Global warming is occurring due to the greenhouse effect trapping heat from fossil fuels, deforestation, and farming, causing average temperatures to rise since the mid-20th century. This is melting glaciers and raising sea levels while bringing more extreme weather, threatening species and agriculture. Individual actions like using low-carbon appliances, CFL bulbs, public transport, planting trees, and social change can help raise awareness and reduce the impacts of global warming.
