The image below shows global temperature anomalies in 2021, the sixth warmest year on record. (The global mean surface air temperature for that period was 14☌ (57☏), with an uncertainty of several tenths of a degree.) The data reflect how much warmer or cooler each region was compared to a base period of 1951-1980. (Click on the arrow to run the animation.) These are not absolute temperatures, but changes from the norm for each area. The maps above show temperature anomalies in five-year increments since 1880. The majority of the warming has occurred since 1975, at a rate of roughly 0.15 to 0.20☌ per decade. While natural variability plays some part, the preponderance of evidence indicates that human activities-particularly emissions of heat-trapping greenhouse gases-are mostly responsible for making our planet warmer.Īccording to an ongoing temperature analysis led by scientists at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by at least 1.1° Celsius (1.9° Fahrenheit) since 1880. So, in this example, there is a 40 percent probability for at least 0.Air temperatures on Earth have been rising since the Industrial Revolution. The 'Probability of Precipitation' (PoP) simply describes the probability that the forecast grid/point in question will receive at least 0.01' of rain. will it rain over 40 percent of the area?
