Global temperature map by month

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, global temperature map by month. This would be very difficult to encounter in a world without climate change—not necessarily impossible, just highly unlikely.

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?

Yearly surface temperature compared to the 20th-century average from — Blue bars indicate cooler-than-average years; red bars show warmer-than-average years. NOAA Climate. The roughly 2-degree Fahrenheit 1 degrees Celsius increase in global average surface temperature that has occurred since the pre-industrial era in NOAA's record might seem small, but it means a significant increase in accumulated heat. 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. 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. In addition, it's clear that the rate of warming over the past few decades is much faster than the average rate since the start of the 20th century. Trends in annual surface temperature in the past few decades , top compared to the trend since the start of the 20th century , bottom. Recent warming is much faster than the longer-term average, with some locations warming by 1 degree Fahrenheit or more per decade. Differences are most dramatic in the Arctic, where the loss of reflective ice and snow amplifies the rate of warming. 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.

Warming may also differ substantially within specific land masses and ocean basins. Click to see more detail. Climate Divisions - History.

The maps and graphs in this section are based on pre-release data from ECMWF's ERA-Interim reanalysis and therefore are subject to change should a significant production problem be found to have occurred. The release of the maps and charts usually happens a few days after the last observations of each month have been made but the underlying data products are not made publicly available until they have been checked. In addition, the pre-release ERA-Interim data used in the monthly summaries for March and April were reduced by 0. Pre-release values for February were also affected slightly by this error. Final ERA-Interim data for public release have subsequently been produced by rerunning the period in question using corrected SST data. The final values for February and March are used in the monthly summaries from May onwards. Temperature anomalies larger than this can occur locally, especially at high latitudes in winter associated with anomalous sea-ice extent.

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. Temperature anomalies and percentiles are shown on the gridded maps below. Temperature anomalies for land and ocean are analyzed separately and then merged to form the global analysis. The percentile map on the right provides additional information by placing the temperature anomaly observed for a specific place and time period into historical perspective, showing how the most current month, season or year compares with the past. The August global surface temperature was 0. This was the sixth warmest August on record.

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. The maps above show temperature anomalies in five-year increments since Click on the arrow to run the animation. These are not absolute temperatures, but changes from the norm for each area. The data reflect how much warmer or cooler each region was compared to a base period of

In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. This would be very difficult to encounter in a world without climate change—not necessarily impossible, just highly unlikely. Record annual anomalies in average European temperatures of around 1. The leveling off of temperatures in the middle of the 20th century can be explained by natural variability and by the cooling effects of aerosols generated by factories, power plants, and motor vehicles in the years of rapid economic growth after World War II. Data Format s. Return to top of page. In addition, the pre-release ERA-Interim data used in the monthly summaries for March and April were reduced by 0. This is average wind, with direction shown by arrows and speed shown by background color. Land-based station. Climate Science Special Report , if yearly emissions continue to increase rapidly, as they have since , models project that by the end of this century, global temperature will be at least 5 degrees Fahrenheit warmer than the average, and possibly as much as Choosing instead the first fifty years for which HadCRUT4 provides values, , as the "pre-industrial" reference period gives a median estimate for that is 1. 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. The temperature and rainfall maps are somewhat modified output from climate mapping software available from the UN FAO Sustainable Development Department. This is based on our examination of the pre- and post values provided by the well-established conventional datasets, supplemented by the estimate by others that the temperature for the period was if anything colder than that for the latter half of the 19th century.

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. Using the coldest of the estimates for , that of HadCRUT4, the median rise above the level is 1. 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 length of data record becomes a limitation for ERA-Interim when it comes to ranking European temperatures for specific months of the year. This means that some parts of Earth are quite cold while other parts are downright hot. The darker tha color, the bigger the difference from average. Each value is then used to calculate a global temperature average.

In: Climate Change Synthesis Report. Berger, N. All show rapid warming in the past few decades, and all show the last decade as the warmest.
