I (think I) read somewhere on the web the factoid that, if we could restrict the impacts of climate change to within the borders of the country responsible for the greenhouse gas emissions, the temperature of the USA would rise by (something like) 22° Celsius. Now I can't for the life of me find it again. Does anyone know where I read this, or am I simply imagining things? I'd like to be able to cite an authority for my assertion. Climate change skeptics need not apply.

Here's an obnoxious school question that's been nagging me for days:
Suppose that the height (at the shoulder) of adult African bull bush elephants is normally distributed with µ = 3.3 meters and ∂ = .2 meter. The elephant on display at the Smithsonian Institute has a height 4 meters and is the largest elephant on record. What is the probability that an adult African bull bush elephant has height 4 meters or more? [more inside]
