Climate change refers to long-term shifts in temperatures and weather patterns, mainly caused by human activities—especially the burning of fossil fuels like coal, oil, and gas. This increases greenhouse gases (like CO₂) in the atmosphere, trapping heat and warming the planet.
Some key effects include:
Rising temperatures and more frequent heatwaves
Melting glaciers and rising sea levels
More intense storms, droughts, and wildfires
Shifts in ecosystems and threats to biodiversity
Impacts on agriculture and food security
