If climate changes naturally, then why should we be concerned about the climate change taking place today? While they can often be predicted, the loss of life and property take an emotional and economic toll on the community impacted. The primary components of sea-level rise are thermal expansion and the melting of small (continental) glaciers. The jagged, solid lines show the annual data, while the linear dashed lines show the long-term trend over the 1948–2016 period for both global and Canadian data. What would make these events newsworthy? This is why the presence of these gases is crucial for life on Earth. In groups, have students research Hurricane Harvey, and use the worksheet to analyze the effect climate change had on the flooding from the storm. Code of Ethics. The change in global average temperature (in black) is calculated from Hadley Centre’s sea surface temperature records and the Climate Research Unit’s land surface air temperature records version 4 (HadCRUTv4) dataset, while the change in Canadian average temperatures (in blue) is calculated from the Canadian Gridded Temperature and Precipitation Anomalies (CANGRD) dataset. Climate change may threaten people's jobs and livelihoods. It means changing our activities and decisions so that we reduce the negative impacts of climate change and become more resilient. Without drastic changes, it's expected that there will be devastating changes in biodiversity and ecosystems. What causes climate change? Second, while land use change is an important driver of climate change, a changing climate can lead to changes in land use and land cover. Climate change, heavy rains, and increased temperatures are linked with the increased transmission of vector and waterborne diseases like malaria, dengue, and diarrhea (who). Categories three to five are considered a major storm. Download here your action plan against climate change! These effects, in turn, influence the intensity and, in some cases, the frequency of extreme environmental events, such as forest fires, hurricanes, heat waves, floods, droughts, and storms. The Paris Agreement at the 2015 climate summit mentioned insurance solutions as a way to facilitate adaptation to climate change. Floods are among the most expensive and frequent natural disasters in the United States, and as the impacts of climate change are more acutely felt, floods are expected to worsen. (Answer: There are many reasons students might give, such as population growth, development into areas more at risk for natural disasters, sea-level rise, or climate change.) Tell students they are going to focus on two extreme weather-related disaster events and look for evidence that climate change played a role. Analyze how climate change affected a specific natural disaster event. At the G7 summit in Elmau in June 2015, the member states agreed to launch a climate insurance initiative (InsuResilience), highlighting the importance of financial risk transfer concepts, particularly for emerging and developing countries. If no button appears, you cannot download or save the media. The environmental hazards you face depend on where you live. Current climate change is mainly caused by human activities that release greenhouse gases to the atmosphere. © 1996 - 2020 National Geographic Society. This is caused by natural processes linking the atmosphere, ocean and land, as well as variations in heat output from the sun. Deforestation can involve conversion of forest land to farms, ranches, or urban use. tropical storm with wind speeds of at least 119 kilometers (74 miles) per hour. 'It can get hotter or wetter on average or have more concentrated rain in a short period, but then get longer dry periods. Students can take notes as they watch the remainder of the video and then craft the worksheet responses from their notes. Climate change is defined as gradual changes in all the interconnected weather elements on our planet over approximately 30 years. As extreme weather events such as cyclones and heatwaves increase in frequency and ferocity, they threaten children’s lives and destroy infrastructure critical to their well-being. You will not receive a reply. They analyze data from long-term observations of climate in the air and under water, using graphs to convince community members to sign a Climate Change Challenge Pledge of their design. Increasing greenhouse gas levels in the atmosphere makes it more effective at trapping heat, resulting in overall warming of the earth. 1145 17th Street NW This can all be contributed to climate change. Divide students into groups of two or three and distribute the Analyzing a Natural Disaster Event handout to each student. Watch a video about the 2017 California wildfires. 2013. Understand that climate change impacts the likelihood of extreme weather-related natural disaster events. However there are other changes in climate could be as important, or even so, than changes in the mean climate state. Integrated Risk Management (IRM) is an enhanced, holistic approach to increase community resilience by integrating disaster risk reduction, climate change adaptation and ecosystem management and restoration first used by the Partners for Resilience program. Environment and Climate Change Canada. Learn more about actions to reduce emissions. Importance: Why Should We Care About Climate Change? Reducing these two components of risk requires identifying and reducing the underlying drivers of risk, which are particularly related to poor economic and urban development choices and practice, degradation of the environment, poverty and inequality and climate change, which create and exacerbate conditions of hazard, exposure and vulnerability. To learn about climate change, you first must know what climate is. The Rights Holder for media is the person or group credited. Facts about the Climate Emergency The Climate Emergency we currently face requires adequate and immediate action. 