Question

Question restatement: Global sea level rise is anticipated to increase between ___________ by the year 2100.

Option 1: '1-4 millimeters' — This is far too small to align with climate science projections. Even conservative estimates for 2100 exceed a few centimeters, let alone millimeters, so this range underestimates the expected rise.

Option 2: '1-4 meters' — A rise of up to four meters would be unprecedented in most mainstream projections and would imply dramatic, unlikely changes on a global scale within this century. While some high-end scenarios exist, this range is generally considered outside the most commonly cited consensus ranges for 2100.

Option 3: '1-4 centimeters' — This would correspond to 0.01 to 0.04 meters, which is well below the projections described by climate assessments that anticipate more substantial increases by 2100. Therefore, this option is too small.

Option 4: '1-4 feet' — This aligns with several widely cited projection ranges for 2100, which place sea level rise somewhere in the vicinity of roughly one to several feet depending on emission scenarios and ice dynamics. This option reflects the commonly discussed scale of change rather than an order of magnitude smaller or larger.

Summary: The analysis of the first three options shows they are either far too small or implausibly large relative to established projections, while the fourth option matches the commonly referenced range for 2100. The reasoning hinges on comparing unit scales (millimeters, centimeters, meters) to credible climate projections that anticipate increases on the order of feet rather than millimeters, centimeters, or meters alone.
