I have had several conversations with students recently about anthropogenic climate change. The DIS1 and 2 students are introduced to the concept when they study the Carbon cycle, the DIS4 students study it as part of the Ecology topic when we looked to answer the question “how do you form an opinion” and it was also covered in DIS4 in World studies. The one question that students always ask is the one in the title of this post.
If you are genuinely interested in investing some of your time to raise awareness of this issue and to effect positive change (remember the precautionary principle means we don’t need to have unequivocal proof before we act) there are many non-governmental organisations which are looking to raise awareness amongst the general public, and are looking to put pressure onto governments. Examples are Greenpeace, WWF, 360.ORG and AVAAZ. AVAAZ are running at the moment a campaign,The Global People`s Climate March, on 21st September details of which can be found here.
There are many examples in Scientific history where there has been scientific debate upon important points. One such area is with the theory of anthropogenic climate change. This beggars the question what is a theory, what is an argument, and how much evidence do we need to move from theory to accepted fact. The precautionary principle becomes important here and we will introduce this idea with a discussion of a rather strange art piece from the 1970`s!
Check out the video below for an introduction
A nice learning resource is given here which covers the main areas of this topic.http://i-biology.net/ibdpbio/05-ecology-and-evolution/the-greenhouse-effect/

Remember what we have said previously about how we learn. Little and often is better than trying to cram huge chunks of work at a single sitting.
Remember also the importance of exercise for growing new neurones and making the existing ones work better which we discussed after the crosslauf last year. Finally don’t forget the importance of sleep, see the following article for why sleep is important. http://www.bbc.co.uk/schools/parents/sleep_matters/
I said at the start of the year that previous IB students have said about the IB, “SLEEP, SOCIAL LIFE, SUCCESS AT IB, CHOOSE ANY TWO”! I know it is difficult to manage the demands placed upon your time, but the more work you do now the easier it will be next year when you have to write your actual IB examinations.
So can a book change the world? If we were all to write a list of the most influential books ever written I would guess that many of us would include a book by this man
In this topic we will look at the ideas presented in Darwin`s Book “on the origin of the species”, and we will also discuss why it changed our understanding of the world around us. Before we do that we will study the topic of Ecology. To be able to access this section there is a lot of subject specific vocabulary that we need to learn. Here is a vocabulary sheet for you to learn. We will test your understanding of this vocab in a small quiz on Monday.
To get us in the correct frame of mind we will look at this TED talk. As our species becomes more successful our effect upon the ecology of our planet becomes increasingly large. Is this a good thing?
We will also see what Hank has to say about Ecology when we look at
