This year, warmest spring on record in NZ,..... warmest summer for seven years, UK,.... global temperatures risen by over one degree so far this last 100 years.

Both Arctic and Antarctic sea ice cover have extended this year, due in the north to a low pressure system in the atmosphere in that region.

Pacific sea temperatures have dropped also, this year, though ground temperatures in NZ are higher than last year, by aprox one degree.

El Nino/La Nina effect is regarded as having a part to play in this anomaly, and solar activity has just passed its cyclic peak, so less energy from the sun, so aiding the cooling process seen this last few months.

Global warming/climate change, caused by both natural and anthropogenic factors.
