Essay. Is global climate change (global warming) man-made or not? Over the last hundred years the Earth has been warming. This warming is believed to lead to many issues such as increasing of nature disasters, weather changes and draught. All of these consequences could become a reason of economic decay in many countries, especially in some undeveloped countries. Therefore it is very important to find out who is guilty of the climate changing. Many people are confident that the reason of global warming is man made carbon dioxide. Over the last hundred years our society has been developing very fast: there has been built a huge amount of different factories, has been made so many inventions in all fields of human activity. Unfortunately only recently we have noticed that by making our life more comfortable and more enjoyable we destroy nature and cause appearance of ozone holes wh...
Environmental problems Nimi Klass Biodiversity The variety of life on Earth, its biological diversity, is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. In some way or form, almost all cultures have recognized the importance of nature and its biological diversity for their societies and have therefore understood the need to maintain it. Yet, power, greed and politics have affected the precarious balance. Why Is Biodiversity Important? Who Cares? · Why is Biodiversity important? Does it really matter if there aren't so...
The Greenhouse Effect: Scientists are sure about the greenhouse effect. They know that greenhouse gases make the Earth warmer by trapping energy in the atmosphere. Climate Change: Climate is the long-term average of a region's weather events lumped together. For example, it's possible that a winter day in Buffalo, New York, could be sunny and mild, but the average weather the climate tells us that Buffalo's winters will mainly be cold and include snow and rain. Climate change represents a change in these long-term weather patterns. They can become warmer or colder. Annual amounts of rainfall or snowfall can increase or decrease. 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 o...

The Chiltern Hills Ursula 11. kl · The Chiltern Hills are known locally as just The Chilterns and are a chalk escarpment in the south-east of England, lying a few miles north-west of London. · They cover four counties and combine beautiful scenery with interesting history. · The Chilterns begin in Oxfordshire in the Thames Valley and stretch north-east through Buckinghamshire and Bedfordshire to Hitchin in Hertfordshire. They comprise of chalk hills covered with beautiful beech woods, wild flowers, and a variety of wildlife. History · In pre-Roman times, the Chiltern ridge provided a relatively safe and easily negotiable route across southern Iron Age England, thus the Icknield Way (one of England's ancient trackways) follows the line of the hills. · The name "Chiltern" comes from the Cilternsæte, a tribe that occupied the area in the early...

Animals shrinking in the heat This article was published in Daily mail, on 17 October 2011. The author of the article is Tamara Cohen. The article discusses about animals who are shrinking due to global warming. Scientist have warned, that animals such as sheep, deer, birds and reptiles are shrinking due to climate change. Researchers say warmer temperatures over the past few years have made some animals adapt to need less body fat to survive while others are struggling for food. In the next few decades, some types of mammals, fish, birds and plants are getting smaller and evolve into miniature versions of what they are today. This could force some creatures, that people eat, to become extinct, Dr David Bickford from the National University of Singapore reviewed research showing creatures from deer to tortoises, gulls, goshawks and even polar bears have already shrunk over the past 50 years. 'Because recent climate change may be fast...

The Earth's climate has been changing constantly over its history. Once, all climate change occurred naturally, but recently, people have also started altering the climate. We are sending more and more greenhouse gases into the atmosphere. The average global temperature has increased by about 0.5 °C over the past century. Scientist expect it to increase up to an additional 3 °C over the next on 100 years. People who are living in cold places may have a chance to grow new crops if the climate gets warmer. At the same time in some parts of the world, people won't be able to grow the food they need. Global warming will make the sea level higher because it'll make the glaciers melt. When water expands in the ocean, it takes up more space and the level of the seas rise. If global warming gets worse, some kinds of plants and animals will become extinct. So as a result we have to slow down the global warming.

