Construct a scatter plot, with years on the x-axis and sea surface temperature for a particular month on the y-axis. > //divide the work between the class up so that every month is covered.// > > b. Is there a difference between months or do they all show the same trend? Discuss
 * 1) copy the data into excel.
 * 1) Determine the mean sea surface temperature for each year.
 * 1) Construct a scatter plot with a trend line of mean annual sea surface temp. vs. year using excel.
 * 1) Discuss whether this provides evidence of global warming.
 * 1) Now look at specific months:
