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?

is climate chnage real and human caused

yes

Ariana17   2025-09-24 10:10:20

I agree

elih2011   2025-09-24 11:00:36

Yes it is.

HuckSharaf   2025-09-24 11:39:45

yes, all the pollution in the oceans and a lot of the CO2 in the air was caused by us.

1mmkindred   2025-09-24 11:41:47

I believe it is due to our large carbon and fossil fuel emissions, constantly warming the planet.

jacksonsmedley   2025-09-24 19:13:18

It is caused by us. Via big corporations polluting the atmosphere, and the average persons daily life impacts the C02 pollution as well.

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.

wyatt graybill   2025-09-24 17:45:26

you're right, we are causing far to much CO2 to enter the atmosphere and this needs to stop. while personal action will help there will always someone who doesn't care, which is why big corporations also need to play a role.

jacksonsmedley   2025-09-24 19:11:37

I agree as well, we are causing way to much pollution and C02 to enter our and atmosphere. And we need to do something about it. We need to get big groups of people to help the cause, while individual help and still impact it. Bigger groups get attention better than just one person.

NateHooper   2025-09-25 13:02:37

I completely agree Humans have single handed raised the ppm of CO2 by almost 125 since 1960

climate change is human caused

climate change is human caused because we breathe out carbon no mater what so every breath you take adds on and on and on so even if you try your most to live a life trying to not "contribute" you still will

Ethan3214   2025-09-24 11:47:48

Climate change is somewhat human caused. Climate change itself was going to happen just from natural events that heat up the climate. However, humans have greatly sped up climate change with gas cars, factories, and fossil fueled powered things. So to answer your question climate change happens because of natural events, but humans have sped up the process of heating of the earth due to what we use as fuel.

climate change is our faults...

I believe it is caused by humans because apart from necessary things we need in life, we’re creating/doing unnecessary things and hurting the environment more just for our entertainment that don’t even always last.

nerdypigeon   2025-09-24 09:24:25

I agree I think that humans cause all of our earths problems. Things need to change before we could help stop climate change.

sean1111   2025-09-24 09:58:51

yeah lots of things we do need to change like factories and stuff that produce CO2.

Grace Osborn   2025-09-24 11:37:37

I agree that climate change is human caused, but its mainly big corporations, not necessarily one person.

Is climate change real and human caused?

Yes, everyone has a carbon output which attributes to climate change, these carbon emissions contribute to climate change by adding carbon dioxide to the atmosphere. We can all reduce our carbon emissions by using electric cars or things that don't put as much carbon into our air.

nerdypigeon   2025-09-24 09:27:39

yes everyone contributes to co2 emissions and this warms our planet. we need to get group action involved to stop climate change from hurting earth permanently.

August1202   2025-09-24 09:53:01

yes it is

camcameron2525   2025-09-24 09:55:50

Yes everyone contributes to climate change with their C02 emissions, but the largest contributors are major companies like Amazon, Microsoft, and major oil companies.

sean1111   2025-09-24 09:56:44

yeah its real cause everything with technology has some impact on the environment which makes the planet hotter. i saw this article that says phyto plankton that supplies 60% of the oxygen we breath will die if the planet keeps getting hotter

Is climate change real and Human-Caused?

YES, it absolutely is. Humans are the main cause of climate change, but there may also be some natural causes too. So the answer is mostly.

The Carbon Cost of Flying

Air travel is one of the most carbon-intensive activities an individual can engage in. According to the International Air Transport Association (IATA), commercial aviation accounts for about 2–3% of global CO₂ emissions, but its overall climate impact is higher due to the release of other gases at high altitudes, which amplify warming effects (Lee et al., 2021). Air travel has become an integral part of global connectivity, enabling economic development, cultural exchange, and personal freedom. However, its environmental cost—particularly in terms of carbon emissions, is significant and often underestimated.

Would Climate Change occur without Human intervention?

