Polar ice cap

In today’s atmosphere, carbon dioxide (CO2) amounts to 400 parts per million (ppm), but it hasn 't always been that high, or low, depending on what we are comparing it to. It is a trace gas that is vital to Earth’s atmosphere and has been around since the creation of Earth’s first atmosphere, which occurred shortly after the planet’s creation. The advent of Earth’s second atmosphere happened when lighter gases such as hydrogen escaped into space or were bound to molecules, leaving gases like nitrogen

Of all the changes swirling around us, perhaps those that affect the natural environment hold the most serious implications for the future of human life. Scientist are increasingly convinced that we face global warming. They warn us that the polar ice caps may melt and inundate the world’s shorelines, the climate boundaries may move north about four hundred miles, and many animal and plant species may become extinct (Polyakov, 2010). Climate changes refer to balance of energy coming into the Earth

Katherine Suarez Bio. Professor Agostino November, 29 2016 Global Warming/ Climate Change Global warming or also known as climate change refers to the increase heating of Earth 's surface, oceans and atmosphere and its effects. It is unknown who was the first person to point out the term “Global Warming”, but since the late nineteenth century geologist started talking about that increasing carbon dioxide by combustion, which could be the cause of rising temperature. But if talk about 55 million

Earth’s average temperature which causes the melting of the polar ice caps, rising sea levels,longer and more damaging wildfire seasons,more frequent and intense heat waves, heavier precipitation and flooding, decline in the Arctic sea ice extent, widespread retreat of Alpine glaciers,reduced snow cover in the Northern Hemisphere, ocean acidification, ocean temperatures rising and the possible deglacification of the Greenland and West Antarctic ice sheets.

Have you ever wondered why people tell you not to drink water when it is raining outside? Well the answer is simple pollution has affected our water source by ground and in air. This is rain is most likely to be in high population cities called acid rain. This acid rain not just harms people, but also harms animals and plants. According to British Broadcast Company (BBC), In Rio de Janeiro, Brazil, over 50 tons of dead fish were taken from the lagoon the scientist have figured that they fishes were

(people who represent a government, etc.) since Viking 1 landed in 1976. Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be

all over the world due to the ocean currents. Ocean currents can affect places that share the same latitude in Europe and North America. Any of these phenomena can have an impact on the climate, as is believed to have happened at the end of the last Ice – Age, about 14000 years ago. Human Causes Use of Oil, Coal and Natural Gas With the dawn of the Industrial Revolution in the 19th Century, we saw the large-scale use of fossil fuels (such as Oil, Natural Gas, and Coal) for industrial activities

farming of land and animals, building cities, and establishing factories and power plants. Each factor has contributed to the negative impact of the earth’s environment in many different ways. The temperature is beginning to increase; glaciers and polar ice caps are melting, carbon dioxide levels are rising, causing the ozone layer to deplete. As of today, one of the biggest problems not only for human beings but also for this planet is known to be climate change. When greenhouse gases are increased,

“Every cubic inch of space is a miracle.”- Walt Whitman. A big question is floating around the world; is space the answer to the survival of the human race? Astronomers approve this theory and say yes space is the answer to humanity 's survival. This is because the earth is running out of time due to the greenhouse effects. The greenhouse effect is radiation that is emitted by the sun that destroys our atmosphere. Without the atmosphere, there will be no air, and without any air humans and almost

way to the Cretaceous Period. The Cretaceous Period had a similar climate to the Jurassic, warm. The geography, however, was changed a drastic amount from the previous period. The Earth had very high sea levels at this time due to the lack of polar ice caps. The supercontinents Laurasia and Gondwana were breaking apart into the continents that are the same in the present day. Although the continents were the same, they did not yet look exactly the same. The continents will be further shaped by volcanic
