Our view on the graph was that, the information was very small and did not involve sufficient substance to back it up. global warming could be man made or it could happen, so I feel that this graph in my opinion will have no effect on the way we conduct our lives. Computers can cause more co2 than a car, meaning that even if we try to save and be more considerate on green pollution, we will still be polluting via mobile phones and new technology.

3. Our group belives that the reduction of CO2 is not the only factor that will change the results of emissions and people need to focus on factors and make reliable preictions. There are other emissions such as the GHG emmisions and these generate costs globally and this will reduce economic growth. As the climate is changing and getting warmer there are things being put into effect such as air conditioning and shipping of natural disasters; if these were not acted upon this could cause problems.

The hockey stick shows that over the past 900 the climate temperatures have been quite low and have also been stable but data accuracy is quite relaxed and this is a criticism of the hockey stick. It shows an average temperature and the climate is getting warnmer, there are two views; 1 says its because of human activity and 2 that it is a natural process.

Our group think its because of human activity as global warming impacts this and causes the emmissions. the hockey stick is a good scientific method to show the climate temperature apart from the critics of the accuracy.

We need to not just focus our efforts on CO2 but need to worry about other green house gasses. These other gasses have just a big of an effect on the enviroment. Thats what that PDF says.

Political polarisation is an issue, with various governmental nations such as the UK accused of pushing unpopular methods of reducing CO2 emissions like ‘eco-taxes’, with the main argument from eco groups being that it’s an extra way of raising tax revenue.

Climate change is based on human and cooperate activity, each generating a large amount of carbon emissions. Reducing green house gases is expensive, and can effect economic growth as focus on cutting costs in such countries as America or china will reduce their economic growth as R and D will be towards science and technology to reduce these gases. America and china would support non market policies, as no changes would necessarily as they are financially sustainable to afford to buy trade emission credits. Where as in a market based policies, time and money would have to be spent on the technology to reduce the gases, yet large wealthy countries could also afford the eco taxes placed if they were to go over their limits and many would pass on such taxes to their customers.

Mini-case 10.2 Focusing on trying to reduce the CO2 emissions will not have the desired outcome because of the complexity of the systems. Reducing the emissions is a great cost to America and will reduce the growth in China and India. UK accused of using eco taxes as a way of gaining extra income and schemes are highly unpopular. The Hockey Stick Graph The blade increasing coincides with the industrial revolution. The records go way back despite no actual data from the before the 1800’s.

The world economy and financial collapse of 2008 was blamed on greedy bankers and the failure of national and international financial regulation. The argument remains that antropogenic global warming is the most probable possibility. Some scientists state that focussing on the Co2 issues of reduction will not necessarily produce the desired results.



We believe that the scientists hockey stick graph theory is correct when saying that “even if more data was collected, they would be surprised if the graph changed by a lot. “ This could have negative implications for businesses if the planet was to be warming and could effect many areas. Due to rising sea levels and different temperatures through different seasons things such as resources will be effected mainly.

8. Following the economic crash in 2008. There was major debate over C02 emissions with scientists believing human activity is the main factor of global warming. The issues surrounding global warming are very difficult and controversial between countries. This pressure makes it hard for policy makers to decide on a long term solution for the problem, with added pressure of the issue of resources such as; oil, food and water.

The Hockey Stick Graph has been redone many times since the original. And, while the revisions now show a couple of periods of warming, nothing approachs the warming that we are seeing at present. The National Academy of Sciences did a study of the Mann's methods and statistical analyisis. Using their own and his data, and their own statistical methods, their graph said the same as Mann's original one. In fact, that is the case for every honest study that has been done on that graph.
