Significant changes in the Google Search Algorithm
After much speculation, it is now official.  To address the massive growth in mobile traffic, Google is again augmenting its algorithm, this time, to favor mobile friendly sites over non mobile friendly sites in ranking search results.
Google is sending a pretty strong message.  The transparency of the rationale, coupled with the fact they are giving webmasters weeks to proactively address this change, indicates this is a big deal to Google.  Webmasters that have not invested in responsive design could find their ranking impacted negatively.
The following is taken directly from Google's Webmaster Central Blog.
"Starting April 21, we (Google) will be expanding our use of mobile-friendliness as a ranking signal. This change will affect mobile searches in all languages worldwide and will have a significant impact in our search results. Consequently, users will find it easier to get relevant, high quality search results that are optimized for their devices."
Why is Google doing this?  By steering traffic to responsive websites, users will have a better experience.  In 2014, depending on which study one looks at, between 50% and 60% of all online traffic came from mobile.  It is likely your website experiences a similar split in traffic.
There has never been a more important time to ensure your website is mobile friendly.
The implications on traffic to your website moving forward are clear.  If your website isn't responsive, much of the SEO work you may have invested in could disappear.  Another implication is that your competition that MAY have responsive websites MAY find they're way ahead of you in search results.  Don’t let that happen.
