If not, what are the arguments for and against? In some societies, cultural characteristics may be the determining factor in whether people will be adversely affected by climate change or hazards. What is important for them to recognize is that there could be multiple factors contributing to the costliness of these events.). If climate changes naturally, then why should we be concerned about the climate change taking place today? The most concentrated deforestation occurs in tropical rainforests. This means that there will also be changes in extreme conditions. 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. 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. Project the U.S. 2017 Billion-Dollar Weather and Climate Disasters Map from NOAA’s Billion-Dollar Weather and Climate Disasters: Overview webpage. In the absence of countermeasures, climate change will affect many sectors that are directly relevant to disaster risks, including water management, food and agriculture, industry, human settlement and land use, health and even national security. Print. Environment and Climate Change Canada. In addition to property damage, floods, on average, kill more people than tornadoes, hurricanes, or lightning strikes in the United States each year. Why or why not? As we have discussed, climate change can be natural. 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. Increasing greenhouse gas levels in the atmosphere makes it more effective at trapping heat, resulting in overall warming of the earth. 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. Information, Media, and Technology Skills, Obtaining, evaluating, and communicating information, Tech Setup: 1 computer per small group, Projector, Speakers.

In 2018, more than 17.2 million people fled disasters in 125 countries and territories. Scroll down to the 1980—2017 Year-to-Date United States Billion-Dollar Disaster Event Frequency graph. The CSA approach pursues the triple objectives of sustainably increasing productivity and incomes, adapting to climate change and reducing greenhouse gas emissions where possible. The impact will be heavy. Climate change is a proven fact. 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. Governments, funders, researchers, and practitioners must act now Weather refers to the actual atmospheric conditions that are being experienced now. We are facing an existential threat and rapid prioritization of attention and action is necessary. For example, if you live in northern California you are more likely to be impacted by a wildfire, landslide, or earthquake than if you live in Charleston, South Carolina, but less likely to be hit by a hurricane. Linkages between certain extreme weather events and climate change can increasingly be made while the weather event is relatively recent, which can help to highlight the need for climate change mitigation. These environmental hazards shape human activity regionally. They analyze how climate change affected the 2017 California wildfires and the flooding from Hurricane Harvey. Point out that the costs of these disasters are calculated by considering property and infrastructure damage and business interruption. The main effects expected are as follows. Climate change adaptation is about preparing for the current and future impacts of climate change. Learn more about actions to reduce emissions. I f one uses the example of g lobal climate change and the disaster agents, e.g. Adaptation also involves taking advantage of opportunities from climate change. The kind of climate change we are experiencing now is being caused primarily by these human factors. tropical storm with wind speeds of at least 119 kilometers (74 miles) per hour. The economic value of coastal areas within 500 metre from the European seas totals between €500-1,000 billion. 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. Have students research Hurricane Harvey and analyze evidence that climate change contributed to the severity of the flooding during the hurricane. They should navigate to the website on their own devices and write the answers to the following questions on a piece of scrap paper: Walk around and check students’ answers and address any problems with understanding. 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. 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. Ask: What general trend do you see? 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. Students use maps and graphs to understand how the frequency of billion-dollar natural disaster events has changed over time. (Answer: Students may notice some types of events seem to be grouped in certain parts of the country.) 2017. 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. 3. Continue playing the video. On Earth, climate scientists must account for temperature fluctuations, wind patterns, ocean currents, land surface characteristics and much more. Learn more about environmental hazards with this curated resource collection. As a result, more countries are acting on the imperative to implement national and local disaster risk reduction strategies. These include changes in pr… More needs to be done to prevent new risks, which are already emerging owing to increasing urbanisation, the threat of climate change and other risk drivers. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. (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.) In Canada, the average temperature increased by 1.7°C during the same time period, about double the global average (Figure 1). Climate models provide a glimpse of the future, and while they do not agree on all of the details, most models predict a few general trends. 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 addition to property damage, floods, on average, kill more people than tornadoes, hurricanes, or lightning strikes in the United States each year. 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 climate varies naturally from year to year and decade to decade. When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. Current climate change is mainly caused by human activities that release greenhouse gases to the atmosphere. Ask: What patterns do you notice in the locations of these events? 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. More recently, scientists have begun to explore the role that climate change plays in specific weather-related natural disaster events. Now scientists are increasingly looking at the role climate change is playing in specific disaster events. Human and natural systems are influenced by climate variability and hazards, with the negative impacts most severely felt in developing countries. Climate-Smart Agriculture (CSA) is an approach to help the people who manage agricultural systems respond effectively to climate change. Climate refers to the kind of weather that's typically expected in a region. Ask: What does the black line represent? Review the basic causes and consequences of climate change before moving to the next step. 2006).It also contributes to increased climate extremes and exacerbates adverse impacts (Birkmann and Mechler 2015).Climate change is just one factor influencing certain hazards; it can contribute to disasters where vulnerability … Figure 1.1: Polar bears walking on melting ice. In an increasingly interconnected world, we are seeing that disasters can also result in synchronous failures. Hurricanes have three main parts, the calm eye in the center, the eyewall where the winds and rains are the strongest, and the rain bands which spin out from the center and give the storm its size. This process is often called the greenhouse effect. Monitor the news for weather-related disaster events around the world. 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. The link between land use and the climate is complex. Students examine key causes and impacts of climate change on Earth’s atmosphere and oceans, as well as mitigation and adaptation strategies. This figure shows changes in global and Canadian average temperature relative to the 1961 to 1990 reference period. The key is for students to understand that a trend over time does not mean that every year will have more billion-dollar disaster events than the last. The sun’s energy warms the Earth and the warmed Earth releases heat to the atmosphere. Similarly, they may observe that some occurred in agricultural areas, which may have affected crops and damaged the economy. It means changing our activities and decisions so that we reduce the negative impacts of climate change and become more resilient. Deforestation contributes to the increase in CO2 in the atmosphere and climate change © Lou Levit. 2015. All of these pose risks for agriculture, food and water supplies. Why or why not? National Geographic Headquarters 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. Would these types of disaster events continue to occur even without climate change? Yet, in spite of the evidence at hand, climate change remains the toughest, most intractable political issue we, as a society, have ever faced. Climate change will affect certain groups more than others, particularly groups located in vulnerable areas and the poor, young, old, or sick. Learn more about the impacts of climate change: Dealing with climate change requires both mitigation and adaptation actions. And what are the effects of climate change? It is one of the most pervasive and threatening crises of our time. Terms of Service |  Ask students: What are some factors that may explain this general trend?

