<human>:  What are the causes and effects of global warming?
<bot>: Causes of global warming include increasing levels of greenhouse gases in the atmosphere due to burning of fossil fuels, emissions from industry and agriculture, and deforestation. Effects of global warming include rising global temperatures, melting of polar ice caps, increased sea levels, extreme weather patterns, heat waves, droughts, floods, and other extreme weather events. Additionally, global warming has been linked to changes in ecosystems, changes in agricultural productivity, and increased risk of vector borne diseases such as malaria and other health impacts.
