Discussions Discussion Is climate change real? Is it mostly human …
Billy Angelou, Feb. 27, 2014

Climate change is first and foremost an issue because people can’t even agree on whether or not it’s an issue in the first place. Before we even get into the solutions, we all (regardless of political party) need to come to the realization that yes, climate change is real and yes, it is affecting us in ways that we can see and feel. If you still believe that the freakish weather and heat waves we’ve been experiencing have nothing to do with climate change, you might want to ask your neighbor what he or she thinks because the majority of Americans now say they believe global warming is causing these incidents.

    Yep. I love how people seem to adopt this ideal of selective ignorance, as if to hide the fact that they're gradually hurting the earth with their own poor decisions. Climate change is real, harmful, and unfortunate, and we need to do what we can to slow or prevent it. A good start is to just come to agreement that it's a real dilemma, and then go from there.

Maxwell Coon, Oct. 25, 2013

Many people hold onto the notion that climate change isn’t caused by humans, or isn’t happening at all. Climate change is absolutely happening, and humans are the primary cause. Scientists have theorized since the beginning of the 20th century that the use of coal and fossil fuels could have an effect on the climate of the earth. Later it was shown that carbon dioxide rising into the atmosphere traps heat that would have left the atmosphere, which causes global climate change. In the 1950’s scientists directly linked the increase in carbon dioxide in the atmosphere to the fossil fuel emissions of humans. Scientists across the world all agree that these fossil fuel emissions are the leading cause of global climate change, and there is literally no evidence that has contradicted the ideas and principles of climate change. As soon as we realize that climate change is in fact happening the sooner we can start taking steps to meet the affects it will have on the world, and try to limit the damage.

    Hi Maxwell
    You are so right and I hate how people think that the scientist are making this thing up and that it's not the humans that are causing this because we are causing this and we have to change this.
  • Caitlin Bond Caitlin Bond Feb. 26, 2014
    Maxwell, I completely agree with you! Climate change is a very real issue that needs to be addressed soon before it becomes a problem we can no longer tackle or take control over.
  • Maddi Ownbey Maddi Ownbey Feb. 27, 2014
    Hey Maxwell, I agree with you completely. We as humans do not understand the impact we have on the environment around us. Everyone needs to figure out how to reduce their carbon footprints. Carpool, walk, ride a bike, there is so many ways to reduce using the gases that are burning away our atmosphere and are causing global warming.

Climate change is going to affect our future. We need to act on this now if we are going to do anything about it. Many people are denying that we humans have such a big impact on global warming, these people are too scared to take fault into their own actions. We have to learn off of the facts, and look at how these wildfires are causing glaciers to melt at such a rapid pace, increasing our sea level. We have to have to change how we live so our ocean is not polluted with a million pounds of carbon every minute! Ignoring this change in our world will not help anything, it will only make things worse.

    Hi Mayzie I’m Giulia from Italy. I agree with you that the climate is changing because the glaciers are melting, there are too many wildfires and the sea level is increasing because there is too much CO2 in the world and I think that our planet can’t withstand all this carbon! The scientists are looking for a way to burn the hydrogen to produce water and minimize carbon emissions because the water isn’t pollutant. The hydrogen might be the alternative fuel in the future.
  • Tessa Stefan Tessa Stefan Feb. 19, 2014
    Hi Mayzie, I am Tessa from Germany and I absolutely agree with you. I think most people do not want to change their lifestyles. Using the car is really comfortable and I guess most people do not want to relinquish their comfort because that is the way with fewest resistance.

Yes, I do believe that climate change is real, and so do scientists. According to real Climate (“RealClimate: September, 2013.” RealClimate RSS. N.p., n.d. Web. 08 Oct.), in September scientists came to a conclusion that humans are 95% sure HUMANS are the cause.

Though I do see where the other side is coming from. Many events, such at PETM (a 10+ degree Fahrenheit jump in only a couple thousand years), have caused some to believe that the world is just going through a hot spell, rising a little bit quicker than normal.

