsat 5 TM bands 4,3,2 and Landsat 1-3 MSS bands 4,2,1).

Landsat data have been instrumental in increasing our understanding of forest health, storm damage, agricultural trends, urban growth, and many other ongoing changes to our land.

NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images with freely available data over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for a launch in January 2013.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

How Cold Can It Get? The Lowest Temperatures Ever Recorded, Mapped

We often talk about record heat , especially in the context of climate change. But on the flip side, our planet also experiences cold so extreme it defies belief—temperatures that can flash-freeze exposed skin and halt life as we know it. These are not just numbers on thermometers; they’re snapshots of how Earth's atmosphere behaves under specific conditions—altitude, wind patterns, and location far from the moderating effects of oceans. The coldest temperature ever recorded on Earth? That title goes to Vostok Station in Antarctica, where scientists measured a bone-cracking −89.2°C (−128.6°F) on July 21, 1983. Located on the East Antarctic Plateau, Vostok is more than 1,000 kilometers from the South Pole and sits atop about 3.7 kilometers (2.3 miles) of ice. It’s isolated, dry, and high—three ingredients that make for perfect deep freeze conditions. The world map below created by VividMaps shows the lowest temperature ever recorded by country.

Mapping the Hottest Temperatures Ever Recorded on Earth

When summer arrives, it brings not only vacation season but also some of the most extreme heat waves across the globe. While many people associate summer with warm, sunny days, some regions endure scorching temperatures that push the limits of human endurance. To put these extremes into perspective, we’ve mapped the highest temperatures ever recorded in countries around the world. The maps below, created by Vivid Maps , illustrate these record-breaking temperatures and the patterns of extreme heat across the globe. The Hottest Temperature on Record According to historical weather data, the highest reliably recorded temperature on Earth is 56.7°C (134°F) , measured in Death Valley, California , on July 10, 1913 . However, an even higher temperature of 58°C (136.4°F) was reportedly recorded in El Azizia, Libya , on September 13, 1922 . While this Libyan record stood for decades, some meteorologists have questioned its accuracy due to inconsistencies in measurement methods at the ti...
