CLIMATE CHANGE AND GLOBAL WARMING

Climate change

Climate change, also called global warming, refers to the rise in average surface temperatures on Earth. An overwhelming scientific consensus maintains that climate change is due primarily to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.

The green house effect

While other planets in Earth's solar system are either scorching hot or bitterly old, Earth's surface has relatively mild, stable temperatures. Earth enjoys these temperatures because of its atmosphere, which is the thin layer of gases that cloak and protect the planet. However, 97 percent of climate scientists agree that humans have changed Earth's atmosphere in dramatic ways over the past two centuries, resulting in global warming The exchange of incoming and outgoing radiation that warms the Earth is often referred to as the greenhouse effect because a greenhouse works in much the same way. Incoming UV radiation easily passes through the glass walls of a greenhouse and is absorbed by the plants and hard surfaces inside. Weaker IR radiation, however, has difficulty passing through the glass walls and is trapped inside, thus warming the greenhouse. This effect lets tropical plants thrive inside a greenhouse, even during a cold winter.

Consequences of global warming

There are two major effects of global warming: the increase of temperature on the earth by about 30 to 50C (5.40 to 90Fahrenheit) by the year 2100 are Rise of sea levels by at least 25 meters (82 feet) by the year 2100. Other consequences are listed below:

• Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.

• Amounts and patterns of precipitation are changing.

• The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.

• Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts heat waves, and tornadoes.

• Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.

• Diseases like malaria are returning into areas where they have been extinguished earlier

Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn’t enough information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases. The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings....

Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as other children and are clumsy when they use their hands. There are other long-term effects of pollution. If the gases in the atmosphere continue to increase, the earth’s climate may become warmer. A lot of the ice near the poles may melt and may cause serious floods.

Scientists have long struggled with how to measure the effects of climate change on wildlife. This is especially true for birds flying in and out of coastal areas bordering the Arctic Ocean. In the past, researchers depended mainly on information gathered by satellite to follow the movement of birds and animals. But this method can be costly and result in huge amounts of information, which can be difficult to process.Now scientists are turning to another kind of technology to help them follow...

Scientists have long struggled with how to measure the effects of climate change on wildlife. This is especially true for birds flying in and out of coastal areas bordering the Arctic Ocean. In the past, researchers depended mainly on information gathered by satellite to follow the movement of birds and animals. But this method can be costly and result in huge amounts of information, which can be difficult to process.

Now scientists are turning to another kind of technology to help them follow birds and other wildlife. Songbirds are especially difficult to study in the wild. They can fly across thousands of kilometers and their bodies are too small for electronic tracking devices.

A new report tells about a project in which researchers recorded songbirds and then put the sounds into a computer program to be studied. The researchers created machine learning algorithms with the ability to focus on bird calls while ignoring other noises. The algorithm helps improve the likelihood of predicting the correct result. Similar machine learning methods have been used to recognize human speech.

Các nhà khoa học từ lâu đã phải vật lộn với cách đo lường tác động của biến đổi khí hậu đối với động vật hoang dã. Điều này đặc biệt đúng đối với các loài chim bay vào và ra khỏi các khu vực ven biển giáp với Bắc Băng Dương. Trong quá khứ, các nhà nghiên cứu phụ thuộc chủ yếu vào thông tin thu thập bởi vệ tinh để theo dõi sự di chuyển của chim và động vật. Nhưng phương pháp này có thể tốn kém và dẫn đến lượng thông tin khổng lồ, có thể khó xử lý. Bây giờ các nhà khoa học đang chuyển sang một loại công nghệ khác để giúp họ theo dõi chim và động vật hoang dã khác. Songbirds đặc biệt khó học trong tự nhiên. Họ có thể bay qua hàng ngàn cây số và cơ thể của họ quá nhỏ cho các thiết bị theo dõi điện tử. Một báo cáo mới cho biết về một dự án trong đó các nhà nghiên cứu ghi nhận loài chim biết hót và sau đó đưa âm thanh vào một chương trình máy tính để nghiên cứu. Các nhà nghiên cứu đã tạo ra các thuật toán học máy với khả năng tập trung vào các cuộc gọi chim trong khi bỏ qua các tiếng ồn khác. Thuật toán giúp cải thiện khả năng dự đoán kết quả chính xác. Các phương pháp học máy tương tự đã được sử dụng để nhận ra lời nói của con người.