While both these arguments have their truths, I have to say the change is caused by humans. It cannot be only by coincidence that the steepest rise in temperature ever recorded (the last 50 years) is at the same time where we are all using and burning tons upon tons of carbon dioxide every day, more than ever before.

I think climate change is very real, the cause however is much more mysterious. Humans definitely play their part, but the world has been known to heat and cool over time. With humans polluting the air as we are, though, it’s hard to say for sure. It could be the glaciers melting in Greenland, for all we know.

    I agree that the climate change has been happening even before humans started to pollute the earth, but the glacier that are melting in Greenland are a result of human pollution. Fires in Colorado and Canada are sending a of soot over the tundra, causing the heat to get trapped into the snow and having the glaciers melt.
    The worst part about the climate change is that there are very few people that are informed about it. Scientists are doing their best to alert the public that their planet us slowly dying, but with very few research funds and the amount of donations decreasing, it is extremely hard to make everybody aware.
    Although our footprint on the earth is already huge, we can stilly line complete destruction. Recycling is one of the easiest ways to decrease the amount waste that fill our landfills and potentially go into our ocean.
  • luke lawler luke lawler Oct. 24, 2013
    I also agree that the climate has been changing over time. even though most people blame it solely on human pollution there is more to it that that. There have been discoveries that show that there have been significant climate changes millions of years ago which proves human pollution is not the only cause. but with pollution still affecting the climate i think people play a large role in being able to lower CO2 emission and possibly revering the effects in the future.
  • Vincent Ceja Vincent Ceja Oct. 25, 2013
    I agree with your statement, but there is lots of evidence that shows the effect the humans have with climate change. And the glaciers melting in Greenland are a result of our pollution! In the past years the atmospheric carbon levels have risen equally along with our economical rise. The steady rise of earths industrialization is mostly to blame for.

Climate change is happening. Ernesto Zedillo summarizes the evidence pretty well in his book, Global Warming: Beyond Kyoto. Vietnam’s National Academy of Public Administration hosts a PDF copy that I link to at the bottom.

The temperature rise in the twentieth century was the highest seen in the past 1000 years based on simulated reconstructions of the climate over that period. The size of the Arctic Sea’s ice sheet has dropped by 20 percent in less than 35 years.

The evidence points to humans as the chief cause of recent climate change. Zedillo discusses “forcing”, which refers to any input to the climate. He explains that the warming that’s happened has been close to the amount of warming predicted to result from anthropogenic forcing, or influence on the climate by humans. He then lists sources of natural forcing, which he claims don’t explain the amount of warming we’ve experienced in the past hundred years: “solar activity, volcanic activity, cosmic rays, and orbital shifts.” He goes further to say that the impact of these kinds of forcing on the climate have diminished recently. From this information and the lack of an accepted alternative cause, he concludes that climate change is mostly caused by human activity.

To me, the evidence pretty clearly points to anthropogenic warming as real. A very accurate simulation of how the environment would have developed in the past several decades without the heavy industrial impacts on the atmosphere might convince me otherwise. The result would have to be something close to how the environment actually ended up today.

    Bailey, could you give some warrants for your claim that humans don't cause climate change? Even if we can't avoid temperature change, it's still possible for humans to contribute to it. The evidence I talked about shows that it's not just possible; it's the most likely explanation for the change we've seen.

    Why don't you think rising CO2 levels in the atmosphere cause icebergs to melt? I think the burden of proof is on you here. Carbon dioxide traps excessive amounts of heat on Earth, which melts ice.

    Looking at global warming with a focus on security and policy gives a pretty clear picture of how climate change affects human beings. The Huffington post summarizes different sources' spins on the impacts of warming in a blog post “Climate Terror: Global Warming, Failed States, and the Rise of Terrorism.” The Center for Naval Analysis reported that an increase in the global temperature of 1.8 degrees Fahrenheit would reduce global agricultural output by 10%. The book Climatic Cataclysm uses a report from the World Bank to back its claim that that by 2050, which we'll probably live to see, up to a billion people living near coasts could lose their homes to climate change. The International Water Resources Management Institute predicts water shortages in big regions of India and China, the two most populous countries in the world, by 2025. At best, these effects have severe impacts on the quality of life; at worst, they're deadly. You can check the blog post out for more, but those are the impacts mentioned that will happen within our lifetimes.

