Greenhouse and trace gases

Latest news

NIWA scientists leading Aotearoa New Zealand’s MethaneSAT agricultural emissions science programme are gearing up for the launch of its satellite in coming weeks.
New Zealand researchers have contributed to the first ever stocktake of global greenhouse gas emissions.
A research project co-led by Blue Carbon Services and NIWA will aim to provide New Zealand’s first national estimate of natural kelp-carbon sequestration in the marine environment.
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 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.

Lauder celebrates 50 years of atmospheric research.

The return of the upgraded RV Tangaroa represents a huge advancement for New Zealand science and exploration

NIWA today welcomed home RV Tangaroa, New Zealand’s only deepwater research vessel, after a $20 million dollar upgrade to enhance its ocean science and survey capabilities.

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

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 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.

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.
