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

Geological records show that there have been a number of large variations in the 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).

What are the 2 main causes of climate change?

Of these, the two factors relevant on timescales of contemporary climate change are changes in volcanic activity and changes in solar radiation. In terms of the Earth’s energy balance, these factors primarily influence the amount of incoming energy.

What are 2 things that climate change impacts?

More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people’s livelihoods and communities. As climate change worsens, dangerous weather events are becoming more frequent or severe.

What is the main driving factor for climate change?

The main driving forces behind the fall in total GHG emissions are improvements in energy efficiency and in the energy mix. Owing to technological changes and innovation, less energy was consumed while more goods and services were produced.

What are the factors that affect climate change?

Geological records show that there have been a number of large variations in the 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).

What are the 4 main causes of climate change?

Causes for rising emissions

  • Burning coal, oil and gas produces carbon dioxide and nitrous oxide.
  • Cutting down forests (deforestation). …
  • Increasing livestock farming. …
  • Fertilisers containing nitrogen produce nitrous oxide emissions.
  • Fluorinated gases are emitted from equipment and products that use these gases.

What are the examples of climate change?

What Is Climate Change?

  • Rising sea levels.
  • Shrinking mountain glaciers.
  • Ice melting at a faster rate than usual in Greenland, Antarctica and the Arctic.
  • Changes in flower and plant blooming times.

What are 2 effects of El Nino?

Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.

What are the two reasons for rising sea levels?

What’s causing sea level to rise? Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.

What is a driving force of the climate system?

Most of Earth’s water is stored in the ocean. … Although 40 percent of Earth’s population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable.
