I've been hearing about the global warming issue. Is it true that global warming is caused by humans?

Yes, it’s true that human activities are contributing to global warming. Humans are releasing large amounts of carbon dioxide and other greenhouse gases into the atmosphere, which traps heat from the sun and causes temperatures to rise. This increase in temperature has had a wide range of effects on the Earth's environment, including rising sea levels, changes in precipitation patterns, melting glaciers and ice sheets, and an increase in extreme weather events.
