They are a fish that really like very clean water so pollution and water quality play a good part in their survival and that can vary creek to creek depending on local conditions (which would be different for almost every creek) Creeks in general will have a similar temperature, but this also can vary depending on the shade covering of the river from trees or topography, but this is usually not much of a difference. In terms of climate the likely biggest effect may be a change in rain fall, which would have an effect on a number of aspects of any creek system lower water levels, slower flow, reduced water quality.
As far as kano's little chant "There is no real man made climate change" and little graphic, this trick works like this, they use one particular data set to generate this graph from a site called woodfortrees, of course there are many data sources and almost all of them actually show a rise in temperature, deniers cherry pick the one that doesn't, deniers further slew the data by picking 1998 or 1997 as the starting point, to give the downward slope to the trend line as there was a massive El Nino in late 97 and into 98, the strongest of the last 100 years. Pick years earlier or later and the trend is a rise.
i.e. 1995 (at the time the warmest year in the modern record)

or 2000 a year without the effect of the strong El Nino

Of course if you look at the full temperature record the fiction of kano's statement is quite obvious

There is no real man made climate change, temperatures have remained steady for many years, https://sp2.yimg.com/ib/th?id=HN.6079872...
Why some creeks (assuming they have similar flow rates and water levels) in the same area should have different trout survivability must be down to water quality, levels of oxygen, PH, nitrites, nitrates and ammonia all affect fish.
One thing is for sure, it is not due to Climate Change. It can't be, since nobody has defined it in a scientific manner. So if someone could define Climate Change scientifically, then we might be able to pin point it.
I suspicion that the higher mortality rate is due more to bacteria than climate.
Consider:

If one stream ran through a meadow, and the other ran through one of those forests, then the one through the forest would have lots more runoff sediment, which often isn't helpful for fish.
Just say global warming will make the fish and everything around them extinct unless we create an even bigger government that increases taxes and destroys wealth and freedom and prosperity and you should get an A. You might get extra credit if you make a claim like for every less human on the planet 10 species will not go extinct.
My AP Bio teacher wrote a lesson plan on the Impacts of Climate Change on Brook Trout in the Appalachians, and he gave it to us. I need help on one question:
Explain why some areas at the same elevation and of equal latitude might experience unequal fish mortality. Specifically, why might two creeks within one mile of each other have such variation in brook trout survivability given climate is equal?
