Dr Sara Mikaloff-Fletcher is looking to turn the internationally accepted science of monitoring greenhouse gas emissions upside down—and the rest of the world is watching closely.
 

Not warming to climate change

The latest climate change reports from the Intergovernmental Panel on Climate Change (IPCC) reinforce the urgent need to reduce global greenhouse gas emissions as well as to adapt to the impacts of climate change. Michelle Sutton finds that the news is mixed for New Zealand’s agricultural sector.

Scientists discover abrupt increase in CO2 uptake by the land biosphere

12 July 2012

Scientists have discovered an abrupt increase in the uptake of atmospheric carbon dioxide by the land biosphere since1988. Without this natural increase in uptake, the amount of carbon dioxide in the atmosphere would probably have increased even more rapidly over the last two decades.

NIWA stands by its statement on methane rise

23 December 2009

The statement made by NIWA Principal Scientist, Dr Keith Lassey in a TV3 news story about methane (22 Dec 2009) is correct.

NIWA says greenhouse gas methane is on the rise again

22 December 2009

The concentration of methane in the atmosphere is rising, according to measurements made by NIWA.

NIWA has today released measurements from its globally significant Baring Head station showing that southern hemisphere atmospheric methane increased by 0.7% over the two-year period 2007–08. While this increase may not sound like much, it is about 35 times more than all the methane produced by New Zealand livestock each year.

NIWA selects IBM to provide new supercomputer to advance environmental forecasting

28 August 2009

NIWA and IBM today announced a multi-million dollar partnership where NIWA will purchase one of the world’s most powerful supercomputers for use in environmental forecasting.

Bio-oil from wastewater algae

This project will demonstrate the commercial feasibility of producing bio-oil by the conversion of algae biomass that has been grown in wastewater treatment facilities. In particular we aim to maximise algae production in High Rate Algal Ponds (HRAP) by adding carbon dioxide, and demonstrate energy efficient conversion of algal biomass to bio-oil.