    The blog post mentions a couple of the claims made in Climatic Cataclysm, but the book goes a lot more in depth than the post does about how climate change impacts us not just by changing the physical environment, but also by influencing society and people's actions. In the book, Sharon Burke predicts over a hundred failed states due to internal conflicts and extremism. She says that the chaos resulting from people's reactions to warming would put 2.7 billion at risk of violent conflict, either between states or within individual states. Dents in agricultural production and water shortages will hit India hard. This would put huge strain on India's tensions with Pakistan. Both of those countries possess nuclear weapons, and the escalation of clash between the two is one of the most likely paths to nuclear conflict out of the possibilities today. Because climate change would affect hundreds of millions of people in India, Burke asserts that a nuclear exchange in the region would be likely.

    The carbon that we release into the world every day can not be denied or ignored, this is definitely a huge problem that we need to help fix. To say that none of this will harm us is false. Scientists have proof that we are harming our environment by not being considerate to our environment. Our pollution and soot from wildfires has been building up, acidifying the oceans and increasing heat, causing glaciers to melt. It might not seem like a big deal but every cause has an effect. Glaciers melting causes the rise in sea levels, the loss of polar species. Acidifying the ocean leads to a loss in jobs, harm in marine animals. This all leads on and there is only one way to help it, by changing the way we live and making this world wide problem known to the public.

Is climate change real? is it mostly human caused?
I think that humans are a large part of climate change. The attached article discusses climate change and how we are affecting it. The greenhouse effect is a large reason for the increased amounts of CO2. For example, in a graph attached you can see that the amount of ppms of CO2 in the air is increasing steadily. This is caused by factories, burning food and trees, and the growth of the population (which means more people contributing).
Climate change would be have a direct effect on life on Earth. It would raise sea levels which would result in more flooding and unexpected stroms. It would also reduce our amount of fresh water and animals that live in colder climates. We need to go to measures such as not burning forests and using more renewable energy.

These are my references

    Abbey- I agree with you that climate change is a result of the greenhouse effect. Because of the amount of fuels and substances we burn the emissions increase. This causes all of it to get trapped. I think if we switched to a different main source of energy, such as solar energy, we could reduce the rate of the effect growing.
  • Hannah T-USA Hannah T-USA Oct. 9, 2013
    Abbey- I definitely think that humans are a huge part of climate changes! Pollution can be a part of this. Therefore anything such as transportation or factory smoke can play a large part in climate change! http://www.classzone.com/books/earth_science/terc/content/investigations/esu501/esu501page01.cfm

Tara V-USA, Oct. 5, 2013

It frustrates me to no end when people refuse to believe that climate change exists. There is such an overwhelming amount of evidence that proves its existence and the necessity of stopping the trend before it is too late. I recently read an article detailing several different forms of evidence to support climate change. Before I get into that though, I’d like to discuss the reason current fluctuations in climate are different from the fluctuations in climate that have occurred throughout history. As the article I linked below explains, large climate changes in the past occurred over tens of years not thousands and the current increasing change that has been happening for thousands of years shows a gradual warming that is not simply a small scale fluctuation of the past. In addition, past fluctuations are due to slight differences in the position of Earth, which affects the amount of solar energy received. Those differences haven’t changed and certainly wouldn’t be able to change enough to account for the differences in climate we are currently experiencing. Therefore, climate change is definitely happening and the only explanation is human related activities since climate fluctuations are clearly distinct from past ones.

