2018 was second equal hottest year on record, ‘alarming trend’ – NIWA

NIWA (National Institute of Water and Atmospheric Research) say that 2018 was the second warmest year on record, and four of the past six years were in the top five warmest.

RNZ:  2018 climate continues ‘alarming trend’ – NIWA

Temperatures in 2018 continued to hit record highs, with scientists calling the year a continuation of an “alarming trend”.

January was a record high, but for the year it wasn’t a record.

The year as a whole was the second-equal warmest on record, along with 1998.

The average temperature was 13.41C, not quite reaching the high set in 2016 with an average of 13.45C.

NIWA principal scientist Chris Brandolino said four of the past six years were now in the top five of warmest ever recorded, which was extremely concerning.

“[The year of] 2016 was the warmest, 2017 was the 5th warmest. This year equal-second warmest and I think 2015 was the third warmest,” Mr Brandolino said.

“So four out of the past six years we’ve finished top five and unfortunately part of a long-term and alarming trend.”

Mr Brandolino said there were 49 locations which reached record or near record temperatures around the country.

Mr Brandolino said the warm weather was due to three main components – sea surface temperatures, air flow from tropic and sub-tropic areas and an increase in greenhouse gasses.

“The increases in greenhouses that we continue to see is warming in the background,” he said.

“In other words, we are seeing a long-term tailwind of temperatures. Our changing climate is acting as a long-term tailwind for high temperatures.”

@NIWAWeather:

January 2018 was New Zealand’s warmest month on record, recording a remarkable 3.1˚C above average.

The rest of 2018:

  •   6 months saw above average temps.
  •   6 months saw near average temps.
  •   0 months saw below average temps.

♨️ 49 locations observed record or near-record high mean temperatures.

❄️ 0 locations observed record or near-record low mean temperatures.

For minimum temperatures, 2018 was the warmest on record at +0.94˚C above average in New Zealand. Research has shown that historical warming rates have been larger for overnight minimum temperatures compared with daytime maximum temperatures.

This is a bit misleading stating ‘warmest year on record’:
