Climate change and the earth’s carbon cycle

For a long time, carbon has been referred to as the basic unit of life.

Plants and animals are both made up of the non-metallic chemical element carbon. Fats, carbohydrates, proteins, and DNA are all examples of where it may be found in the biosphere as whole.

Carbon can be found everywhere around us, even in things that aren’t alive. Carbon dioxide is the gaseous form in which it occurs in the atmosphere (CO2). Soluble in water, it’s dispersed throughout our waterways. There are fossil fuels like oil and coal that may be found in the geosphere, as well as in the soil, rocks, and rocks under our feet.

Through a variety of mechanisms, carbon flows between these “spheres” and is collectively referred to as the Global Carbon Cycle. For the survival of life on Earth, this cycle must be kept in balance.

This cycle, however, is not a fixed one. It varies, and it is subject to change, both via natural occurrences, like volcanic eruptions or the weathering of the earth’s surface, and by anthropogenic – or human-originated activities – like clear-cutting forests and the burning of fossil fuels.

According to the National Oceanic and Atmospheric Administration, the amount of atmospheric CO2 is presently “higher than at any point in the past 3.6 million years” because of the exponential rise in human population and the increasing frequency of such activities (NOAA).

This abrupt air saturation is driving climate change to the degree that campaigners are raising the alarm, calling on people, companies, and countries to reduce and terminate this global climate calamity.

Concerned “citizens,” in all its forms, are reacting to our quest for knowledge about the shifting global carbon cycle. Reforestation efforts, a reduction in emissions, and efforts to offset the carbon footprints we leave behind are all part of our efforts to combat climate change.

Carbon cycle: A comprehensive overview

Basically, the global carbon cycle may be characterized as the movement of carbon molecules across the many “spheres” and natural ecologies of the planet. Carbon has traditionally been shown as moving through:

Photosynthetic carbon dioxide removal from the atmosphere by plants or plankton for the purpose of producing organic carbon dioxide for photosynthesis.

Consumption: When plants and animals in the food chain share the majority of their organic carbon

When plants and animals exhale, they return some of the carbon they have taken in to the atmosphere back into the atmosphere.

For millions of years into the future, carbon in organic matter may decompose and be converted to fossil fuels via the process of decomposition.

Carbon cycles are more complex than a single continuous loop of simple operations. It doesn’t have a beginning or an end point that is clearly defined. Carbon enters and exits a variety of biogeochemical cycles, and it does so across a wide range of time periods as well.

Carbon is constantly moving across the planet. It is buried or subducted deep into the earth’s mantle. Geological events, such as the movement of tectonic plates, then may cause the emission of it. When magma erupts above the earth’s surface, gases may be expelled back into the atmosphere via volcanism.

Dissolution and evaporation also contribute to the movement of carbon in and out of the water cycle. In warm and cold periods, it is returned to the atmosphere by oceans and other bodies of water.

As a result of this, carbon dioxide is released into the atmosphere as a byproduct of combustion.

Lightning-caused wildfires are one example of a naturally occurring combustible phenomenon. When fossil fuels are consumed in our automobile engines or factories manufacture items for us to purchase, or when heat and electricity are generated, it is most often linked to human activity.

What is the significance of the global carbon cycle?

Considering the function carbon plays in our daily lives, such as eating, breathing, and returning to the soil, it is clear to understand how crucial it is. Carbon is more than simply a building block for life; it is the stuff that keeps it alive and well.

Life on Earth may potentially be at jeopardy if the Earth’s systems become imbalanced because of a disturbed CO2 cycle (more CO2 emissions, decreased CO2 absorption).

According to NASA’s Earth Observatory, roughly 65,500 billion metric tons of carbon are locked up in Earth’s rocks. Carbon pools in the deep ocean or ice cores hold much more, providing a record of historical carbon sequestration.

In the absence of human interference, the residual carbon in soil, oceans, and atmosphere is naturally exchanged between these three realms. In the long run, it tends to be in a state of equilibrium.

Carbon in the atmosphere has a role in regulating Earth’s temperature while it is in this condition.

Global temperatures stay generally steady when the quantity of carbon in and out of the atmosphere is almost constant. However, when there is a huge amount of carbon dioxide in the atmosphere, the Earth’s biosphere is affected and temperatures may also change substantially.

There is a cooling impact on global temperatures when there is less carbon dioxide in the atmosphere. In the form of rain, snow, or other precipitation, water vapor condenses.

