Back

Human activities, especially burning fossil fuels, increase the concentration of greenhouse gases in the atmosphere, leading to global warming.

Front

What is the impact of climate change on sea levels?

Back

Climate change causes sea levels to rise due to melting ice caps and thermal expansion of seawater.

Front

What is one effect of climate change on weather patterns?

Back

Climate change can lead to more extreme weather events, such as hurricanes, droughts, and heavy rainfall.
