Why are mathematical models important to the study of climate change?

You may be aware of the current weather conditions. The variations we see and experience outside from day to day are referred to as weather.

One day it may rain, and the next it may be bright. It becomes frigid at times. It may get rather heated at times. The weather varies from location to area as well. 

In one location, people may be wearing shorts and playing outside. People far away may be shovelling snow at the same moment.

Climate refers to a location’s typical weather. Seasonal climates can be rather diverse. In the summer, a location may be primarily warm and dry. In the winter, the same location may be cold and rainy. Climates differ depending on where you are.

A shift in a location’s typical weather is referred to as climate change. This might be due to a shift in the amount of rain that a location receives on a yearly basis. 

It might also be a variation in a location’s normal temperature over the course of a month or season.

Climate change is a term that refers to changes in the Earth’s climate. This might be due to a shift in the Earth’s normal temperature. It might also be a shift in where rain and snow fall on Earth.

In just a few hours, the weather may shift drastically. Climate change can take hundreds of years or perhaps millions of years.

In this article, we discuss the importance of using mathematical models in climate change studies. 

Why are mathematical models important to the study of climate change?

A mathematical model is a linguistic and mathematical concepts-based description of a system. Mathematical modelling is the process of creating a mathematical model.

Mathematical models are utilised in natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical systems (such as the social sciences) (such as economics, psychology, sociology, political science). 

A big element of operations research involves the use of mathematical models to address issues in commercial or military operations.

Advantages of mathematical modelling

There are many benefits a mathematical model provides when it comes to studying real life problems. Some of these are:

  • Models have the ability to correctly depict reality. A model can be incredibly accurate if it is correctly formulated. A valid model is one that accurately and accurately portrays the problem or system being studied.
  • Models can aid in the formulation of problems by decision-makers. A decision maker can determine the essential aspects or contributions to temperatures and other parameters, such as mean sea level, extreme events, land use change, for example.
  • Models may provide us with insight and data. For example, we can use the climate model to observe how changes in carbon dioxide levels affect surface temperature.

    Sensitivity analysis, as stated in the preceding section, is the process of examining the effects of modifications in a model, such as a profit model.
  • Models can help you save time and money while making decisions and addressing problems. Analysing a model generally involves less time, effort, and money.

    A profit model may be used to assess the impact of a different chemical constituent or a physical event on various parameters of the globe or a region.

    Using models is usually faster and less expensive than testing a marketing campaign in a real company setting and watching the outcomes.
  • A model may be the only option to quickly tackle some huge or complicated issues. For example, a huge industry may create hundreds of different types of emissions in the form of gases, liquid droplets, or solid particulate matter.

    Given its technological limits, the corporation may aim to make the most money feasible.

    In these conditions, a mathematical model may be the only method to predict the company’s maximum revenues it can generate without significantly contributing to the regional pollution levels.

What causes climate change?

The climate of the Earth is always changing. The Earth’s climate has been warmer in the past than it is currently. There have been colder days in the past. Thousands or millions of years can pass during these periods.

Earth scientists see that the planet’s climate is warming. In the previous 100 years, the Earth’s temperature has risen by around one degree Fahrenheit. 

This may not appear to be a significant amount of money. Small variations in the Earth’s temperature, on the other hand, can have significant consequences.

Some impacts have already begun to manifest. Some snow and ice have melted as the Earth’s temperature has warmed. Oceans have also risen as a result of global warming. It also shifts the time of certain plants’ growth.

However, since the onset of the Industrial Revolution, climate change is predominantly driven by anthropogenic (i.e., human-based) activities.

Activities such as burning of fossil fuels, deforestation, urbanisation, and so on contribute heavily to the emission of greenhouse gases in the Earth’s atmosphere.

Amongst these gases, the most notorious is carbon dioxide. Ever since the industrial revolution, its concentration in the atmosphere has gone up from 280ppm (parts per million) to 420ppm.

Due to the greenhouse effect, the Earth’s temperature has been rising steadily, a phenomenon known as “Global Warming”.

Due to this, rapid melting of glaciers and ice sheets, warming and subsequent acidification of oceans, and many such phenomena have taken place which in turn have adversely affected biodiversity.

Can an individual do something about global warming?

