Climatic changes
What are some examples of the different ways climate changes has been framed?
Scientists have reported that the use of chlorofluorocarbons (CFCs) destroys the earth’s ozone layer thus allowing harmful ultraviolet rays from the suns to penetrate into the earth.
The other example of the framing of climatic change is that even in the preceding century, the earth had shown signs of climatic change. Greenhouse gases that result from human activity, such as clearing land cover, combustion of fossil fuels, have been blamed to play a major role in bringing about the climatic change.
What informs these different framing?
The CFCs were found to be responsible for the large hole in the ozone that scientists found to be enlarging every year over Antarctica.
This was based on the meteorological history spanning a period o0f 140 years. The meteorological history indicated that the hottest decade was the 1990s and the hottest year in that meteorological history being 1998 and year 2001 slotting into the second position. The World Meteorological Organization reported that the nine hottest years in the recorded history of meteorological happened from the 1990s. Other reports have shown an increment in the sea level by 10-20 cm. snow coverage has been reported to have decreased by about 10% since the 1960s. For the last three decades, there has been reported of adverse El Nino effects in the Southern Hemisphere.

How does the existence of alternative framing affect policy negotiation and debate?
Alternative framing affect policy negotiation and debate in that they give reasons that are not radical. Such an example would be the claim to preserve the tropical rainforests merely because they are a source of medicines, give oxygen or cushion against mudslides. Even though such reasons may positively affect policy negotiation and debate, and to cap it all, as (p.20 Dobson, 1993) note they “lack a sense of impartial, biocentric view in which the non-human world is considered to be of intrinsic value”.
