چکیده مقاله:

Climate change[۱] refers to long-term shifts in temperatures and weather patterns. Such shifts can be natural, due to changes in the sun's activity or large volcanic eruptions. But since the ۱۸۰۰s, human activities have been the main driver of climate change, primarily due to the burning of fossil fuels like coal, oil and gas. Burning fossil fuels generates greenhouse gas emissions that act like a blanket wrapped around the Earth, trapping the sun's heat and raising temperatures. The main greenhouse gases that are causing climate change include carbon dioxide and methane. These come from using gasoline for driving a car or coal for heating a building, for example. Clearing land and cutting down forests can also release carbon dioxide. Agriculture, oil and gas operations are major sources of methane emissions. Energy, industry, transport, buildings, agriculture and land use are among the main sectors causing greenhouse gases. The troposphere [۲] is the lowest layer of Earth's atmosphere. Most of the mass (about ۷۵-۸۰%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer. The troposphere is by far the wettest layer of the atmosphere (all of the other layers contain very little moisture). Air is warmest at the bottom of the troposphere near ground level. Air gets colder as one rises through the troposphere. That's why the peaks of tall mountains can be snow-covered even in the summer time. Air pressure and the density of the air also decrease with altitude upward to the tropopause, which is the boundary between the troposphere and the stratosphere. Because of these decrease in air pressure with height, the cabins of high-flying jet aircraft, which fly at the top of the troposphere, or often just above the tropopause in the more stable stratosphere, are pressurized. The system presented in this article suggests the use of outdoor coolers and the structure used as a honeycomb in cellular communication.
