a. Explain what is plotted on this graph.
b. What does the horizontal line plotted at 0°C represent?
c. When was the last time sea surface temperatures were below the 20th century average?
d. What is the approximate slope of the dashed line? (Show your work and include units.)
e. On average, a 1 °C change in temperature is enough to put corals at risk of bleaching and
death. Based on the slope of the trendline, in how many years will global temperatures be 1
C above average? Show your work and justify your answer.
5. The next question Dr. Palumbi's group asked was whether corals from cool pools could become
more heat resistant if given time to acclimate to warmer temperatures. Describe the second
experiment in a well-developed paragraph, or create a flowchart/diagram to illustrate its setup.
