Global warming is the increase of Earth's average surface temperature due to greenhouse gases that collect in the atmosphere. Greenhouse gases such as carbon dioxide (CO2) and methane (CH4) absorb heat that would otherwise escape from the Earth. No science-fiction, scientifically proved facts.
Global warming results in more extreme weather conditions. More natural disasters, like floods and earthquakes, are taking place. Temperatures are getting more extreme. Rain and snowfall are increasing across the globe, on average.
Loss of Biodiversity
Increases in atmospheric CO2, temperature and precipitation, like rain, have significant effects on the growth of organisms. These can be harmful beyond their physiological limits. They affect their distribution and their life cycle directly. Indirect effects are caused by interaction with other species.
Sea Level Rise
Ice sheets and glaciers are melting by the increasing surface temperature. The water from melting ice results in a rising sea level. Within the foreseeable future, the sea level could rise by 4 to 6 metres or more.
Temperature rise can affect human health and diseases they are exposed to. With increasing rainfall, temperature, water-borne diseases, like malaria, are likely to spread. Heat waves can also cause damage to young and old people.
