Glaciers have been around for millions of years and with the arrival of global warming there being threatened and challenged by warmer weather conditions and many of them have already melted and this has happened before but there has normally been a ice age and the glaciers just grow back but with the arrival of global warming the chance of a ice age has gotten much smaller and so has the chance of the glaciers that have melted to grow back or for new glaciers to form. For my global perspective I will be looking at the whitechuck glacier in Washington that from about 1970 to 2011 has retreated about 2 km and has lost half it's surface area. For my local perspective I will be doing the fox glacier which in just the last about 25 years has
melted a fair distance about 400 meters is my best estimate and is retreating again and may not slow down or stop. For my national glacier I will be doing the tasman glacier which is melting at a rapid rate now has a large terminal lake in it and may not last much longer. glaciers all over the world are melting or have melted and with the glaciers melting this could be a warning that the arctic or antarctic could melt and that would have disastrous consequences with sea levels rising over 60 meters but everyone thinks the chance of it melting is very small but i bet a few hundred years ago people thought that glaciers wouldn’t melt away and many of them have gone now so who knows what the future could hold if we temperatures and CO2 levels keep rising future generations could be in deep trouble.
The whitechuck glacier which is found in Washington has been retreating rapidly since the end of the "the little ice age" which was a period of colder weather but not a full blown ice a...

...with the tour groups spending so much extra money making it safe the cost of going on this incredible glacier will go up and up until it is not worth going on it and this will impact the tourism and the glacier guides will probably stop and no one will be able to see this glacier which will be such a shame.
for my national case study i will look at the tasman glacier located in mount cook national park and from 1990’s has retreated about 180 meters a year and now is retreating even faster up to 800+ meters a year and won't stay around for much longer, it already has a large terminal lake that in 1973 did not exist but now in 2008 and now has a water volume of 3.4 billion meters cubed which is absolutely huge. the tasman is new zealands longest glacier it is 27 km long is a huge glacier but this does not affect the rate that the glacier is melting and

- What are the risks of climate change and global warming. Climate change is changing our economy, health and communities in a lot of different ways. Scientists have warned us that if we do not do something soon to stop polluting our planet, the results will likely be disastrous. Climate change affects all of us. Global warming can increase the chances of illness and some cases death because of the extreme heat and heat waves. Some people still don’t believe that global warming is real, but because of a lot of studies, that scientist have conducted, we have proof that is it real and we need to do something about it....

- GLOBAL WARMING A huge level climate change in the current time attracts the people’s attention very easily. Every one of us is feeling very clearly from the short-term changes in the seasonal patterns of temperature, drought, rainfall without season, changing weather patterns, etc. to the long-term changes affecting the entire earth. Climate is a long-term weather trend affecting human lives positively or negatively. Climate change is the long term variations in the weather patterns. Climate itself adjusts time to time however going at wrong path since many years because of regular loss of huge ice sheets.... [tags: Global warming, Climate change, Earth]

- There are many things that can impact the economy, but many people would not think that global warming has much of an effect on it. Global warming is continuing to become a very large concern for people across the world. This topic is very controversial due to the fact that many people fail to believe that global warming even exists. In this case, it will often be looked at as climate changes instead. Global warming, or climate change is a gradual increase in average temperature of the Earth’s atmosphere and its’ oceans.... [tags: Global warming, Climate change, Atmosphere]

- There are a variety problems in the world, ranging from starvation and mental illnesses to taxes and military spending. Climate change, a change in global or regional climate patterns, is just one of the major troubles of the Earth. A portion of those patterns includes the weather, ocean, ice/snow, as well as ecosystem patterns. Climate change provides several damaging effects on society and the earth itself including droughts, loss of vegetation, and an increase in natural disasters. Although it is not realized by many, climate change affects all aspects of human life.... [tags: Carbon dioxide, Global warming, Climate change]

One of the most important problems is crucial to focus on and it is climate change or “the greenhouse effect.” The greenhouse effect is a serious problem that is destroying the planet and its atmosphere. Rules and regulations need to be made if want future generations the have a place to call home. What is climate change.... [tags: Global warming, Climate change, Carbon dioxide]

- Outline Climate change is caused due to the release of few carbon compounds into the atmosphere, which drastically brought the weather changes all over the world. Climate change is not confined to a single region. It has become an important issue all over the world for the past few years. Reasons of global climatic change Global warming is one of the major reasons in marine pollution. For an instance in the year 2010 there was an oil leakage near Mumbai in the Arabian Sea. Another reason is deforestation.... [tags: Global warming, Climate change, Carbon dioxide]

- The purpose of this briefing note is to inform newly elected Prime Minister, Justin Trudeau, of the urgency to take action to reduce greenhouse gas emissions. We realize the magnitude of climate change as an issue and must take serious and committed measures if we wish to protect the health of this country and its people. I will propose a specific action plan that will reduce GHGs and create a sustainable and ecologically responsible society. Backround Climate change is the long-term change of the Earth’s climate....

- Many effects of human induced Climate change are poorly understood and the general argument of rising greenhouse gases due to human actions will cause global warming and any other climatic changes on earth. It is said that Australia is the 15th emitter of greenhouse gases and the 18th emitter of Co2 in the world. Australia is already feeling the consequences of more frequent and extreme weather. Australia’s global influence in averting these risks will depend on how effectively we implement policy solutions at home ("Lagging Behind: Australia and the Global Response to Climate Change", 2016)....

- Himalaya, the Third Pole, is nourished with the highest concentration of snow and glaciers outside the Polar Regions (Dyhrenfurth, 1955) and usually known as the freshwater tower of South Asia. In the mountainous regions such as the headwaters of the Ganga, the Brahmaputra and the Indus river, the Himalayan glaciers are important components of water cycle. The Cryosphere of the Himalayan region plays a significant role in the regional climatic system, and is also a sensitive indicator of global climate change (Bajracharya and Shrestha, 2011)....

- Humanity’s Effect on Global Warming and Climate Change Global warming and climate change have been frequent topics of discussion over the past several years. Although people tend to focus on the politics, it is time to look past the media aspects of it and into the cold hard facts of what our Earth is currently experiencing, and what caused it in the first place. The cause of climate change includes natural causes, but human causes are what is generating such a rapid global change. It’s time that the ways in which humanity affects the Earth’s climate, how scientists record and measure the climate change, and what can be done in everyday life to slow it down and/or stop global warming, are...
