Global temperature map by month

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

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.

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 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.

Today, our activities—burning fossil fuels and to a lesser extent clearing forests—add about 11 billion metric tons of carbon equivalent to a little over 40 billion metric tons of carbon dioxide to the atmosphere each year.

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.

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. 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.

It may suggest the causes of differences and the datasets in which more confidence can be placed. Over this period, it is likely that well-mixed greenhouse gases GHGs contributed a warming of 1. For levels at 2 or above, the Index is a multiple of how frequently a particular temperature will occur due to climate change. Recent warming is much faster than the longer-term average, with some locations warming by 1 degree Fahrenheit or more per decade. World Climate Maps Unlike the climate charts on this site, which are all original, these maps were adapted from others found on the web. Wind Speed. Choose polygon type Contour. EO Explorer. Climate Divisions - Monitoring References. Record annual anomalies in average European temperatures of around 1. According to the U. Generate maps showing data for each of the climate divisions in the U. Map demonstrations. Uncertainties arise from regions where there are few direct temperature measurements, especially over the Arctic and Antarctic where variability from year to year is high. Chen, L.

Colors show where average monthly temperature was above or below its average. Blue areas experienced cooler-than-usual temperatures while areas shown in red were warmer than usual. The darker the color, the larger the difference from the long-term average temperature.

These are not absolute temperatures, but changes from the norm for each area. Because that is more carbon than natural processes can remove, atmospheric carbon dioxide amounts increase each year. The same is found for the JRA reanalysis. The increase in average temperature from to ranges from close to 0. The temperature and rainfall maps are somewhat modified output from climate mapping software available from the UN FAO Sustainable Development Department. Climate at a Glance. Zhai, A. Annual Global Climate Report. 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. The energy coming from the Sun fluctuates very little by year, while the amount of energy radiated by Earth is closely tied to the chemical composition of the atmosphere—particularly the amount of heat-trapping greenhouse gases. Pre-release values for February were also affected slightly by this error. Unlike the climate charts on this site, which are all original, these maps were adapted from others found on the web.
