Key concepts of Climate Literacy Essential Principle 4:
a. Climate is determined by the long-term pattern of temperature and precipitation averages and extremes at a location.
b. Climate is not the same thing as weather. Weather is the minute-by-minute variable condition of the atmosphere on a local scale.
c. Climate change is a significant and persistent change in an area's average climate conditions or their extremes.
d. Scientific observations indicate that global climate has changed in the past, is changing now, and will change in the future.
e. Based on evidence from tree rings, other natural records, and scientific observations made around the world, Earth's average temperature is now warmer than it has been for at least the past 1,300 years.
f. Natural processes driving Earth's long-term climate variability do not explain the rapid climate change observed in recent decades.
g. Natural processes that remove carbon dioxide from the atmosphere operate slowly when compared to the processes that are now adding it to the atmosphere
