The Land-Ocean Temperature Index (LOTI) from the global map of February and March 2017 showed that the former month proved much warmer in Siberia and North America than the LOTI based on 1951 to 1980. However, Europe was comparatively warmer. On the other hand, the latter month showed that Russia and Europe were also warm as compared to the period from 1951 to 1980. Where most areas of the US were warm, Alaska remained cool.
Scientists at the Goddard Institute for Space Studies (GISS), which is based in New York and a part of NASA, did monthly analysis for 2017 February and March global temperatures and found out that these months, were the second-warmest from the last 137 years.
This February, a 1.1 degree Celsius temperature was recorded, which was warmer than the years from 1951 to 1980. During the last two years, two temperature anomalies were recorded in February.
This March, a 1.12 degree Celsius temperature was recorded, which was warmer than the years from 1951 to 1980. Two temperature anomalies were recorded in March for the past two years.
Both months were recorded as the hottest in 2016, with a 1.3 degrees Celsius for February and 1.27 degrees Celsius for March. Since the past two years, this temperature has been warmer as compared to both months’ mean temperature. This year, in February, the temperature was cooler by 0.20 degrees Celsius and in March; the temperature was cooler by 0.15 degrees Celsius. Where this year’s February was cooler than last year, March was warmer by 0.2 degrees Celsius than last year.
Data collected by the GISS team for the monthly analysis, which is assembled from various sources. This includes data that is publically available and is acquired from around the world through 6,300 meteorological stations, Atlantic research stations and buoy and ship based instruments that measure the temperature of the sea surface. Each month’s data is recorded and is compared with previous models to predict upcoming temperatures through changes in the past and recent temperatures.
In order to make sure that the observations made are accurate and closer to their predictions, the global temperature records are reviewed starting from 1880. Any temperatures recorded before these years are not eligible, since they did not cover the entire planet. Every month, the analyses are updated, that is if additional information comes through. Due to this, one cannot be ever sure how the temperature will take a turn and therefore, the result keeps changing.
