The consensus of the people I know who have lived her for decades is that Southern California is getting hotter year by year.
Scorcher (n) - An extremely hot day. First appears in English in 1874. From the verb to scorch, meaning to burn on the surface. The origin is not certain. Some say it comes from the Old Norse word skorpna meaning to shrivel up. Others content the source word is the Latin word excorticare, meaning to flay.
