1. Climate change is one of the most pressing and complex issues facing humanity today. It refers to the long-term changes in the Earth’s climate system, such as temperature, precipitation, wind, and ocean currents. Climate change is caused by various natural and human factors, but the main contributor is the increase of greenhouse gases in the atmosphere, such as carbon dioxide, methane, and nitrous oxide.
5. These gases trap heat from the sun and warm up the planet, creating a greenhouse effect. The impacts of climate change are already visible and alarming in many parts of the world. Some of these impacts include melting glaciers and ice caps, rising sea levels, extreme weather events, droughts, floods, wildfires, biodiversity loss, food insecurity, water scarcity, and human health problems. Climate change also poses serious threats to social

Many individuals, groups, organizations, and governments are taking action to reduce greenhouse gas emissions, adapt to the changing conditions, and support the most vulnerable communities. Some of the actions that can be taken are using renewable
15. energy sources, improving energy efficiency, promoting sustainable transportation and agriculture, conserving natural resources, planting trees, raising awareness, and participating in global initiatives. The issue of climate change requires urgent and collective action from all sectors and levels of society. It is not only a scientific or environmental
