According to the article “Climate change could raise food insecurity risk”, the extreme weather changes may have a big impact on the food storages in many countries. Specially the underdeveloped countries. The scientist had argued that with a change of 2°C higher, some places will not be able to provide the same amount and species. The study looked at 122 developing and least-developed countries, mostly in Asia, Africa and South America.

Warmer weather in South-central Alaska has been increasing the intensity of snowfall annually. In fact, data reveals that the quantity of snowfall has risen for more than 117% for the last 150 years in winter and increased by 49% during summer. On top of that, the state is among the ones experiencing the most of climate changes, having their average temperature increased by 2-3 degrees in the last half-century. Indeed, warmer weather gives us warmer air, which can contain more moisture than cold air.

In the article “The Big Thaw” by Daniel Glick, he reports that in the Glacier National Park in 1910 there were approximately 150 glaciers and now the amount has significantly decreased to less than 30 glaciers. And predicts that within 30 years they will all melt. Scientists have proof that the earth has rapidly been getting warmer, and the cause behind that would be human activity. The burning of fossil fuel and the growth of greenhouse gases in the atmosphere have affected the temperature of the earth.

In the article “Climate Change Cause and Effect” by Joseph F. Doyle explains what humans that causes so many consequences. During 1950, the annual amount of carbon dioxide that was released in the air was around 9.2 billion tons. Nowadays, humans use 40.8 billion tons of carbon dioxide per year. In between Christmas 2017 and January 8, 2018, there was almost a new record made when it came to the amount of snowfall in North America. Other natural disasters such as strong hurricanes, wildfires, drought, hail, tornadoes and flooding have caused the U.S.

In the article “State of the science: Beyond the worst case climate change scenario” by the scientific American, the many risks of climate change are covered. The risks presented include warming temperatures, heat waves, heavy rains, droughts, stronger storms, and more. The article says all these factors will be affected due to the continuous increase of the global temperature. According to them, warming temperatures can be bring positive outcomes such as that agricultural yield will increase in colder areas and negative outcomes such as increased insect outbreaks.

The article "Warm water rapidly melting Antarctica from below due to climate change"  by the science correspondent Josh Gabsatiss, explains how climate change creates tremendous warm underwater that melts Antarctica's ice sheets, resulting in a rise of sea level which is estimated to highly threaten humankind due to possible natural disasters. It is also crucial to find the quantity of melted water expected to increase in order to be able to map the retreat of grounding lines, since the ice shelves connected to the bedrock underneath may collapse.

The article “Effects of Global Warming” by Alina Bradford and Stephanie Pappas inform us about the different effects that climate change has on our planet. According to the article, the main cause of the heating of the Earth surface, atmosphere and ocean is human activity especially the burning of fossils fuels. Indeed, the article claims that more than  197 international scientific organizations affirm that global warming has been caused by human activity.

Climate change is a very serious issue today, and it is talked about quite a lot.  A major cause for climate change is the release of greenhouse gas emissions.  Although the world is aware of the main cause (greenhouse gas emissions), there are specific reasons that countries do not always do everything in their power to stop/diminish greenhouse gas emissions.  In “Climate Change Demands We Change.  Why Aren’t We?

In the text Climate Change Is Suffocating Large Parts of the Ocean, a billfish expert name Eric Prince notice that there was something wrong with the Blue Marlin. He discovered that the one from the United States dive half-mile to chase while the same species in Guatemala and Costa Rice stay on the surface. He discovered that The billfish are actually trying to avoid suffocating. It is a known fact that hot water is lower in oxygen and climate change is making the water hotter way much more faster in some locations.

The article ‟How Climate Change Could Affect Your Health” written by Sylvie Tremblay suggests that climate change is changing our health.  One of the most direct risks of climate change is that humans have greater chance of developing heat-related illness. Rising temperatures mean more intense heat waves that strongly increase risks of heat-related illness. In fact, there are two risk factors for heat illness that American may be particularly at risk: high rates of cardiovascular disease and obesity.

In the article “Sask. Auditor says climate plan is encouraging, but still more work to do” David Baxter discusses a few environmental and climate change related issues that provincial and federal governments encounter. Canada’s commissioner of the Environment and Sustainable Development released a climate change report that most of the provinces or territories failed to meet a certain standard regarding climate change. Although many of the provinces have had plans for climate change however they did not have important details like timelines. Some provinces had no plan at all.

