How does the current temperature compare to yesterday?

The choice indicating that the temperature has warmed up considerably is correct as it expresses a complete and clear comparison to yesterday's temperature by emphasizing a notable change. In the context of determining how the current temperature relates to that of the previous day, this response conveys not just a difference, but a significant improvement in temperature, suggesting a rise that is substantial enough to be noteworthy.

This construction allows for a straightforward interpretation of the temperature change, facilitating an understanding that today’s conditions are much more favorable compared to yesterday. The word "considerably" also underscores the degree of change, thus providing a more vivid description and helping the reader visualize the shift in temperature effectively.
