Climate change, also called climate variability, climate change, or climate change, is a globally occurring change in the Earth's climate.
At its core, climate change refers to the cooling or warming of the Earth's climate over a long period of time.
Not to be confused with weather - what we perceive as a short-term, current change in temperature on a daily basis.
Climate change is not a new phenomenon.
It describes the long-term changes in factors such as temperature, precipitation, and ocean currents.
These changes have been demonstrated by numerous studies and observations around the world in recent decades.
It is the long-term trends that are critical, which means that even in a long-term warming trend, there will always be outliers up or down.
"Importantly, if a year turns out to be colder than expected, this does not call into question the existence of climate change.
What are the causes of climate change?The climate is changing primarily due to the greenhouse effect: The sun's rays that hit the earth are absorbed by natural gases and clouds and some of them are reflected back to the planet. In this way, they keep it warm.
Without the natural greenhouse effect, the earth would be frozen over and our life would not be possible in this way.Today, the CO2 level is 45 percent higher than in the millennia of stability before it.
This means that the highest CO2 concentration for at least 15 million years can now be measured.
The consequence: the earth's atmosphere - the totality of gases that envelop the earth - is warming up more and more, and with it the earth - and that has fatal consequences.
What are the consequences of climate change?
Due to man-made climate change and the high concentration of greenhouse gases in the atmosphere, the surface temperature of the Earth continues to rise, already by 1.1 degrees since 1880.
As a result, not only the land on Earth is warming, but also the oceans.
More evaporation of water in turn releases more greenhouse gases.
Extreme weather conditions are on the increase, with long periods of drought or flooding in many parts of the world, destroying entire harvests and thus the livelihoods of millions of people.
Animals are also directly affected: Lack of food due to weather extremes brings many animal species to the brink of extinction.
Rising sea levels have also resulted in entire islands already being swallowed up completely, making habitats for humans and animals uninhabitable.
Worst of all, new scientific studies tend to point to a worsening and acceleration of climate change.
