Our planet is getting warmer. Every year, NASA and NOAA calculate the average surface temperature around the globe. These annual temperature data make up the global temperature record – and it’s how scientists know that the planet is warming. Red spirals in this visualization indicate years with warmer-than-average temperatures. The visualization “turns red” after 1975, showing that most of Earth’s warming has occurred in the last several decades. Overall, the average global temperature on Earth

Climate change is happening. Here's a look at global temperature from 1861 to 2020. Note how temperature varies and then rapidly accelerates over the last 30 years 📈 In fact the 5 hottest years across the globe have been the last 5 years. | Met Office
