The rise in greenhouse gas (GHG) emissions has significant repercussions, including global warming, climate change, and detrimental effects on biodiversity and human health.

Greenhouse gases such as carbon dioxide ($CO_2$), methane ($CH_4$), and nitrous oxide ($N_2O$) function by trapping heat from the sun within the Earth’s atmosphere, a phenomenon known as the ‘greenhouse effect.’ This effect is a natural and essential process that maintains the Earth’s temperature at a level conducive to supporting life. Nonetheless, human activities—especially the combustion of fossil fuels and deforestation—have markedly increased the concentrations of these gases in the atmosphere. This intensification of the greenhouse effect is a primary driver of global warming.

Global warming is defined as the long-term rise in the Earth’s average surface temperature. This increase is not limited to hotter summers; it also encompasses alterations in various weather patterns. For example, some regions may face more intense rainfall and flooding, while others may experience extended periods of drought. Winters may become milder, and tropical storms could strengthen in intensity. Such shifts can disrupt ecosystems, resulting in a decline in biodiversity as certain species struggle to adapt to the changing environmental conditions.

Moreover, elevated levels of GHGs directly impact human health. Warmer temperatures can worsen air quality, leading to respiratory issues such as asthma. Additionally, climate change can modify the habitats of disease-carrying insects, potentially facilitating the spread of illnesses like malaria and dengue fever. Extreme weather events—including heatwaves and floods—pose immediate threats to human safety and property.

Furthermore, the increase in global temperatures leads to the melting of polar ice, contributing to rising sea levels. This phenomenon can result in the loss of coastal habitats and even entire islands, displacing both human populations and wildlife. Additionally, it heightens the risk of coastal flooding, which can devastate communities.

In summary, the escalation of greenhouse gas emissions has extensive and far-reaching implications for our planet and its inhabitants. Addressing this intricate issue necessitates urgent attention and action.
