Global temperature map by month

Air temperatures on Earth have been rising since the Industrial Revolution. 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.

Generate maps showing data for each of the climate divisions in the U. Climate Divisional Database. You can specify monthly or yearly values, ranks, or anomalies for temperature, precipitation, heating and cooling degree days, and drought indices. Where do these data come from? How do I use the site? What can I do with these data? Choose various ways to display the map by clicking buttons just above it.

Unlike the climate charts on this site, which are all original, these maps were adapted from others found on the web. The temperature and rainfall maps are somewhat modified output from climate mapping software available from the UN FAO Sustainable Development Department. See the Index Map for a quick interface to the 's of climate charts on this site. The original scale units are degrees Centigrade, the conversion to Fahrenheit is approximate. Predicted temperature increase from the baseline period of to From the Hadley Centre. Also see About the Global Warming Data on this site for a discussion of how this map is used in our location pages. The original scale units are meters per second, the conversion to miles per hour is approximate. This is average wind, with direction shown by arrows and speed shown by background color. The first is for January, the second is for July.

High CSI values mean climate change made the temperatures more likely. For levels at 2 or above, the Index is a multiple of how frequently a particular temperature will occur due to climate change. For example, a CSI of level 5 means that a temperature is occurring 5 times more frequently. This would be very difficult to encounter in a world without climate change—not necessarily impossible, just highly unlikely. For the positive conditions which occur much more often than the negative , we assigned a simple descriptor to these events:. Climate Shift Index levels are evaluated each day using temperatures from a state-of-the-art numerical weather model. Places and seasons with relatively small temperature variability combined with relatively strong temperature trends e.

Global temperature map by month

Air temperatures on Earth have been rising since the Industrial Revolution. 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. The majority of the warming has occurred since , at a rate of roughly 0.

After all, temperatures fluctuate by many degrees every day where we live. Where do these data come from? Climate Shift Index Change in likelihood due to climate change -5 0 5. According to the latest Synthesis Report pdf from the Intergovernmental Panel on Climate Change, there is no debate about the cause of this warming trend:. Leitzell, E. Because that is more carbon than natural processes can remove, atmospheric carbon dioxide amounts increase each year. Over land, values of surface air temperature from ERA-Interim are in effect determined quite directly from observational records for regions where plentiful observations of surface air temperature were made. Global surface temperature change. Climate Divisions - Monitoring References. Climate at a Glance. What can I do with these data? The past nine years have been the warmest years since modern recordkeeping began in Warmer-than-average areas are shades of red, and cooler-than-average areas are shades of blue.

In the atmosphere, millibar height pressure anomalies correlate well with temperatures at the Earth's surface. The average position of the upper-level ridges of high pressure and troughs of low pressure—depicted by positive and negative millibar height anomalies on the August and June-August maps, is generally reflected by areas of positive and negative temperature anomalies at the surface, respectively.

Climate Divisions - History History of the U. But the global temperature mainly depends on how much energy the planet receives from the Sun and how much it radiates back into space. National Climatic Data Center. Trends in annual surface temperature in the past few decades , top compared to the trend since the start of the 20th century , bottom. After all, temperatures fluctuate by many degrees every day where we live. The darker tha color, the bigger the difference from average. A one-degree global change is significant because it takes a vast amount of heat to warm all of the oceans, the atmosphere, and the land masses by that much. Generally, warming is greater over land than over the oceans because water is slower to absorb and release heat thermal inertia. As the maps show, global warming does not mean temperatures rise everywhere at every time by same rate. Romero eds. Places and seasons with relatively small temperature variability combined with relatively strong temperature trends e. Zhai, A.
