globalwarming.png
This image displays a line graph with a white background and light gray grid lines. At the top center, there is a legend consisting of a small blue square followed by the text "global warming," indicating that the blue line represents data for global warming.

The horizontal x-axis at the bottom represents time in years. It is marked at 20-year intervals with the following labels from left to right: 1800, 1820, 1840, 1860, 1880, 1900, 1920, 1940, 1960, 1980, and 2000.

The vertical y-axis on the left represents a percentage value with very small increments. The labels start at the bottom with "0.0000000%" and increase by 0.000020% for each grid line up to the top label, which is "0.0002000%".

The data is plotted as a solid blue line. From the year 1800 until approximately 1900, the blue line remains completely flat along the bottom axis at 0.0000000%. Between roughly 1900 and 1920, there is a very small, brief spike where the line rises slightly above zero before returning to the baseline. From approximately 1920 until just after 1980, the line remains flat again at 0.0000000%. Starting around 1980, the blue line begins a sharp, exponential upward curve. By the year 2000, the line has risen steeply to reach near the top of the graph, ending just below the 0.0002000% mark.
