NZ’s Warmest Decade – It’s Official

9th January 2010

The National Institute of Water & Atmospheric Research (NIWA) has confirmed that the decade of the 2000’s was the warmest on record for New Zealand.   NIWA says the decade (2000–2009)waS slightly warmer for New Zealand than the decade of the 1980s, which was the previous warmest decade.   “This result is caused by a combination of natural variability and a background warming trend,” says Dr James Renwick, NIWA Principal Scientist.   The New Zealand ‘ranking’ of warm decades is:

• Warmest: — 2000’s

• 2nd place: — 1980’s

• 3rd place:  — 1970’s

• 4th place:   — 1990’s

NIWA’s finding is consistent with a World Meteorological Organization (WMO) statement that the decade from 2000–2009 is likely to be the warmest decade on record for global average temperatures.   The WMO predicts ed that for the globe as a whole 2009 will rank in the top ten warmest years on record.   For New Zealand, however, the year 2009 itself was slightly colder than the 1971–2000 average.   The full details will be issued next Wednesday, January 13.   NIWA will then release its official Annual Climate Summary for 2009.
