Climate change – a critical emerging issue

Abstract

Science on observed trends in climate and projected future climate change has evolved substantially in the last few years. Different sub-regions of South Africa have shown, and are likely to continue to show, distinct climate changes. Surface air temperature has increased significantly over the past thirty years at least, and is projected to further increase into the 21st century. It is essential to note that South Africa has existing critical vulnerabilities that will exacerbate the effects of climate change in most sectors, and compromise effective responses if inappropriately managed. In terms of policy and response, most sectors in South Africa could benefit from the ‘multiple benefits’ strategic planning approach mentioned above, with particular attention paid to cross-sectoral strategies (for example, water, invasive alien species and fire management). The role of the National Planning Commission is critical here in ensuring that departments are monitored not only on their sectoral response, but on their coordination with other departments in responding to climate change.
