Understanding the factors driving short-term climate change

Climate change is like a pot of boiling water on a stove, with various factors stirring the pot and adding to the heat. Some of these factors are natural, like the flame under the pot or the occasional stirring of the water, while others are human-made, like the ingredients we add to the pot or how we control the heat.

Just as we need to understand all the components in a pot to cook a delicious meal, we need to understand the factors contributing to the climate crisis.

This article will explore the key factors contributing to short-term climate change, including natural phenomena and human activities, and how we can monitor and address their impacts to create a more sustainable future.

Illustration titled 'Short-Term Climate Change.' The illustration features a globe at the center, representing the Earth. Surrounding the globe are three graphical representations symbolizing different reasons for short-term climate change.  The first graphical symbol represents Volcanic Eruptions, indicating the impact of volcanic activities on climate through the release of ash, gases, and particles into the atmosphere.  The second graphical symbol represents Tectonic Shifts, suggesting the influence of geological movements and plate tectonics on climate patterns.  The third graphical symbol represents Solar Radiation Fluctuations, highlighting the variations in solar energy reaching the Earth's surface, which can affect climate patterns.  The illustration visually communicates the factors contributing to short-term climate change, emphasizing the role of volcanic eruptions, tectonic shifts, and solar radiation fluctuations in shaping the Earth's climate over relatively shorter time periods.

Short-term climate change is driven by several natural phenomena, including:

  • Volcanic Eruptions: Large amounts of aerosols and sulphur dioxide released into the atmosphere during volcanic eruptions can temporarily cool the Earth’s surface due to reduced solar radiation reaching the surface.
  • Solar Radiation Fluctuations: Variations in solar radiation caused by the Sun’s natural cycles can affect Earth’s temperature on short timescales.
  • Tectonic Shifts: Tectonic shifts can influence ocean currents, redistributing global heat.

Human activities have become increasingly prominent in driving short-term climate changes. The primary cause is the release of greenhouse gases due to industrialisation, deforestation, and burning fossil fuels.

Greenhouse gases trap heat in the Earth’s atmosphere, leading to a rise in average temperatures.

The United Nations identifies human-induced factors as the leading cause of the climate crisis. Therefore, addressing and understanding human-induced factors is crucial to mitigate the effects of short-term climate change.

Natural factors influencing short-term climate change

Illustration titled 'Natural Factors Influencing Short-Term Climate Change.' The illustration depicts a globe at the center, representing the Earth. Surrounding the globe are three graphical representations symbolizing different natural factors that influence short-term climate change.  The first graphical symbol represents Solar Activity, signifying the influence of variations in solar radiation and sunspot activity on climate patterns.  The second graphical symbol represents Volcanic Activity, highlighting the impact of volcanic eruptions on climate through the release of gases, ash, and aerosols into the atmosphere.  The third graphical symbol represents Ocean Currents, indicating the role of oceanic circulation patterns in redistributing heat and influencing regional climate variations.  The illustration visually communicates the natural factors that contribute to short-term climate change, emphasizing the influence of solar activity, volcanic activity, and ocean currents on shaping Earth's climate over relatively shorter time periods.

Solar activity

Solar activity is a significant natural factor that influences short-term climate change. The Sun’s energy output varies in cycles, involving changes in the intensity and distribution of sunlight reaching Earth.

This can lead to extreme weather events. As a result, changes in solar radiation caused by the Sun’s natural cycles can affect Earth’s temperature on short timescales.

Volcanic activity

Another factor contributing to short-term climate change is volcanic activity. Volcanic eruptions release large amounts of aerosols and gases into the atmosphere.

These particles can block sunlight, causing the Earth’s surface to cool temporarily. However, the cooling effect typically only lasts for a few years.

Some notable volcanic eruptions that affected climate include:

Ocean currents

Ocean currents play a significant role in regulating global climate change. They transport vast amounts of heat across the planet, affecting weather patterns and surface temperatures.

El Niño and La Niña events are significant short-term climate influences related to ocean currents. These periodic changes in the Pacific Ocean’s circulation result in altered weather patterns and can lead to extremes in temperature and precipitation in various regions worldwide.

In summary, natural factors like solar activity, volcanic activity, and ocean currents contribute to short-term climate change, affecting weather patterns, surface temperatures, and overall climate on Earth. These factors work with human-induced climate change, making it crucial to understand and monitor their impacts to devise effective strategies for addressing the global climate crisis.

Anthropogenic factors contributing to short-term climate change

Anthropogenic factors refer to human activities that significantly influence short-term climate change. These human-made factors significantly impact the Earth’s climate, altering weather patterns and surface temperatures.

