First half of 2016 hottest in New Zealand's history

First half of 2016 hottest in New Zealand's historyThe first six months of 2016 proved to be the hottest start to a year that scientists have ever recorded in New Zealand.

Temperatures in the South Pacific nation were 1.4 degrees Celsius (2.5 Fahrenheit) above the long-term average for the first half of the year, according to the government-funded National Institute of Water and Atmospheric Research.

That's the highest since record-keeping began more than a century ago, and significantly higher than the previous record of 1.1 Celsius above average, reached in 1938 and again in 1999.

Chris Brandolino, a scientist at the research agency, said Monday that ocean temperatures in the Tasman Sea to the west of New Zealand have been unusually warm this year and that warmer winds from the north have also predominated.

"What's happened in the background is that the Earth has continued to warm as greenhouse gas levels have risen," he said.

The agency reported that carbon dioxide levels recorded at a station near Wellington passed 400 parts per million in June for the first time. The threshold is seen as significant internationally as an indicator of climate change.

Transpower, the government agency which owns the national electricity grid, provided figures to The Associated Press showing that New Zealanders consumed about 2 percent less electricity in June than they did during the same month a year earlier, likely due in part to lower heating requirements.

The Transpower figures showed a June drop of 8 percent in Wellington and 7 percent in Christchurch compared with a year earlier. Those cities are typically cooler in winter than the largest city, Auckland, where the drop was 2 percent.

The June month was the third-hottest June ever recorded in New Zealand and the hottest ever recorded in Christchurch, according to the research agency.
