That extra heat is driving regional and seasonal temperature extremesreducing snow cover and sea iceintensifying heavy rainfall, and changing habitat ranges for plants and animals —expanding some and shrinking others.

The zero line represents the long-term Eart temperature for the whole planet; blue and red bars show the difference above or below average for each year. Temperatures were warmer than average across most global land and ocean areas during most of the year. The final frame of animation shows where annual temperatures were warmer red or colder blue than average. NOAA Climate. Record high sea surface temperatures were observed across parts of all oceans, including the North and South Atlantic Ocean, the western Indian Ocean, and areas of northern, central and southwestern Pacific Ocean.

No land or ocean areas were record cold for the year, and the only substantial pocket of cooler-than-average land temperatures was in central North America.

Though warming has not been uniform across the planet, the upward trend in the globally averaged temperature shows that more areas are warming than cooling. Changes in global average surface temperature from The Earth s Climate System Has Been Experiences warmest years on record have all occurred sinceand 9 of the 10 have occurred since The year is the only year from the twentieth century still among the ten warmest years on record. Bymodels project that global surface temperature will be more than 0. This similarity in temperatures regardless of total emissions is a short-term phenomenon: it reflects the tremendous inertia of Earth's vast oceans.

The high heat capacity of water means that ocean temperature doesn't react instantly to the increased heat being trapped by greenhouse gases.

The concept of an average temperature for the entire globe may seem odd. Temperatures vary from night to day and between seasonal extremes in the Northern and Southern Hemispheres. This means that some parts of Earth are quite cold while other parts are downright hot. To speak of the "average" temperature, then, may seem like nonsense.]
