"We can’t save the world by playing by the rules, because the rules have to be changed. Everything needs to change – and it has to start today.”
“I often talk to people who say, ‘No, we have to be hopeful and to inspire each other, and we can’t tell [people] too many negative things’ . . . But, no — we have to tell it like it is. Because if there are no positive things to tell, then what should we do, should we spread false hope? We can’t do that, we have to tell the truth.”
“Why should I be studying for a future that soon may be no more, when no one is doing anything to save that future? And what is the point of learning facts when the most important facts clearly mean nothing to our society?”
“Adults keep saying we owe it to the young people, to give them hope, but I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. I want you to act. I want you to act as you would in a crisis. I want you to act as if the house is on fire, because it is.”
Greta Thunberg, very young Swedish environmental activist
"If many little people do many little things in many small places, the face of our earth will change."
"Those who want something will find ways. Those who do not want something will find reasons."
The consequences of global warming are still massive: 2020 was the second warmest year worldwide after 2016, the sea ice at the North Pole shrank to the second lowest value and the sea level continues to rise. An example: There are also clear changes in Germany: The past decade (2011-2020) was the warmest on record, Germany experienced the third, far too dry year in a row and at the same time there are indications that more and more heavy rain is falling.
The climate is changing and human activity is the main reason.
It is still up to mankind to limit global warming and its consequences. However, this requires rapid and permanent changes in all areas of society - from the energy system to land use and infrastructure. The later these start, the more difficult it becomes to curb climate change and avoid irreversible changes. Man has to act - now! The facts for making smart decisions are there.
Climate change affects all regions of the world. The ice in the polar caps is melting and sea levels are rising. In some regions, extreme weather events and increased precipitation occur more frequently, while in other regions extreme heat waves and droughts are more frequent.
These effects are expected to intensify in the coming decades.
Water expands when heated. At the same time, the polar ice caps and glaciers are melting as a result of global warming.
These changes are causing sea levels to rise, causing flooding and erosion in coastal and lowland areas. Heavy rains and other extreme weather events are becoming more common. This can lead to flooding and a reduction in water quality, but in some regions it can also affect the availability of water resources.
Heat waves, forest fires and droughts are more common in southern and central Europe.
Drought is spreading across the Mediterranean, making the region even more vulnerable to droughts and forest fires.
In Northern Europe, on the other hand, the climate is becoming significantly more humid and winter floods could become the norm.
The urban areas, where four in five Europeans now live, suffer from heat waves, floods or sea level rise, but are often barely able to adapt to climate change.
Many poor developing countries are among the countries hardest hit by climate change. The people living there are often heavily dependent on their natural environment and have the least of the resources they need to cope with the climatic changes.
Climate change is already affecting health:
Heat-related deaths increased in some regions and cold-related deaths decreased in others.
Changes are already being observed in the spread of certain water-based diseases and disease carriers.
The extent to which climate change will take depends very much on our actions. So far, the global temperature has risen by around one degree compared to the pre-industrial level. For comparison: At the transition from the last Ice Age, the earth warmed by around 5 ° C and took 5,000 years to do this. Our behavior has increased one degree in just 100 years. This is noticeable: 18 of the 19 hottest years since the weather records began were since 2001 (as of 2019). By the end of the century, the temperature could rise by 4.8 ° C compared to pre-industrial levels. The higher the temperature rises, the greater the risks associated with it.
Climate change and climate extremes are already among the most important factors in malnutrition and the occurrence of hunger crises. In 2017, 59 million people in 24 countries in Africa were affected by malnutrition and the loss of food security as a result of climate events. Across the continent, 70 to 80 percent of the population is dependent on arable farming or livestock farming. Both forms of agriculture are highly climate-sensitive.
Around a quarter of the CO2 emitted is absorbed by the oceans, thereby changing the pH value. So far, this has already reduced the pH of the oceans by 0.1. If the acidity of the oceans changes, this affects the ability of crustaceans to form shells or corals to form reefs (cf. WMO, 2019, State of the Climate 2018). The sea is acidifying, the conditions are becoming more hostile to life.
In this way we will soon no longer have a future !!!
