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 is definitely real, but it is a natural process. According to the OSS Foundation, it is normal for the earth to go through cycles of warm period and ice ages. Humans; however, are speeding up the process. According to OSS the earth goes through cold and warm cycles every 100,000. We are currently in a warmer cycle, but have already reached the maximum point 10,000 years ago thus the earth should be cooling down right now. Unfortunately, instead of decreasing it has been increasing because of the amount of fossil fuel burning that has been taking place. Climate change may be a natural process but humans are interrupting the natural flow.

This is true. People should pay attention to that
http://www.sciencedaily.com/releases/20 … 094511.htm Here is an article about how southern hemisphere ocean is warming more than scientists expected. People are ignoring the issues of climate change, saying that is a myth, when evidence is everywhere, literally.
It's an interesting thought, and it's true. What's more interesting about this is that people aren't paying as much attention to this idea as they should. Humans aren't exactly looking into this point. Instead of focusing on if climate change is real, because it clearly is, people should be focusing more on how to let the natural process remain at least slightly more natural than it is.
Humans should be blamed for a portion of climate change, as they are, without a doubt, the ultimate cause of events such as the Great Melt (Greenland in 2012), or other global warming occurrences. The smog from factories and other industries are released, heading north to the snowy areas, and darkening the snow, lowering its reflectivity and letting it absorb heat more. If one were to be extremely technical, yes, humans are ultimately the "cause" of climate change events such as this, but as you stated, climate change is a natural process, and humans are only affecting it, not causing it.
I kindly disagree Borami S, humans most definitely have their fingerprints on this one. Yes the climate has both natural and human effectors, but I think that the humans have the upper hand. As the population grew the amount of CO2 in the atmosphere has. The CO2 is what is causing this annual heat which is higher than before. On a chart the CO2 right now and the past decades is astonishingly higher than ever. But who is releasing this, IT'S US, we are the ones causing problems.
The ocean's have absorbed 20 times more heat than usual in the last half a century. Also the Carbon Dioxide is residing in the ocean increasing the acidity. This makes ocean life that grows shells and other apparatuses have developmental issues, decreasing it's likelihood to survive well into adulthood. Our habits and behaviors have also cause us to lift the ceiling of the lower atmosphere, helping trap heat. The average global temperature ass risen 1.4 degrees Fahrenheit, with the bulk of it happening in the past three decades. We can't reverse this process but, we can lower it for the future.

Wow! I didn't know that the earth was actually supposed to be COOLING DOWN! I always knew that the earth went through natural patterns of climate change, but what with global warming and all, I never realized that the earth might actually be supposed to be getting colder. I definitely believe that humans are affecting the "natural flow" of the climate.
Humans are the reason that glaciers are melting. We're the reason that wildfires and droughts are becoming more common. We're the reason that the oceans are rising and becoming more acidic. It's up to us to stop it by preventing the amount of greenhouse gases we emit each day. If everyone does their part, hopefully we will be able to be able to get climate change patterns back on track.
THANK YOU! Finally, someone who actually has both opinions. The earth has a cycle that moves over the years. Yes, we do effect it and I really do believe that we need to stop effecting it so much. We are not listening to the people around us. We are kind of just sitting around and letting it happen. We should find a way for more people to be able to get to people around the world.
Many people state that we are the entire cause of climate change, but that is a lie. We effect some of it but our life every day isn't going to change because we are on the computer longer. Think of life would be like without clothes of food because we can't use factories to make it. So my conclusion is we do have an effect but climate change is mainly a process and we can't change anything about it now.
Borami S,
While you are correct in saying that the earth goes through periods of immense climate change, humans have a larger effect on the process than you let on. Around 55 million years ago, the earth went through a period of time known as the Paleocene Eocene Thermal Maximum, or PETM. During this era, the earth's carbon dioxide levels were even higher than they are now, but there's one big difference: the temperatures now are rising so high at a rate that has never been seen before, that organisms are not able to adapt fast enough causing more extinctions and disruptions in the food web. During PETM, that was not the case. Humans are speeding up the process dramatically.This is most obviously seen in the oceanic ecosystem.
I've recently read an article about the acid levels in the oceans and how they affect that environment. In the article, a team of scientists traveled to Castello Aragonese, a small island area at the northern end of the Gulf of Naples. Volcanic sea vents underneath the surrounding water release bubbles of carbonic acid providing us with a wi ndow of what our oceans will look like by 2050. The author describes the ocean as very lifeless. All that was visible was clusters of barnacles and transparent jellyfish. This shows that in 36 years, our increasing levels of carbon dioxide in the atmosphere will create a desolate and barren ocean. If we don't find way to lower our CO2 emissions, it may be too late for all these creatures.
