What Is Climate Change?
Climate change occurs when extreme events like heat waves, unusually cold winters, flooding and droughts change an area's average weather conditions over time. The changing climate we are experiencing today is due in large part to higher amounts of carbon dioxide in our atmosphere caused by the use of fossil fuels.
Climate Vs. Weather
Climate is how the atmosphere behaves over time. Time could be a month, a year or more and is measured in averages. Climate is different from weather, which is the state of the atmosphere at a specific time in a specific place. Weather is what you see when you look outside right now.
Trends and Variations
When climate scientists look at data sets related to weather, they look for trends, or long-term changes in data averages. This does not mean every data point falls in line with the trend. There may be variation due to extreme events, but the average of the data points is trending in a certain direction.
