What are the 2 main pieces of evidence for climate change?

What are the 2 main pieces of evidence for climate change?

Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that Earth’s climate responds to changes in greenhouse gas levels. Ancient evidence can also be found in tree rings, ocean sediments, coral reefs, and layers of sedimentary rocks.

How do scientists know about climate change?

Scientists know that recent climate change is largely caused by human activities from an understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns of climate change caused by different human and natural influences.

What are 3 ways scientists study climate change?

Scientists study Earth’s climate and the ways that it changes in a variety of different ways, using satellite, instrumental, historical, and environmental records. One challenge of using satellite and instrumental data is that their lifespans have been rather short when compared to Earth’s life.

Which indicator would tell scientists the most about future climate change?

One widely used indicator in climate science is the change in the global average temperature of the lower atmosphere.

What factors do scientists believe might have caused climate change?

Many factors, both natural and human, can cause changes in Earth’s energy balance, including:

• Variations in the sun’s energy reaching Earth.
• Changes in the reflectivity of Earth’s atmosphere and surface.
• Changes in the greenhouse effect, which affects the amount of heat retained by Earth’s atmosphere.

Why do scientists classify and compare climates?

Climate classifications help people know what types of conditions a region usually experiences through the year.

What is one tool scientists use to estimate past climates?

What is one tool scientists use to estimate past climates? Since it is not possible to go back in time to see what climates were like, scientists use imprints created during past climate, known as proxies, to interpret paleoclimate. Organisms, such as diatoms, forams, and coral serve as useful climate proxies.

What are two major factors used to identify climate Select the two correct answers?

The two most important factors in the climate of an area are temperature and precipitation.

Which weather factors are indicators of climate change?

Rising global average temperature is associated with widespread changes in weather patterns. Scientific studies indicate that extreme weather events such as heat waves and large storms are likely to become more frequent or more intense with human-induced climate change.

What are the five factors that cause climate change?

The National found out the five main culprits for this increase in greenhouse gases.

• Fossil fuels. Expand Autoplay.
• Deforestation.
• Increasing livestock farming.
• Fertilisers containing nitrogen.
• Fluorinated gases.

What are two ways Scientists classify climates?

Temperature and precipitation are used to classify different climates when using the Köppen climate classification system.
