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?

Fossil fuels

Fuels are burned to make energy. They release carbon dioxide into the atmosphere which hurts the planets environment by increasing the temperature. We need to stop burning fossil fuels and switch to a different energy source like solar power.

Mikay   Yesterday 22:57:07

I totally agree with you. Fossil fuels and sedimentary rocks were not made to be burnt and used the way us humans are using them. Nature has a way of dealing with things and that is how it use to deal with carbon dioxide. The rocks absorb and store carbon dioxide. This process took millions of years of work and humans have been burning these fossils for daily use (as an energy source), destroying so much irreversible work. I also agree that we should switch to a different energy source like solar energy or windmill energy, however the way these things are priced is unrealistic. Solar panels have a high price rate as well as a high maintenance consumption. This causes some annoyance for some people and for others it may cause financial instability. Even though some have both the patience and money, they may not have the time to clean and set up the solar panels. This issue is not widely discussed, but I believe that if the government or solar panel companies could lower the price or/and be available to set up and come clean the panels every so often more people would be willing to switch their main energy source to try to help slow down climate change.

Climate Change is real

People believe that climate change is fake because they argue that it's still -10 degrees outside. That's the weather. Weather and climate are two very similar, but different things. Weather is the temperature of the current day. Climate is the temperature, precipitation rates, storm possibilities, and more. Climate tells us what the average weather will be for a certain time period. Over the years, we have seen the climate increase and more and more carbon dioxide gets released into the atmosphere.

If climate change is fake, then are the ice caps melting? Why are coral reefs going extinct? You may think that increasing the sea levels by 2 meters is nothing, but the effects are catastrophic. Many parts of the world including Florida, Miami, Bangkok, and more will be underwater. So what? Who cares about these cities? It's not about the cities. It's about the people. Who will pay for all the damage caused by these floods? Where will all the people populating the cities go? If we do not do something now, it will become much harder later to fix these problems.

Exactly, People really need to open their eyes nowadays, we are heading into a dark future. I hope to live in a future where my future grandkids will be able to see snow. I have a half-sister that dreams of seeing snow someday. As our carbon emissions go higher than ever recorded, I don't think it will be possible in the future unless we act now. Can you believe that after the industrial period, we have produced over 1,800 GtCO₂ which is 37.8 billion metric tons. How will we ever recover from this. As sea levels rise, i feel like more people are covering their eyes and ears as they don't believe this is really happening. 99% of scientists believe that climate change is real, but why don't the people believe? I'll tell you why; they are too scared to realize that us humans will go extinct in a matter of a few decades if we keep up our carbon emissions. There are ways we can reduce carbon, A bunch actually, but people live too lavish to care. If we can't do something about this right here and right now, our species is done. Mother nature can live without us. But we can't live without her.

Adddison   Yesterday 21:13:28

Yeah, I strongly agree with what you guys are saying. We need to wake up to what climate change is doing to our planet,and not just in small places, like the pacific islands or the Maldives that don't really affect a large number of places, but everywhere. People have ignored the problem for so long, only because it didn't DIRECTLY impact their daily lives.And only now are people realising that this is real and they suddenly have to do something about it. But what about the people who have already been suffering for years, who had to move because rising sea levels made their country go extinct. These people have been trying to tell us for years that climate change is real, we are the problem, but we haven't listened until now. We all have to do something now to stop climate change before it's too late.

Climate Change is definitely real

Climate change is real and also primarily caused by human activities. Scientific evidence from many sources, like ice cores and satellite data, can show that the Earth is warming at a faster rate due to human activity and the expansion of the greenhouse effect. The main factor of this would be the burning of fossil fuels like coal and oil, which has significantly increased the amount of heat-trapping gases in the atmosphere.

Tyrone J   2025-11-13 22:04:40

I agree climate change is a problem we can no longer side line. Although there are scientists working on this issue right now there is not nearly enough. Climate change as a problem is being completely underestimated. Human activity and expansion has caused more harm than good for the very environment we live in. The greenhouse gas problem has gotten completely out of hand. Even though, there are solar panels and some sources of green energy it is not nearly enough. I am confident that with enough attention and resources we could effectively find a better source of green energy or refine the things we have already.

Jigesh   2025-11-14 12:00:40

I would agree with you on the point that climate change is real and human accelerated. Also, I think that it is very frightening that many people don't believe this. Finally, I would like to applaud you for your use of citing the scientific evidence of ice cores and satellite data.

MHRC   Yesterday 15:40:19

I agree with this. Climate change is very real, and very much human accelerated. The earth's temperature is about 1.42 Celsius warmer than it was before the industrial revolution, when we started burning fossil fuels. Human actions are the reason that the earths surface is warming and for many animals going extinct. By 2050 it is estimated that during the summer, we will be able to sail across the arctic.

