Scripps global O2 monitoring program showing a 91 ppm per year drop in atmospheric O2 since 1991

Oxygen levels are decreasing globally due to fossil-fuel burning. The changes are too small to have an impact on human health, but are of interest to the study of climate change and carbon dioxide. These plots show the atmospheric O2 concentration relative to the level around 1985. The observed downward trend amounts to 19 'per meg' per year. This corresponds to losing 19 O2 molecules out of every 1 million O2 molecules in the atmosphere each year.

Chart is graded in "megs" meaning number of units per total concentration, drop of 19 per million units per year translates at 20.95% concentration (209,500 ppm) to about 91 ppm total atmosphere per year loss of O2 while at the same time we're only gaining about 5 ppm per year of CO2. Combustion of hydrocarbon also bonds O2 to Hydrogen at a rate of 2 ppm moisture per 1 ppm O2. Oxidation of metals and materials counts down the O2 as well as creation and increase of Ozone O3. The differences in irregularity between Northern and Southern hemispheres reflect the disparate amount of wild fires, land mass and population but globally the O2 diffuses evenly across the planet.

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.

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...

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.