2. In some societies, cultural characteristics may be the determining factor in whether people will be adversely affected by climate change or hazards. Burning fossil fuels (coal, oil, gas) and some industrial processes are the main sources of carbon dioxide. Ask students to give you examples of natural disasters, including floods, earthquakes, hurricanes, droughts, wildfires, tornadoes, landslides, volcanic eruptions, tsunamis, snowstorms, and severe thunderstorms. Climate change magnifies the existing risks and vulnerabilities associated with disasters, due to changing patterns of some hazards and due to increased population exposure and land-use changes. Ask: What does the black line represent? Environment and Climate Change Canada. The annual average economic losses from climate-related disasters are in the hundreds of billions of dollars. (Answer: These lines represent specific years.) One exception found that awareness of climate change and disaster risk was positively associated with self-efficacy, distress, risk perception, concern, responsibility, resilience, and adaptive capacity, while distress, risk perception, and concern were found to have a negative association on resilience, concluding that higher risk perception and concern may not positively influence adaptive … The costs of doing nothing against the effects of climate change in coastal areas are estimated to be higher than the annual costs of taking actions, which is estimated at around €6 billion by 2020. Addressing climate change as one of the drivers of disaster risk, while respecting the mandate of the United Nations Framework Convention on Climate Change, represents an opportunity to reduce disaster risk in a meaningful and coherent manner throughout the interrelated intergovernmental processes. Deforestation, clearance, clearcutting or clearing is the removal of a forest or stand of trees from land which is then converted to a non-forest use. Similarly, they may observe that some occurred in agricultural areas, which may have affected crops and damaged the economy. The main characteristics of climate change are increases in average global temperature (global warming); changes in cloud cover and precipitation particularly over land; melting of ice caps and glaciers and reduced snow cover; and increases in ocean temperatures and ocean Certain gases in the atmosphere trap this heat and act like the glass of a greenhouse. It also includes changes that are forecast over the next few days, for example, in temperature and rainfall. They analyze how climate change affected the 2017 California wildfires and the … In Canada, the average temperature increased by 1.7°C during the same time period, about double the global average (Figure 1). Climate-Smart Agriculture (CSA) is an approach to help the people who manage agricultural systems respond effectively to climate change. Go over the questions on the worksheet with students so they are familiar with them. The purpose of this guidance note is to explore how coherence of the post-2015 global frameworks - especially the Sustainable Development Agenda, the Sendai Framework for Disaster Risk Reduction, and the Paris Agreement on Climate Change - may be pursued in practice in Asia-Pacific countries. Warming has been even stronger in northern Canada. The Climate Emergency we currently face requires adequate and immediate action. He explains, 'Climate change is how the characteristics of the weather we experience in a certain place change. When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. Further changes are inevitable, with larger changes projected for higher emission scenarios. Many people exposed to climate related or weather-related disasters experience stress and serious mental health consequences. Ask: What do the colored and gray lines represent? All of these pose risks for agriculture, food and water supplies. has led to the greenhouse effect, resulting in climate change. Ask students: What are some factors that may explain this general trend? If you have questions about licensing content on this page, please contact firstname.lastname@example.org for more information and to obtain a license. Floods are among the most expensive and frequent natural disasters in the United States, and as the impacts of climate change are more acutely felt, floods are expected to worsen. Review the environmental conditions that make wildfires more likely. If students do not mention climate change, introduce the idea to them. Ask: Did you hear about any of these natural disasters in the news? uncontrolled fire that happens in a rural or sparsely populated area. You cannot download interactives. Continue playing the video. The most concentrated deforestation occurs in tropical rainforests. This shrinking sea ice disrupts normal ocean circulation and creates changes in climate and weather around the globe. The Agenda also identifies, in its paragraph 14, climate change as “one of the greatest challenges of our time” and worries about “its adverse impacts undermine the ability of all countries to achieve sustainable development. Pause the video and ask students to briefly explain the evidence Park Williams gives linking climate change to an increase in wildfires generally. Between 1990 and 2013, more than 1.6 million people died in internationally reported disasters, with annual deaths trending upwards. The primary components of sea-level rise are thermal expansion and the melting of small (continental) glaciers. In Canada, temperature has increased about 1.7 degrees Celsius over the 65-years from 1948 to 2013. … Students use maps and graphs to understand how the frequency of billion-dollar natural disaster events has changed over time. Ask students to make observations about the map. Governments, funders, researchers, and practitioners must act now Coastal areas are often most heavily impacted by the damaging winds, rains, and storm surges as the storm collides with or brushes land. gradual changes in all the interconnected weather elements on our planet. Dramatic and unprecedented natural disasters have had little effect on the public. Paleoclimatology—or the study of changes in