Chances of flooding in Bangladesh's near future

This is an image illustrating one of the many dangers that global warming will soon cause.

Responses to climate change, from a local to a global scale.

Here is the link to the Google Pres.

Your task is to create a web site to show the local, national and global responses to Global Warming.

Bangladesh Poverty and affected areas

As you can see where there is extreme poverty and lowland is the exact location that is affected by floods and tidal surges.

Problems caused by climate change for Bangladesh

Climatic change and Bangladesh.

Thanks Karan for letting me see the presentation for the lesson I think students are really going to enjoy this and find it beneficial. For the other students I suspect Karan is going to ask you to find photographs to support his presentation I'm sure he will share his presentation with us on Google docs.   Please say thanks to him as he's worked very hard for you on this presentation.

Here is a great chance to watch it before the lesson and have your questions ready.

Add your questions to the comment section of this house and we will answer them in class.

Karan has kindly said I can post the feedback about his presentation so here it is just click on the link to hear.

Here is his presentation as well. 

Using fig 8 page 36 describe the sea level rise between 2000 and 2100.  Talk about the three scenarios use data in you answer (4 marks).

Once you are done please grade 2 other students answers.

The negative effects of climate change on people and the environment.

Please add you notes and comments here about todays lesson.

Check out this Google Pres.

Farting Cow

The causes of current climate change on a local and global scale.

Methane 

•  Find a picture of a farting cow, and explain how this effects on the atmosphere

• What is Methane?

• What is permafrost?

 Carbon Dioxide 

•Go to Page 33 in your blue textbook, look at fig.4 and describe rate of increase of carbon dioxide levels

Do rich people produce more greenhouse gases?

Do you think humans cause global warming or is this a myth? Give reasons for and against humans causing global warming, think about local and global scale factors. Reply as comments.

Changes in solar output (Rey)

http://www.skepticalscience.com/solar-activity-sunspots-global-warming-basic.htmSolar output is the climate change. For the last 35 years the sun has been cooling down. But the global temperature is rising. Since it’s doing opposite, scientist think that the warming up of the sun is not only the reason for global warming. The sun has a 11 years cycle and causes 0.1% different types to it’s output.

How and Why climate has changed since the last Ice Age

There are factors that need to be taken into account when looking at global climate change besides human impact such as: The earth's orbit, the output of the sun, or catastrophic events in the past.

   Changes in the Earth's orbital geometry
There can be an increase in the earth's temperature by up to 1% if the tilt of the earth, the amount it wobbles and the different angles of the orbit. This is what may have caused the ice ages in the past.

    Changes in solar output
the sun changes its solar output, however slightly, still affecting the Earth's temperature slightly. This can increase or decrease the earth's temperature.

     Catastrophic events
There are catastrophic events in the world such as volcanic eruptions or meteor showers which crash to the earth causing temperature increases. These catastrophic events have also lead to believe to the extinction of prehistoric animals such as dinosaurs. One of these volcanic eruptions occurred in Iceland causing the largest lava waves in thousands of years in addition to millions of tonnes poisonous gas being released.
