Discussions Discussion Climate Change Effects on the Ocean
Skyler W-US, Feb. 27, 2014

Hey, I’m Skyler, and I just want to start off by saying the going to the beach to enjoy the ocean is my favorite vacation I could ever take. I try and go every summer, or any time I can at all. It makes me sad to know that our oceans are beginning to be polluted and that our carbon dioxide output is ruining the oceans. I want to do everything that I can to help lower my emission level.

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.

Lily P-US, Feb. 25, 2014

Hey I’m Lily, and I grew up on an Island off the coast of Florida, so the ocean is very near and dear to my heart, a part of me in a way. I think after I discovered my affect on the ocean, and the detrimental consequences the ocean is facing due to human emissions I was even further inspired to do whatever I can to reduce my footprint and live more sustainably. Travel was the highest emission category for me, and I hope to reduce this in the future by moving back to a place (like the Island I lived on) where things are in walking/biking distance. I unfortunately have no way currently to travel besides car because of my location. But the realization of the danger the ocean, (and rest of the planet for that matter) is in, it has become even more important to me to relocate to somewhere that I can reduce my travel emissions and live way more sustainably.

    Lily, I too grew up on an Island. As a kid growing up in Hawaii I was outside 24 hours of the day. You don't notice the affect that we have on the environment until you are actually outside in nature's playground and see that we do. It was not an uncommon thing to see trash in the ocean, but in reality it should be uncommon. We as a generation need to step up and educate people about our affect as humans on this planet.
  • Lily P-US Lily P-US Feb. 28, 2014
    Hello Heidi! It truly is heartbreaking when people have no regard and just pollute our oceans. What people don't realize is, even when they litter on the side of the road or something, that will find its way into our water systems. I totally agree we need to educate people, because it is such and important issue.

Discussions Discussion Our Acidic Oceans
Abby Lieblich, Oct. 25, 2013

Hi everyone! I’ve become very conscious of the oceans and what we’re doing to harm them. Carbon dioxide released by humans causes oceans to grow more acidic. This affects marine creatures and their ecosystems. As pH levels rise, the more these things are not performing as well as if the ocean pH was more basic.
This carbon dioxide harms plankton in the ocean. These plankton are important because they produce oxygen. This is dramatically lowering the amounts of oxygen.
As the greenhouse gas effect causes ice caps to melt, more water is filling the ocean. Warm water is bigger than cool water, and global warming is causing it to become warmer. The ocean level has risen dramatically by 4-8 inches.
We have to help our oceans!

    Hi Abby
    Yeah I hate how we humans are doing a big harm on the ocean and just the planet. We need to reduce this as much as we can, because not only is the water filling the ocean but animals that live where the ice is melting are getting harmed too.

Discussions Discussion Climate Change Effects on the Ocean
Gabriel Sibol Pineda, Oct. 25, 2013

Hey, my name is Gabe and I’m from California, USA. First of all, I just want to say that I was shocked when I found out what my carbon footprint was and how it affected the environment, i.e. the ocean. I was shocked to find out that the worst factor in my carbon footprint was the the food consumed by my family. Even if we ate organic meals, the calculator still said that this was the worst aspect of my footprint.
What upsets me is the fact that small things like these negatively reflect on our environment. My total footprint result was below the average from where I live in. Knowing this, I’m guessing that the ocean surrounding my home area is in bad shape.
People tend to forget that everything e do affects our surroundings. It’s because of this that our oceans are all turning acidic. With a fall on the pH scale, the ocean is becoming less suitable for calcifying organisms to live in. With a projected pH reading of 7.96 by 2050, organisms such as corals and urchin larvae are all going to eventually die out. The bodies are already getting weaker by coming into contact with carbonic acid produced from the harmful carbon dioxide in our atmosphere. We can all be directly blamed for this.
Aside from that, it is proven that these organisms’ bodies are getting smaller and less dense. The lower pH readings in the ocean mean it’s getting more acidic. The properties of acid are causing the ocean’s calcifying organisms to wither and die.
From working with my Biology class in my school, I realized that everything we do affects our carbon footprint while our footprint itself affects the lives of other organisms in the ecosystems around us, in including those in the ocean.

    I know how you feel Iv'e had the same experience when I realized how my footprint was I started to change in my habits.
  • Keri G Keri G Feb. 10, 2014
    Hi Robert, I was equally surprised when my results came back and the highest part of my carbon footprint was the food that my family and I were eating. Opps, better work on that!

Discussions Discussion Is climate change real? Is it mostly human …
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.

Discussions Discussion Climate Change Effects on the Ocean
Kelsi Schacht, Oct. 24, 2013

When people think of climate change, marine life isn’t usually the first thing that comes to mind. Since 1960, the level of CO2 in the our atmosphere has increased 75 ppm. The more concentrated the CO2 is, the more it will dissolve into oceans and lower the pH of the ocean water. Increasing the acidification affects organism’s ability to form calcium and can lead to weaker shells and slower growth.
If we continue to produce these large amounts of CO2, there will be horrible consequences. Even a slight drop in pH can have measurable effects on marine life. For example, in one experiment, sea urchin larva was placed in pH 7.7 and 8.1. The more acidic solution produced larva with shorter arms, which is what they use to eat. The survival rate would go down and then the organisms that relied on the urchins as their food supply would be effected as well.
The average ocean pH could be 7.96 in the year 2050 unless the carbon levels emitted into the air drop. Basically, if we continue to idly stand by and watch this happen, there will for sure be dire consequences in not just our oceans, but everywhere.

    Hi my name is Bergrós and I´m from Iceland. I was interrested in what you said about the consequences in oceans everywhere as the warmer water around the shores of my country continues to have heat fluctuations. From the year 1998 to 2008 the tempreture and salt levels of our ocean has most often been way above average. If it keeps having theese fluctuations it will most likely have an effect on the aquaculture around my country which is our most profitable industry.

Andrew W, Oct. 23, 2013

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.

Ocean acidification is a really serious problem. Right now our pH of the oceans is 8.1 but since the pH scale is logarithmic, which means a drop of 0.1 is a 30% increase in acidification. Also, lots of marine organisms need positive calcium ions to form their shells, and acids in the the will neutralize them, therefor making them grow slower. this would be a major problem since if the organisms at the bottom of the food web decreased, the ones at the top would starve and the whole ecosystem would crash, affecting us as well. So, if we want to have a healthy earth, ecosystem, and eat seafood, we should find a way to lower carbon emissions.

    Some ways we can lower carbon emissions are: eating less meat, use solar/wind electricity, use energy and water efficient appliances, and take public transportation when you can.
  • kyle cafarelli kyle cafarelli Oct. 24, 2013
    I agree with nikita, people (myself included) need to start thinking about what he do when it comes to our carbon emisions. We should all really carpool or take public transportation as much as possible. I do all of these and even bike as much as possible. I was shocked when i found out how bad the worlds carbon emissions are.
  • chase junnila chase junnila Oct. 28, 2013
    I agree with you. Ocean acidification is indeed a very serious problem. It also affects coral, which throws off the whole oceanic ecosystem. It's hard for a lot of animals to adapt to the high acidity in the water.
