tough to overstate how quickly science funding in New Zealand has been blown to pieces - on Friday the NZ govt straight up disbanded the Marsden fund (our version of the NSF) it'll be replaced by a 'transition fund' with less money and zero information, as of yet, about what it will support

Do you have shifting baseline syndrome? Yesterday's global sea-surface temperature was 5.17 standard deviations above the 1982-2011 average (first 30 years of data). The odds of this happening by chance are about 8,500,000-to-1 against (without climate change).
