Global warming refers to the long-term increase in Earth’s average surface temperature due to the buildup of greenhouse gases in the atmosphere. It is primarily caused by human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas, which release large amounts of carbon dioxide (CO2) and other greenhouse gases into the atmosphere. These gases trap heat from the sun, preventing it from escaping back into space and leading to a gradual warming of the planet.

The greenhouse effect is a natural process that is necessary for sustaining life on Earth. However, human activities have intensified this effect by increasing the concentration of greenhouse gases in the atmosphere. This enhanced greenhouse effect is causing the Earth’s temperature to rise at an unprecedented rate, leading to various environmental and climatic changes.

The consequences of global warming are wide-ranging and include rising global temperatures, melting ice caps and glaciers, rising sea levels, more frequent and severe heatwaves, changes in precipitation patterns, more intense storms and hurricanes, shifts in ecosystems and habitats, and disruptions to agricultural practices. These changes pose significant risks to human societies, ecosystems, and economies.

Addressing global warming requires reducing greenhouse gas emissions through various means, including transitioning to renewable and cleaner sources of energy, improving energy efficiency, adopting sustainable land-use practices, promoting reforestation, and implementing international agreements and policies to limit emissions. Mitigating global warming and adapting to its impacts are crucial for preserving a sustainable and habitable planet for future generations.
