Global warming is a war that we should not get involved with because we will lose if changes aren’t made soon. Global warming is the rapid increase in earth’s average surface temperature over the past century due to the fact that greenhouse gases are being released into the atmosphere increasing the earth’s average temperature (EarthObservatory.NASA.org). There are many contributing factors that play a role into the cause of global warming. Greenhouse gasses are gasses such as Carbon Dioxide, Methane, Nitrous Oxide, and F-gasses that trap heat in the atmosphere. The heat that is trapped in the earth’s atmosphere is a slowly melting glaciers, cause sea levels to rise and is messing with the weather patterns.
One of the major problem that global warming is causing is the melting of sea ice in the arctic. Due to the melting of the sea ice, global temperature suffers. In order to stop the global climate change, the congressional committee on environment must pass a legislation to regulate the use of fossil fuels, because climate change in the arctic is causing all the ice to melt, the permafrost to thaw, and it has huge impact on the vegetation and the wildlife. Over the years the loss of extensive amount of ice serves as the evidence that, arctic is in fact warming faster than any other region on the earth. According to NSIDC, March 2015 ice extension is recorded at average 14.39 million square kilometers.
Glaciers are melting up which results in the rise of sea level, oceans are turning more acidic. These climatic changes shall throw more challenges to our environment. Greenhouse effect and Greenhouse gases: Earth absorbs lot of energy from sun and gets warmth during the day. It gets cooled down by releasing infrared radiations. But the greenhouse gases do not let the infra-red radiations escape into the outer space.

It will also cause less oxygen in the deep ocean causing death of sea species. Moreover, it will make changes in the weather conditions of earth. According to my point of view, the scientists should research and measure the changes of the climate and the global warming it is causing. Benefits and harms should be measured before making any conclusion.
Sun is the ultimate source of heat energy which fuelling the weather systems after reaching to the earth. Earlier the harsh and extended bitter cold season was called as the little ice age which was due to the huge level variations in the solar activity. It is found that the positive human activities may play major roles in shaping earth’s climate. Such a huge variations in the climate may lead to the danger of the human lives. Earlier it was believed that shifts in the climate pattern from ice age to warmer periods was because of time however later it was imagined that it is due to regular melting of ice sheets of more than a kilometer in thickness.
Introduction: Climate Change ‘Sustainable development is a process of building and maintaining human health and well-being within established biophysical planetary boundaries’ (Kates 2010). Currently a significant problem on earth, and a major issue in sustainable development, is climate change. Climate change can be defined as ‘Any change in global temperatures and precipitation over time due to natural variability or to human activity.’ (Mcgraw-Hill 2003). It is however specifically the impact of human activity that is of concern as the increased burning of fossil fuels and production of greenhouse gasses has caused an increase in global temperatures over the last 200 years to skyrocket. This is causing polar ice caps to melt and a rise in sea levels, which in turn will cause flooding of low-lying land.
The following diagram represents the effect of greenhouse gas emissions on the oceans causing increased CO2, decreased pH, sea level rise, storm frequency and potential upwelling. Due to the rapid changes in comparison to previous years, fish are becoming prone to predator attacks and are having difficulty reproducing due to higher acidity levels. Because of increase greenhouse gas emissions carbon dioxide absorbed within the Earth’s atmosphere this excess CO2 prevents heat from escaping the planet, this process is known as the ‘greenhouse’ effect which is the cause of global warming. upwelling is uncertain. 3.2 Temperature change and Rising Sea levels... ... middle of paper ... ... many of these species are more vulnerable to increased fishing pressure than climate change (Graham et al.
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.
2.1Thermal expansion As seawater becomes warmer it expands. Heat in the upper layer of the ocean is released quickly into the atmosphere. However, heat absorbed by the deeper layers of the ocean will take much longer to be released and therefore, be stored in the ocean much longer and have significant impacts on future ocean warming. 2.2 Melting of glaciers and polar ice caps: Large ice formations, like glaciers and the polar ice caps, naturally melt back a bit each summer. But in the winter, snows, made primarily from evaporated seawater, are generally sufficient to balance out the melting.
In recent years, global warming is a topic that has received much attention. It’s is a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide and other pollutants, which also known as the green house effect. Global warming can negatively affect the earth's delicate ecosystems. It has been linked to dangerous new weather patterns, the extinction of plant and animal species and so many others bad effects. Global warming is caused by pollution eating away at the ozone layer of the atmosphere, as well as greenhouse gases trapping heat.
