Summary

The consequences of climate change due to the increase in CO₂ concentrations in the atmosphere are becoming increasingly clear. It is imperative to phase out the use of fossil fuels to limit the rise in temperature. Measurements show the exact course of the concentration over the last decades. But data derived from many millennia and millions of years in the past have now also been scientifically determined. On the one hand, the lecture shows that the CO₂ concentration on earth has never been as high as it is now, despite considerable fluctuations since the evolution of advanced humanoids. On the other hand, the planet has been cycling CO₂ as an essential raw material in the atmosphere, the oceans and the earth's surface for millions of years, and that this cycle can be harnessed. Renewably based synthetic fuels can help replace fossil fuels and enter such a circular economy. In addition to renewable energy and water, CO₂ is also required to produce so-called eFuels. If one benchmarks the global locations for renewable energy, it becomes clear in many places that the availability of CO₂ on an industrial scale represents a major challenge. This is not the only reason why many companies are working on extracting CO₂ directly from the atmosphere, using the so-called Direct Air Capture process (DAC).
