It was the second warmest March - after March 2016 - in a database which goes as far back as 1880.

It was confirmed this week by NOAA’s National Center for Environmental Information (NCEI) that March 2017 was the second warmest March, globally, on record. The only warmer March in a database stretching over more than 1,620 months, was March 2016. The second place ranking was also confirmed by NASA.

In addition, March was the fourth warmest month – any month – in that database, coming behind February, March and January of 2016 and just ahead of February 2017.

Once again, the degree of warming is quite alarming. March was a massive 1.12 degrees Celsius above the long-term average. With January and February of 2017 amongst the warmest months ever recorded, there is an outside chance that 2017 could challenge 2016 as the warmest year on record.

This remains unlikely at this stage as we only came out of an El Nino, which tends to enhance global warming, earlier in 2016.

Nevertheless, a localised warming of surface waters in the eastern Pacific, which has resulted in heavy rain, flooding and landslides in Colombia, Ecuador and Peru, has been ongoing for several months.

It is certainly possible that another El Nino could develop later this year, despite such events usually occurring only every two to seven years. Such a development would certainly raise the possibility of 2017 challenging 2016 as the warmest year on record.

The record temperatures of March applied equally to land and sea. As a result, sea ice extent in both the Arctic and Antarctic was at record low levels.
