Future or not for some!: Topic 6 The issue of global warming

May be with rain falling and cool weather in most of the Northern Hemisphere this summer it becomes easy to dismiss climate change and global warming. However if you live on a pacific atoll like Tuvalu then you live the real problems possibly every day. The Guardia and the BBC have both just run interesting stories about what life is like on this remote island with the fear of climate change a part of daily life, especially when in the grip of a drought that has run for over a year. Imagine only having enough water to just about cook with only a teacup full left over for washing or being the hospital administration that might have to deal with a break out of dysentery . Certainly a very useful case when teaching the topic but maybe more useful when making links back to ToK – the ESS Guide states that the “topic directly and usefully challenges popular views of certainty within the sciences.” but how do you get your knowledge over when you are an tiny population with little wealth and few material resources compared to the big countries?

Topic 6: What do we really know about our climate?

Agulhas systemTeaching ESS in Europe means that when you get to the part of the course dealing with climate change you inevitably have to menton the breakdown of the Gulf stream and Atlantic conveyor. But some recent findings bring back the stark reality that often even in ESS we tend to deal with concepts in discrete little pockets rather than taking a systemal approach at looking at the bigger picture.

The recent finding are from an internnational team of oceanographers monitoring the behaviour of the Agulhas system, a current moving warm waters around the Indian Ocean. So what ha this current got to do with the Gulf Stream? The Agulhas system also impinges upon the Southern Atlantic bring warm waters around the tip of South Africa. The team have suggested from models that as the Gulf Stream weakens this flow increases and can in part make up the differences.

Environmental Impact Assessment

Teaching EIA theory is possibly one of the hardest parts of the ESS course if you don’t have a background in it. There are very few really good resources aimed at the level of the Diploma. However UNESCO have a video which asks the question as to if there is merit in an EIA system. In parts it is quite heavy but used in sections can add some real incite into the EIA process

Topic 6: Climate change – a useful resource

The Guardian newspapers online section has just published a really useful Ultimate Climate Change Faq. Lots of information but also lots of useful data such as which industries emit the most Carbon. Could be the source of a few case studies and data research projects.

4.3 Conservation of biodiversity – All wrong about Panda’s

A very interesting article in the Biological letters of the Royal Society, suggest that the world and his dog have been getting the conservation strategy wrong for Giant Panda’s. While we all know about bamboo and the Giant Panda it now appears that Old Growth Forest may be equally as important a habitat for the Giant Panda

It seems scientists may have been concentrating their research to narrowly.
