Since this is basically an editorial, it's not appropriate as a news item. But I thought it was a good read, from an insiders perspective on how research and results based science has slowly had to defend centuries old practices from groups that have a financial interest in maintaining the status quo.

A recent headline—"Failed doubters trust leaves taxpayers six-figure loss"—marked the end of a four-year epic saga of secretly funded climate denial, the harassment of scientists, and a tying-up of valuable government resources in New Zealand.
It’s likely to be a familiar story to my scientist colleagues in Australia, the UK, the US, and elsewhere around the world.
But if you’re not a scientist and are genuinely trying to work out who to believe when it comes to climate change, then it’s a story you need to hear, too. Because while the New Zealand fight over climate data appears to finally be over, it’s part of a much larger, ongoing war against evidence-based science.
From number crunching to controversy
In 1981, as part of my PhD work, I produced a seven-station New Zealand temperature series known as 7SS to monitor historic temperature trends and variations from Auckland to as far south as Dunedin in southern New Zealand.
A decade later, while at the NZ Meteorological Service in 1991-92, I revised the 7SS using a new homogenization approach to make New Zealand’s temperature records more accurate, such as adjusting for when temperature gauges were moved to new sites. For example, in 1928, Wellington’s temperature gauge was relocated from an inner suburb near sea level up into the hills at Kelburn, where—due to its higher, cooler location—it recorded much cooler temperatures for the city than before.
With statistical analysis, we could work out how much Wellington’s temperature has really gone up or down since the city’s temperature records began back in 1862 and how much of that change was simply due to the gauge being moved uphill. (You can read more about re-examining NZ temperatures here.)
So far, so uncontroversial.
But in 2008, while I was working for a NZ government-owned research organization—the National Institute of Water and Atmospheric Research (NIWA)—we updated the 7SS. And we found that at those seven stations across the country, from Auckland down to Dunedin, there was a warming trend of 0.91ºC (1.63ºF) between 1909 and 2008.
Soon after that, things started to get heated.
