Introduction Climate change has become a major concern in recent decades. The global warming has caused the raise of sea level and extinction of some species. Reducing greenhouse gas emission has become a primary role of solving this question. Under rapid developing era as nowadays, environment also deteriorates at a worrying speed. Some developed countries realize that environmental protection actions need to be taken to prevent the possible catastrophic climate change on the planet, however, federal government of Canada do not take any action about the climate change.
While the increasing temperature around the Arctic is threatening the existence of marine mammals and the condition of the ecosystem, melting of the ice around that region may affect the temperature of the globe. Global warming is one of the emerging issues currently experienced in the world. The melting of the snow in the Arctic is among the effects of global warming and thus is used to prove the intensity of the earth’s warming process. The Yenisey and Lena rivers of Siberia demonstrate one of the deep effects of global warming, which is scientifically termed as heat expanding. This is because they ... ... middle of paper ... ...UN, Canada, Greenland, Norway, and Russia.
These problems include worldwide climates change, which will eventually lead to environmental chaos. These greenhouse effects are especially felt in the Arctic. They trap gases that capture and hold heat in the atmosphere, causing the Arctic to warm up and the ice to melt. Without proper action towards decreasing the effects of global warming, Earth and its inhabitants will face several environmental and security difficulties in the near future. Global warming creates one main problem, which causes several other problems to stem from it.
Over history we see natural stages in our Earth’s climate between warm and cold periods because of increased Carbon Dioxide. These stages are usually cyclic but temperatures are rising faster than ever before (Pipkin). Ancient ice cores dating back 800,000 years show a steady level of greenhouse gasses (Scambos). Proving this point Ted Scambos states: “The dramatic rise in the gasses seen in the past few decades- from 315 parts per billion in 1958 to 388 parts per million for carbon dioxide. .

Since the industrial revolution, scientists have documented a trend of increasing atmospheric carbon dioxide (CO2), the main greenhouse gas. This observation has been an issue of major environmental concern in the view of the potentially devastating effects of climate change on ecosystems and human survival. Recent studies by scientists led by Wei-Jun Cai have served to underscore this fact by showing that the Arctic region and the globe are faced with a major climate challenge due to the continued melting of sea ice in the Arctic Ocean. This research has indicated that the major concern is the increasing heat absorption as deeper ocean water layers get exposed to sunlight as well as the possible loss of white ice reflectivity or the albedo (An Ice-Free Arctic Ocean Will Not Absorb More CO2, n.d).This paper discusses the recent observations that Arctic Ocean basin do not have an indefinite ability to continue acting as a CO2 sink when conditions are ice-free caused by the escalating warmer temperatures. It is worth noting that sensitivity to climate changes in the Arctic is considered the highest on the Earth’s surface.
Introduction The world has been warming up including the arctic since the 1950s (Hudson and Henry 2009; Mcguire et al. 2009).This concept is widely known as climate change or global warming. The increase in temperature on the earth surface and atmosphere has been a by-product of man’s industrialization and an insatiable need for energy (Smith 2008). A once contentious issue has now been put to rest furthermore there is the newly found supposition among the public that in fact climate change is a real and threatening problem (Smith 2008). The arctic’s warming affects a cross spectrum of environmental and biological systems that might not be irreversible and have the potential to cause precipitous changes in the earth structure (Mcguire et al.

Global Environmental change also known as global warming has been a rising concern for a while. The International Panel on Climate Change states that Environmental change is anthropogenic. The World Health organization defines anthropogenic climate change a cause of human and human activity. Major causes of environmental change throughout the world are the increase in Carbon dioxide and greenhouse gases.1 In the past when looking at environmental change the main focus has been on the environment and the ozone layer of the earth, but climate change has a very immense effect on human health. This paper specifically looks at how global environmental change has an effect on the health of people residing in Canada.
