Why is there such concern about the threat posed by anthropogenic climate change? Review the arguments for and against.
There is such concern about the threat posed by anthropogenic climate change because of the affects it has on land surfaces, oceans and the ozone layer. The depletion of the concentrated ozone layer in the stratosphere is a big concern as it is believed to be cause by gas emissions which include, methane, carbon dioxide, chlorofluorocarbons and many more (Middleton, 2013). The levels of the input of these gases have been rising, for example carbon dioxide levels have increased by 21.25% from 1958 to 2013 (Cunningham and Cunningham, 2015).The effect of this results in an increase in solar ultra violet radiation reaching the earth as the ozone layer has the capability …show more content…
Whilst other scientists argue that climate models are unreliable, they have been useful to give a fairly accurate representation on what climate change is doing to the earth. The Intergovernmental Panel on Climate Change (IPCC) tested detailed models against the observed trends of world temperatures. The results showed that the only way to explain increases in air temps, ocean temps, declining snow and ice cover were the models with human caused changes as the models without human input were much lower than observed climate records (Cunningham and Cunningham, 2015). If people continue to ignore the climate change and ignore that global warming exists it will have severe consequences. Climate change will cost more than prevention and according to Sir Nicholas Stern, a former chief economist of the world bank, the damage of climate change could cost 20% of the annual global economy if no action is taken soon the prevent the serious threat up (Cunningham and Cunningham,
