  7. …until people like you make products like these…

  8. …and these.

  9. Empowered to develop plans to warn proactively… • The drainage basin • descriptions, facilities, hydrology, flood history, problem areas, flood routing/timing • Decision aids • ALERT system, flash flood guidance, inundation areas • Communications • Meteorological support • National Weather Service • Private Meteorologist • Flood threat recognition and warning process • Procedures and general responsibilities • Public dissemination • Media contacts • Annual revisions and practices

  10. …and practice those plans.

  18. AMS Statement onClimate Change Final remarksDespite the uncertainties noted above, there is adequate evidence from observations and interpretations of climate simulations to conclude that the atmosphere, ocean, and land surface are warming; that humans have significantly contributed to this change; and that further climate change will continue to have important impacts on human societies, on economies, on ecosystems, and on wildlife through the 21st century and beyond. Focusing on the next 30 years, convergence among emission scenarios and model results suggest strongly that increasing air temperatures will reduce snowpack, shift snowmelt timing, reduce crop production and rangeland fertility, and cause continued melting of the ice caps and sea level rise. Important goals for future work include the need to understand the relation of climate at the state and regional level to the patterns of global climate andto reverse the decline in observational networks that are so critical to accurate climate monitoring and prediction.Policy choices in the near future will determine the extent of the impacts of climate change. Policy decisions are seldom made in a context of absolute certainty. Some continued climate change is inevitable, and the policy debate should also consider the best ways to adapt to climate change. Prudence dictates extreme care in managing our relationship with the only planet known to be capable of sustaining human life.
