Causes of climate change include burning fossil fuels (petroleum, coal, natural gas), deforestation, methane released in atmosphere, and human consumption.

Consequences include sea level rise, species endangerment, spread of tropical diseases, and possible agricultural loss.

Solutions and trade-offs include:

• Alternative energy sources (can be costly)
• Irrigation (can cause water shortage)
• Reforestation (costly in resources and land)
• Levees and sea walls (costly and alters habitats)
