Extreme weather: Get ready to see more of it, scientists say.

A map of significant climate events for the United States in June looks almost apocalyptic: hellish heat, ferocious fires and severe storms leaving people injured, homeless and even dead.

That followed a warm winter and early season droughts. News came Monday that the mainland United States experienced its warmest 12 months since the dawn of record-keeping in 1895.

And on Tuesday, the National Oceanic and Atmospheric Administration (NOAA) released a report calling 2011 a year of extreme weather.
