Question

according to this graph, what can be said about the global surface temperature trend from 1850 to 1910 as compared to the years from 1910 to 2010? figure 1. average global surface temperature based on instrumental measurements (adapted from broham et al 2006, © crown copyright 2006, data supplied by the met office). temperature rise during the twentieth century is much larger than the uncertainty range. the global surface temperature average was significantly lower during the period from 1850 to 1910. the global surface temperature average was essentially similar during both periods. the global surface temperature average was somewhat higher during the period from 1850 to 1910. the global surface temperature average was significantly higher during the period from 1850 to 1910.

Explanation:

By observing the graph, the global - surface temperature values for the years 1850 - 1910 are mostly below the 1850 - 1900 average line and are generally lower compared to the values from 1910 - 2010.

Answer:

The global surface temperature average was significantly lower during the period from 1850 to 1910.
