I have mentioned to friends & family and maybe even in here but I am not sure if I did. I have felt that global warming will affect us sooner than we think & sea level rise will be a huge issue for Florida especially when the majors start whipping through here. Meanwhile ocean property management blames erosion from winds as the problem as to why our beaches are dissapearing. I also feel that seeing snow in the lower 48 will be a thing of the past within 50 years. --Previous Message-- : Nice report Target.
