WebbIt’s important to remember that scientists always focus on the evidence, not on opinions. Scientific evidence continues to show that human activities (primarily the human burning of fossil fuels) have warmed Earth’s surface and its ocean basins, which in turn have continued to impact Earth’s climate.This is based on over a century of scientific evidence … The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, creating ions; the thermosphere thus constitutes the larger part of the ionosphere. Taking its name from the Greek θερμός (pronounced thermos) me…
Webb16 maj 2024 · When averaged globally (see the left column of Figure 1), ΔTn shows thermosphere cooling up to −60 K above 200 km height, along with a density reduction (Δρ) of 40–60%.Positive ΔTn of 5–10 K occurs between about 110 and 150 km altitudes, coinciding with a minimum in Δρ.When unfolded in latitude (see the upper right panel), … WebbFurthermore, high-latitude joule heating, which is a source of energy input to the thermosphere, is affected by solar wind conditions as well as geomagnetic activity [4,5]. During geomagnetic storms, the enhanced high-latitude joule heating causes thermal expansion of the thermosphere, which in turn causes disturbances in mass density.
