Which of the following best explains the effect of climate change on polar regions?

Which of the following best explains the impact of climate change on polar regions?

Which of the following best explains the impact of climate change on polar regions? … Polar regions are warming more quickly than other regions because warming decreases the coverage of high-albedo ground cover like ice and snow.

Which of the following best describes why carbon dioxide has a significant effect on global climate change?

Which of the following best describes why carbon dioxide has a significant effect on global climate change? Carbon dioxide is the largest contributor to anthropogenic greenhouse gas emissions.

Which of the following correctly explains a positive climate feedback loop found in the Arctic?

Which of the following correctly explains a positive climate feedback loop found in the Arctic? Increased precipitation increases the size of high albedo snow pack in polar regions, which leads to increased habitat for Arctic organisms such as polar bears.

Which of the following best explains how the carbon cycle plays a role in climate change?

Which of the following best explains how the carbon cycle plays a role in climate change? Changes in the carbon cycle affect the amounts of greenhouse gases, which influence climate. … Greenhouse gases are more efficient at absorbing thermal energy and reradiating it than the other atmospheric gases.

What is the effect of climate change on polar regions?

Climate change is already altering Arctic habitats. The region has warmed by nearly 10 degrees Fahrenheit since 1900, and continues to warm two to three times faster than the average for the rest of the world. Summer ice cover is shrinking, permafrost is melting and coastlines have been exposed to erosion.

What caused climate change?

The evidence is clear: the main cause of climate change is burning fossil fuels such as oil, gas, and coal. When burnt, fossil fuels release carbon dioxide into the air, causing the planet to heat up.

How does carbon dioxide affect the climate?

Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. … But increases in greenhouse gases have tipped the Earth’s energy budget out of balance, trapping additional heat and raising Earth’s average temperature.

How does carbon impact climate change?

Carbon emissions affect the planet significantly, as they are the greenhouse gas with the highest levels of emissions in the atmosphere. This, of course, causes global warming and ultimately, climate change. … This warming causes extreme weather events like tropical storms, wildfires, severe droughts and heat waves.

Which factor best explains the rise in greenhouse gases that has contributed to climate change?

Greenhouse gases in the atmosphere absorb heat radiation. Human activity has increased greenhouse gases in the atmosphere since the Industrial Revolution, leading to more heat retention and an increase in surface temperatures.

What is a climate feedback loop?

In climate change, a feedback loop is something that speeds up or slows down a warming trend. A positive feedback accelerates a temperature rise, whereas a negative feedback slows it down.

What effect do positive feedback systems have on Earth’s climate?

Forcings and feedbacks together determine how much and how fast the climate changes. The main positive feedback in global warming is the tendency of warming to increase the amount of water vapor in the atmosphere, which in turn leads to further warming.

What is a positive climate feedback?

A feedback that increases an initial warming is called a “positive feedback.” A feedback that reduces an initial warming is a “negative feedback.” Clouds. Clouds have an enormous impact on Earth’s climate, reflecting about one-third of the total amount of sunlight that hits the Earth’s atmosphere back into space.

Which of the following best describes why carbon dioxide has a significant effect on global climate change quizlet?

Which of the following best describes why carbon dioxide has a significant effect on global climate change? Carbon dioxide is the largest contributor to anthropogenic greenhouse gas emissions.

Which of the following best explains why we have seasons of different weather?

Which of the following best explains why we have seasons? Earth’s axis of rotation is at an angle to the plane of its orbit. … Which of the following best describes Earth’s climate history? Temperatures on Earth have varied throughout geologic time.

Which is the greenhouse effect?

The Short Answer:

The greenhouse effect is a process that occurs when gases in Earth’s atmosphere trap the Sun’s heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
