NOAA map, based on data from NOAA Centers for Environmental Information. Only a few locations, most of them in Southern Hemisphere oceans, cooled over this time period. Most of the planet is warming (yellow, orange, red). Trends in global average surface temperature between 19 in degrees Fahrenheit per decade.
As the map below shows, most land areas have warmed faster than most ocean areas, and the Arctic is warming faster than most other regions.
That extra heat is driving regional and seasonal temperature extremes, reducing snow cover and sea ice, intensifying heavy rainfall, and changing habitat ranges for plants and animals-expanding some and shrinking others. The roughly 2-degree Fahrenheit (1 degrees Celsius) increase in global average surface temperature that has occurred since the pre-industrial era (1880-1900) might seem small, but it means a significant increase in accumulated heat. Given the tremendous size and heat capacity of the global oceans, it takes a massive amount of heat energy to raise Earth’s average yearly surface temperature even a small amount.
