Carbon Emissions - Why Are Co2 Emissions Bad

What do people really mean when they talk about reducing global warming? What are greenhouse gases and why do they threaten the environment? There are so many different terms and opinions out there that it can be difficult to understand everything surrounding greenhouse gases. Read on to get the answers to the most common questions and understand fully why greenhouse gases are a problem.

What are greenhouse gases?

Technically speaking any gas that absorbs and emits radiation is a "greenhouse gas." Water vapor, methane, ozone, nitrous oxide, and carbon dioxide are all classified as greenhouse gases. However, carbon dioxide is the most prevalent of all greenhouse gases, which is one of the reasons it comes up so frequently when discussing climate change issues. According to a study conducted by the EPA in 2019, carbon dioxide made up 81% of all greenhouse gases.

Carbon dioxide exists naturally as a trace gas in the Earth’s atmosphere. Although CO2 concentrations in the air fluctuate naturally with the seasons, anthropogenic factors like fossil fuel combustion and widespread deforestation have increased the quantity of carbon dioxide present in the atmosphere, with negative climatic and environmental effects.

Since the time of the Industrial Revolution, atmospheric CO2 concentrations have increased by a worrisome 43%. On a global scale, this is a significant change. Human activities emit 29 billion tons of carbon dioxide each year, and most of this derives from the burning of fossil fuels for energy.

Carbon dioxide is a problem because it acts as a "greenhouse gas." Due to its molecular structure, CO2 absorbs and emits infrared radiation, warming the Earth’s surface and the lower levels of the atmosphere. This leads to a positive feedback cycle: as temperatures increase due to atmospheric CO2 levels, CO2 levels increase due to the warming temperatures.

Why are carbon emissions a problem?

Over the last 150 years, human activity has brought the amount of carbon dioxide in our atmosphere to levels that have not been seen for hundreds of thousands of years. The magnitude of this impact is immense. Humans today have so much impact on a global scale that most geologists, ecologists, and natural historians maintain that we have entered an entirely new geological epoch, known as the Anthropocene.

Ongoing scientific research has made it increasingly clear that it is in humanity's best interest, as a species, to move away from dependence on fossil fuel combustion.

How do greenhouse gases affect the Earth?

Each gas's effect on the planet depends on three primary factors:

  1. The concentration of the gas Scientists measure greenhouse gas concentrations in parts per million, parts per billion, and even parts per trillion. One part per million is the equivalent of one drop of water mixed into around 13 gallons of liquid, which amounts to the fuel tank of a medium-sized car.
  2. How long the gas stays in the atmosphere Any of the gases mentioned above may remain in the atmosphere for a few years to tens of thousands of years. These gases all linger in the atmosphere long enough to become well mixed, and the amount measured in the atmosphere is about the same globally, regardless of where the emissions came from.
  3. How badly they affect the atmosphere Certain gases are more responsible for global warming than others. Every greenhouse gas has a corresponding Global Warming Potential (GWP) to reflect how long it stays in the air and how aggressively it absorbs energy. Gases with a higher GWP contribute the most to global warming as they absorb more energy per pound than those with a smaller GWP.

Why is the increase of greenhouse gases a big issue?

Greenhouse gases pose severe environmental and health issues. They cause climate change by trapping heat, which in turn affects various species in already arid climates. The climate change caused by greenhouse gas emissions also contributes to extreme weather, wildfires, droughts and food supply disruptions. If our planet continues to release greenhouse gases at the current rate, the typical weather patterns will change, and some animal species will likely disappear. Greenhouse gases also contribute to air pollution and smog, which can cause respiratory and pulmonary diseases.

What are 3 causes of climate change?

Here are three causes of climate change:

  1. A huge proponent of climate change is the burning of fossil fuels like coal, oil and gas. These gases contain carbon dioxide that has been stored in the ground for millennia, and when we extract these fuels from the land to burn them, we release that carbon dioxide into the air.
  2. Agriculture is another proponent of greenhouse gas emissions. The planting of crops and rearing of animals releases several types of greenhouse gases into the air. For example, cattle herds produce methane when they pass gas, and this methane is 30 times more powerful than carbon dioxide. The crop fertilizers used by farmers contain nitrous oxide that is nearly 300 times more potent than carbon dioxide. That’s why cutting down on red meat and dairy products is an important planet-friendly lifestyle choice – it drives down demand for this product.
  3. Deforestation occurs when trees are cut down to make way for agriculture or grazing or chopping down trees to use the timber for fuel, manufacturing and construction. Forests contain trees that naturally remove and store carbon dioxide from our atmosphere. Cutting these trees down results in a quicker build-up of carbon dioxide as there aren’t any trees to absorb it. Trees also release the carbon they were storing when we burn them, so the damage is even more severe.

