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. 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, global temperature map by month, the pre-release ERA-Interim data used in the monthly summaries for March and April were reduced by 0.

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:.

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. 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.

Maycock eds. For ERA-Interim, the range of record anomalies is from 0.

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.

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. The years — all rank among the ten warmest years on record. The year was also the 45th consecutive year since with global temperatures, at least nominally, above the 20th century average. Of note, the year , which was the first year to set a new global temperature record in the 21st century, currently ties with as the 10th warmest year on record and ranks as the ninth warmest on record. Overall, the global annual temperature has increased at an average rate of 0. The Northern Hemisphere surface temperature was also the sixth highest on record.

Warmer-than-average areas are shades of red, and cooler-than-average areas are shades of blue. It may suggest the causes of differences and the datasets in which more confidence can be placed. To calculate a global average temperature, scientists begin with temperature measurements taken at locations around the globe. 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. For global-mean temperature, no month prior to in the HadCRUT4 dataset has an anomaly as large as 0. Differences in surface temperature datasets. Yu, and B. See the Index Map for a quick interface to the 's of climate charts on this site. References Hansen, J. Values over sea prior to are further adjusted by subtracting 0.

The seasonal cycle of temperature variation on the earth's surface. This version is labeled in English and Celsius.

The maps and graphs Access the maps and data. Climate Divisional Database. 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. In contrast, greenhouse gases accumulated slowly, but they remain in the atmosphere for a much longer time. 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 following table shows corresponding annual averages from onwards, and the spread in these values. Air temperature,. Pirani, S. See the Index Map for a quick interface to the 's of climate charts on this site. Differences in surface temperature datasets. These are not absolute temperatures, but changes from the norm for each area.
