Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006). Warmer temperatures have led to increased melting of glaciers and sea ice, and shortening of
Climate change is more serious than we take it. If it continues, everyone will parish. Climate change affects us in many different ways. It causes animal population numbers to decrease, slows down transportation to the north, and causes flooding and the rise of the sea level. Global warming exists, and it is not only affecting the environment.
The Effects of Climate Change on Canadian Polar Bears Although climate change has had severe impact on the Canadian population, the melting of the Canadian Arctic ice caps has proved to be detrimental to the five subpopulations of polar bears in Canada, which are found in the Arctic Archipelago, Beaufort Sea, Hudson Bay and James Bay region. (Clark). Polar bears are dependent upon sea ice coverage to be consistent, and because of the recent change in climate, they are becoming a more at risk species (Stirling and Parkinson). In The Fourth Assessment Report of the Intergovernmental Panel on Climate Change of the United Nations, they reported that the world climate change will continue to warm, it will only get worse and the primary cause of
Polar Bears are a species that is in decline. They are currently listed as a vulnerable species because of the decline of their population. Climate change is a driving causes in the decline of Polar Bears. According to a study published in Ecological Applications, “Polar bears prefer sea ice concentrations exceeding 50% in the shallow, productive waters over the continental shelf” (634). This sea ice is essential to the Polar Bears because it allows them to feed off of their prey. Unfortunately, the amount of sea ice is beginning to fall, and the number of Polar Bears is falling with it. The cause, climate change, is a controversial issue that needs to be addressed. It will soon cause Polar Bears to become endangered and even
Climate change is the most rising issue of the modern world that is threatening our planet from the last few decades. In the simplest definition, the term climate change refers to the rising of the planet’s temperature, particularly an increase in the average atmospheric temperature. It should be noted that in the last few decades, many scientists and ecologists has discovered the Earth temperature is increasing at an alarming rate and has affected the planet in numerous of way. The constant change in the climate due to various causes is threatening the preservation of the Earth and its human life. It should be noted that the climate change is linked with several of the human activities that are further directed towards the global warming.
Climate change is a huge issue around the world. It is melting the polar ice caps, which is rising the sea level wiping out cities along the coastline. Also because of the ice caps melting many animals that live on it are going extinct. The animals that don’t live on the ice caps are also going extinct because they can’t adapt at the alarming rate that the climate is changing. Some animals are starting their migration earlier and other animals are going to higher elevations (higher than they should) to get cooler weather.
It is evident that most of the gases came from the combustion of fossil fuels from factories, cars, deforestation, gases used for refrigerator among many others by the citizens. The carbon dioxide gas which led to global warming, trapped heat and remained in the atmosphere longer comparatively to other gases. Undeniably, United States was completely responsible for the emission of these
The inuits have a strong bond. They are a big family and work together as a community to have enough supply for the dogs and themselves. The men work. The women stay home with the kids.Every person has their own job. All men work to support their families. The strong bond between the inuits help them support the dogs and the community.
Polar bear endangerment The article “Melting Ice Threatens Polar Bears ' Survival” by Katie Madan is about the melting icebergs and how it is threatening the polar bears survival. The department of interiors are making a decision on putting the polar bears on the endangered species list, a study shows the Polar bears in beau fort sea region in Alaska and Canada are going to go extinct soon. The bears need there ice as a platform to hunt for their food such as seals or fish, if they cant hunt for food then they will die of starvation thus making them extinct. The population of the polar bears having been decreasing by 25 percent per year.
Global warming was significant to the Inuit people since it was easier to receive fresh water. Fresh water was difficult to collect because most of the snow was polluted and unsafe to drink. Also, the purest water was difficult to receive.
These gases retain heat on earth thus increasing the temperature above average. Different gases have dissimilar abilities to trap heat. Deforestation is also another important reason for global warming. Plants release oxygen and take in carbon, thus providing us a clean and healthy environment. But by deforesting the lands, the trees would emit the carbon stored in them from hundreds of years making the air impure.
With deforestation being one of these roles because when we chop down these trees and plants of where animals habitats our it also releases a lot of carbon dioxide into the air. And if you didn’t know forests are major carbon storage centers, when deforestation happens all the carbon dioxide that is stored in these forests; is released back into the atmosphere. Deforestation not only contributes to changes in the climate, it also causes localized changes in the weather. Trees transpire, or release water into the atmosphere, during photosynthesis. This water replenishes clouds and maintains rainfall.
Climate change is a change in global or provincial climate that changes over a time span of many years. Weather can change in just a few hours, But Climate change takes hundreds or even millions of years to change. Climate change is happening all around us. Whether it is the global temperature rise or the melting of the polar ice caps, it is happening.
