Examine the Florida panhandle indicated by the arrow on the map. If you went snorkeling in 2015, what might you have seen based on the information from this map?
Abundant bleached coral with some not recovering.
Think back to what you saw about glaciers in the US. How does the change in New Zealand glaciers compare?
