Global warming is currently one of the greatest challenges to humanity. So far, the attempts to mitigate global warming have been based exclusively on the reduction of carbon dioxide concentration in the atmosphere. The main methods include reduction of CO2 emissions and the removal of carbon dioxide from the atmosphere, as in the case of carbon capture and storage. One of the problems with this approach is that the lifetime of CO2 in the atmosphere is very long and the effect of the CO2 emission reduction on atmospheric temperature decrease will only become meaningful after a number of decades. In this work I am proposing to reduce the global atmospheric temperature increase, or even to decrease the temperature by removing sensible heat from the atmosphere and transferring it to media outside the atmosphere such as water or land mass. One of the main advantages of atmospheric heat removal is that unlike CO2 emission reduction, it has an immediate effect on atmospheric temperature. Also, the technology is simple, inexpensive and relatively well developed. Four different methods to achieve that are proposed: one by direct heat exchange between the atmosphere and cooling water, and the other three based on the process of isothermal gas compression and expansion. The latter three methods combine the cooling of the atmosphere with other practically important features: energy storage, energy transport and power generation. Proven patented technical solutions to achieve the atmospheric cooling are shown. The energy balance and the financial and materials requirements to build the needed equipment show that the complete stop of global warming is achievable in a period of several years. It should be noted that the proposed solution to global warming is temporary and will work only for several decades. In the longer term, CO2 emission decrease (which needs to start as soon as possible) should take over as the main method of global warming mitigation. INTRODUCTION The process of chemical fuel oxidation involves two significant types of emissions to the environment: mass (primarily carbon dioxide and water vapor) and energy (sensible heat and some electromagnetic energy in the infrared and visible spectrum) 1 .

In it the Chief Editors state: "From time to time, we receive submissions at Earth System Dynamics claiming that global warming, or at least a significant part of it, is caused by factors other than the direct and indirect effect of anthropogenic greenhouse gas emissions. A number of these submissions claim that the increase in observed temperatures is due to the emission of heat from human activities… Such submissions would not have passed peer review in Earth System Dynamics as they ignore basic textbook knowledge and would indeed typically be rejected prior to entering the open-discussion peer review phase." It should be emphasized that discoveries "ignoring basic textbook knowledge" are among the strongest drivers of science (Newton, 1687; Einstein, 1905; Galilei, 1590) and should not be ignored unless they are deemed incorrect. And the determination of their correctness is performed in a peer-review process. On a smaller scale, it was recently found that the assumption that the motion of free rising and free falling rigid bodies are governed by the same physical principles (Newton, 1687; Galilei, 1590) was incorrect (Karamanev and Nikolov, 1992). While this discovery was "ignoring basic textbook knowledge" at the time, the peer-review process confirmed that Galileo and later Newton were wrong in that regard (mainly because the phenomena of turbulence was unknown at their respective times), and the new discovery is now part of the mainstream knowledge base (Green, 2008; Chhabra and Basavaraj, 2019). Further, the Editorial states: "A quick look at the global surface energy balance illustrates this clear picture: human primary energy consumption amounted to 595 EJ in 2021 (BP, 2022), which translates into an average heat release of 18.9 TW. When averaged over land, this yields 18.9 TW / (29% x 510x10 12 m 2) = 0.13 W m −2 (as in Jin et al., 2019), while globally, this yields 0.04 W m −2 when evenly distributed over the Earth's surface. This heat release is minute compared to the downwelling flux of longwave radiation of 346 W m −2 (Stephens et al., 2012) and the observed radiative forcing change at the top of the atmosphere of 2.7 W m−2 that can clearly be attributed to the increase in greenhouse gases (Forster et al., 2021). The greenhouse gas forcing
