Global Warming: An Urgent Challenge
Global warming refers to the long-term increase in Earth’s average surface temperature due to human activities, particularly the emission of greenhouse gases (GHGs) like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O). These gases are primarily released through the burning of fossil fuels , deforestation, industrial processes, and agricultural practices. The consequences of global warming are profound and multifaceted, affecting ecosystems, weather patterns, sea levels, and human health. The Science Behind Global Warming The Earth’s atmosphere is composed of gases that trap heat from the sun, a phenomenon known as the greenhouse effect. This natural process is essential for maintaining temperatures conducive to life. However, human activities have significantly amplified this effect. According to the Intergovernmental Panel on Climate Change (IPCC), average global temperatures have risen by approximately 1.2 degrees Celsius since pre-industrial times. Projections sug...
