Description 20200509 Emergence of temperatures from range of normal historical variability - tropical vs northern Americas (Hawkins).gif	English: Animated graphic of temperature changes in tropical America and in Northern America, atop 1 and 2 standard deviations of normal variability. Source of graphs: Hawkins, Ed From the familiar to the unknown . Climate Lab Book (professional blog) ( March 10, 2020 ). Archived from the original on April 23, 2020 . ( Direct link to image ; Hawkins credits Berkeley Earth for data.) "The emergence of observed temperature changes over both land and ocean is clearest in tropical regions, in contrast to the regions of largest change which are in the northern extra-tropics. As an illustration, northern America has warmed more than tropical America, but the changes in the tropics are more apparent and have more clearly emerged from the range of historical variability. The year-to-year variations in the higher latitudes have made it harder to distinguish the long-term changes."
