Climate change refers to long-term shifts in temperature, precipitation, and weather patterns primarily caused by human activities, such as burning fossil fuels, deforestation, and industrial processes. These activities release greenhouse gases (GHGs), such as carbon dioxide (CO₂) and methane (CH₄), into the atmosphere, leading to global warming and its cascading effects, including rising sea levels, extreme weather events, and biodiversity loss.
Addressing climate change has become a critical focus of social impact work, engaging nonprofits, governments, businesses, and individuals in efforts to mitigate its effects and promote sustainability. Volunteerism and nonprofit involvement are essential components of these efforts, mobilizing communities to create meaningful change.
