Imagination and vivid wording to captivate the reader.
- The topic sentence is: Climate change and renewable energy sources.
- In the second paragraph, a change of focus (in point of view) on renewable energy sources has been used.
Paragraph 1: Climate change impacts pose a global threat since a report carried out by the IPCC (Intergovernmental Panel on Climate Change) warns that global warming may be irreversible. The importance of renewable energy solutions in mitigating climate change has been proven: the actual dependence on fossil fuel energy sources highly contributes to global greenhouse gas emissions, the leading cause of global warming.
Paragraph 2: However, <em>such</em> alternative energy sources, because of their intermittency, (in the sense that, for instance, the wind doesn't always blow nor does the sun always shine) can’t be that efficient. Therefore, world leaders should join efforts to set up enhanced environmental policies so as to tackle global warming consequences.
I tried and tried to understand the problem. this phrase is a prepositional phase se one is telling something
