Answer:
The answer is "False."
Step-by-step explanation:
The sentence above is stating that you can "measure" and describe climate by "walking out the door and describing current atmospheric conditions." This is "false" because climate cannot be measured by qualitative descriptions or subjectively. Measuring it entails quantity which is objective in nature. An example of this is by using "thermometers" or "rain gauges."
Although you can describe the atmospheric condition or the climate just by walking out the door, you can never measure it.
Thus, this explains the answer.