Of the immense evidence provided in the article I have linked below, the most compelling is sea level rise, temperature rise, glacial retreat, decreased densities of ice sheets, and ocean acidification. The sea level has risen 17 inches in the last century, which is an especially striking number when one considers the fact that it only grew about half of that in the prior century. The temperature has risen as well with significant increases occurring from the 1880s. The past 12 years have seen ten of the warmest years in history to be exact despite the fact that the net solar output declining in the 2000s. The fact that solar output, which is the cause of past climate fluctuations, has been decreasing and temperatures still continue to rise, proves climate change is occurring and due to something other than natural causes. This leaves humans as the root of the problem. Further evidence is visible in retreating glaciers in all areas of the world as well as the decreasing ice sheets. In fact, Greenland ice sheets decreased by 150 to 250 cubic kilometers per year from 2002 to 2006. The rate of shrinking ice sheets has only increased. Ocean acidification is a direct result of human activities that emit more carbon into the atmosphere as ocean acidification has risen 30 percent since the Industrial Revolution. The Industrial Revolution increased the amount of carbon emitted by humans immensely and the increased acidification of the ocean can only be attributed to the event. The saddest truth about this ocean acidification is that as the ocean becomes more acidic, it absorbs even more carbon. The fact that our effect on climate change is allowing the ocean to store more carbon and yet we produce enough carbon to still cause massive climate change is ridiculous. We are far outpacing the amount of natural climate regulation that exists in the ocean and we are the root cause of the temperature fluctuation. People need to stop arguing about if climate change is happening and start making changes to mitigate it.

    The main cause of the rising temperature is increased amount of carbon dioxide in the air. Carbon dioxide is a greenhouse gas that increases temperature. The increased temperature could bring disastrous effect to our atmosphere. One of the hypothesis of the extinction of dinosaurs is that the excessive amount of carbon dioxide released by dinosaurs destroyed the balance of carbon in the air and on the ground that caused dramatic effect in the atmosphere which killed all dinosaurs. However, humans are able to devise plans to change the nature, and I think it is our time to become aware of the danger of global warming and advocate people in the world to conserve energy.

Reynolds S-US, Oct. 5, 2013

Is climate change real? Of course! But I disagree that humans are entirely to blame for global warming. Over time, the Earth goes through different phases in which the temperature fluctuates. For example, during the ice age, the Earth was covered in snow in places that are now deserts. But when the ice started melting away and the temperature increased, there were no humans to stimulate the temperature change. This example shows that the temperature of Earth fluctuates periodically. Humans are partially to blame for global warming though. Like Asea said, the “greenhouse effect” plays a major role in global warming. In this, carbon dioxide and other pollutants gets trapped in Earth’s atmosphere, and subsequently, causes a rise in temperature. Other pollutants that get trapped in the atmosphere are produced by burning of fossil fuels such as natural gas and coal. These fuels create emissions when burned that get trapped in the atmosphere. Because of periodic changes in temperature, I believe that global warming is not entirely occurring because of humans, but we do play a big part in it.

    Reynolds- I agree with you. Global warming is only partially our fault- the rest is due to the fluctuating temperature. The ice age is a perfect example of just that.

    However, I also think that we should try our best to stop or slow global warming by fixing some of our human activities. Examples of this would be forestation, factorization, and agriculture. Each of these releases CO2 into the atmosphere where it gets trapped— which is known as the greenhouse effect. If we cut down on these activities, we could potentially help save our planet.
  • Taylor G-USA Taylor G-USA Oct. 10, 2013
    Reynolds-I also agree with you. Global warning isn't entirely our fault. But we do contribute to it. So we need to all work together and try to reduce it.
  • mayzie elizondo mayzie elizondo Oct. 24, 2013
    Global warming is not all our fault. But we can not sit around and just say that we can not be blamed about this. We are the only things who can fix this and that is what we need to do. There is only one Earth and we can not let nature take this course into our own hands. We can not let this Earth be destroyed because we were too lazy to do anything about it. We need to stand up for our world and do every single thing we possibly can do to help save it, and not just sit around saying that we have not contributed to global warming.

personally i don`t care about nature. i don`t believe in global warming. i believe in a much simpler explanation. that the sun is hotter then it has been before. i shower 3 times a day before school ,in school ,after cycling ride. yesterday i thrue away a full plate of chicken, because i did not feel like eating. i take the buss every day to school, i guess thats god?
i don`t feel bad when i drive my car or throw away my food. i fly all the time, to spain.
