Why is it important for scientists to study past climates?

Part of Hall of Planet Earth. The study of ancient climate is key to understanding how the climate system works–and how it might change in the future. Geologic records going back millions of years show that natural patterns, like shifts in Earth’s orbit, can steer dramatic changes.

Why is it important for scientists to continue in climate science?

However, scientific research can inform and guide climate-related decisions in a variety of ways. Continued research on the causes, mechanisms, and consequences of climate change will help clarify the risks that climate changes pose to human and natural systems.

What do scientists use to study past climates?

When scientists focus on climate from before the past 100-150 years, they use records from physical, chemical, and biological materials preserved within the geologic record. Organisms (such as diatoms, forams, and coral) can serve as useful climate proxies.

Why is it important for scientists to review and repeat?

Getting the same result when an experiment is repeated is called replication. … Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

What are scientists saying about climate change?

The current scientific consensus is that: Earth’s climate has warmed significantly since the late 1800s. Human activities (primarily greenhouse gas emissions) are the primary cause. Continuing emissions will increase the likelihood and severity of global effects.

Why would scientists studying climate change find the data from core samples useful?

Because trees are sensitive to local climate conditions, such as rain and temperature, they give scientists some information about that area’s local climate in the past. … Scientists can compare modern trees with local measurements of temperature and precipitation from the nearest weather station.

How do scientists use Varves to study past climate?

Varves can be counted to determine the age of the sediment, and the pollen and spores within the sediment can be extracted to see what types of vegetation were present at different times.

What are scientists who study the weather called?

It is sometimes confused with meteorology, which is the study of weather and weather forecasting. However, climatology is mainly focused on the natural and artificial forces that influence long-term weather patterns. Scientists who specialize in this field are called climatologists.

Why is it important for scientists to review and repeat the work of other scientists quizlet?

It is important for scientists to do repeated trials when doing an experiment because a conclusion must be validated. True because the results of each test should be similar. Other scientists should be able to repeat your experiment and get similar results.

Why is it important for scientists to share information with one another?

Sharing data increases data circulation and use within the scientific community by encouraging better transparency, enabling reproducibility of results, and informing the larger scientific community.

Why is it important to have repeated trials in an experiment?

Repeated trials are conducted to reduce the effect of errors and thus increase the reliability of the results of an experiment. The greater the number of repeated trials, the more confidence you can place in your data when you say that the hypothesis was or was not supported.

Why is climate change so important?

It’s important that we understand how the climate is changing, so that we can prepare for the future. Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures.

What are some possible reasons that might cause the climate to change?
