Question

which technology measures climate change?
a. weather balloons released into the upper atmosphere
b. chemical analysis of gases trapped in ice core samples
c. thermometers recording daily high and low temperatures
d. monthly air pressure measurements made by a barometer

Explanation:

To determine which technology measures climate change, we analyze each option:

• Option A: Weather balloons measure current atmospheric conditions, not long - term climate change.
• Option B: Ice core samples trap gases from past atmospheres. Chemical analysis of these gases (like CO₂) can show historical climate patterns, helping measure climate change over long periods.
• Option C: Thermometers recording daily temperatures give short - term weather data, not long - term climate change trends.
• Option D: Barometers measuring monthly air pressure are for short - term weather, not climate change.

Answer:

B. chemical analysis of gases trapped in ice core samples
