Is Climate Change Real & Human-Caused?

The ISCFC is all about reducing our individual and collective contributions to climate change.

But is climate change really happening? Is it mostly caused by human activity, including our production of carbon dioxide and other greenhouse gases?

In the United States and elsewhere, there are people who are not convinced by the science. But the great thing about science is that we use evidence to evaluate scientific questions. So what is the evidence related to climate change?

Are you or are you not convinced by the majority of climate scientists who say that climate change is real and largely human caused? Why are you convinced/not convinced? What evidence might change your mind one way or the other?

climate change caused by humans

yes, I think humans are the cause of climate change. Before the industrial revolution, the amount of carbon dioxide in the atmosphere was low but during the industrial revolution the amount of carbon dioxide in the atmosphere rose up a lot and the climate started to change and get warmer. Humans did actions such as burning fossil fuels, and deforestation which warmed the earth at a higher rate. Agriculture also creates a big impact on climate change. for every second that passes, about 1 football field of forest is cut down for agriculture. most of the crops are grown for animal feed. Animal agriculture is one of the leading causes of climate change. The demand for animal products is high, they have to raise a lot of animals. The animals eat and drink a lot, and they produce a lot of methane which is 80x more harmful than carbon dioxide.

Humans effect on climate change

Humans have negatively affected the climate for years, these actions inclue burning fossil fuels, deforestation, and over use of our resources, as the earth warms more and more each year our ice caps will melt even faster.

I completely agree with you. However, I'd like to add that agriculture also plays a big impact on the environment. For example, if you feel bad when you take a long shower or leave the tap running then consider the animal products you eat - eating one hamburger is equivalent to two months of however much the average person showers. That's a lot of water, think about it. Of course, burning fossil fuels, deforestation and the over use of resources are huge problems. In fact, these practices are all used for the making of meat/dairy products - we cut down forests so that we have more farmland, we burn fossil fuels to transport the goods, and of course we use tons and tons of feed (that could go to humans) and water to sustain farm animals.

Is climate change human caused?

Yes. I fully believe that humans are the main cause of climate change. The reason for this is because most of the carbon dioxide in the atmosphere is caused by humans. Humans cause CO2 to be released by cutting down trees for various reasons (ex. clearing land for agriculture, paper production), breeding animals for meat consumption, burning fossil fuels (ex. transportation, heating), electricity use, and so much more. I feel that if we were to reduce some of the things we do to contribute to the CO2 in the environment, then the world would head towards a cleaner and safer future.

If you are a student, you may not think that you can do much to help out, but there are many things you can do including eat less meat, take shorter showers, turn off any electrical device when it is not being currently used, take public transportation, walk, or bike whenever possible, and throw your waste in the right bins. I'm not telling you to change your whole lifestyle, but if we all try to reduce even a little bit of the things we do to contribute to climate change, then we can make a huge impact to change the outcome of the future. Try to do whatever is possible for you.

Climate Change is Real and Human Caused.

Now more than ever, we are hearing about climate change. With our warmer winters and scorching summers, it makes since that climate change is happening. However, some people doubt that climate change is even real, or that it is caused by human activity. This can be a dangerous mentality to have, as the more people that don't believe in climate change, the less that will be done to change it. So, what is climate change? Climate change is caused by an increased amount of methane and carbon dioxide in the atmosphere. These gases trap heat from the sun in our atmosphere. While the atmosphere is designed to keep some heat from the sun, the introduction of the gases causes it to hold on to more than we can stand. The increased amounts of these harmful gases in the atmosphere are mostly caused by human activities, such as driving gasoline-powered vehicles and burning coal at power plants and factories. The more the overall temperature of the Earth rises, the more animals and ecosystems that will suffer because they are unable to adapt fast enough to the rapid changes. To sum it all up, climate change is very real and caused by human activity. If nothing continues to be done about it, we will eventually experience another mass extinction, much like the one the dinosaurs experienced.