Savanna A savanna is a grassland ecosystem with scattered trees or shrubs. In savannas trees are small or widely spaced so that the canopy does not close. It is often believed that savannas are characterized by widely spaced, scattered trees, however in many savanna communities tree densities are higher and trees are more regularly spaced than in forest communities. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of C4 grasses. Savannas are also characterised by seasonal water availability, with the majority of rainfall being confined to one season of the year. Savannas can be associated with several types of biomes. Savannas are frequently seen as a transitional zone, occurring between forest and desert or prairie. Although the term savanna is believed to have originally come from a Native American word describing "land which is without trees but with ...
Humans are changeing the planet with their ordinary life. The principle cause of climate change is the increase in carbon dioxide concentrations in the atmosphere. The main cause of that is the burning of fossile fuels. This is leading to the global warming. People have discovered a way to reduce the amount of CO2 in the atmosphere. It is possible to seperate the CO2 from the other gases by adding liquid which is very good at absorbing CO2. Then it can be pumped to underground. Scientist came up with this idea because methane gas has been down there for thousands of years and it has not come up. So they expect that the CO2 won't be coming up either. To be sure of that, they are coing to make a test and drill two wells to take purified CO2, inject it into the ground and monitor the physical changes that CO2 undergoes. This technology is really new and it is unknown to people. It has not been proven yet, so people are scared and concerned...
Answers for the IPCC Summary. 1.Radiative forcing is a measure of the influence that a factor has in altering the balance of incoming and outgoing energy in the Earth-atmosphere system and is an index of the importance of the factor as a potential climate change mechanism. 2.The three main things that alter the energy balance of the climate system are the changes in the atmospheric abundance of greenhouse gases and aerosols, in solar radiation and in land surface properties. 3.The two sources for the increased concentration of CO2 in the atmosphere are production, distribution and consumption of fossil fuels and as a by-product from cement production. 4.The two main sources of methane pollution are agriculture and fossil fuel use. 5.Volcanic aerosols are not included to the list because of their episodic nature. 6.The world's oceans absorb more than 80% of heat. 7.The total 20th-century rise is estimated to be 0.17...
Efficient initiatives to help protect the environment Just like our bodies, the environment functions best when it's in balance. Unfortunately, we're not quite there. Many of us believe that we lead lives that respect nature but our consumption habits give us away. Many little habits that seem to be sustainable are in fact polluting. Along with pollution, issues like depletion of resources, the rise of consumerism, and the "throw away" culture have led to serious issues. That being said, the fight's not over yet. Fortunately, more people than ever are both aware of and active in the protection of the environment. To protect the environment, waste management and recycling are crucial. When we recycle, used materials are converted into new products, reducing the need to consume natural resources. If used materials are not recycled, new products are made by extracting fresh, raw material from the Earth, through mining and forestry. R...
Hello ladies and gentelmans Today I'm going to talk about how global warming will change the way we live in future. In fact durning the twentieth century global temperature went up by over 0,7 Celsius degree. It looks pretty small number but even slight Climate change leads to serious consequences. Firstly, global warming will cause that glaciers start to melt. And as a result, the water level will raise and cities and villages which are located near oceans and sees will be flooded. Secondly, if we don't stop global warming, we will bserve more examples of extreme weather such as heat waves, storm clouds, which may lead to floods, droughts and forest fires. Next conseqences of global warming is that oceans temperature will go up. It is likely that it will cause an increase in activity of hurricanes, what will cause many unimaginable destructions. Also, ice will start to melting in Alaska, so it will lead to extremination of ma...
Environmental Problems and Sustainability The environment is our physical surroundings. This includes both human (man- made), social and physical (natural) features. Natural features include soil, the atmosphere, vegetation and wildlife. Human features include things such as culture, language and political systems. Geographers are concerned about human action in the environment. Human interference with the environment causes problems such as soil erosion, global warming and acid. You may ask how we as individuals can have an impact on the environment. Our actions can help to increase the problems highlighted above. For example turning off lights that are not being used helps to reduce global warming. Until recently, concern about the environment revolved almost exclusively around local and national problems. Over the past two decades, however, scientists have increasingly focused attention on more far-reaching environmental threats,...
Global Warming One of the biggest issues our planet and its inhabitants are facing nowadays is global warming. Global warming, also often referred to as the greenhouse effect, has not always been a problem. However, over the last centuries, since the Industrial Revolution things have changed. Polar regions are melting, species are dying, climate zones are shifting, migration patterns for animals such as polar bears and birds are being disrupted our world as we know it is changing. Some scientists believe that the climate will reach a tipping point, a point at which even a tiny additional increase would throw the system into violent change. We started doing harmful things and only now do we realize what we have done and what we are doing. At this current rate by the middle of next century the Earth's temperature may rise a predicted from 2 to 6 degrees Celsius. This may not seem as much but with the E...
Human overpopulation Liis Lukk MJ15 What is overpopulation? • Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. • Human overpopulation is among the most pressing environmental issues • Overpopulation can result from an increase in births, a decline in mortality rates, an increase in immigration, or an unsustainable biome and depletion of resources • Human population has been rising continuously since the end of the Black Death, around the year 1350 • The most significant increase has been since the 1950s, mainly due to medical advancements and increases in agricultural productivity • The recent rapid increase in human population over the past three centuries has raised concerns that the planet may not be able to sustain present or future numbers of inhabitants. Loss of Fresh Water • Most of the freshwater resources are ...

