Hey guys it’s ok if you don’t know the answers to some of the questions, later as you navigate this module surely you will learn more. supporting renewable energy initiatives. Pre- Requisite Knowledge We are usually confused if we are thinking of climate and weather. Sometimes we could not differentiate these two. However, how are the weather and climate being different from each other? Weather is described as the immediate condition in a specific place. For example, if you see that it is raining outside right now, that is a way to describe today’s weather. Rain, snow, wind, hurricanes, tornadoes — these are all-weather events. On the other hand, the climate is more than just one or two rainy days. It describes the weather conditions that are expected in a region at a particular time of year. It is also 2 the usual weather of a place. The climate can vary in every season. A place might be mostly warm and dry in the summer, while it may be cool and wet in the winter. Different places can have different climates. https://clickonenglish.blogspot.com/2018/11/weather-vs-climate.html https://www.slideshare.net/stevenheath148/weather-and-climate-73293753 Now that you have a solid grasp on the difference between weather and climate, let’s examine the specific phenomena currently affecting our climate.

Now, let’s go deeper this time. You will be provided with an activity that will broaden your understanding about climate change. 2 RE AD ME! In our last module, we learned about why natural disasters happen and how they affect people and the world around us. We talked about things like earthquakes, floods, and storms, and how they can be tough for communities. Now, we're moving on to a new topic: climate change. This is all about how our planet's weather has been changing over a long time and how it's impacting the environment. So, it's like a fresh start to learn something new! In this module, we'll focus on understanding climate change and how it affects our environment. Climate change means long-term changes in things like temperature and rainfall in a specific area. When we talk about "global climate change," we're referring to these long-term changes happening all over the Earth. This includes things like temperatures going up and changes in how much rain falls. This also leads to other important effects like: • The sea levels rising • Glaciers on mountains getting smaller • Ice melting faster in places like Greenland, Antarctica, and the Arctic • Changes in when flowers and plants bloom. So, in this module, we'll explore whether climate change is something that naturally happens, something people cause, or maybe a combination of both. Are You excited to learn? more? Alright, then what are you waiting for get ready with the next activity. 4 EXPLORE Activity 1: Climate Change Explorer: Spotting the Nature’s Makeover Directions: Analyze the various impacts on us and to the environment from the given pictures.

EXPLAIN "Scientists started learning about climate change way back in the early 1800s. They noticed some big changes in Earth's past, like the ice ages, and figured out something called the natural greenhouse effect. Later, in the late 1800s, scientists began to say that things people do, like burning fuels, could also change our climate. They had different ideas about what causes climate change, like volcanoes and changes in the sun's energy. Climate change means big and long-lasting changes in how our weather works. For example, it might make some places hotter or wetter than usual, or even cause more big storms. Climate change happens because of different things, like how the oceans move, living things like plants, energy from the sun, and even big movements in Earth's plates or volcanoes. One thing that people are doing, like using a lot of energy from burning fossil fuels, is making our planet warmer. This is what we call 'global warming,' and it's a big part of what we mean when we talk about 'climate change.' . These changes are primarily driven by human activities, including burning fossil fuels, deforestation, and intensive livestock farming. These activities release significant quantities of greenhouse gases into the atmosphere, which act like a blanket, trapping heat and causing global warming. 24 Greenhouse gases, which include carbon dioxide (CO2), methane, nitrous oxide, and fluorinated gases, occur naturally in Earth's atmosphere. However, human activities have significantly increased their concentrations, particularly CO2. It is the most prevalent greenhouse gas produced by human activities, responsible for 64% of human-induced global warming (United States Environmental Protection Agency [EPA], n.d.). For example, the burning of coal, oil, and gas releases CO2 and nitrous oxide into the atmosphere. When forests are cut down (deforestation), trees lose their ability to absorb CO2, and the carbon stored in them is released into the atmosphere, further contributing to the greenhouse effect. Livestock farming, especially cows and sheep, produces large amounts of methane when they digest their food. Fertilizers containing nitrogen led to the release of nitrous oxide, and fluorinated gases, though released in smaller quantities, have a much more potent warming effect compared to CO2 (EPA, n.d.). Is global warming and climate Change one and the same? Global warming, a critical consequence of climate change, is evident in the rise of the Earth's average temperature. As of March 2020, the global average temperature was 1.16ºC (2.09 ºF) higher than in the late 19th century. Each of the past three decades has been warmer than any preceding decade since records began in 1850. Scientists agree that human activities have been the primary cause of observed warming since the middle of the 20th century. Unlike past natural climate fluctuations, today's global warming is largely attributed to the increase in heat-trapping gases produced by human activities. Over the last five decades, natural factors would have led to a slight cooling of Earth’s surface temperature, but human-induced emissions have reversed this trend. Furthermore, the current rate of global warming is unprecedented, occurring much faster than at any point since modern civilization and agriculture developed over the past 11,000 years or during any warm interglacial periods of the last million years (Kennedy and Lindsey, 2015). What are the other impacts of climate change on the environment? 1. Rising Temperature – Global temperatures are increasing. The higher the temperature the higher rate also of heat related illnesses. This can harm the ecosystem. Wildfires start more easily and spread more rapidly when conditions are hotter. 24 2. Melting Ice and Rising Sea Levels – as temperatures rise, polar ice caps and glaciers melt faster. As these ice sheets and glaciers melt, the water eventually runs into the ocean, causing the sea level to rise. This can lead to coastal flooding, erosion, and threats to coastal communities. 3. Extreme weather event – climate change is linked to frequent occurrence of typhoons, droughts, floods, and wildfires. These events can cause damage to communities, agriculture, and natural habitats. 4. Disruption of Ecosystem – Changes in temperature and weather patterns can disrupt the ecosystem. This may cause the displacement (animal migration) or loss of many species. Climate change combined with habitat disruption may result in loss of biodiversity. 5. Ocean Acidification - Increase carbon dioxide levels in the atmosphere which is mainly caused by burning of fossil fuels leads to ocean acidification. This harms marine life, especially creatures with calcium carbonate shells like corals and shellfish. 6. Altered Rainfall Patterns - Changes in precipitation patterns can lead to droughts in some regions and increased rainfall in other regions. (El niħo and la niħa phenomena) 7. Food shortage - food production (crops, availability of fish, and other food sources) becomes more difficult and uncertain due to changes in weather patterns, extreme weather events and environmental disruption. 8. Health Risks – climate change can worsen health problems. Many heat- related illnesses arise today.
