Climate Change
Climate change refers to long-term changes in temperatures and weather patterns. These changes may be natural, such as through variations in the solar cycle. Human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil, and gas.
Burning fossil fuels generates greenhouse gas emissions like a blanket wrapped around the Earth, trapping the sun’s heat and raising temperatures. Climate change puts people at risk of food and water scarcity, increased flooding, extreme heat, disease, and economic loss.
