Whether you choose to look at temperatures at Earth’s surface or higher up in the atmosphere, nine of the 10 hottest years on record have now occurred in the 21st century. A tropospheric record WebThe Earth's atmosphere is divided up into a number of layers (troposphere, stratosphere, etc.) based upon the variation in temperature with elevation within that layer. The troposphere (closest to the Earth's surface) has a large negative temperature gradient, decreasing from about 15° C at the Earth's surface to about -50° C at the top of the …