Climate change is a very real and is mainly caused by humans, although many people are doubtful this is even occurring. Climate change is the long-term change in Earth’s temperature, weather patterns, and climate systems. According to NASA and the National Oceanic and Atmospheric Administration (NOAA), the Earth’s average temperature has increased by about 2 degrees Fahrenheit since the late 1800s, and most of that increase has happened since 1975. This is due to the pollution from cars, factories and power plants. However, there have been natural factors that contribute to climate change such as volcanic eruptions or changes in the sun’s energy. While these might not be the main causes, they do speed up the process. Without humans, climate change may occur over many years, but nowhere near as quick or devastating as it is now.

I agree with you. Climate change is 100% human caused. But I think one of the main issues is that it’s hard for humans to change their whole life styles. Since climate change is such a big and important issue, it does take immediate action but humans are hesitant to be the change and try and combat climate change. I agree that everyone should do their part in helping fight climate change, and I liked the ideas that you suggested. Some more possible ideas of specific actions you could take are planting a garden to grow your vegetables so that they won’t need to be imported from other countries and grown with harmful chemicals. Like you said, people should try and eat less meat, as the meat industry, specifically cow agriculture, is one of the leading causes to climate change. Of course it is hard to get people to change their diets, but in order to combat climate change I do think that it is necessary.

Paula T.   2025-05-01 08:19:42

Hey there!

I agree with the most of the arguments. However, climatic change has happened in the past, such as during the ice age.  The current climate change is definitely caused by human society. As it was pointed out, it would be hard for everyone to change their lifestyle in order to reduce carbon dioxide pollution. Companies that produce a lot of products tend to be reluctant to reduce CO₂ emissions. Since the filters and other elements they would need are actually expensive. Fast food companies, for instance McDonald's, in the USA produce lots of CO₂ due to their cow stock.

mayag1122   2025-05-15 14:46:41

I agree. Climate change is most likely caused by humans because in the past, mostly natural gasses were going into the atmosphere which allowed for them to be naturally broken down over time. When humans came into the equation, we began to cut down trees which made it so the CO2 we breathed wasn't able to be consumed and we released fossil fuels from underground that wouldn't be going into the atmosphere as quickly without us manually doing it.

Personally, the most that I contribute to climate change is by taking flights and going on vacation. I wonder if there's any way to create electric planes that are able to travel long distances so that it would be more sustainable for the environment.

EtKwBOD   2025-05-15 17:00:05

I agree with you 85%. Climate Change is mostly caused by humans, with our factories and carbon emissions contributing a lot. However, natural weather is also a small factor when it comes to Climate Change. Natural disasters such as wildfires are caused by high winds, which we have no control over. The burning involves a chemical reaction where the carbon in the wood combines with oxygen, forming CO2. Overall, I think that Climate Change is caused by humans, but some natural causes contribute to the change.

RoJBBOD   2025-05-15 17:22:31

Yes I do think Climate Change is mostly human caused. Climate Change is caused by the rising amount of greenhouse gases that are in the atmosphere which causes heat from the sun to be trapped in the atmosphere instead of going back out into space. This is making the heat to rise or, global warming. To answer this question fully you must understand that Climate Change and global warming are two different things. Climate Change refers to the change in climate while global warming refers to the rising temperatures of the Earth. Global warming is part of Climate Change so they are relational. Although, Climate Change is not completely human caused, natural things happen on Earth that cause Climate Change as well. Overall, I'd say Climate Change is 90% percent human's fault and 10% natural cause.

Climate change

I think climate change is caused by humans because life is a simulation that the government is doing to distract us from the real world

CroDude   2025-05-02 12:03:04

While everyone is entitled to their opinion, it's important to separate science from speculation. The overwhelming consensus among climate scientists is that climate change is primarily driven by human activities, such as burning fossil fuels and deforestation. Ideas about life being a government-run simulation are not supported by credible evidence and distract from addressing real-world issues that urgently need our attention.

Warming Planet

Yes, climate change is real and caused by humans, and with the years it is getting worse and worse, negatively affecting our planet and us humans. It is sad that we no longer even have four seasons — spring has become summer, while winter is more like autumn. Even if we start taking better care of the environment now, we will not stop the melting of ice and glaciers. Although we cannot undo the damage, we can still slow down climate change if we all start taking action now.
