Climate Change, or Climate chance??

Facts, research, conferences and opinions are not lacking today. Climate and climate change are represented each week as topics in the media. The agenda setting of climate topics sometimes determines the political present. Every human being can inform abundantly, make his own picture and do something. But first a slight limitation to the term climate.

While the weather can change every day, climate means the entire weather conditions over a long period of time in a particular area. Weather and climate strongly depend on the sunlight. The earth's surface is heated unevenly. Accordingly, the air masses are set in motion. Basically, warm air is transported from the equator towards the poles. The cool air moves in the opposite direction. The Earth's rotation deflects the winds (the so-called Coriolis effect).

These global circulations create wind systems, as well as high- and low-pressure areas. In the oceans large warm or cold streams are formed, which provide for an energy balance in the water. The climatic regions are not only determined by the atmosphere, but also by the nature of the earth's surface and the vegetation.

Today, climate is understood not only as a statistical quantity, but beyond as a system of interactions. This climate system comprises the following subsystems:

• the atmosphere with large and small-scale processes such as global wind systems or cloud formation

• the cryosphere (ice cover of the earth) with mountain glaciers and polar ice caps

• the lithosphere (rock hull) with volcanoes or raw materials

• The hydrosphere (water hull) with rivers, lakes and seas and processes such as evaporation

• the biosphere (vegetation, animal and plant species)

mankind who intervenes in all spheres, with their behaviour. In this climate system, all subsystems have an impact on the climate (in the sense of statistical quantities via atmospheric conditions and processes) and the climate in turn has an influence on the other subsystems of the climate system

"Come on" is the title of the latest report from the think tank Club of Rome. The experts have not resigned even after 50 years. What the critics overlooked, whether scientific or not, was that "limits of growth" was exactly the ruthless instrument needed to grab the world's attention.

It was an edition of only 180 pages with many graphics and charts. But that was something special. "The Limits to Growth" in 1972 set the starting point for the global environmental debate. Published by the think tank "Club of Rome" (CoR), founded in 1968, the study on the future of humanity made it almost everywhere on the bestseller lists and broadened the political horizon on the topic of sustainability - which at that time nobody called it yet. Translated into 37 languages, it sold 30 million copies.

Since then, no other scientific work had been achieved that successfully.

To achieve its goals, the Club of Rome also relies on the education of the younger generations.

To trigger people about climate change, you need an informed majority. Nothing that someone can say in a few minutes would make you change your mind, even if that celebrity is right. The people we try to reach, are those who recognize that climate change is real and does not fully understand complexity and urgency. But hardly anyone talks about the high costs of adapting to climate change. This will require many billions.

And that's the dilemma: Nobody wants to pay more taxes, nobody wants to change his life radically. Everyone hopes for a magical solution. Are we gonna wait together for what will happen and when?

In just a couple of weeks, a 22-year-old student in Berlin organized a demonstration of students in the Fridays for Future movement at the end of January 2019. The goal: to comply with the climate protection goals and the Paris Agreement. And for Germany: the shutdown of all coal-fired power plants, at the latest by the year 2030.
