It’s only when we “zoom out” to the planet-wide scale that trends in surface temperature are obvious: despite a few, rare areas experiencing cooling, the vast majority of places across the globe are warming.

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.

Weather and climate occur on different scales of time and space, and depend on different aspects of Earth's environment. Weather describes atmospheric conditions at a particular time and place. Climate is the overall statistical characteristics of weather and environmental conditions, such as long-term averages and ranges of variability, for a given place and season.

Yes, human activity is putting carbon dioxide into the atmosphere faster than natural processes take it out. Rising carbon dioxide levels are strengthening Earth's greenhouse effect and causing global warming.
