What is the main driver for our climate system quizlet?

What drives the climate system?

The climate system is powered by radiation from the sun, of which approximately 49% is absorbed by the Earth’s surface, and 20% is absorbed by the atmosphere (Kiehl & Trenberth 1997). This energy warms the planet, but the warming also causes Earth to start radiating energy back into space.

What are the drivers of Earth’s climate system?

The sun provides the primary source of energy driving Earth’s climate system. The sun’s energy, called solar radiation, isn’t equally distributed across the globe because of Earth’s spherical shape. This “unequal helping” of solar radiation across our planet is effectively what causes weather and climate.

What is the primary driver of Earth’s climate?

Solar radiation is a primary driver of climate. Earth system science is the study of how scientific data stemming from various fields of research, such as the atmosphere, oceans, land ice and others, fit together to form the current picture of our planet as a whole, including its changing climate.

What is the ultimate driver of the climate system?

Energy from the Sun is the ultimate driver of climate on Earth. The solar energy received by Earth depends on how much the Sun emits and the distance between Earth and the Sun. Part of this sunlight is reflected directly back to space by the atmosphere, clouds, and land, ice and water surfaces.

What are the three main processes that control Earth’s climate?

> The Earth’s climate is influenced by many factors, including solar radiation, wind, and ocean currents. Researchers try to integrate all of these influencing variables into their models. Many of the processes involved are now well understood.

What are the 5 major parts of the climate system?

Its components The climate system, as defined in this Report, is an interactive system consisting of five major components: the atmosphere, the hydrosphere, the cryosphere, the land surface and the biosphere, forced or influenced by various external forcing mechanisms, the most important of which is the Sun (see Figure …

What are the 2 main driving factors for changes in Earth’s climate?

These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth’s orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.

What are the drivers and indicators of climate change?

The Earth’s climate is warming, mostly due to human activities such as changes in land cover and emissions of certain pollutants. Greenhouse gases are the major human-influenced drivers of climate change. These gases warm the Earth’s surface by trapping heat in the atmosphere.

What is a climate impact driver?

Human-caused, or anthropogenic climate drivers include emissions of heat-trapping gases (also known as greenhouse gases) and changes in land use that make land reflect more or less sunlight energy. Since 1750, human-caused climate drivers have been increasing, and their effect dominates all natural climate drivers.

What are the major drivers of human carbon dioxide emissions in the world?

Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.
