What can the rising global temperatures lead to?

Among other things, the rising global temperatures can lead to the melting of polar ice caps, ozone depletion (making the ozone hole larger), animal species being eradicated and an increase in the occurrence of natural disasters.

The greenhouse effect

Earth is surrounded by an atmosphere that consists of several different gases. Some of these gases, including water vapor, carbon dioxide, methane and nitrous oxide, are so-called greenhouse gases.

Greenhouse gases have properties that prevent heat radiation from leaving our planet. This phenomenon is called the greenhouse effect and is necessary for all life on Earth. Without this protective atmosphere of gases, Earth would be about 30 degrees Celsius colder than it is today.

However, when the level of atmospheric greenhouse gases increases (for example, through carbon dioxide emissions), the greenhouse effect is strengthened which causes global temperatures to rise.
