NIWA takes shot at golf course ratings

Dr Turner determined that using NIWA’s in-house, high resolution weather model, known as the NZCSM – New Zealand Convective Scale Model – could result in a fairer comparison across all golf courses.NZCSM mean wind speeds from the past four years were applied to the ratings calculation of almost 400 golf courses across the country.

Sea temperatures around the coast have also been warmer than average, modifying colder air masses tracking towards New Zealand.Mr Noll said with the June and July temperatures tracking so far above average, this winter had a firm lead on last year’s figures.

June blows hot and cold – and possibly hottest of all

Scientists reveal how landmark ban gave planet fighting chance

Scientists reveal how landmark ban gave planet fighting chance

The new evidence reveals the planet’s critical ability to absorb carbon from the atmosphere could have been massively degraded sending global temperatures soaring if we still used ozone-destroying chemicals such as CFCs. New modelling by the international team of scientists from New Zealand, UK and the US, published today in top science journal Nature, paints a dramatic vision of a scorched planet Earth without the Montreal Protocol, what they call the “World Avoided”.