In her article “Climate Scientists Debate a Flaw in the Paris Climate Agreement”, Dana Nuccitelli reports that climate scientists remain skeptical about the Paris climate agreement to limit global warming to 1.5°C above pre-industrial temperatures. The 1.5°C target was initially measured by Richard Millar from the University of Exeter who used the the Hadley Centre global surface temperature dataset called HadCRUT4.

The article “Climate change ‘impacts women more than men’ by Mary Halton has for purpose to demonstrate how consequences due to global climate change can differ depending on gender. The dominant cause is simply justified as women are the principal caregivers, leading their immune system to be more vulnerable when major changes occur on our ecosystem. The article asserts that 80% of the people affected by climate change are women, not to say that in regions of Africa where there is native groups, women are more at risk as they have a valuable roles within the society.

Reading this article, I realized a lot of things I did not knew before. When it says that in 2048, overfishing will create extinction I was shook. This is in less than 50 years that means that were going to face serious economical consequences very soon. Aquaculture is a new topic that I learned from this article and this is why I found it even more interesting. I had heard about aquaculture but I never realized it could be a great solution in South China for example. But I don’t think that it means we should strop caring about the ocean. It is sad to realize how much we use our resources badly and we don’t seem to understand how important the ocean is. This article is important because even if for now it concerned Asia, it will eventually concern more people around the world because the extinction of some species will have negative impacts on everyone.

This article was really good and pertinent and I totally agree with the fact that this issue should be taken seriously worldwide before it is too late and we don't even realize it.

I decided to choose this topic due to my interest in what is the natural ecosystem change. I find it interesting to find the different ways that humans are affected through natural disasters and how they are caused.
As the writter wrote, I would have to partialy agree with them. I believe that there could be many different ways we can slow down these natural disasters or could stop rather than not being any. I do not think that it is immossible, but it is hard and is nearly immpossible unless we as humans being to contribute to the environment help stop pollution o make our ecosystem better, which may reduce the amount of natural disasters that are caused. I could see as to why you believe that their is little to no solutions due to them being "natural," but in my defence I would have to say with help of the rest of the world it could possibly reduce the amount of natural disaster and/or stop them.

I chose to answer this summary because I think it is important to focus on the causes of the issues surrounding the ocean and fisheries in order to stop them rather than trying to find solution to fix the problems. The article of World Wildlife Fund For Nature (WWF) enumerates these problems. Adding to the problems that the summary cited, the WWF article explains other causes. First, there is none or almost none regulation for fishing, when there is regulation, it is not enforced. Also, the lack of information from the fisheries, the too less no-fishing zones and the government and other fisheries does not follow the scientific recommendation is affecting negatively the ocean ecosystems.

I chose to comment on your post because I find this problem to be very scary as well as threatening many of the ocean species we still have today. I totally agree with you, that overfishing needs to be dealt with.However if companies or fisheries continue to overfish without any consequences (ex: monetary fine) then they will continue to do it. Perhaps if we could increase the security of highly dense fish populated ares, it could reduce the amount of unnecessary fish being caught. However I am hopeful, because there are people trying to fix this. According to the article "Senate Commerce, Science and Transportation Subcommittee on Oceans, Atmosphere, Fisheries, and Coast Guard Hearing: [2]" states that "The South Atlantic Council has identified five areas we propose be addressed in the current reauthorization: 1) Flexibility in ending Overfishing. 2) Flexibility in Rebuilding Overfished Stocks. 3) Define Overfishing on the Basis of the Recruitment Overfishing Level and not MSY. 4) Restrictions on Applying Harvest Moratoriums. 5) Maximum Sustainable Yield (MSY) Specification for Stock Complexes.". In my opinion, this isn't the best plan, however it is a start, and we should consider that a milestone.I hope this issue can e resolved sooner, rather than later, or before its too late.

I chose to comment on this summary because climate change is a huge issue that we need to address more. I totally agree that human activity is the main source of global warming and most people only believe it is due to gases released by machineries, cars, factories. ect but most of it comes from the food factory, especially cattle. I believe it is good to be aware of the causes of climate change which is what was mentioned in this summary. Climate change is affecting all of us and we need to take action now to avoid the problem from getting any bigger. Although it is impossible to go back and fix what damage has already been done, we can clearly fix the issues that could cause more damage in the future. If we educate people on the main issues that cause climate change, more and more people will be aware on how they can help and we could have hope for a better world for future generations.