climate throughout Earth’s history—uses evidence found in tree rings, ocean sediment, coral reefs, and layers of sedimentary rocks to determine that current warming is occurring roughly 10 times faster than the post-ice age warming. The importance of the climate change issue stems from the impact of changes in climate on human and natural systems. Step 3: Connect the activity to students’ personal lives by using the drop-down menu on the Billion-Dollar Disaster Event map to select your state and view events that have impacted your area. Global temperatures and sea levels are rising, and possibly contributing to larger more devastating storms. The Arctic is an incredibly important and very fragile ecosystem – and it’s warming at a much faster rate than much of the rest of the world. In the United States, the amount of greenhouse gas emissions has held steady since 1990–even though our economy and our population has grown. But, as individuals we can slow down global warming by implementing small more sustainable actions within our community. Agriculture is a major source of greenhouse gas emissions. Explain that while many factors contribute to any weather event, scientists agree that climate change in general is and will continue to lead to more extreme weather events—from droughts to flooding to hurricanes. Hurricanes are the same thing as typhoons, but usually located in the Atlantic Ocean region. Terms of Service | (Answer: The black line represents the average of all the years in the range represented on the graph.) Learn more about climate trends and projections. Climate change mitigation is about reducing greenhouse gas emissions from human activities. As a class, review the environmental conditions that lead to a hurricane.  But globally, greenhouse gases have increased since then, bringing humanity very close to the dangerous levels of global warming that were predicted. For years, scientists have known that climate change can lead to more extreme weather events. In addition to property damage, floods, on average, kill more people than tornadoes, hurricanes, or lightning strikes in the United States each year. About 31% of Earth's land surface is covered by forests. In addition to changes in climate that are caused by natural climate variability, climate change can be caused by human activity. Read or summarize the text under the heading “2017 in Context.” Make sure students understand that the number of billion-dollar events in 2017 was significant because it was higher than both the historic and recent five-year average and because of its high economic impact. The kind of climate change we are experiencing now is being caused primarily by these human factors. Step 4: Model note-taking as students view the first segment of the video. 14. The data shows the Earth is warming and it's up to us to make the changes necessary for a healthier planet. The heavy rains and increased temperatures lead to increased humidity which increases the chance of mosquito breeding and survival. Ask: What types of natural disasters are shown on the map? The audio, illustrations, photos, and videos are credited beneath the media asset, except for promotional images, which generally link to another page that contains the media credit. They analyze how climate change affected the 2017 California wildfires and the flooding from Hurricane Harvey. Text on this page is printable and can be used according to our Terms of Service. Why or why not? Depending on the type of the disaster, these consequences include post-traumatic stress disorder (PTSD), depression, and general anxiety, which often occur at the same time [Very High Confidence]. Climate change is a long-term shift in the average weather conditions of a region, such as its typical temperature, rainfall, and windiness. Increasing sea level (1,7 mm/year) changes the shape of coastlines, contributes to coastal erosion and leads to flooding and more underground salt-water intrusion. becoming a catch-all for tackling climate change impacts in a development context. The evidence for the impact of climate change and air pollution on children is firm and growing, but time is running out fast. According to the 2014 report on Climate Change Impacts, Adaptation and Vulnerability (page 8) from the United Nations Intergovernmental Panel on Climate Change, governments at various levels are also getting better at adaptation. Credit: The Select Committee on Energy Independence and Global Warming. It is one of the most pervasive and threatening crises of our time. The CSA approach pursues the triple objectives of sustainably increasing productivity and incomes, adapting to climate change and reducing greenhouse gas emissions where possible. She or he will best know the preferred format. Ask: Why might such damaging disaster events happen in these locations? Pause the video frequently to discuss and check for understanding. These events are newsworthy primarily because they resulted in great damage to property and possible loss of life.) The importance of the climate change issue stems from the impact of changes in climate on human and natural systems. Addressing climate change as one of the drivers of disaster risk, while respecting the mandate of the United Nations Framework Convention on Climate Change, represents an opportunity to reduce disaster risk in a meaningful and coherent manner throughout the interrelated intergovernmental processes. Climate change, the periodic modification of Earth’s climate caused by atmospheric changes and the atmosphere’s interactions with geologic, chemical, biological, and geographic factors. Climate change may not be responsible for the recent skyrocketing cost of natural disasters, but it is very likely that it will impact future catastrophes. Engage students in the topic by inviting them to share their knowledge of natural disasters. Privacy Notice | This is not to say that there hasn’t been progress. Discuss the differences in the role climate change played in the California wildfires and the role it played in the flooding in Hurricane Harvey. Water As these massively destructive and costly events become more frequent, scientific evidence points to climate change as a leading cause. 