Blenheim monthly temperature trends show classic urban heat island (UHI) signal

Warming trends showing up strongest in the cooler months. Data is from a Govt fruit research institute the Marlborough Research Centre on the town outskirts. Charts by the MRC. Blenheim population growth. Small town temperature data – often classed as “rural” in global databases – can usually be shown to be riddled with UHI warming.

Huge temperature data shambles at Hokitika Aerodrome

Instrument change a ~decade ago –

amazing nobody at GHCN has noticed this complete failure to calibrate the new instrument with what it replaced – data from KNMI Climate Explorer. Minimum affected too. This has historic significance because Hokitika was one of the “rural” series in Jones original global dataset in the 1980’s that had a ~century of data. Ruined for good now. I think the NZ Metservice runs the stations.

For what it is worth there has been a divergence last month with SA, VIC and Tas reducing in price. NSW reducing a little and Qld now more expensive than NSW.

Progress Bali Mount Agung volcanic activity

When the news broke a while back I started following the ESDM site then there were the many evacuations – then the beast went quieter and I think the Govt said some could return to their homes. Prediction is very difficult. Anyway I thought I would share these links to graphics of seismic activity that look to be updated. I got my links from here

A serious eruption such as in 1964 has potential to cool global climate for a while.
