Abstract

The unambiguous indicators of climate change caused by the industrialization of society are becoming increasingly apparent. Urgent short-term transformations in energy and transport systems around the world are needed to significantly reduce carbon emissions. The scale of the transformation, the lack of effective public response, and the inertia of changes in energy infrastructure are prompting other strategies to mitigate some of the effects of global warming. If global warming continues to rise, it could lead to serious risks of large-scale, irreversible failure in the climate system. Projections of such levels of warming are within the XXI century. As efforts to achieve ambitious emission reduction targets have so far failed, options for mitigating climate change or adapting to climate change have recently been seriously considered. Limiting global warming by 2° C above pre-industrial levels in the 21st century. Avoids dangerous human interference in the climate system. If the 2° C mark is exceeded, the effects of climate change can no longer be controlled. Currently, the increase in average global surface temperature is already about 1.0° C above pre-industrial values. It is estimated that 0.5° C is already in the climate system, especially in the oceans, and has not yet affected the planet’s surface air temperature. However, there are currently no signs of any radical containment of global warming. On the contrary, the concentration of carbon dioxide, arguably the most important anthropogenic greenhouse gas in the atmosphere, continues to rise steadily. Given this situation, it is not only the scientific community that is actively discussing artificial interventions in the climate system to limit global warming, which is known as climate geoengineering.