After students have completed the worksheet while watching Climate change is part of California’s perfect recipe for intense wildfire, distribute another copy of the worksheet to each group. Then replay the video, and this time ask students to complete the worksheet as they watch. In the United States, the amount of greenhouse gas emissions has held steady since 1990–even though our economy and our population has grown. Burning fossil fuels (coal, oil, gas) and some industrial processes are the main sources of carbon dioxide. Without drastic changes, it's expected that there will be devastating changes in biodiversity and ecosystems. 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 The environmental hazards you face depend on where you live. Provide support for students as they work by pausing the video, rewinding, and modeling how to answer the questions as needed. She or he will best know the preferred format. The projections of future climate patterns are largely based on computer-based models of the climate system that incorporate the important factors and processes of the atmosphere and the oceans, including the expected growth in greenhouse gases from various socio-economic scenarios for the coming decades.

It also includes changes that are forecast over the next few days, for example, in temperature and rainfall. The heavy rains and increased temperatures lead to increased humidity which increases the chance of mosquito breeding and survival. This shrinking sea ice disrupts normal ocean circulation and creates changes in climate and weather around the globe. Catastrophic weather events include hurricanes, tornadoes, blizzards, and droughts, among others. What causes climate change? Use these resources in your classroom to help your students understand and take action on climate change. Natural Disasters and Climate Change Natural Disasters and Climate Change Students use maps and graphs to understand how the frequency of billion-dollar natural disaster events has changed over time. (Answer: They should see that the frequency of billion-dollar events is generally increasing over time.) Review the environmental conditions that make wildfires more likely. Deforestation can involve conversion of forest land to farms, ranches, or urban use. Disasters displace three to ten times more people than conflict and war worldwide. Learn more about the causes of climate change and the greenhouse gas effect: Each of the last three decades has been warmer globally than any decade on record. Medical costs and loss of life are not considered in the final number. Credit: The Select Committee on Energy Independence and Global Warming. Ask: What types of natural disasters are shown on the map? Weather refers to the actual atmospheric conditions that are being experienced now. 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.
