Over the next few decades the earth stops spinning, so your day is as long as your year. This means that humanity can only now exist as nomads in the twilight zones, caught between the freezing cold of the dark side and the bombardment of radiation on the light side. The centripetal force that keeps the oceans in position is gone, so Earth becomes one super-continent with seas at the poles and impassably rugged terrain between. Civilisation as we know it is dead.
I only wish, to catch a fish, so juicy sweeeeeet...
