It’s been a long time since my last post: apologies for that. You may blame a bad cold, an urgent need for root canal work, the peak of the truffle season (and truffle tours for culinary heroes1 ), the start of pruning and political distractions for the drop off in activity here. Normal service should […] … Read More

This morning’s NASA Earth Observatory image of the day shows the impact of last week’s heavy rain in Christchurch and Banks Peninsula on the sea around. The light blue colours show sediment washed off the land. If you visit the EO page, they provide a helpful reference image: the region snapped from space in late […] … Read More

The first major study to look at the impact of sea level rise on Christchurch and Banks Peninsula following the 2010/11 earthquake sequence projects a watery future for many parts of the city and its surrounding shorelines. The image above1 shows changes in ground elevation between 2003 and 2011 in the Christchurch region. Areas in […] … Read More

Two major new government reports on New Zealand’s emissions projections and the expected impacts of four degrees of warming on NZ agriculture were released without fanfare last Friday — the timing clearly designed to minimise media fallout from reports that highlight the paucity and ineffectiveness of current climate policy settings.
