Cause and Effect
Cause and Effect organization first gives you the overall situation and then tells you what happens as a result. Since the pamphlet is listing the consequences of climate change, it is giving information about what happens as a result of climate change - the effects. The climate changing would be the cause of the effects.
A problem-solution organizational structure would offer a solution to the problem, but the information contained in the question doesn't indicate that there is any solution in the pamphlet.
Topical organization is more about the information being sorted into different categories. This type of organization is basically used when no other structure fits.
Spatial organization goes in the order in which things are placed. Think first, next, last as transition words for this structure.
