During the year, students in my classes will be able to comment on and contribute to discussions about things we are learning about.
It will be a check of their understanding and ability to express these thoughts in a logical and orderly manner.

Why do you think there is still some debate about whether climate change is natural or caused by human activity? Is it something about evidence or the way it is presented or ....
I think there is still debate on this matter because there are natural patterns of climate change, and some people believe that Earth is experiencing another one of those cycles. For example, the amount of energy reaching the Earth's surface from the Sun has eleven year cycles, and the data fluctuates. In addition to that, the global surface temperature also had extreme ups and downs in the past 3 decades. However, there is also evidence for the belief that global warming is man-made, like the general trend of the global surface temperature increasing. The amount of evidence on both sides are similar and almost equal, so people are unable to come to an agreement. ~Miranda Jiang
A good response, thanks Miranda. I sort of wonder how more than 7 billion of us can not have some form of impact on the Earth? The Biosphere, Atmosphere and hydrosphere are all part of a closed systems and that has an impact on them. Your thoughts?
I belive that there is still debate on this topic because in the graphs and data drawn from the last 100 years+ there has been fluctuation in the data and also a fluctuation in temperature, this is also due to the fact that every 11 years the sun temperature fluctuate and varies more drastically. Some people might see this information and believe that the earth is going through another cycle and that this is natural, even though the information shows constant fluctuation in the last 3 decades the carbon dioxide has constantly gone up and gone over 300 parts carbon dioxide, showing a constant upward trend.
One reason why people debate about this topic is because there is evidence that contradicts the belief of human activity causing climate change. According to past records, carbon dioxide levels have often been around ten times as high as they are today, and notable climate changes have repeatedly occurred during various times in history. Additionally, sea level rates have been steadily rising since 10,000 years ago, during a time preceding industrial activity: the last ice age. Thus, many people are wary of the claim that climate change is caused by human activity. -Allyson
The reason why people are still having the same old debate about climate change is because there is an argue on human causing climate change. According to the datas, global temperature has increased strongly while the sun's energy has been following it's natural 11 year cycle of ups and downs. The rise of the carbon dioxide level is impressive due to the human activities, but as the article says, there is no scientific proof that the warming is caused by the rise of greenhouse gases from human's activities.
Regardless of whether climate change is caused by humans or nature, it is important to address that it is something that exists and no matter how the facts are presented, a factor of it must be caused by humans. Although we as humans cannot change the role of nature in climate change and there is sufficient evidence to support the fact that nature is in fact contributing to climate change, there is a lot that humans can do to reduce the burden of it, as well as the fact that it affects us. Although scientists can argue that climate change is occurring at a steady pace, it also means that it will slowly go uphill from that which in any case is a bad thing, therefore if humans have any way to reduce a lot of their contribution in it, it would be beneficial to all of us.
I believe the reason why climate change is still being debated upon us is due to the lack of strong and clear evidence on the situation. Although several graphs and forms of data clearly show a rise in temperature and CO2 levels throughout the recent years, this same data has been seen in the past as well. This is not the first time earth’s temperature has risen to high levels, causing many people to actually question whether climate change is actually caused by human activity. But I feel as though the reason causing the most uncertainty is probably the fact that climate change is caused by both reasons. Scientific evidence has still yet to prove whichever of these reasons are the actual cause of climate change, therefore continuing this debate whether it is natural or caused by human activity.
I believe the reason why climate change is still such a controversial topic in the world is because there aren't any solid and 100% accurate evidence regarding climate change. Also, a lot of humans might perceive our current stage as another natural cycle in the environment, as a lot of climate change related issues have been a problem in the world and this might just be another one of those cycles. The graphs, and data gathered showing the rise in temperature does display a drastic climate change, but due to the fact we've experienced something like this before, some people might not believe this is a human caused problem but instead a environment caused one. On the other hand, people might find the cause of climate change to be the releasement of man made fossil fuels and other various products causing pollution. Both could be possible reasons of global warming, and this is why we still have debates on global warming as their isn't convincing enough evidence on both sides for people to sway onto one side. -adrian sun
The reason as to why we are having the same debate about climate change is because over the past 20 years, the trends regarding the average temperatures have been fluctuating between cold and hot temperatures but at the same time the data shows that in 2016 the average concentration of C02 reached an all-time high of 403.3 ppm. This does not mean earth is nearing its own destruction- in the arctic about 3.6 million years ago there was a period called the middle Pliocene where the average C02 concentration varied from 380-450ppm. The arctic was much warmer then, temperatures averaging 60 degrees fahrenheit (15 degrees celsius). Another argument would be that the sun is following a cycle of temperatures rising and falling every eleven years regarding how much energy from the sun reaches the earth. Some people that think global warming is manmade also have a few reasons to back them up - The surface temperatures of Earth have been following a steady trend upwards, and that temperature fluctuations have happened countless times in the past. Either way, both sides of the argument have fair and clear points (although they both like to cherry-pick data that fits their point of view) and that is why there is no clear answer whether it was caused by humans or simply a natural phenomenon.
Climate change has been caused by humans because humans decided to burn things like, coal, oil, gases and also decided to cut down trees, giving the atmosphere too much carbon.
I believe that there is still a debate because the temperature keeps changing letting some people believe that maybe there is some sort scientific reason and that there is a pattern rather than it is all people, people say it is not them because they do not want to believe that it is them.
Climate change is a common topic of controversial debate. While many have been convinced of this global concern, many still think of global warming as a fable. While the statistics are undeniably pointing towards there being global debate, some of the older generations are saying that this is a problem of the future and have just ignored it. However it would be highly beneficial if people were informed about this issue and began acting upon it.
I think this debate about climate change does not have a correct or better answer because there is no proper solution to solve this problem. Some people can argue that “man made carbon dioxide emissions throughout history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth”, but then the other people can argue back that “since the industrial age began, human emissions are far higher than volcanic emissions”. Like the example above, both sides have scientific and logical evidence to support their reasoning, leading to a very controversial debate.
The reason climate change is still being debated about is that we are unable to physically see its effects. Scientists can throw all their solid, true evidence at us, but there will always be people who think that it is false. They think that the problem doesn't exist and that is natural, hence the inaction. As for the rest of us, we say that we believe in climate change. We say that it exists. We do our best to research it and find out more about it. But at the end of the day, what do we do about it? Nothing! We sit there and think, "It's a job for someone else." Or, "We can always deal with it later. We have a lot of time." And then we go on and continue our fossil-fuel heavy lifestyle. This is the real problem. We don't feel obliged to do something about a threat until we notice its effects. And climate change is a threat that we may never see properly until it becomes too dangerous to stop. We aren't doing anything about it now and we probably never will.
Although there are a lot of research supporting man-made climate change, there are still a lot of unresolved issues regarding the climate change. The climate is constantly changing, even before humans ever existed. That is why some people still don't believe climate change is caused by human activities.

ReplyDeleteI think the levels are now well above 400 ppm (parts per million) and I wonder when it was last that high?

ReplyDeleteJust wondering if the rise of fall of Earth temperatures mirrors the 11 year sun cycle?
