Can global climate change affect the life of the modern planet, or could it only occur in geologically distant eras?

Global climate change is currently taking place, but very slowly. In particular, due to the high gas pollution of the atmosphere by emissions from cars, chemical, nuclear and other enterprises, there is a gradual increase in temperature throughout the planet. An increase in temperatures in the region of the North and South poles leads to an increase in the temperature of the water in the seas, and glaciers are melting. With the melting of glaciers on a global scale, there will be a rise in the level of seas and rivers throughout the planet, which will lead to the flooding of continental territories, which will make them unsuitable for habitation of land plants and animals.
