Climate Change Concept, Causes, Effects and Solutions By: Nadia, Zeina, Nadin, Nora, and Ala’
What is Climate?? • Climate: The average weather (usually taken over a 30-year time period) for a particular region and time period. It is not the same as weather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere. • Climatic elements include precipitation, temperature, humidity, sunshine, wind velocity, phenomena such as fog, frost, and hail storms, and other measures of the weather.
Global Warming • Global Warming: refers to an average increase in the Earth's temperature, which in turn causes changes in climate. • A warmer Earth may lead to changes in rainfall patterns, a rise in sea level, and a wide range of impacts on plants, wildlife, and humans. When scientists talk about the issue of climate change, their concern is the global warming caused by human activities.
Greenhouse • Most greenhouses look like a small glass house. • Greenhouses are used to grow plants, especially in the winter. • Greenhouses work by trapping heat from the sun. The glass panels of the greenhouse let in light but keep heat from escaping. This causes the greenhouse to heat up, and keeps the plants warm enough to live in the winter.
Greenhouse Effect • Greenhouse Effect:The effect produced as green-house gases allow incoming solar radiation to pass through the Earth's atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. This process occurs naturally and has kept the Earth's temperature about 60 degrees Fahrenheit warmer than it would otherwise be. Current life on Earth could not be sustained without the natural greenhouse effect.
Greenhouse Gazes • Greenhouse gases in the atmosphere behave much like the glass panes in a greenhouse. • Sunlight enters the Earth's atmosphere, passing through the blanket of greenhouse gases. As it reaches the Earth's surface. • Once absorbed, this energy is sent back into the atmosphere. Some of the energy passes back into space, but much of it remains trapped in the atmosphere by the greenhouse gases, causing our world to heat up. • Greenhouse gases include water vapor, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), halogenated fluorocarbons (HCFCs) , ozone (O3), per fluorinated carbons (PFCs), and hydro fluorocarbons (HFCs).
Who Causes the Climate Change!! • We do!!! • We send greenhouse gazes to the atmosphere. • Industrial practices; cars, planes, factories, electricity, and solid trash. • Environmental practices; deforestation, and pollution.
What If We Continue!! • Human Health will be affected directly and indirectly. • Food Supply will be affected. • Wild Life will be affected. • Sea Level will rise. • Ecological Systems will be affected. • Weather Changes.
Human Health • Direct Effect is caused by warm temperatures and high humidity. • Untreated, heat stress can be a very serious medical problem. • More hot days increases the possibility of heat related health problems. • Nasty diseases like Malaria, will spread. • Ecological disturbances, pollution, changes in food and water supplies, and coastal flooding are all examples of possible impacts that might affect human health indirectly.
Food Supply • Global Warming may make the Earth warmer in cold places. People living in these places may have a chance to grow crops in new areas (North). • But climate change also might bring droughts to other places where we grow crops. In some parts of the world, people may not have enough to eat because they cannot grow the food that they need.
Ecological System • Climate change may alter the world's habitats and ecosystems. • Life depends on a delicate balance of rainfall, temperature, and soil type. • Global Warming could upset this balance and seriously endanger many living things. • Climate Change used to occur slowly, allowing plants and animals to adapt to the new environment or move somewhere else. However, if future climate changes occur as rapidly as some scientists predict, plants and animals may not be able to react quickly enough to survive.
Sea Level • The ice of the poles is melting. Some of it is melting fast. The Arctic sea ice gets less every year and the great frozen continent of Antarctica is losing ice too. Other seas, like the North Sea, are warming too. This means that fish which need colder waters have to swim north and this can have bad effects of both fishing and seabirds. • All the ice and glaciers that melt will start to fill up the oceans and make them overflow on land (floods), and the water itself will take up more space simply because it is warmer. • Some of the best land for growing food is the most low-lying, that means it will be flooded first, so it will affect soil where salt is harmful. • Loads of people will go hungry and many more will have nowhere to live.
Wheather Changes • As the earth is warming up, the weather is going to get more violent and unpredictable. • Hurricanes and storms, for example, will become more powerful.
Is It Too Late to Save Our Planet?! • No it is not. • We can: • Plant Trees. • Recycle. • Walk, ride bikes instead of cars and buses. • Save electricity and other sorts of energy. • Read and Spread Awareness of Climate Change among people. • Use cars that save energy. • Find safe energy sources like the solar energy, to replace the fuel. • Use Energy Star machines; those machines save energy.
In Palestine… • We here in Palestine like others around the world participate in the climate change.
Climate Change Causes • Industry: • Industrial practices don’t have great effect in this field since we don’t have very improved and enhanced industries. • Air pollution sources like cars, output of modest factories. • Solid Trash • Environmental Practices: • Deforestation; cutting trees by people and most by occupation.
What We have Done • As a group of students who care about this issue, with the help of the RI-SOL OSM at our school we searched this topic. • We organized a planting day, to plant trees and flowers in our school garden and in the streets around it. • We organized an Art Workshop in our school to enlighten students about this topic, and to let them participate in UNEP painting competition which is about the Climate Change
Interview • We interviewed Ms. Yara As’ad, the P.R director at BerZiet Pharmaceutical Company BPC in Ramallah. • BPC offered more than 10000 free tree to be planted all over Palestine in “ Green Palestine” Campaign. • They are interested in environment to compensate for pollution caused by companies and factories. • They like our activities and offered us free trees for our planting day. • They want to collaborate with us in future work concerns the environment.
What we will do • We will apply what we have learnt about the Climate Change in our daily lives. • We will participate in enlightenment meetings and campaigns to spread awareness among people about this topic. • Participate in presentation project organized by BPC about “Trees and Environment”
