What is Climate Change?

Climate change refers to long-term shifts in weather patterns and temperatures on Earth. It is primarily caused by human activities, such as burning fossil fuels, deforestation, and industrial processes, which increase harmful greenhouse gases, leading to global warming and severe environmental impacts. These greenhouse gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat in the Earth’s atmosphere, creating a “greenhouse effect” that causes the planet’s average temperature to rise.

 

The impacts of climate change are widespread and multifaceted. Rising temperatures contribute to the melting of polar ice caps and glaciers, leading to rising sea levels that threaten coastal communities and ecosystems. In addition, extreme weather events, such as hurricanes, floods, and droughts, are becoming more frequent and intense. These changes disrupt ecosystems, agriculture, and water resources, putting both human societies and wildlife at risk.

Another critical aspect of climate change is its effect on biodiversity. As temperatures rise and habitats shift, many plant and animal species are forced to adapt, migrate, or face the risk of extinction. Forests, oceans, and wetlands, which play vital roles in regulating the Earth’s climate and supporting diverse life forms, are particularly vulnerable. For instance, coral reefs, often called the “rainforests of the sea,” are suffering from bleaching events caused by warmer ocean temperatures, which can devastate marine biodiversity.

Beyond the environmental impacts, climate change also poses significant social and economic challenges. Vulnerable populations, such as those in developing nations or low-lying coastal areas, are often the hardest hit by the effects of climate change, despite contributing the least to global emissions. Economic sectors such as agriculture, fisheries, and tourism are facing disruptions, which can lead to food insecurity, displacement, and loss of livelihoods. As a result, addressing climate change is not only an environmental issue but also a matter of social justice and global equity.
