Climate change, primarily driven by human activities like fossil fuel combustion and deforestation, poses a global threat impacting ecosystems, biodiversity, and human societies. The Intergovernmental Panel on Climate Change (IPCC) underscores the unprecedented changes in Earth's climate due to anthropogenic actions. Greenhouse gas emissions GHG, notably carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), are major contributors, originating from fossil fuel combustion and deforestation. Deforestation releases stored carbon, hindering the Earth's CO2 absorption capacity. These human-induced activities accelerate global warming, evidenced by rising temperatures, altered weather patterns, and increased frequency of extreme events. Climate change's repercussions include melting glaciers, rising sea levels, habitat disruptions, and species endangerment. Coral reefs, crucial for marine biodiversity, face vulnerability, and ocean acidification threatens marine life with far-reaching consequences for food webs and fisheries. Changes in temperature and precipitation patterns also impact crop yields, disproportionately affecting smallholder farmers, particularly in developing nations. The interconnectedness of climate change and food security necessitates holistic strategies. Marginalized communities bear a disproportionate burden, prompting ethical concerns about climate justice. Developed nations are urged to address historical emissions and support developing countries in adapting to and mitigating climate impacts. To effectively combat climate change, a comprehensive approach combining mitigation (reducing GHG emissions) and adaptation (building resilience) is essential. Mitigation involves transitioning to renewable energy, enhancing energy efficiency, and implementing sustainable land-use practices. A collaborative effort at local, national, and international levels is vital for impactful climate action.
