How to fix Render-Blocking Java Script in WordPress?

Hi, PageSpeed Insights is telling me to Eliminate render-blocking JavaScript in above-the-fold content:

https://beardstrokings.com/…s/jquery/jquery-migrate.min.js?ver=1.4.1

And Optimize CSS Delivery of the following:

https://fonts.googleapis.com/css?family=Oxygen:400,300,700

How would I go about doing that?

Cheers!
