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

Yes, it is. Scientists have been warning us for decades about the effects of climate change and its potential to cause catastrophic damage to our planet. The Intergovernmental Panel on Climate Change (IPCC) has reported that the average temperature in the atmosphere has increased by 1.5°C since pre-industrial times and that this increase will continue unless we take action to reduce emissions. This could lead to rising sea levels, more extreme weather events, droughts, floods, and other negative impacts on human societies around the world.
