. INTRODUCTION 1.1. What is the Greenhouse Effect? The Earth’s climate is determined by the receipt and distribution of the radiation received from the sun (Dunne, 2013). Light from the sun undertakes three corridors: 25% is absorbed by the atmosphere, 30% is reflected back into space and 45% is absorbed by the Earth’s surface (Dunne, 2013). The light absorbed by the Earth’s surface is converted into energy and used for the various biological processes. In the atmosphere, some gases have strong infrared
Thesis: Both human actions and natural disasters are causes of global warming and the deterioration of earth. I. Topic Sentence: The earth provides protection against the danger of radiation from the sun, but the human expansion of the greenhouse effect results in global warming. A. Claim- My first photo is of earth as seen from space with the focus of the picture on North and South America, and my second photo shows two polar bears in the Artic. Evidence- The second picture depicts two healthy
Task 1 Can polar bears and people coexist? Polar bears are the largest land predator on earth today. They live in the Arctic area, surrounded by the northern nations like Norway, Greenland and Canada. The effects of global warming have caused the temperatures to rise, which have led the Arctic ice to melt. Because the polar bears’ territory is shrinking, they are forced to hunt further inland. They usually hunt on the sea ice, but they cannot do that now. A polar bear can starve for months, but
differ from country to country, with a rise in temperature globally, different countries suffer different effects. For example, recent climate change has caused heat waves in certain countries and an abundance of rain in others. MORE INTRO Key questions How do we know climate change is happening? Earth’s climate has been evolving and changing
disastrous effects it would have onto the world. Today, these two complications are definitely evident and observable in people’s lives. Due to climate change, the Earth’s temperature has increased so much that it has caused sea levels to rise, heatwaves, and agricultural damage in many countries. However, what in fact has been the cause of all this climate change and global warming? They are the greenhouse gases
the average temperature of the earth and its oceans; it is an adaptation that is believed to be permanently changing the earth's climate. Scientists are trying to tell us that the planet is warming. The increased amount of carbon dioxide and other greenhouse gases released by the burning of fuels, agriculture, and other activities, are considered to be the foremost sources of the global warming that has occurred over the past decades. In the long run, we forgot to look after our nature, on which we
explained that by receiving warmth from the Sun, Earth sustains its life and greatly impacted human civilization. This is known as “natural” greenhouse effect which increases the temperature and keeps Earth habitable. Greenhouse effect is a process where the solar radiation is absorbed by the Earth’s surface and some of the heat is trapped by the greenhouse gases in the atmosphere (Kandel, 1990). It plays a vital role in the Earth’s climate which means the temperature of the Earth is changing with
There are numerous elements to the enhanced greenhouse effect. The causes are divided into two categories, the addition of greenhouse gases to the atmosphere and the reduction of carbon sinks. Both of these are caused by human over-consumption, such as combustion of fossil fuels, and mass farming. The greenhouse gases cause global warming and this can have many disastrous effects to the climate and natural life cycles. Global warming is a much debated issue. Many scientists believe it to be a caused
ice snow ice and the rise of sea-level are the effect of climate change. The most common factor that contributes to climate change is greenhouse effect. Greenhouse effect is a process where the solar radiation is absorbed by the Earth’s surface and some of the heat is trap by the greenhouse gases in the atmosphere (Kandel, 1990). This phenomenon has warm and increase the temperature of the Earth’s surface. There is 5 steps how the greenhouse effect happen which are solar radiation passes through
referred to as global warming refers to changes in average surface temperatures on earth. Scientifically climate change is due 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 have a range of effects on ecosystems, including rising sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires. Climate change is now affecting every community on every continent
