(Q013) Which of the following is an accurate description of a method used to study short-term climate change? The color of a tree ring indicates the rate of growth in a given year. Pollen is useful for studying modern-day climate but cannot be used to study ancient climate because pollen is not preserved in sediment. The oxygen-isotope ratios of glacial ice record changes in global temperature for the past 800,000 years. All of the possible answers are correct.

The oxygen-isotope ratios of glacial ice record changes in global temperature for the past 800,000 years. All of the possible answers are correct.
Solution
The correct answer is: "The oxygen-isotope ratios of glacial ice record changes in global temperature for the past 800,000 years."
This method is accurate for studying short-term climate change. The oxygen-isotope ratios in glacial ice can provide a record of past temperatures, and thus climate changes, over a long period of time.
The color of a tree ring does indicate the rate of growth in a given year, but this is more commonly used to study local environmental conditions rather than global climate change.
Pollen can indeed be used to study ancient climate, as it is often preserved in sediment. However, it is more commonly used to study changes in plant communities rather than climate change.

Earth-orbiting satellites, remote meteorological stations, and ocean buoys are used to monitor present day weather and climate, but data from natural sources like ice cores, tree rings, corals, and ocean and lake sediments have enabled scientists to extend the earth’s climatic records back to some millions of years. These records provide a comprehensive look at the long-term changes in the earth’s atmosphere, oceans, land surface, and cryosphere. Scientists then feed this data into sophisticated climate models that predict future climate trends.Write down the most suitable topic:
