Why is climate change such a huge concern? What is it exactly? You must be able to demystify climate change and present it as a process when discussing it. If you understand what causes climate change and how it occurs, then it should be easier to explain it. First, look at the two definitions and then proceed to the Activity.\n<\/p>\n<p><b>Definition 1: United Nations \u2013 Climate Action (2023)<\/b><br \/>\nClimate change refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.\n<\/p>\n<p><b>Definition 2: National Aeronautics and Space Administration (NASA) (2023)<\/b><br \/>\nClimate change describes a change in the average conditions \u2013 such as temperature and rainfall \u2013 in a region over a long period of time. NASA scientists have observed Earth\u2019s surface is warming, and many of the warmest years on record have happened in the past 20 years.\n<\/p>\n<div class=\"panel iDevice\">\n\t<div class=\"panel-heading idevice-heading\">\n\t\t<div>\n\t\t\t<img decoding=\"async\" class=\"pedagogicalicon\" alt=\"activity\" src=\"https:\/\/course.fossdle.org\/baccc\/wp-content\/themes\/oeru-course\/idevices\/Icon_activity.png\">\n\t\t<\/div>\n\t\t<div>\n\t\t\t<h2>Activity<\/h2>\n\t\t<\/div>\n\t<\/div>\n\t<div class=\"panel-body\">\n\t\t<div class=\"col-md-12\">\n\t\t\t<\/p>\n<p>Looking at the definitions from the two sources, and for the sake of having a very clear understanding of climate change, answer the following questions in your learning journal:<br \/>\n1. These definitions are basically the same. Which of the two definitions do you understand and will you be able to use comfortably when explaining climate change?<br \/>\n2. Write your own definition of climate change, in your own language or in simple English, for somebody who is illiterate.<br \/>\n3. Share this definition with three people of different ages (a child, a middle-aged person and an elder) in your community, and find out if they understand your definition.<br \/>\n4. In your journal, rate their understanding from 1 to 10 (with 10 being \u201cunderstood it completely\u201d). Explain what you think caused the differences in their level of understanding.\n<\/p>\n<p>\n<\/p>\n<p>\n\t\t<\/div>\n\t<\/div>\n<\/div>\n<p>\nIs climate change a big deal to you? Most definitely, climate change should and must be a big deal to everybody. As a climate champion, it will be your (part-time) responsibility to help people understand this. Proceed to the next learning activity, which will help you get ready for interactions with people who have diverse perspectives on climate change and who do not truly understand what it is.\n<\/p>\n<p>\n<\/p>\n<div class=\"panel iDevice\">\n\t<div class=\"panel-heading idevice-heading\">\n\t\t<div>\n\t\t\t<img decoding=\"async\" class=\"pedagogicalicon\" alt=\"activity\" src=\"https:\/\/course.fossdle.org\/baccc\/wp-content\/themes\/oeru-course\/idevices\/Icon_activity.png\">\n\t\t<\/div>\n\t\t<div>\n\t\t\t<h2>Activity<\/h2>\n\t\t<\/div>\n\t<\/div>\n\t<div class=\"panel-body\">\n\t\t<div class=\"col-md-12\">\n\t\t\t<\/p>\n<p>You and some members of your family are watching and listening to the news on television about severe downpours that caused flooding across most parts of your country, including your town or village. According to the national meteorological weather forecast, these torrential rains are likely to linger for two weeks and spread through the country with the possible effects of further flooding, mudslides, infrastructure damage and fatalities. The heavy rains are attributed to climate change.\n<\/p>\n<p>After this news report, you listen to your family members comment on it. Your response is the last one. Write in your learning journal how you would answer each person to enlighten them and, in particular, to address myths, misinformation, ignorance and denial. In your response, take into consideration the highlighted words in their conversation. As you proceed with this lesson, you will learn more information that you can keep adding to your response to your family.\n<\/p>\n<p>\n<i><b>Grandma:<\/b> It looks like this awful weather is here to stay. You know, in the past, we never had such rapid occurrences of these natural disasters, and I keep hearing that climate change is to blame. I\u2019m not sure what they mean, but I do know that <b>it happens because the gods are angry with us<\/b>. We need to do something to appease them.<\/i>\n<\/p>\n<p><i><b>Cousin 1:<\/b> Yes, Granny, <b>I\u2019m also not sure what this climate change is all about, but we\u2019re constantly held responsible for it.<\/b> Hey, Cousy, can we go get food, water and cooking gas for the upcoming rainy days, please?<\/i>\n<\/p>\n<p><i>Cousin 2: Can you imagine being blamed for something like climate change? Am I God? Sorry Cousy, <b>my car is down. It has been leaking oils and emitting a lot of smoke lately.<\/b> Besides, I heard that <b>there is a serious shortage of food and clean water.<\/b> Maybe our uncle can help us out. Hey, Uncle, you look sad. Are you okay?<\/i><\/p>\n<p><i><b>Uncle:<\/b> I\u2019m thinking about this climate change issue, but I don\u2019t care who is to blame; for now, all I am worried about is that my crops are being ruined. I wasted money on the <b>pricey fertilisers, fungicides and pesticides I used<\/b> last week. This weather is delaying my progress at the farm. I was also hoping <b>to clear more vegetation<\/b> for the expansion of my farm, but this weather has thwarted my plans.<\/i>\n<\/p>\n<p><i><b>Cousin 1:<\/b> I don\u2019t know about you guys, but as for me, I\u2019m not voting for this useless government again. They use this climate change to cover up their failures. This nonsense of <b>blaming us for rising oceans, floods, extremely high temperatures, bleached corals and diminishing forests and even fisheries<\/b> must stop.<\/i><\/p>\n<p>&#8221;&#8217;<i><b>Cousin 2:&#8217;<\/b><\/i> You are right, Cousy; there is a shortage of gas, and we are experiencing power cuts. I don\u2019t know why they\u2019re not producing enough electricity because it\u2019s just a matter of <b>burning more coal<\/b>, right? And coal is abundant in our country.\n<\/p>\n<p><i><b>Uncle (turning to you):<\/b> You are awfully quiet \u2013 or are you also bored by this climate change thing?
