comment Bad numerical approximations
When typing reals backticks indicate precision. To be honest, I find them mostly useless.

comment Bad numerical approximations
There's a backtick there that shouldn't be. My guess is that you copy-pasted Sqrt[2] over the real, but the real has a trace backtick which you didn't see, or mind. Remove that backtick.

comment How can Mathematica solve 7 equations and want to find 7 variables
There are too many errors in your input. If you are new to Mathematica, start with a simpler problem.

comment A Case of DeleteCases for WeatherData
The new maps in Mathematica 10 look really cool. I think at least one of us botched something, because we get quite stark disagreement on wind direction. I'll check tomorrow where the wind actually blows. ;)

comment Finding Roots of Non-linear Systems: Rescaling polynomials
It's impossible to answer your question as it stands, however I could hint at the Method->... and WorkingPrecision->... options, that might get you sorted.

comment Mathematica 10 Notebook Fonts Look Bad
Thanks for all the investigative work! I just wish we could have found some kind of workaround, apart going to therapy of course.
