Considering some locations experience temperature swings of 30°F or more in a single day, warming of 1.8°F (1°C) might seem small, but Earth's annual temperatures are very stable when climate isn't changing.
Our global historical temperature records undergo rigorous quality control and independent peer review. Plus, the proof Earth is warming is practically everywhere you look.
Differences in exposure to sunlight, cloud cover, atmospheric circulation patterns, and other factors influence whether and how much a location is warming or cooling.
