Globally, the winter of 2014–15 was the warmest winter on record at that time, but it sure didn’t seem that way for most of the eastern united states. this region experienced record-low temperatures and extreme snowfall, especially in the northern and coastal areas. during this period of extreme cold and snow, it was not uncommon to see comments on social media disputing climate change. for example, some commenters took pictures of huge piles of snow and added comments such as, "this doesn’t look like global warming." do these commenters have a point? should extreme snowfall over the course of a season cast doubt on the theory of global climate change? make a scientific argument explaining why you agree or disagree with these commenters.

Where does all the water go? according to the environmental protection agency (epa), in a typical wetland environment, 39% of the water is outflow; 46% is seepage; 7% evaporates; and 8% remains as water volume in the ecosystem (reference: united states environmental protection agency case studies report 832-r-93-005). chloride compounds as residuals from residential areas are a problem for wetlands. suppose that in a particular wetland environment the following concentrations (mg/l) of chloride compounds were found: outflow, 60.4; seepage, 73.7; remaining due to evaporation, 26.4; in the water volume, 46.8. (a) compute the weighted average of chlorine compound concentration (mg/l) for this ecological system. (round your answer to one decimal place.) mg/l (b) suppose the epa has established an average chlorine compound concentration target of no more than 58 mg/l. does this wetlands system meet the target standard for chlorine compound concentration? yes. the average chlorine compound concentration (mg/l) is too high. yes. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is lower than the target. no. the average chlorine compound concentration (mg/l) is too high.