Temperatures rise and more water evaporates as the concentration of carbon dioxide in the atmosphere rises. Increased humidity in the Earth’s atmosphere retains more solar energy. There is a greenhouse-like effect, which is why it’s called the Greenhouse Effect.

Plate tectonics and the compression of loose sediments into sedimentary rock are two examples of gradual carbon cycle changes in atmospheric carbon. In the span of a plant or animal’s life, other changes take place at a far faster rate.

Longer periods of higher or colder global temperatures may be expected as a result of the planet’s natural cycles, which can last for millions of years.

Despite this, new and unprecedented changes in the Earth’s carbon ratios are taking place.

How can the carbon cycle be broken?

Disruption of the global carbon cycle. Human activity has a noticeable effect on the terrestrial environment, as shown by an increasing body of scientific data.

Even though carbon cannot enter or leave the earth’s system because of the closed nature of the global carbon cycle, the Global Carbon Budget 2020 found that atmospheric CO2 concentration has risen by 48 percent since the dawn of industrialization (1750-2019).

Coal, oil, and natural gas are the most common fossil fuels used to provide on-demand heat and power. Previously “inert bundles” of carbon held in the earth are now being released into space. Worldwide fossil fuel emissions in 2019 were 61% more (36.4 gigatons) than in 1990, according to the carbon budget.

Massive shifts in land usage have taken place. For both forest products harvesting and agricultural expansion to sustain a rising human population, deforestation has expanded due to automation and increasing consumer preferences. Climate change has reduced the amount of land covered by trees and other vegetation that might otherwise serve as a mechanism of sequestering greenhouse gas emissions.

Methane and nitrous oxide, two additional greenhouse gases posing a hazard to the climate system, have proliferated as a result of industrialized agriculture.

What Is the Importance of a Disrupted Global Carbon Cycle?

The IPCC’s recently issued 6th Assessment Report (code-red) warns that disturbances to the carbon cycle are becoming the norm throughout the planet’s ecosystems. “Human-induced climatic change is already impacting numerous weather and climate extremes in every part of the planet,” it asserts emphatically.

The following are some of the negative consequences already being felt or expected by the authors of the study:

• Atmospheric carbon dioxide concentrations were greater in 2019 than they have been in at least 2 million years, according to NASA.
• Recent global surface temperatures have exceeded those of the hottest multi-century period in over 100,000 years.
• From 1971 to 2006, the average annual rate of sea level rise was 1.9 millimeters (mm), whereas from 1901 to 1970, it was 1.3 millimeters (mm).
• If we don’t drastically reduce emissions of greenhouse gases by the end of the twenty-first century, global temperature will rise by 1.5 to 2 degrees Celsius over what it was between 1850 and 1900.
• Most locations in North America, Europe, Africa, and Asia will suffer an increase in the intensity and frequency of heavy precipitation and floods as a result of global warming of 1.5 degrees Celsius.
• Agricultural and ecological droughts are more likely due to decreased soil moisture if global temperatures rise by 2 degrees Celsius.

Astonishingly large numbers. And after being bombarded with so much depressing climate data, it’s understandable that we’d start to question whether there’s anything we can do about it.

The good news is that we can all play a role in resetting the global carbon cycle right now, whether we’re individuals or company owners.

First and foremost, we must take steps to reduce our own carbon footprints in any way that technology allows us. We have the ability to:

• Using public transportation, driving an electric or hybrid vehicle, or even riding a bicycle may reduce our transportation-related carbon emissions.
• Composting, utilizing leftovers, reusing water bottles, and avoiding excessive packaging are all effective ways to reduce our impact on the environment.
• Conserve electricity and choose energy providers who are making investments in renewable energy sources like solar, wind, and hydropower to reduce our utility-related emissions.

And while we wait for the next technologies that will help us shift totally away from fossil fuels, we need to balance our individual and the global carbon footprint.

Assisting the Global Carbon Cycle by Taking a Stand

As the foundation of all life on the earth, carbon cannot be of greater importance when discussing sustainability – whether it be for plants, animals, or humans. Human-caused changes to the global carbon cycle are clearly affecting the environment.

There is a discrepancy between the amount of carbon that is stored in forests, seas, and rocks and the amount of carbon that is released into the atmosphere as a result of human activities such as deforestation and the burning of fossil fuels A increasing number of people, corporations, and countries are concerned about the rising temperatures on the world because of the extra carbon in the atmosphere.

We must all do our part to halt and finally reverse climate change. Increase your influence now by partnering with CarbonClick. It’s entirely up to you how you want to become involved.
