Global warming is caused by the greenhouse effect where greenhouse gases trap heat in the atmosphere. The greenhouse effect contributes to climate change by speeding up the natural process. The primary causes of global warming are carbon dioxide emissions from fossil fuels and methane released from various sources. If global warming continues unchecked, there will be consequences like rising sea levels, stronger storms, and changing ecosystems. Global warming is also economically impacting industries like farming through changing weather patterns. Individual actions like using energy efficient appliances and driving less can help fight global warming.
