The fact is that it has clearly and specifically the 50s strongly heated the Earth's climate over the past centuries. This global warming not only increases the temperature of the atmosphere, but also increases sea temperature, raises sea levels and melts snow and ice (e.g. ice caps and glaciers). The causes of climate change are diverse and can be divided into man-made (greenhouse gas emissions) and natural (Earth's axis, solar activity, continental drift) causes. When it comes specifically to the man-made climate change, then we also speak of anthropogenic climate change.
