Letter writer Fred Williams, Nov. 3, questions the impact of global warming on hurricanes. However, in its report "Catastrophe Modelling and Climate Change," Lloyd's of London states that the eight inches of sea-level rise off the tip of Manhattan increased Superstorm Sandy’s surge losses by 30 percent, and that "Further increases in sea level in this region may non-linearly increase the loss potential from similar storms.” This document also asserts that there is conclusive evidence that climate change is human-caused.

Moreover, in its 2014 Quadrennial Defense Review, the United States Department of Defense warns, “As greenhouse gas emissions increase, sea levels are rising, average global temperatures are increasing, and severe weather patterns are accelerating. These changes, coupled with other global dynamics … will devastate homes, land and infrastructure.”

It's helpful to look to independent organizations like the insurance industry and the military when evaluating the threat posed by climate change. Because they depend on scientific evidence to assess risk, they are less amenable to politicized science.

It's crucial for Congress to heed these voices and take a leadership role regarding climate action.
