But before we get into that, let’s understand the main contributors to sea level rise: Let’s take a closer look at global sea levels. Alternately, print hard copies of the graphs for students to mark up and estimate using their graph-reading skills. Highlights Reviews the early Holocene sea level rise of 11650–7000 cal. The book combines environmental studies and environmental humanities, geography and cartography, creative nonfiction and poetry to share Indigenous environmental beliefs, sea-level rise impacts and the … Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. 0000003473 00000 n All three contributors to sea level rise can be attributed to the warming of the Earth system. The questions involved in this activity refer to interactive online graphs. There are, of course, many factors that could lead to sea level changes. %PDF-1.4 %���� KM�ƺD��y� H�&��pe�>.\Zك��,�Ͼ������D{CL6�(�0J�z6�pa(3x�Pa�/C\2�㊣�7��y����_~7EVo=������|ݽL��8�Y���diFq�(��rM�_�#��"�R0�MN�b���*�Ir�z3���G1�K��;_���f�~f��R�_�������]���t��S���p��*�q��%��]������*cR�P���QO��L�{\�[(��Y��3[��v���ү!  Carbon-Climate Feedbacks The oceans then absorb the majority of this heat. A semi-empirical relation is presented that connects global sea-level rise to global mean surface temperature. The South Pacific island nation of Kiribati saw a 2.6 millimeter rise in sea level between 1992 and 2010. Because of the PDO, right now the Eastern Pacific has higher sea levels than usual, while the Western Pacific has lower sea levels than usual. {j������:܃oɏ��E�3T]�@����cP�7����+ ��0V�f��k�x*�?�C��"��:�m筋�`ΊyS8�:�6M� ����:tY�P��` *7X H���K��0����Y��� �Jս]t���8ĕy�6����6�#W�bap�|3s^ی���L�����D%�wc&i8�'RBQ1�80Ajp:�d���)^x�b��$B��!��U���R�@{���0��m��r��I{0�v`.�:�7c��`��k�%c5�E�r�Kv�r���K‚o�0�`�x�AAoUgPrr������Nj�S�$������;��RR�'���嘧V�^��u��'�z�ɡ���RQ��RQ��K4�I>���E� �;}�>���g�C�����F��� >z �탙�بst�"��U`�4���k49 w��d�Sv?4�H��S�ށ��b[׳*8��A{ӏ�ɯ�ΰN��y����cIx�-,��MJ����EY���g�;��NM�PYc���5]��R�;�TƠ?e�֟�L��C��p,H��m�v���V����h��[�%)��3�ki���C�+7`�?l������Э���>�d�Ľ���q/�$��C� �O� {�2�?�2ү1����@Aۂ�Q�ˋ��fF���[Dе?�����E64!4J��ڣ ���u��aqlk�u+���^���î��b=�). Data from these ocean altimeters is integrated to refine and calibrate measurements. This lesson is inspired by a citizen science project called the King Tides Project, which was started to raise awareness about the potential impacts of sea-level rise. ��n����6Ԃc�j�$�Y�y����&��ҟ�.%������A�R���zA��TL*�Q�K��!�c���tT�$�jc�W&�1&�p@qj9������0)��#��P�J�1�:K�5 0000000016 00000 n It doesn’t mean that seas are higher by the same amount everywhere. Math Projects for 2nd Grade Gifted Students. The most sophisticated approach is to find slope of the line of best fit. What is the approximate rate of sea level rise between January 1993 and present? 0000004218 00000 n Students can use what they learn in this lesson to then contribute to the King Tides Project as an extension activity or on their own. A retractable barrier designed to protect Venice from sea level rise and storm surges is set to be operational next year. Recent projects include analysis of sea level rise impacts on historical timescales (analysis of sediment cores, maps, and tree rings), modern timescales (flooding experiments), and especially the development of numerical models to make future predictions. These are all great questions! Between 1900 and 2016, the sea level rose by 16–21 cm (6.3–8.3 in) on average.

Science Fair Project Idea On December 26, 2004, a magnitude 9.2 megathrust earthquake off the west coast of Sumatra, Indonesia unleashed a powerful tsunami that hit the coasts of 14 countries and caused the loss of over 200,000 lives. 0000011267 00000 n The study, published in PLOS ONE, Jan. 22, is the first to use machine learning to project migration patterns resulting from sea-level rise. After a $14-Billion Upgrade, New Orleans' Levees Are Sinking. endstream endobj 39 0 obj<> endobj 40 0 obj<>stream Can you offer an explanation for the correlation or lack thereof? Sea level rise is the increasing of the average global sea level. Accordingly, the U.S. Interagency Sea Level Rise Task Force (henceforth referred to as “Interagency”) 71 has revised the GMSL rise scenarios for the United States and now provides six scenarios that can be used for assessment and risk-framing purposes (Figure 12.4a; Table 12.1). Make sure the ice cubes float and do not touch the bottom of the container. Project partners include Louisiana State University, the University of Central Florida, the University of South Carolina, Texas A&M University–Corpus Christi, and NOAA’s Northern Gulf of Mexico Sentinel Site Cooperative. Even NASA is concerned about some of its facilities that are located in low-lying areas. Citizen Science Projects and Sea-level Rise. Today, global mean sea levels are steadily rising and are expected to keep rising until at least 2100. In fact, in some areas, such as the west coast of the US, sea level has actually dropped slightly … for now. The rate of global sea-level rise was 2.5 times faster from 2006 to 2016 than it was for nearly all of the 20th century. Burning fossil fuels is one of the causes of global warming because it releases carbon dioxide and other heat-trapping gasses into the atmosphere. In this activity, students use models to demonstrate the differing impacts that melting land ice and sea ice may have on sea level rise. 0000001242 00000 n This activity is related to a Teachable Moment from Sept. 3, 2015. Science Projects for 7 Year Olds. We carried out a Foresight project to consider the role that science and technology can play in understanding and providing solutions to the long-term issues affecting the sea. However, if Internet access is not available for students, consider projecting one set of graphs for the whole class to consult and appointing one student to mouse over appropriate points. Research project: Coastal resilience in the face of sea-level rise ... To date, much concentration on Shoreline Management Plans has been based on the domains of physical science and engineering, with less consideration of the people who affected. This is because it can be affected by ocean currents and natural cycles, such as the Pacific Decadal Oscillation, or PDO, a 20- to 30-year cyclical fluctuation in the Pacific Ocean’s surface temperature. It is proposed that, for time scales relevant to anthropogenic warming, the rate of sea-level rise is roughly proportional to the magnitude of warming above the temperatures of the pre–Industrial Age. If we can control our contributions to the rise in greenhouse gases in Earth’s atmosphere, we can perhaps level out the warming of the Earth system and eventually stabilize our sea levels. 0000014545 00000 n 0000021619 00000 n endstream endobj 26 0 obj<> endobj 27 0 obj<> endobj 28 0 obj<>/ColorSpace<>/Font<>/ProcSet[/PDF/Text/ImageC]/ExtGState<>>> endobj 29 0 obj<> endobj 30 0 obj<> endobj 31 0 obj<> endobj 32 0 obj[/ICCBased 48 0 R] endobj 33 0 obj<> endobj 34 0 obj<> endobj 35 0 obj<> endobj 36 0 obj<> endobj 37 0 obj<>stream “Sea level rise” – we hear that phrase, but what does it mean, really? Sciencing. In science, models are often representations of an object or process that enable predictions to be developed and tested.
