I've heard that the world is getting warmer. Is global warming a real concern?

Yes, global warming is a real concern. Scientists agree that the Earth's average temperature has been increasing over the last century due to human activities such as burning fossil fuels and deforestation. This increase in temperature can lead to more extreme weather events like hurricanes, floods, droughts, and heat waves. In addition, rising sea levels could threaten coastal cities around the world.