Yes. While large-scale government action at the national level is required to win the battle, we also need the aid of individuals who are ready to speak up, hold government and business leaders accountable, and modify their everyday behaviours.

Do you want to know how you can help in the battle against global warming? Take a few simple ways to reduce your personal carbon footprint: Make energy conservation a part of your everyday routine and purchase decisions. 

Look for the government’s logo on new appliances like refrigerators, washers, and dryers; they satisfy a higher level for energy efficiency than the minimal federal requirements.

When shopping for a car, aim for one that gets the best gas mileage and emits the fewest pollutants. When possible, you may also limit your emissions by utilising public transit or carpooling.

While the new federal and state regulations are a start in the right direction, there is still much more to be done. 

Make your voice heard in favour of climate-friendly and climate-change readiness measures.

Furthermore, remind your legislators that a just transition from filthy fossil fuels to clean energy should be a key priority, as it is critical to the development of healthy, secure communities.

You also don’t have to do it alone. Climate action can build community, be led by those on the front lines of its effects, and create a future that is equitable and just for all, as demonstrated by movements around the country.

Conclusion

Climate change is a term that refers to changes in the Earth’s climate. This might be due to a shift in the Earth’s normal temperature. It might also be a shift in where rain and snow fall on Earth.

Climate change is predominantly driven by anthropogenic (i.e., human-based) activities.

Activities such as burning of fossil fuels, deforestation, urbanisation, and so on contribute heavily to the emission of greenhouse gases in the Earth’s atmosphere. Climate change not only affects humans, but severely affects biodiversity. 

In order to study climate change in an intricate manner, it is important to use mathematical models. These models help to understand the relationships as well as predict the future trends based upon the observations and data from the past.

FAQs

Is global warming already happening?

Yes. Based on scientific evidence and observed changes in modern day climate, global warming has already begun. Month after month, year after year, record high temperatures are set both locally and worldwide.

Temperatures, on the other hand, are only one of several indications of global warming. Warmer temperatures bring a slew of changes, all of which hint to a planet in flux.

What are some examples of climate change?

The following are the example for observed climate change:

  • Since the pre-industrial period, the global average surface temperature has risen by around 1°C.
  • In the second part of the twentieth century, there was a decrease in snow cover and sea ice extent, as well as the retreat of mountain glaciers.
  • Global average sea level rise and ocean water temperature rise.
  • Average precipitation is expected to rise across the Northern Hemisphere’s middle and high latitudes, as well as over tropical land regions.
  • Extreme precipitation events are becoming more frequent and intense in various parts of the world.

The following are the example for physiological and ecological changes that are linked to climate change:

  • Permafrost thawing
  • In the middle and high latitudes, the growth season is lengthening.
  • Plant and animal ranges are shifting poleward and higher.
  • Some plant and animal species are on the decline.
  • Trees begin to bloom earlier.
  • Insects are emerging earlier.
  • Birds deposit eggs earlier.

What are solutions to climate change?

To avoid the worst effects of climate change, the Intergovernmental Panel on Climate Change (IPCC) recommends that carbon emissions be reduced to the point where global warming is limited to no more than 1.5 degrees Celsius (3 degrees Fahrenheit).

To do so, we must commit as a planet to achieving net zero carbon emissions by 2050. This is no minor task, and achieving the goal will need a combination of solutions.

All sectors of our economy will need to move away from carbon-emitting fossil fuels, expand our use of sustainable energy sources like wind and solar, harness the power of nature to trap carbon, and implement carbon-capture-and-storage technology.

This transition will happen much faster and more cost-effectively if governments enact an economy-wide price on carbon.

How is climate change affecting people?

Climate change is hurting people all around the world, from straining agricultural systems to making places less livable. 

You may have observed how weather patterns are altering around you, or how storms are becoming more common and violent in the spring. 

Perhaps you’re dealing with more severe flooding or wildfires in your area. Rising sea levels are causing streets to flood during high tides in several regions, resulting in “sunny day flooding.” 

Because the sea level has risen to the point where their original position is no longer livable, several whole coastal settlements in Alaska are being relocated.

Climate change also heightens the risk of human-caused conflict due to a lack of resources such as food and water, which becomes less reliable as growing seasons shift and seasons become less predictable.
