Global temperature map by month

High CSI values mean climate change made the temperatures more likely.

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.

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 The image below shows global temperature anomalies in , which tied for the fifth warmest year on record. The past nine years have been the warmest years since modern recordkeeping began in As the maps show, global warming does not mean temperatures rise everywhere at every time by same rate. Temperatures might rise 5 degrees in one region and drop 2 degrees in another. For instance, exceptionally cold winters in one place might be balanced by extremely warm winters in another part of the world. Generally, warming is greater over land than over the oceans because water is slower to absorb and release heat thermal inertia. Warming may also differ substantially within specific land masses and ocean basins.

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.

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. Brown, downward arrows show where local sea level is falling. This interactive map shows the latest day for which snow greater than 0. Heat maps and matching satellite images presented with a slider, so that readers can get a sense of how and why each city experiences such a wide range of temperatures on a hot summer day.

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. Forecast Generated On 24 Feb Currently unavailable Statistical uncertainties are too large in this region to calculate reliable CSI levels at this time. Data Format s. The ERA-Interim anomaly of 0. We value your feedback Help us improve our content Your Email Address. Matthews, T. High CSI values mean climate change made the temperatures more likely. They also arise from the adjustments needed to estimate sea surface temperature from measurements made at different depths and with different biases. These recent record values exceed pre record values by much more than the estimated uncertainties in the data values. The differences in temperature between the warmest and second-warmest months are also small 0. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable, cyclical events night and day, summer and winter and hard-to-predict wind and precipitation patterns. The atmospheric observing system underwent several improvements leading up to The paper also estimates that the atmosphere from was on average between 0. Places and seasons with relatively small temperature variability combined with relatively strong temperature trends e.

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.

Multiple independent research groups across the world perform their own analysis of the surface temperature data, and they all show a similar upward trend. In: Climate Change Synthesis Report. Choose polygon type Contour. Search Location. Comparing global temperature datasets helps to identify where and when they provide reliable information. Climate Divisions - Monitoring References. Currently unavailable Statistical uncertainties are too large in this region to calculate reliable CSI levels at this time. Return to top of page. Global surface temperature change. Goldfarb, M. The past nine years have been the warmest years since modern recordkeeping began in 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.
