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 Change Real & Human-Caused?

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.
Hello, I would also like to add a few examples of humans negatively impacting the earth. One prime example of this that comes to mind is the Holocene, known as the current geological period on earth that had allowed for the Anthropocene to come (David Attenborough, A Life on our Planet). Although geologically we are still in the Holocene, the Holocene epoch was very different than it used to be 11,690 years ago due to us humans destroying habitats and killing various animals. A more specific example of this is how the California plains with many wild bison were killed because of humans making space for agriculture and homes. (David Attenborough, Planet Earth, Season 1, The Great Plains).
I agree with you Latiao_strips, that humans play a major role in climate change, and you explained the connection between fossil fuels, deforestation, and agriculture really clearly. The jump in carbon dioxide since the industrial revolution is especially strong evidence—scientists can see it in ice cores and direct measurements from places like Mauna Loa, and those increases line up with when we started burning coal, oil, and gas on a large scale. I also think it’s important that you mentioned methane from livestock, because a lot of people don’t realize how powerful that greenhouse gas is compared to CO₂. We can already see the effects you described in things like more intense heat waves, stronger storms, and melting ice. It makes me think that individual choices (like our diets or energy use) and bigger policy changes both need to work together if we want to slow this down.
Climate change is defined as a long term shift in global climate caused by human activity. This definition proves the fact that climate change is human caused. This still does not explain if it is real or not. A trend since the start of burning fossil fuels during the 1800s shows a drop in global temperatures. The drop in climate is directly related to human activity such as burning fossil fuels. According to NASA, “The current warming trend is different because it is clearly the result of human activities since the mid-1800s, and is proceeding at a rate not seen over many recent millennia.” another quote that also proves the correlation between burning fossil fuels and climate change from clientearth.org, “The Intergovernmental Panel on Climate Change (IPCC) has found that emissions from fossil fuels are the dominant cause of global warming. In 2018, 89% of global CO2 emissions came from fossil fuels and industry.” This shows the correlation between climate change and burning of fossil fuels by proving that fossil fuels releases the most greenhouse gases. Those greenhouse gasses are what cause the change in the global climate.
According to records, 100-200 years ago, the maximum high temperature for my city (Sacramento, CA) throughout the entire summer was around 100 F. Now, however, we regularly see temperatures in the hundreds each summer, sometimes even seeing temperatures above 110 F (115 degrees Fahrenheit a few years ago), which leads to drought and wildfires, among other things. One danger that this causes for humans is that when wildfires occur, the valley in which we live in traps the smoke like a bowl, causing risk for things like lung disease for the residents of this area.
It's more than obvious that the ozone layer is the most important thing that we have in the earth's atmosphere.But what's happening to it? Well, for beginners, climate change is rapidly increasing throughout the carbon footprints.Around the whole wide world, by the emissions of many greenhouse gasses all over the world. But the main cause of this is human population, but how does this contribute to climate change?At all, let's start with the basic over consumption and fast fashion. Fast fashion is clothing that is only popular for a short while, which means that half of the clothes that people buy that are fast fashion, end up going into wastelands, which then get led into the ocean leading up to more waste in the ocean. Which then admit more greenhouse gases By the heat coming for off the clothes, repelling from the sun's heat out into the atmosphere again. But fast fashion isn't the only thing caused by the human population.Another thing caused by the human population would be the increase of demand and food.Since many people are reproducing having more kids making a bigger family.The demand in food has been growing rapidly. The demanded food also contributes to the demand in farming supplies being need, this excludes non electric farming utilities and farming equipment, not powered by gas. The tractors that are being used to fertilize crops and collect crops. Admit tons of carbon out into the world, because they use gaps, which then forms smoke and is set out into the environment, which then thins our ozone layers. The protecting us from space, which means that the great a nation's population is the higher demand of food. Which then leads to a higher admission of greenhouse gasses, which in all contributes to climate change. Well, all these explanations muster up the question is climate change even real and how so? The way that we know that climate change is really because over the years of after the industrial revolution.When the rise of human population was increasing rapidly, the ozone layer began to thin out.Because of the carbon emissions created by the greenhouse gases, which caused the earth to get hotter by the ozone layer, trapping in all G.H.G which Caused our planet to heat up. This is how we can tell that not only is climate change. Real, but that it was increased rapidly by humans, meaning that climate change is real.Not just tyat but it is human caused this doesnt mean that it's only caused by humans, but that the main cause of climate change is mainly humans.
yes
I agree
Yes it is.
yes, all the pollution in the oceans and a lot of the CO2 in the air was caused by us.
I believe it is due to our large carbon and fossil fuel emissions, constantly warming the planet.
It is caused by us. Via big corporations polluting the atmosphere, and the average persons daily life impacts the C02 pollution as well.
yes
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.
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.
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.
I completely agree Humans have single handed raised the ppm of CO2 by almost 125 since 1960
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
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.
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.
I agree I think that humans cause all of our earths problems. Things need to change before we could help stop climate change.
yeah lots of things we do need to change like factories and stuff that produce CO2.
I agree that climate change is human caused, but its mainly big corporations, not necessarily one person.
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.
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.
yes it is
Yes everyone contributes to climate change with their C02 emissions, but the largest contributors are major companies like Amazon, Microsoft, and major oil companies.
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
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.
I learned that I don't recycle as much as I thought and will try to do a better job at recycling
No you should be gud brochacho
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.
