March was the 11th straight month a monthly worldwide temperature record was broken, the longest such streak since record-keeping began in 1880, the US National Oceanic and Atmospheric Administration (NOAA) has said.
"At the risk of sounding like a broken record, March set another heat record for the globe," Xinhua quoted the NOAA as saying in a statement on Tuesday.
"As Earth continues to warm and is influenced by phenomena such as El Nino, global temperature records are piling up."
For March, the average temperature across land and ocean surfaces was 1.22 degrees Celsius above the 20th century average of 12.7 degrees Celsius, according to the NOAA monthly report.
This was not only the highest for month of March in the 1880-2016 record, but also highest monthly temperature departure among all months on record, exceeding the previous all-time record set last month by 0.01 degrees Celsius.
Most of the Earth's land surfaces were warmer or much warmer than average in March, said report, with record warmth notable across eastern Brazil, most of eastern and central Africa, much of southeastern Asia, and large portions of northern and eastern Australia.
The weather phenomenon called El Nino continued to weaken in the central and eastern Pacific Ocean during March, but the month globally averaged sea surface temperature remained 0.81 degrees Celsius above the 20th century monthly average, also a record high.
