Global warming, a phenomenon characterized by a gradual increase in Earth’s average temperature, poses significant environmental, economic, and societal challenges. This article explores the causes and effects of global warming, current scientific consensus, mitigation efforts, and the urgency of addressing climate change.

Causes of Global Warming
Global warming is primarily driven by human activities that increase greenhouse gas concentrations in the atmosphere:
Greenhouse Gases: Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases trap heat in the Earth’s atmosphere, creating a “greenhouse effect” that warms the planet.
Burning Fossil Fuels: The combustion of fossil fuels (coal, oil, and natural gas) for energy production, transportation, and industrial processes releases CO2 into the atmosphere.
Deforestation: Clearing forests for agriculture, logging, and urban development reduces the Earth’s capacity to absorb CO2 through photosynthesis, exacerbating greenhouse gas emissions.
Effects of Global Warming
Global warming has far-reaching consequences for the environment, ecosystems, and human societies:
Rising Temperatures: Higher average global temperatures lead to more frequent and intense heatwaves, impacting human health, agriculture, and water resources.
Melting Ice and Sea Level Rise: Melting ice sheets and glaciers contribute to sea level rise, threatening coastal communities, infrastructure, and biodiversity.
Extreme Weather Events: Increased frequency of hurricanes, storms, floods, and droughts can devastate communities, disrupt economies, and strain resources.
Ecosystem Disruption: Shifts in climate patterns affect ecosystems, leading to habitat loss, species extinction, and disruptions in natural cycles like migration and flowering times.
