# Global Warming Graph and Questions

Global warming is an area of great concern for the future of our planet and our society. The graphic below, based on the data from National Aeronautics and Space Administration (NASA), shows the global annual-mean surface air temperature since the year of 1880. It is derived from the analysis of the historical data from the large network of meteorological stations.

The horizontal axis represents time and the vertical axis represents global annual-mean surface air temperature.

Examine the graphic and then answer the following questions in your post:

What were the approximate surface air temperatures in each of the following years: 1890, 1910, 1925, 1932, 1946, 1965, 1973, 1984, 1998, and 2003?
Using the values for 1890 and 2003 what would be the net global annual-mean surface air temperature change from 1890 to 2003?
In general, what does this graphic represent in terms of the global warming issue?
Based upon the graphic, what can you predict about the future global annual-mean surface temperature change in the 21st century?
Climatologists publish a number of different types of graphical aids to illustrate the global warming issue. Conduct a Web search and find a different graphic. Comment on its content and discuss what it represents. Be sure to attach a copy of the graphic or post a link to the graphic.

I will try to respond as best as I can without being able to see the graphic.

-- What were the approximate surface air temperatures in each of the following years: 1890, 1910, 1925, 1932, 1946, 1965, 1973, 1984, 1998, and 2003?

Look at the graph you have and write down the temperature indicated for each of the given years. You may want to write it in a table format, with the years in one column and temperatures in the other. For example, for 1890, look at the graph at that year (along the bottom--horizontal axis), and go up to where the dot or line is on your graph to find the temperature.
