Guest Work Jun 03, 2017

Michael Reddell May 24, 2017

I’ve never had that much interest in climate change.  Perhaps it comes from living in Wellington.   If average local temperatures were a couple of degrees warmer here most people would be quite happy.    And as successive earthquakes seem to have the South Island pushing under the North Island, raising the land levels around here –  you can … Read More