The illustration portrays three distinct symbols, each representing a factor contributing to climate change:  Greenhouse gas emissions: This symbol signifies the release of gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), into the atmosphere. These gases trap heat from the sun, leading to the greenhouse effect and global warming.  Land use changes: This symbol represents alterations in land cover and land use practices. Activities like deforestation, urbanization, and agricultural expansion can impact climate by affecting the balance of carbon stored in vegetation and soils.  Industrial and transportation activities: This symbol represents human activities related to industry and transportation, such as the burning of fossil fuels for energy production and transportation purposes. These activities release greenhouse gases into the atmosphere, contributing to climate change.  The illustration aims to highlight these key factors that contribute to climate change. It emphasizes the significance of reducing greenhouse gas emissions, promoting sustainable land use practices, and transitioning to cleaner and more efficient industrial and transportation systems. By understanding and addressing these factors, we can work towards mitigating climate change and promoting a more sustainable future.

Greenhouse gas emissions

Greenhouse gases (GHGs), including carbon dioxide, methane, and nitrous oxide, trap atmospheric heat and lead to global warming. The industrial revolution notably increased the production of GHGs as human activities, such as burning fossil fuels for energy, agriculture, and deforestation, intensified.

  • Carbon dioxide (CO2). The primary source of CO2 emissions is burning fossil fuels like coal, oil, and gas for energy.
  • Methane (CH4). Agriculture, particularly livestock production, and landfills contribute to methane emissions.
  • Nitrous oxide (N2O). Fertiliser use and industrial processes release N2O into the atmosphere.

Land-Use Changes

Land-use changes, such as deforestation and urbanisation, impact climate change by altering the Earth’s surface. For example:

  • Deforestation. Removing forests increases CO2 levels in the atmosphere as trees are felled and no longer absorb carbon dioxide.
  • Urbanisation. Building cities leads to the urban heat island effect, with human-made structures absorbing and radiating more heat than natural landscapes.

Industrial and Transportation Activities

Industrial processes and transportation activities emit considerable GHGs, contributing to short-term climate change. Key industries and activities include:

  • Manufacturing. The production of cement, steel, and plastics generates substantial greenhouse gas emissions.
  • Transportation. Cars, trucks, ships, and planes emit GHGs from burning fossil fuels like petrol or diesel.

To tackle the drivers of climate change, addressing human-made factors, such as greenhouse gas emissions, land-use changes, and industrial activities, is essential. We must also recognise the severe consequences of these changes, like melting ice caps, rising sea levels, and extreme weather events affecting the world.

Study and monitoring of short-term climate change

Climate models

Climate models play a crucial role in understanding short-term climate change. These computer-generated simulations consider complex factors, enabling scientists to predict the effects of various variables on our climate.

Factors such as atmospheric carbon dioxide levels, oceanic circulation, and solar radiation are considered when creating these models.

Data from sources like satellites, tree rings, and ice cores help to enhance the accuracy of these models and provide insight into past climate patterns.

Data collection methods

Various data collection methods are employed to gather information on the drivers of climate change:

  • Satellites: Remote sensing devices orbiting Earth collect valuable data, including atmospheric carbon dioxide levels and temperature measurements. This information helps researchers to monitor climate changes over time.
  • Tree rings: Studying the growth patterns of tree rings allows scientists to understand climatic conditions in the past. Thicker rings indicate favourable conditions, while thin rings suggest periods of environmental stress.
  • Ice cores: Ice sheets in Greenland and Antarctica preserve a record of climate data stretching back hundreds of thousands of years. Researchers can determine past atmospheric compositions by analysing trapped gasses and other particles within the ice.

International organisations and research

Several international organisations help study and monitor short-term climate change, such as the Intergovernmental Panel on Climate Change (IPCC) and the National Aeronautics and Space Administration (NASA). These organisations provide scientific insight and promote international cooperation in climate change research.

Intergovernmental Panel on Climate Change (IPCC)

The IPCC is a United Nations body responsible for assessing the science related to climate change. The organisation comprises leading climate scientists worldwide, who collaborate and produce comprehensive reports on climate change impacts, mitigation strategies, and adaptation options.

National Aeronautics and Space Administration (NASA)

NASA plays a significant role in climate science by contributing to international climate research initiatives. Satellite-based measurements and data analysis help researchers monitor global temperature trends, atmospheric conditions, and other vital aspects of Earth’s climate.

NASA’s Climate Science division focuses on understanding our planet’s complex climate system to predict future changes.

By utilising these research methods and resources, experts are working to understand better and monitor short-term climate change, contributing towards informed decision-making that aims to mitigate the negative impacts of climate change on our environment and society.
