Summary Summary

 Weather is what we experience day-to-day

  • It can vary a lot

 Climate is a long-term average

  • It represents what is typical for a region

 Climate change is a big deal!

 Ice Cores

  • Like finding fossils in rock, ice cores give

history of Earth’s climate

 Can go back millions of years