Deforestation

Climate change has been a topic heavily discussed more and more lately. There are many factors and people have their own opinions however, when looking at the data it points to clear conclusions. One way that humans are constantly contributing to the rising of climate change is through deforestation. Forests and wetlands are currently being destroyed in order to make a profit from logging or construction. They do this from a process called clearcutting which is when every tree or native plant is destroyed within a single area and nothing is left. This destroying process is very harmful to the environment for many reasons. One way it is very bad is that it takes away animals and plants habitats where they found refuge in and built their habitats. Another way it is very harmful, is that trees have the ability of taking in carbon dioxide and storing it at ground level or underground but then once trees are cut down and dug up it is releasing all of the carbon into the atmosphere. All of the carbon then can be very harmful to the rest of the environment and people which contributes to climate change. Even where I live, you can see deforestation happening at lesser levels. Currently a bridge is being built and so they are destroying large parts of the forests by cutting them down and then holding controlled burns. There are also many developments that are being placed around the city and region in order to hold all the people that are moving here which requires the destruction of forests. Deforestation is a large issue and we need to begin taking care of our trees and saving our parks.

Climate change is real

While climate change does occur multiple ways that do not involve humans, we do significantly accelerate it. In moderation things would not so drastically change, but because we humans refuse to change our ways, the Earth is heating up at an uncontrollable rate. Greenhouse gases are naturally emitted into the atmosphere from decaying organisms and waste. Humans are taking advantage of the Earth and are emitting more greenhouse gases than the Earth can handle. This is deteriorating the ozone layer, leading to overheating and harmful UV rays entering the atmosphere. With the temperatures rising and conditions worsening, humans are digging themselves into a bigger and bigger hole that soon we will not be able to get ourselves out of. Humans must accept that we are the cause of the Earth's slow death. If we do not change this soon, the Earth will not survive much longer.

Climate Change is our Reality, but It's Not Just Us

Climate change happens naturally in multiple ways, like the release of Methane from cows, but we humans excel the rate for global temperature rise by multitudes. We use machinery and factories that release hundreds of tons of CO2 and other green house gasses. The gasses are great at trapping temperature because they're magnetically of balance with their charges. When heat hits them the jiggle and trap the energy in heat form. Ultimately this causes the globe to rise in temperature slowly. To conclude, yes  climate change is real, and when it comes to thee question of if we're to blame, majority answer is yes.

I completely agree with you, some change is completely normal, but humans speed up this process extremely.

Cut Back On The Dairy

I know that everyone likes ice cream, milk, Mac n' Cheese, and just cheese in general--- but have you ever thought about how it affects the climate? Cows--- the source of all our dairy--- release methane, a global-warming inducing chemical, through their digestive system.(As in, when they b*rp or far*...) Personally, I am the only dairy eater in a lactose-intolerant family, but I still feel that we could cut back on the dairy so that farms don't breed cows so much, and so (Hopefully) the amount of methane going into the atmosphere will reduce. (Lactose-free ice cream is good, people!) This is just a thought, but personally, I will try to cut back on the dairy. A pebble in the ocean still creates a ripple! Thanks for hearing me out, and if anyone has any other ideas that don't involve giving up cheese for the sake of the world and reducing methane, I'm all ears!

Planes affecting the carbon footprint

Plane rides are one of the most carbon-emitting ways of transportation. From my personal carbon footprint, my transportation section was up around 6,000 kgs more than normal because I took many plane rides around the world. According to billiontrees.com, a plane emits around 90 kg of C02 per hour. To put that into perspective a normal car emits around 1 kg of C02 per hour. Planes emit way more carbon because they burn a lot more fossil fuels than any other type of transportation. A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Although it is hard to avoid plane rides, the next time you are on a plane think about how much carbon the plane is emitting into the

Archer H   2024-09-25 09:27:23

Yes!! I recently calculated my carbon footprint and was shocked to see how much a couple airplane rides a year shot it up more than 5,000 kgs. Over 16 million flights per year are handled by the FAA which is a huge amount of carbon emissions. As you said plane rides are essential for our worldwide travel, but we do need to consider how much carbon we are emitting every time we fly, even short distance flights.

Char B   2024-09-26 20:34:55

I completely agree that air travel is one of the largest contributors to carbon emissions. Your personal experience highlights just how significant the impact can be. The comparison between planes and cars really puts it into perspective—it's startling to realize how much more CO2 planes emit. Given that many of us rely on flying for both work and leisure, it’s crucial to be aware of the environmental cost. While it may not always be feasible to avoid plane travel, being mindful of our choices can help us mitigate our carbon footprints. Perhaps considering alternatives like trains or limiting long-distance trips could make a difference.
