How have global temperatures changed over the past century?

Over the past century, global temperatures have risen significantly, with an average increase of about 1.1 degrees Celsius (2 degrees Fahrenheit) since the late 1800s. This temperature rise is due largely to the increase in atmospheric concentrations of carbon dioxide and other greenhouse gases, which trap heat in the Earth's atmosphere and cause the planet to warm up.

According to NASA, the 10 warmest years on record have all occurred since 2005, with 2016 and 2020 being the two warmest years on record. The global temperature rise has caused changes in weather patterns, including more frequent heatwaves, more intense storms, and rising sea levels. These changes have had significant impacts on ecosystems, economies, and human health around the world.