1.4 The resilience and adaptive capacity of all types of forests to natural disasters and the impact of climate change is significantly strengthened worldwide. From 1948 to 2016 the global average temperature increased by approximately 0.8°C. Keep track of any such linkages over the course of the year. Climate change is just one of the stressors currently impacting nature. If a media asset is downloadable, a download button appears in the corner of the media viewer. Climate change means that the range of conditions expected in many regions will change over the coming decades. As a class, determine a working definition of the term natural disaster. We are facing an existential threat and rapid prioritization of attention and action is necessary. Climate change is a direct threat to a child’s ability to survive, grow, and thrive. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. Scientists are already seeing dramatic reductions in Arctic sea ice cover, particularly in the summertime. Most important, the market doesn’t generate the public goods sometimes known as “ecosystem services”, such as nutrient cycling, soil formation, oxygen creation and a livable climate. These environmental hazards shape human activity regionally. Sadly, climate change is only one – albeit a whopper – of the countless market failures that degrade our lives. Natural disasters increasingly linked to climate change, new report warns 'This is a real world analysis of what is actually happening, rather than … The purpose of this guidance note is to explore how coherence of the post-2015 global frameworks - especially the Sustainable Development Agenda, the Sendai Framework for Disaster Risk Reduction, and the Paris Agreement on Climate Change - may be pursued in practice in Asia-Pacific countries. Learn the human impact and consequences of climate change for the environment, and our lives. This can occur when there is a large amount of rain, rapid snow or ice melt, a blast of water onto a coastline during a storm, or the failure of manmade infrastructures, such as dams or levees. The challenges posed by climate change, such as more intense storms, frequent heavy precipitation, heat waves, drought, extreme flooding, and higher sea levels could significantly alter the types and magnitudes of hazards faced by communities and the emergency management professionals serving them. Building codes in California require builders to meet standards set to minimize structural damage in an earthquake and coastal cities have building code to reinforce roofs and walls to resist a storm’s high winds. Once students have identified that trend, challenge them by asking how that could be true, since there were more events in 1989 than there were in 2014. The climate varies naturally from year to year and decade to decade. Medical costs and loss of life are not considered in the final number. Resilience is therefore a predominant concern. In 2017, scientists made connections between two weather-related natural disaster events in the United States—the California wildfires and the flooding from Hurricane Harvey. For example, rising temperatures can increase the length of growing seasons or the varieties of plants that can be grown in different areas. Disaster losses are likely to increase into the foreseeable future as a result of drivers of change, including: climate change; critical infrastructure interdependence; and shifting demographics in Canada. For information on user permissions, please read our Terms of Service. Have students look back at their list of examples. Sustainability Policy | Floods are events where water overflows onto land that is typically dry. To understand climate change, we first need to understand the difference between weather and climate. Key Finding 1: Exposure to Disasters Results in Mental Health Consequences. The impact will be heavy. Have students predict how the frequency of billion-dollar natural disaster events will change in the next one hundred years and explain their reasoning. The Canadian data are more variable than the global data. The purpose of putting culture in the centre of disaster risk reduction is not to place blame on culture, but rather to raise awareness of this important dimension of vulnerability. Project the U.S. 2017 Billion-Dollar Weather and Climate Disasters Map from NOAA’s Billion-Dollar Weather and Climate Disasters: Overview webpage. Human and natural systems are influenced by climate variability and hazards, with the negative impacts most severely felt in developing countries. Learn more about environmental hazards with this curated resource collection. If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher. (Answer: Depending on where students live, they may be familiar with any of these events, but the California wildfires and the three hurricanes were covered extensively in the national news. Sea use, invasive species, pollution and the exploitation of organisms are all factors in the threat to nature. Climate change and ecosystem degradation place new demands on disaster risk reduction approaches. The sun’s energy warms the Earth and the warmed Earth releases heat to the atmosphere. 1.4 The resilience and adaptive capacity of all types of forests to natural disasters and the impact of climate change is significantly strengthened worldwide. The greenhouse effect is a natural process, but it is being intensified by human activities that increase greenhouse gas levels in the atmosphere, especially carbon dioxide. Climate change also causes changes in European seas surface temperature, which has been up to six times greater than in the global oceans in the past 25 years. 5. Many climate change adaptation efforts aim to address the implications of potential changes in the frequency, intensity, and duration of weather and climate events that affect the risk of extreme impacts on human society.
