Global temperature map by month

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.

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?

Global temperature map by month

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. This means that some parts of Earth are quite cold while other parts are downright hot.

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. 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:.

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.

Find out about measuring, modeling, and predicting climate and ways to find and use climate data. Map of the historic probability of there being at least 1 inch of snow on the ground in the Lower 48 states on December 25 based on the latest U. When does the climate record say you can expect the season's first snow? Compare projected changes in downhill ski season length by if we follow a moderate versus a high pathway of carbon emissions. Interactive table and map showing state- and county-specific drought impacts ranked by U. Drought Monitor categories, including impacts to industry, natural resources, and human health. Blue, upward arrows show where local sea level is rising.

Global temperature map by month

As seen in the graph below, ENSO can have an effect on global temperatures. Although the monthly global temperatures were above average throughout the year, February was the coldest month of for the globe. However, after the month of February, temperatures were at 0. The year culminated as the sixth warmest year on record for the globe with a temperature that was 0.

In the animation at the top of the page and in the bar chart below, the years from to tend to be cooler, then level off by the s. Return to top of page Wind Speed This is annual average wind speed measured 50 meters above the ground or sea. Global surface temperature change. Fossil CO2 emissions at record high in 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: Climate Change Synthesis Report. The image below shows global temperature anomalies in , which tied for the fifth warmest year on record. Average Temps. Stewart, and T. 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. Return to top of page Global Warming Predicted temperature increase from the baseline period of to

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 September map, 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.

The following table shows corresponding annual averages from onwards, and the spread in these values. Global surface temperature change. Return to top of page Total Rainfall The original scale units are millimeters, the conversion to inches is approximate. In practice, most such statements about warm months and years are very likely to be valid for the whole of the industrial era, especially for global averages and annual European averages. For ERA-Interim, the range of record anomalies is from 0. Why should we care about one or two degrees of global warming? Final ERA-Interim data for public release have subsequently been produced by rerunning the period in question using corrected SST data. It may suggest the causes of differences and the datasets in which more confidence can be placed. Read more about how the global surface temperature record is built in our Climate Data Primer. Gomis, M. For instance, exceptionally cold winters in one place might be balanced by extremely warm winters in another part of the world. Values to see actual observed values averaged across the geography, parameter, and time indicated; Ranks to see how your period of interest compares to the historical record; Mean to see the 20th century average for the month or season indicated; or Anomalies to see how the indicated period compared to the 20th century average for the same month or season.
