Your question: Which of the following are forcing agents that make the climate warmer?

What are forcing agents that make the climate warmer?

A climate forcing is an imposed, natural, or anthropogenic perturbation of the Earth’s energy balance with space (3, 4). Increasing anthropogenic greenhouse gases (GHGs) cause the largest positive (warming) forcing.

What are the agents that cause global warming?

But methane, nitrous oxide, hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs) and perfluorocarbons (PFCs) are also important agents of global warming — some of them are actually much more potent than CO2 and they stick around for hundreds to thousands of years longer.

What are the major climate forcing factors?

Climate forcing is the physical process of affecting the climate on the Earth through a number of forcing factors. … Examples of some of the most important types of forcings include: variations in solar radiation levels, volcanic eruptions, changing albedo, and changing levels of greenhouse gases in the atmosphere.

What are examples of climate forcing?

Volcanic eruptions, changes in the Sun’s radiative output, and the mostly anthropogenic changes in greenhouse gases, tropospheric aerosols, and land use are the main climate forcings for surface temperatures over the last 2,000 years.

What is climate forcing quizlet?

climate forcings. things that change global temperatures directly. -greenhouse gases, volcanoes, air pollution, land cover changes, etc. climate feedbacks. things that respond to temperature changes, but also affect temperature.

What is a forcing factor?

The main forcing factors are solar input, albedo, greenhouse gases, grading of earth’s axis, particles (aerosols), Milankovich cycluses. These forcing factors influence other factors impacting climate, mainly in feedback systems.

What are the 5 main causes of global warming?

  • Cause #5: Earth’s Own Feedback Loop.

What is causing global warming?

Global warming is an aspect of climate change, referring to the long-term rise of the planet’s temperatures. It is caused by increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.

What are the 5 causes of 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.

Which of the following is an example of external forcing?

Examples of natural external forcing include solar variability and volcanic eruptions. Examples of anthropogenic forcing are from changing concentrations of greenhouse gases and aerosols, and land cover use produced by human activities.

What is natural forcing?

The processes which cause it to change, whether natural or anthropogenic (caused by human activity), are known as forcing. Changes in solar radiation are considered to be natural; changes in greenhouse gases are considered to be anthropogenic.

What are some examples of the natural causes of climate forcing?

Another way to refer to climate forcings is to call them climate drivers. Natural climate drivers include changes in the sun’s energy output, regular changes in Earth’s orbital cycle, and large volcanic eruptions that put light-reflecting particles into the upper atmosphere.
