Global Warming, an Atmospheric Alarm
Outline
Greenhouse Gases (GHGs) And Other Man Made Chemicals Pose Human Threat
Great harm is done to the planet by manmade chemicals such as refrigerant gases. They are a major cause of global climate change. We do need these chemicals on a day by day basis, as they help us to operate essential refrigeration equipment and make our lives easier, but they represent a significant threat to human welfare. Major governments have introduced regulations limiting the use of these substances, as they present a threat to the ozone layer and contribute to global warming.
