Figure:CO₂ emissions for selected countries in 2007 and projected for 2030
There are concerns that increased carbon dioxide ( CO2 ) emissions are leading to changes in the global climate.
Explain how the ability to implement mitigation and adaptation strategies may vary from one country to another.
political will/pressure for change may differ due to some countries being more/less committed to their industrial lifestyles/economic growth / inhibited through political corruption; finance/economics may/may not allow some countries to fund new technologies/infrastructures; some countries may depend upon others for knowledge transfer/technological assistance to implement resolutions; religious/political/cultural norms/education in some countries may promote/limit their perception of environmental threats/approach to management; geographical location of some countries may place them at greater/more immediate risk from impacts of climate change (eg low-lying islands/tropical storm-prone nations) / or offer them greater opportunities for mitigation (eg available sources of alternative energy); some countries may perceive greater immediate priorities eg war in Syria/poverty in Somalia;
