Global Warming
The largest indicator of climate change is global warming.
Global warming refers to the increase in the average
temperature of the atmosphere and oceans that has been
measured over the past 100 years.
The rate of increase has accelerated since the 1960s. Some regions on Earth
have experienced more warming than others and some have actually grown
cooler during this period. The warming trend is obvious by examining
temperature data as well as indirect evidence such as melting glaciers.
Independent Work
1. Read pg. 290 - 299
2. Make notes on the indicators listed on the second slide

answer the following about each indicator in your
notebook:
a. How has this indicator changed over time?
b. What effect(s) will this change have?