The Importance of English History Essay There is not a single country in the world without a history it can be either long or short, yet still a unique part of the existence. England has had many colourful events throughout the history, but some have dominated over the others and therefore all together formed a country we can see nowadays: the Great Britain. Starting from the beginning, Britain was part of the mainland until about 6000 BC, when it became an island. Ever since then it has been developing slightly different from the other part of the Europe. For example, when two parts separated, some animals had already adopted the life on the island and did not move back to the mainland. They suited their appearance more comfortable for the isolated island and learned how to survive in the wet climate and rather heavy air. The first inhabitants the Iberians also h...

As time goes on, society will have to face many problems. The biggest issues are with the environment that is around us. It is surprising how our traditional habits can contribute so strongly to environmental problems. They affect the whole world, even our little country Estonia. We, as individuals, are capable of doing anything to save our world. To begin with, everyday life has been disturbed because of COVID-19. Life stopped during this pandemic not only in China where it started, but also across the globe. When we look at the present situation, very many people are confined to their own homes. In Estonia, students can’t go to school normally, they have to stay behind the computer every day and it is very exhausting. Many parents have lost their jobs because of the virus. And still there are people who won’t listen to the government rules and spread the virus further. Secondly, global warming is increasing at an alarming rate wit...

Humans are clearing our forests for wood and timber. The foodchain is disturbed and animals will die. *Wildlife trade: Poaching and wildlife trade are another common threat to animals. International wildlife trade has also been linked to drugs trade. The most common anilmal trade is pet trade, such as orangutangs. Animals are also killed for fur(tigers, leopards, cheetahs) *Climate change: It has been recently suggested that warmer global temperatures may be affecting animals.

Green Technologies - innovation and climate change sustainagility Scientists can examine ice, but they cannot tell out anything about our future. Even if scientist has lived thousand years he won't be able to do it. The graph in video shows that the amount on carbon dioxide rises and then rises the temperature, but it is not so, it is exactly the opposite. One way to save energy is to build better buildings, because big headquarters are built to last only for 30-35 years. Building them up and pulling them down needs a lot of energy and about 30% of building energy is spent on it. It is thought that if in Tokyo 50% of all roofs are green it will save 1 million dollars a day of Tokyo businesses in cooling costs. Street light use 5% of energy, but it can be reduced to 2%. Usual TVs should be replaced with Plasma TV, because it saves energy more. By driving electic-car, it is possible to save energy a...
ICE AGE The earth is very old. During its long history there have been many changes in climate. Between one and two million years ago one of these changes took place the great Ice Age began. It grew colder in the Far North. More snow fell in the winter than could melt away in the summer. The snow grew deeper and deeper. It changed to solid ice. As more snow fell, the ice grew thicker. It began to move. Great sheets of moving ice, or glaciers, were formed. The edges of the sheets were pushed outward. At last the ice covered most of what is now Canada. And it spread southward into what is now the United States. The ice was probably a mile deep in places. It moved over hills and valleys, rivers and forests. It moved slowly perhaps only a foot a day. Millions of plants were buried by the ice. Many animals moved south. Among the animals able to stand the cold near th...

