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.

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.

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.
