ae.09 Climate change and the Himalaya

Content

  • Statement of inquiry
    • Scientific and technical innovators need to understand how power affects the processes that occur within systems.
  • Factual questions [Remembering facts and topics]
    • What is the impact of climate change upon alpine glaciers focused upon the Hindu Kush Himalayan region and the associated river basins.
  • Aims of this lesson
    • To examine the impact of climate change upon alpine glaciers in the Hindu Kush Himalayan region.
    • To examine the likely impacts of receding alpine glaciers in the Hindu Kush Himalayan region upon the associated river basins and the populations that live within them.

Task

The end-point will be the additional to your (on-going) notes document of figures 1 to 5 (below) with a short paragraph of text (for each figure) that gives the figure context.

Your short paragraph should try and answer the following →

  • Describe what the figure shows - remembering to use 'Oh so easy' → something obvious, something specific and something odd.
  • Outline the link(s) between what the figure shows and the impacts of climate change upon alpine glaciers in the Hindu Kush Himalayan region.
  • Explain the link(s) between climate change, the impacts of climate change upon alpine glaciers in the Hindu Kush Himalayan region and the population that live in the related drainage basins.

The sources of information you will need to use are below. Start at the top of the list and work through at least the first two sources.

Glacier area change rates (%/yr) for different regions in the extended HKH.
Figure 4 - Glacier area change rates (%/yr) for different regions in the extended HKH. Pre-2000 and post-2000 means are given by the colour in the left and right half-circles, respectively, together with the number of studies available for each period. Circle diameter is scaled to the current glacierized area in each region. A histogram of all observed change rates is given in the upper right. [Source]
