Final answer:
An essay on climate change should address the consequences of greenhouse gas emissions, refute objections, and propose solutions to mitigate the effects.
Step-by-step explanation:
The topic of climate change is vast and can be approached from many angles in an essay. To define it more narrowly, one might concentrate on the effects that greenhouse gas emissions and carbon sequestration imbalances have on global warming. In the body of the essay, addressing objections is key, as it strengthens the argument by considering and refuting opposing views. The essay could also incorporate how natural systems have been disrupted by human activities, resulting in increased emissions that accelerate climate change. Moreover, the dire consequences such as rising sea levels, stronger storms, and the advent of climate refugees underline the urgency of the matter. Reflecting on the problem and solutions, like those proposed by student Shawn Krukowski in his piece 'Slowing Climate Change', provides a blueprint for tackling this challenge through meaningful proposals.
