NASA defines global warming: “Global warming is the increase in Earth’s average surface temperature due to rising levels of greenhouse gases.” So global warming is a measurable statistic. Record the temperature at many sites on Earth for a given year, add them up, and divide to get an average. Rising levels of greenhouse gases are also well measured. The famous “Keeling curve” of atmospheric CO2 begun in Hawaii in 1957 is the best example.
Climate change is more complicated. Climate change is a long-term change in the Earth’s climate and includes measures of the atmosphere, oceans, land, cryosphere (snow and ice), wind, precipitation, deforestation, wildfire, and more, as well temperature. So, climate change is a more inclusive measure of many factors changing the Earth system, which is very different from a single statistic like the rise in temperature from global warming.
Then there’s the weather. What, exactly is the weather? That word refers to what’s going on in the atmosphere at a particular time and place. It includes the air temperature, wind speed, humidity, and precipitation. Weather happens day to day, while global warming is shown by recording day-to-day temperatures over a long period of time. Climate change is a long-term process that can result in drastic changes in conditions on our planet.
To sum up: Weather refers to what’s happening in the atmosphere at a given time and place over the course of days to months.
Global warming refers to an upward trend in the average temperature over a period of years to decades.
Climate change is a long-term process that can be influenced by changes in the average temperature but includes many other factors.

Yellowstone National Park’s majestic geologic wonders and remarkable wildlife draw millions of visitors each year. But there was a time when these natural treasures were in great danger, all because after years of unrestricted hunting, one key piece of the puzzle had been eliminated—the wolf.
Now, more than a decade after scientists realized the wolves’ essential role and returned them to Yellowstone, the park’s natural balance is gradually being restored. Dorothy Hinshaw Patent's text supplemented by spectacular full-color photographs show the wolves in the natural habitat that was almost lost without them. Click here to find out more.