Many situations often cause deforestation, but the most damaging process is beef production. The damage done by beef production is more than double the damage done by soy, palm oil, and wood production combined.

What caused global warming?

Global warming occurs when carbon dioxide and other pollutants accumulate in the atmosphere. These air pollutants absorb sunlight and radiation that have bounced off the earth’s surface. This radiation would normally escape into space, but these pollutants can last for centuries in the atmosphere, trapping the heat and causing the nearby planet to heat up. These pollutants trap heat and are referred to as greenhouse gases. Their negative impact on the planet is known as the greenhouse effect.

What is the largest contributor to greenhouse gases?

Here in the US (and in most other areas of the world), the biggest contributor is the burning of fossil fuels. Everytime you use gas in your car, natural gas in the kitchen, or flick a light, you’re likely using a fossil fuel. If you look around you, it’s likely most of those things were made with tools or processes that used fossil fuels, too. Every time we burn a fossil fuel it releases more harmful gases that contribute to the greenhouse effect.

If you want to contribute less to this issue, there are two important actions you can take. First, switch your home’s electricity supply to a 100% green clean electricity plan. Inspire helps its members do just that in many states around the country. If you want to see if we can help you, click here.

The other option you have is to use eco-friendly transport. While switching to an electric vehicle is the best option, it’s also the most costly and not always practical. If your lifestyle allows for it, consider switching to a vehicle with a high MPG (miles per gallon) will help you save money and get further on less fuel.

How serious is global warming?

Each year, we discover more about the consequences of global warming through evidence of its worrisome impact on the planet and its inhabitants. Climate change causes heatwaves, fires, droughts, and floods, and as they become more frequent and dangerous, people and animals suffer.

Why are carbon emissions a global problem? If we don’t reduce our global emissions, climate change could result in the deaths of over 250,000 people globally and annually. These devastating effects will likely also force 100 million people into extreme poverty by 2030. In countries that already have high levels of suffering and poverty, this could have disastrous effects that we cannot afford to risk.

So, given the concerning outcomes of carbon emissions worldwide, carbon emissions are certainly not exclusive to certain countries.

When did greenhouse gases become a problem?

In the 1980s, the world’s annual mean temperature curve began to rise, increasing so steeply that global warming became better known as a theory. Environmental NGOs (Non-Governmental Organizations) began advocating global environmental protection to curb further global warming. Global warming soon became a hot news topic that was repeated all over the world. It may be surprising that this information became public knowledge so late, but before then, the idea of global warming was simply a theory. Shockingly, it wasn’t until June 23, 1988, that climate change officially became a national issue.

How can we solve global warming?

Pretty much every sector of the global economy, from agriculture and manufacturing to power production and transportation, contributes to releasing greenhouse gases. To avoid the worst effects of large-scale climate change, all of these sectors must shift away from fossil fuels. The changes are vital for the biggest emitters, with twenty countries causing around three-quarters of global greenhouse gas emissions, with the US, China and India in the top three.

We already have the technology needed to reduce greenhouse gas emissions. These changes would entail boosting energy efficiency in warehouses and industrial factories, swapping fossil fuels for renewable sources and discouraging carbon emissions by charging companies for releasing them.

How can humans reduce the level of greenhouse gases?

As we explored above, the main culprits of greenhouse gas emissions are large corporations, but we individuals are responsible too. Reducing our global carbon footprint requires everyone to make a small effort, but thankfully, it’s relatively easy to do your bit to solve global warming.

Here are some ways you can do it at home:

  • Switch to an energy-efficient utility provider. You’d be surprised how many utility companies still rely on fossil fuels for their customers’ energy needs, but you don’t have to contribute. Click here to find out how Inspire can help you switch to 100% clean energy.
  • Drive less and walk or cycle where you can: this will reduce your personal contribution to air pollution.
  • Eat low on the food chain, or even follow a plant-based diet. Reducing your dependence on animal products helps drive down the country’s demand for methane-producing produce.
  • Cook and buy in bulk to save money and energy.
  • Wash your clothes in cooler water, so your washing machine doesn’t have to heat the water.
  • Replace your light bulbs with energy-saving bulbs once they run out.
  • Reduce your consumption of single-use plastic. Instead of opting for a plastic take-out cup from your favorite cafe, bring a reusable cup. Invest in a tote bag to avoid plastic grocery bags and a flask to avoid buying plastic water bottles.
  • Replace regular household items with eco-friendly, plastic-free options, or even make your own!
  • Eat local, in-season food and support stores that buy produce with low air miles.
