The Earth's atmosphere is a layer of gases encasing the planet, reaching above 10,000 km in altitude, with major divisions troposphere, stratosphere, mesosphere, thermosphere, exosphere. It contains about 78% nitrogen and 21% oxygen, and it protects life from harmful radiation while driving weather and climate dynamics; the stratospheric ozone absorbs UV radiation for protection against UV. Recent climate reports show CO2 rising, the record levels in hundreds of millennia, and continued warming and heat uptake in oceans, alongside reductions in polar ice.
Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The atmosphere has nearly 37.5 million billion gallons of water at any given time.
