Topic: Climate literacy

Some say that climate is what you expect and weather is what you get. More formally, climate is the long-term average of temperature, precipitation, and other weather variables at a given location. Every 30 years, climate scientists calculate new averages. The normal high and low temperatures reported on your local weather forecast come from these 30-year averages. Although climate describes conditions in the atmosphere (hot/cold, wet/dry), these conditions are influenced by the ocean, land, sun, and atmospheric chemistry. NOAA monitors these factors to understand and predict changes to local or global climate.

Though we often think about human-induced climate change as something that will happen in the future, it is an ongoing process. Ecosystems and communities in the United States and around the world are being impacted today. 

Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
