Description

Civilization has affected the planet enough to initiate a new "geological" era, the Anthropocene. In it, human activity rivals nature in its impacts on global environment. Earth is not natural anymore, thanks to civilization, which is acting as a geological agent comparable to erosion or volcanic eruptions, and is already leaving a global stratigraphic imprint. It is clear that unless a global catastrophe, such as a large meteorite, occurs, mankind will remain as the greatest environmental force for millennia. Compared to the relatively stable environmental conditions of the Holocene, during which humans and society evolved, the Anthropocene would be a period of great instability. The reality of the Anthropocene is being confirmed by the current global warming, produced by anthropic emissions of greenhouse gases. The alternatives to face the climate change are those of mitigation and adaptation. The first of them mainly consists in reducing and eventually eliminating greenhouse gas emissions, which would solve the essence of the problem. The second one involves defensive actions, such as building dams against the rise in the sea level. Unfortunately, the mitigations proposed within the framework of the Copenhagen Agreement are not sufficient and climatic models predict catastrophic increases in temperature during this century. This has given support to the strengthening of a third remediation option, based on geo-engineering, which consists in the "intentional alteration of the physical and biological systems on Earth to counter the global warming". The changes that characterize the Anthropocene were produced "involuntarily" and geo-engineering would give it an overdrive, with intentional actions to control the planet's climate. Clearly, the recognition of the Anthropocene implies that humans now share responsibilities with the forces of nature in protecting the planet.