E80

To reduce emissions, my family has switched to a car that is capable of running on E80 instead of an electric vehicle. Electricity is still mainly produced using coal and other fossil fuels which are less efficient than burning it directly in a gas powered car or a hybrid vehicle. Even more, these fuels such as coal and oil are non renewable whereas E80 produces less CO2 than pure gasoline and is mostly made of ethanol which is renewable.

Can we stop using fossil fuels?

Fossil fuels are the main cause of rising temperature and climate change. Burning them for energy releases large amounts of greenhouse gases into the atmosphere. Since we use fossil fuels for many different purposes, like industrial processing, energy production, and transportation, we can't immediately stop using fossil fuels. But if people will slowly change, at first, energy production, then use this energy for industrial processing, and change all cars, and other transport to electric ones. Then this will help our planet a lot.

Eric N.   2025-11-14 12:02:46

I think that this is an issue that needs to be addressed. However, I think this problem would be better handled regionally, not globally. I live in an area that produces almost three times as much carbon per year than average. I think that we would need to bring the carbon emissions average down by drastic changes in smaller regions. This is because it is very hard to accurately judge progress on a global scale. This could lead to inaccurate data.

Climate Change Is Real

Climate Change is real, it is occurring at a fast rate. The planet's average surface temperature has risen by about 2 degrees Fahrenheit since the 19th century. Ice has been melting in Greenland and Antarctica are decreasing in mass. The royal society has an article about the basics of climate change, for example, greenhouse gases affect Earth's energy balance and climate. The sun is Earth's primary energy source, much of that solar energy is re-emitted into heat, this goes with the greenhouse effect because greenhouse gases are polluted gases in the atmosphere that absorb the heat energy and emit it, adding more greenhouse gases to the atmosphere enhances the effect, making the atmosphere even lower. If we put an end or even limit our greenhouse gas use, we can heavily impact a change.

Climate Change is Very Real

Yes, climate change is real, and the evidence shows that human activity is the main cause. Scientists have studied global temperature records, ice cores, ocean temperatures, and atmospheric greenhouse gas levels for decades. These studies show that the Earth is warming faster than it ever has in natural cycles, and this warming closely matches the increase in carbon dioxide and other greenhouse gases released by humans through burning fossil fuels, deforestation, and industrial activity. Other evidence includes shrinking glaciers and ice sheets, rising sea levels, more frequent and intense heatwaves, stronger storms, and changing weather patterns that are all consistent with what climate models predict for human-caused warming. While some people may question the science, the overwhelming consensus among climate scientists is that climate change is happening and humans are largely responsible. Understanding this evidence is critical because it guides the actions we take to reduce emissions, protect ecosystems, and prepare communities for the impacts of a changing climate.

Climate Change Is Real and Humans Accelerate It

Climate change is a very real issue and people who deny its existence have not seen the effects or the data. There is undeniable proof that climate change is real however, the question lies on the idea of whether the entire thing is humans fault. Climate change in itself is not human caused it is a thing that would have occurred in nature over the course of millions and billions of years. Humanity as a society is rapidly increasing the rate at which this natural process takes place. We deforest and destroy numerous natural habitats that would have significantly slowed the process by cleansing the air. Not only that we release mass amounts of carbon dioxide and other carbon compounds like methane into the air in large quantities every year. We pollute and destroy water ways and the aquatic life in them by using pesticides and dumping chemical waste which in the end does lead to a rapid increase in the pace that climate change accelerates by further destroying the environment around us. So to conclude climate change is real and although not human caused, is rapidly increasing the natural process where climate change takes place because of human intervention and destruction.

Climate Change

Yes, climate change is real, and is at minimum, 95% human caused; This is because of our man-made inventions like factories and vehicles/transportation that emit greenhouse gases into the atmosphere. Our man-made inventions negatively impact many environments, for example, the most popular environment impacted being the arctic and its glaciers.

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.

Maeha   2025-11-12 16:22:39

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).

AGsjrstate   2025-11-12 19:30:46

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.

Jgesell -sjrstate   2025-11-13 18:52:56

You're absolutely right, humans are to blame for the rapid rise of climate change. The sudden rise after the industrial revolution is enough to clearly indicate that we have directly affected our atmosphere. Everything from the transportation to the food we eat and the products we buy, almost all of it negatively impacts the environment. I think nothing is done by a lot of people to slow down their emissions because it can feel futile to try and stop something that's going to happen regardless, and this feeding into nihility is going to kill our planet if nothing is actually done about it.

What exactly do humans do to contribute to climate change

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.

Climate Change in my city

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.