Palm oil Palm oil is a type of edible vegetable oil that is derived from the palm fruit, grown on the African oil palm tree. Oil palms are originally from Western Africa, but can flourish wherever heat and rainfall are abundant. Today, palm oil is grown throughout Africa, Asia, North America, and South America, with 85% of all palm oil globally produced and exported from Indonesia and Malaysia; but most of the time not using sustainable measures. The industry is linked to major issues such as deforestation, habitat degradation, climate change, animal cruelty and indigenous rights abuses in the countries where it is produced, as the land and forests must be cleared for the development of the oil palm plantations. According to the World Wildlife Fund, an area the equivalent size of 300 football fields of rainforest is cleared each hour to make way for palm oil production. This lar...

The most pressing environmental issues in Estonia The earth is considered as one of the most beautiful planets in the Universe. Unfortunately, our planet is suffering due to many problems which should be solved before it is too late. Of course our country is not an exception. The major problems that are facing our country today are air and water pollution and recycle problem. Also we have, for example, deforestation problem and traffic jams, for instance, in Tallinn in rush-hour. Nevertheless, those problems are not so significant than previous. One of the biggest problems in Estonia is air and water pollution. One example of air pollution is exhaust fumes. Today we have a lot of transport: cars and buses, in the main in our capital. Gases which are produced by cars contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the green house effect. Furthermore, it will ...

Early History The first inhabitants of Canada were native Indian people who were called as Inuits. They are believed to be in Canada since about 10000 BC. The Inuits came to Canada from Asia crossing the Bering land bridge. The earliest discoveries in Canada were made by the Vikings. In AD 985 Vikings sailing from Iceland to Greenland were blown westward off their course and the Vikings sighted the coast of Labrador peninsula. The report of forested areas encouraged further exploration because the colonies in Greenland which belonged to the Vikings lacked lumber. In AD 1000 Leif Ericson became the first European to land in North America. The first colony was established what was described as Vinland by the Vikings. It was located on the northernmost tip of todays Newfoundland. There has also been a theory that the Vikings penetrated Hudson Bay and reached the Great Lakes region but recent investigations have...
Environmental issues in Estonia The Earth is considered to be the most beatiful planets in the Universe. But our planet is threaten by environmental problems. Even a small country like Estonia can make difference. Our capital city is fighting against air pollution. But people produce much refuse and ways of recycling are getting old. Water pollution is also a problem in Estonia. We have factories that let their waste run into rivers. One of the biggest problems in Estonia is air pollution. Our air is polluted by exhaust fumes, because today we have a lot of cars, buses and other machines. In 2009 we had 407 cars to thousand inhabitants, which is lower than European Union average, but this number is still high. Because cars produce gases that contain carbon dioxide. This carbon dioxide in the air causes global warming, which is the result of the greenhouse effect. Tallinn wants to fight against it by offering public transportati...

Kliimamuutus. Kliimamuutus on pika aja jooksul ilmnev muutus ilmastikuolude statistilistes näitajates. Klimaatiliste näitajate muutus võib hõlmata ajalist perioodi aastakümnetest miljonite aastateni. Sõna uus praegusaegne kasutamine, viitab tavaliselt kliimamuutusele tänapäevases kliimas. Selle muutuse põhjuseks peetakse suuresti inimtegevust ja see on enam tuntud globaalse soojenemise nime all (Wikipedia.org ; Klii...
