Blog Post 5: Due FRIDAY January 16th

Based on the question, passage, and figures that you read and analyzed from the booklet: Climate Change: Evidence, Impacts, and Choices, create the following blog post:

1. The QUESTION that you chose to read about

3. Relate the MAIN POINT from that section of the text. What is the most important thing we need to understand regarding the question you chose?

2. A brief summary of the FIGURE connected to that question. (What is this figure displaying? Why is it significant?)

  1. 1.What are the choices for preparing for the impacts of climate change?
    2.The main point of this section is the idea of preparing an adaption plan to help us in the long run for when/if climate change occurs. If we are better prepared ahead of time, then we will know what to do when the time comes.
    3. The figure is displaying possible adaption actions for one expected outcome which is sea-level rising. Some of theses actions are: site and design all future public work projects to take sea level rise in account, retrofit/protect public infrastructure (storm water/waste water systems, energy facilities, roads, causeways, ports, bridges, etc.), and encourage alternatives to shoreline “armoring” through “living shorelines” The figure also explains the impacts that sea-level rising will have for example, it will flood low-lying land, saltwater will intrude into coastal aquifers and rivers, and there will be changes in navigational conditions. Climate change happening around the world will also affect us here in the United States so it’s important to get other countries to do the same.

  2. 1. How do we know that earth has warmed?
    2. The main Idea of this text is that Earth’s average surface temperatures has increased by more than 0.8 C over the past 100 years.
    3. This article talks about how temperatures are increasing on earth.Although it might not be alot still effects the earth. By melting glaciers and rising sea level.And it is shown in figure one how temperatures have rise through the years.

  3. 1. How do scientists project future climate change?
    2. The main point of this section is how scientists collect data from multiple factors, like greenhouse gases, to be able to predict future climate change. Collecting data from past years to today and analyzing the changes through out the year and predict, based on their data, future changes.
    3. This section of the article talks about how scientist consider multiple factors that would have some kind of connection or impact in climate change. Such as how much energy people use or will use and considering any national and international policies might implied to control emissions and what new technologies might become available. And how scientist use that information to predict more accurate changes in the future.

  4. 1. How will ecosystems be affected?
    2. The most important information to take from this reading was the fact that the phytoplankton will soon be going into extinction. The reason for this is because the higher the ocean surface temperatures the more distant the warmer surface waters and cooler deep waters will be. This separates the marine life from the necessary nutrients they need. If phytoplankton doesn’t get enough nutrient they will slowly decrease meaning there will be a problem in the food chain.
    3. In figure 27, it illustrates the Change in Primary Production. There is a majority of colors that consist of blues and yellows which ranges from -12 to 3 pp.

  5. 1. How much are human activities heating earth?
    2nd. Main idea of this is how human activities are influencing earth climate to change.
    3rd.all human activity cause Ice to melt due to bad co2 as shown on page 10 it causes temp to decrease

  6. 1. How do we know that greenhouse gasses lead to warming?
    2. The main idea of this section is to see if certain gases have an effect on the atmosphere & to see if these factors are really the cause of global warming. This section talks about how green house gases are absorbed and then radiated upward into the atmosphere from the Earth’s surface. This then leads to gases being trapped in the atmosphere & causing a gas blanket, which traps heat.
    3. The image shows natural warning and amplified warning. The sun heats the ocean and land & explains the process of gases being absorbed.

  7. 1. How do we know that greenhouse gases lead to warming?
    3. The main point of this section is how greenhouse gases are natural and part of the carbon cycle. Without out greenhouse gases, theyre wouldnt be life on earth. However, we, as humans, are pushing it to be more “concentrated” I guess, leading to temperature rise.
    2. The significance of the figure is a visual and better understanding of what is happening and how it is happening. How it works is that the Sun’s energy hits earth and some is reflected back to space. The one that’s absorbed is absorbed by land and oceans, which is then radiated upwards from earth’s surface. This is because of how greenhouse gases are stuck in the atmosphere and decreasing them would result in temperature to lower as increasing would cause it to rise.

  8. *without greenhouse gases, there wouldn’t be life on earth

    1. How much are human activities heating Earth
    3. The main point of this section is about the ways that human activities are making change toward our Earth and how it is happening along with what factors lead to this occurring change
    2.On page 10 there is a figure that basically explains the cycle of this change. This figure is significant for the reason being that it shows a cycle that goes from temperature rise which leads to arctic sea ice melting and as that takes place then the reflective disappears and darker ocean water absorbs more heat and this whole process is a repetitive cycle.

  10. 1. Effects of Sea level Rising
    2. The main idea of this section is the aftermath of Sea level rise. Sea level rise has drastic impacts – primarily on coastal regions. Populations in coastal regions are predicted to have to relocate and be displaced due to inundation and natural storms. Sea level rise is directly linked to GCC and the greenhouse effect, thus it is an anthropoid-based problem and cause.
    3. Figure 25 shows data of sea level change from tide gauge and satellite imagery. This is important because it details the idea of sea level rise’s time of change increasing; as years go by, sea level rise increases more rapidly. Thus, it is difficult to accurately make predictions on when we will see the most impact of SLR.

  11. 1.What would happen if all the crops are gone?
    2.The main idea about this article was about how the climate change is stress out and how is getting warmer and the crops are dying
    3.Each degree that passes the u.s drop by 5-15%

  12. 1.What can we do to prepare for impacts in climate change?

    2the main idea is to help us understand on how we can prepare for incoming climate changes and how it’s better to plan ahead.
    3climate change can be bad is it happens to an extreme this article give us a better understating on climate change.and since this I happening around the world we need to get more counties to know what to do aswell.

  13. 1. How do we know that earth has warmed?
    2. The main important thing I believe is important is that the earth’s average temperature has increased by 0.8 c over the past 100 years.
    3. The text is about how a slight change in temperature still effects the earth a lot. It also talks about how melting glaciers is the cause of rising sea levels.
