There are many policies implemented so far worldwide, but as the Union Square climate clock in the heart of Manhattan highlights, a greater effort is needed. The work of Gan Golan and Andrew Boyd shows, with its countdown, how much time we have left to limit carbon emissions before we reach a point of no return.

Controlled air recirculation is widely used in mines for minimizing the energy consumption of fans, winter air heating costs, as well as dedusting and dehumidification of mine air. In most cases today, controlled air recirculation is used for potash mines. However, it can be applied to metal and non-metal mines if its safety and energy-efficiency are substantiated. For potash mines, a scientific substantiation for the applicability of the recirculation is also required in specific cases. The paper presents the stu...
