Response - Our Iceberg is Melting

John Kotter's change management fable Our Iceberg is Melting is a fascinating read, not just because of its interesting surface story (that of penguins attempting to alert other penguins of the fate that might befall their iceberg), but of the allegory for dealing with change that the book provides. The premise of the book is simple enough, as Kotter himself introduces the book like a fairy tale: "Once upon a time a colony of penguins was living in the frozen Antarctic on an iceberg near what we call today Cape Washington" (Kotter). As one penguin, Fred, starts to notice that their iceberg is ...

Article #1:

The article focussed on the breeding behaviours of emperor penguins that are recently discovered with the help of satellites. Mostly it is believed that penguins lay their eggs on sea ice that is fast and stable and that remains intact under the chick fledge. Fretwell and co-workers conducted this study on forty-six colonies emperor penguins. The recent observation revealed that few colonies of emperor penguins breed on ice-shelves instead of sea ice. Due to rapid climate changes and the incidence of ice melting the penguin population has declined and very close to extinction. It is a big concern that ...

1.0 introduction
Thermoregulation is basically temperature regulation. It is a homeostatic process where by the internal temperature of an organism is kept constant within a specific range despite fluctuations in the external temperatures. It is important to note that all homeostatic systems use negative feedback mechanism. This implies that whenever there is a change in external or surrounding temperature of an organism, consequently a corrective mechanism is initiated within or without the organism to counter the change. Not all animals can maintain a constant body temperature; this is possible only for birds and mammals. Such animals are referred to as endotherms or commonly ...

- The exposure of CFCs to strong ultra violet radiation breaks them down. Whenever this occurs, the chlorofluorocarbon molecule produces atomic chlorine. Just one chlorine atom destroys over a hundred thousand ozone molecules. The overall effect is to wipe out ozone at a faster rate than naturally created (Abdul-Wahab 9).

- Penguins and marine ecosystems are sustained by the energy flow from primary producers in the food chain via intermediate consumers, consumers as well as pathogens, and then back through decomposition pathways (Prischmann 23). Therefore, marine lives are biological networks where the success of penguins is connected directly or indirectly via various ...

Climate change can be defined as changes in weather patterns over time. This time can span up to millions of years (Gillard, 12). These changes are caused by biotic processes and solar radiation variation which the earth receives. Other causes of climatic change are volcanic eruptions and plate tectonics. Human activities can also cause climatic change. Nevertheless, in modern times, climate change has come to be known as ‘Global Warming’.
The first website, http://www.ucsusa.org/global_warming/, talks about levels of sea rises. It also goes to explain large wild fires as causes and consequences of global warming. This website gives the ...

SeaWorld Adventure Parks (SeaWorld) is a chain of oceanariums, marine mammal parks and animal theme parks in the United States. The first SeaWorld Park was opened in San Diego in 1964 and since then, more than 100 million people have visited the famous parks (Malloy). SeaWorld currently operates parks in California, Orlando, San Antonio, Texas and Florida in United States with the three main parks located in San Diego, Orlando and San Antonio.

The experience of being at SeaWorld is breathtaking. Gigantic water-filled tanks, the numerous monstrous sea mammals, spectacular underground exhibitions and the constant water splashing conjure feelings of ...
