ENSO events are characterised by fluctuations in temperature between the ocean and atmosphere in the tropical Pacific, which help to make some years warmer and some cooler. Chart by Carbon Brief using Highcharts.Įl Niño and La Niña events – collectively referred to as the El Niño Southern Oscillation, or ENSO – are the main driver of year-to-year variation on top of the long-term surface warming trend. Anomalies plotted with respect to a 1981-2010 baseline. The values in this chart will be updated when that data becomes available.Īnnual global mean surface temperatures from NASA GISTEMP, NOAA GlobalTemp, Hadley/UEA HadCRUT5, Berkeley Earth, and Copernicus/ECMWF (lines), along with 2022 temperatures to-date (January-March, coloured dots). Year-to-date values are not yet available from Hadley/UEA due to reporting delays for March. Surface temperature records have shown around 0.9C warming since the year 1970, a warming rate of about 0.19C per decade. Values are shown relative to a common baseline period – the 1981-2010 average temperature for each series. The coloured lines show the temperature for each year, while the dots on the right-hand side show the year-to-date estimate for January to March 2022. The chart below compares the annual global surface temperatures from these different groups since 1970 – or 1979 in the case of Copernicus/ECMWF. February was a bit cooler, coming in at somewhere between the sixth and ninth warmest on record. January and March were the sixth and fifth warmest, respectively, across all the datasets. Note that Hadley and Berkeley go back to 1850, NASA and NOAA go back to 1880, and Copernicus/ECMWF is only available since 1979. Rankings of 2022 temperatures by month across different datasets. The table below shows the ranking of months in 2022 compared to the same month in all prior years since records began. Year-to-date temperature anomalies for each month from 2014 to 2022 from NASA GISTEMP. It shows the temperature of the year-to-date for each month of the year, from January through to the full annual average. The figure below shows how temperatures to-date compare to prior years in the NASA dataset. The temperatures in the first three months of 2022 were the seventh warmest first quarter of the year on record, behind all of the past six years – but warmer than every year on record prior to 2015. Copernicus/ECMWF also produces a surface temperature estimate based on a combination of measurements and a weather model – an approach known as “ reanalysis”. Global surface temperatures are recorded and reported by a number of different international groups, including NASA, NOAA, Met Office Hadley Centre/UEA and Berkeley Earth. In Antarctica, a March heatwave saw temperatures nearly 40C above normal in the eastern part of the continent.Īrctic sea ice currently is on the low end of its historical range, while Antarctic sea ice saw the lowest sea ice extent on record in late February. March 2022 saw record warmth over China and large parts of southern Asia, as well as exceptionally high temperatures in the Arctic. The first four months of 2022 were the fifth warmest start to a year on record so far. Not every year is expected to set a new record for the surface – and 2022 annual temperatures will likely end up well in-line with the long-term warming trend that the world has experienced over the past five decades. It is very unlikely to be a record warm year due to moderately strong La Niña conditions in the early part of the year that are projected to continue for at least the next six months. Some components list multiple scores, disk for read and write performance for instance, and the processor the three values float, integer and hash ops if you click on the show details link.After a slightly cooler 2021 on the Earth’s surface, the world is on track for 2022 to be somewhere between the fourth and eighth warmest year since records began in the mid-1850s. Scores are straightforward for the most part. Only the operating system of the PC, the processor, and the video card are listed by the application. Novabench displays scores for all tested hardware components, as well as general information about the tested system. The benchmark run time is short it takes about a minute to run all tests, and even less if you just run one of the tests. You get options to run all tests at once, or only specific tests by selecting them from the tests menu at the top. The free version of Novabench is not offered as a portable version, the Pro version is. The program is offered as a 80 Megabyte file that you need to install on the target system. Novabench is a free for non-commercial use benchmark for Windows that you can run to test the system's processor, RAM, disk and video card performance.
