Climate Change In New Zealand
Climate change in New Zealand involves historical, current and future changes in the climate of New Zealand; and New Zealand's contribution and response to global climate change. Summers are becoming longer and hotter, and some glaciers have melted completely and others have shrunk. In 2021, the Ministry for the Environment estimated that New Zealand's gross emissions were 0.17% of the world's total gross greenhouse gas emissions. However, on a per capita basis, New Zealand is a significant emitter, the sixth highest within the Annex I countries, whereas on absolute gross emissions New Zealand is ranked as the 24th highest emitter. Almost half New Zealand's greenhouse gas emissions are from Agriculture in New Zealand, agriculture, mainly methane from sheep and cow belches. Between 1990 and 2019, New Zealand's gross emissions (excluding removals from land use and forestry) increased by 26%. When the uptake of carbon dioxide by forests (sequestration) is taken into account, net ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrous Oxide
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or nos, is a chemical compound, an oxide of nitrogen with the formula . At room temperature, it is a colourless non-flammable gas, and has a slightly sweet scent and taste. At elevated temperatures, nitrous oxide is a powerful oxidiser similar to molecular oxygen. Nitrous oxide has significant medical uses, especially in surgery and dentistry, for its anaesthetic and pain-reducing effects. Its colloquial name, "laughing gas", coined by Humphry Davy, is due to the euphoric effects upon inhaling it, a property that has led to its recreational use as a dissociative anaesthetic. It is on the World Health Organization's List of Essential Medicines. It is also used as an oxidiser in rocket propellants, and in motor racing to increase the power output of engines. Nitrous oxide's atmospheric concentration reached 333 parts per billion (ppb) in 2020, increasing at a rat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauna Loa Observatory
The Mauna Loa Observatory (MLO) is an atmospheric baseline station on Mauna Loa, on the island of Hawaii, located in the U.S. state of Hawaii. The observatory Since 1958, initially under the direction of Charles Keeling, followed by his son Ralph and later Elmer Robinson, Mauna Loa Observatory (MLO) has been monitoring and collecting data relating to atmospheric change, and is known especially for the continuous monitoring of atmospheric carbon dioxide (CO2), which is sometimes referred to as the Keeling Curve. The observatory is under the Earth System Research Laboratory which is part of the National Oceanic and Atmospheric Administration (NOAA). According to the NOAA, Mauna Loa is the world's oldest continuous CO2 monitoring station, and the world's primary benchmark site for measurement of the gas. The latest observation of CO2 concentrations from MLO can be found at web sites along with data from other sites and trends at Mauna Loa. The MLO levels can be compared w ...

The New Zealand Herald
''The New Zealand Herald'' is a daily newspaper published in Auckland, New Zealand, owned by New Zealand Media and Entertainment, and considered a newspaper of record for New Zealand. It has the largest newspaper circulation of all newspapers in New Zealand, peaking at over 200,000 copies in 2006, although circulation of the daily ''Herald'' had declined to 100,073 copies on average by September 2019. Its main circulation area is the Auckland region. It is also delivered to much of the upper North Island including Northland, Waikato and King Country. History ''The New Zealand Herald'' was founded by William Chisholm Wilson, and first published on 13 November 1863. Wilson had been a partner with John Williamson in the ''New Zealander'', but left to start a rival daily newspaper as he saw a business opportunity with Auckland's rapidly growing population. He had also split with Williamson because Wilson supported the war against the Māori (which the ''Herald'' termed "t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baring Head
Baring Head ( mi, Ōrua-pouanui, officially gazetted as Baring Head / Ōrua-pouanui) is a headland, located between Wellington Harbour and Palliser Bay at the southern end of the North Island of New Zealand. It marks the southern end of Fitzroy Bay. The Baring Head Lighthouse, built in 1935, was the first light in New Zealand to start operating immediately on electricity. The Baring Head Atmospheric Research Station, administered by National Institute of Water and Atmospheric Research, provides the longest continuous record of atmospheric carbon dioxide in the Southern Hemisphere. The headland is administered by Wellington Regional Council as part of East Harbour Regional Park. Geography The reserve includes the lower reaches and mouth of Wainuiomata River and the coastal encampment around Baring Head. The rugged hills are visible from parts of Wellington City. Baring Head is one of the Wellington Region's “coastal habitats of significance for indigenous birds”. Ther ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria University Of Wellington
Victoria University of Wellington ( mi, Te Herenga Waka) is a university in Wellington, New Zealand. It was established in 1897 by Act of Parliament, and was a constituent college of the University of New Zealand. The university is well known for its programmes in law, the humanities, and some scientific disciplines, and offers a broad range of other courses. Entry to all courses at first year is open, and entry to second year in some programmes (e.g. law, criminology, creative writing, architecture, engineering) is restricted. Victoria had the highest average research grade in the New Zealand Government's Performance Based Research Fund exercise in both 2012 and 2018, having been ranked 4th in 2006 and 3rd in 2003.

Dave Lowe (atmospheric Scientist)
David Charles Lowe (born 1946) is a New Zealand atmospheric scientist who was instrumental in setting up the Baring Head atmospheric CO programme in 1972. A researcher and educator, he was one of the lead authors to a 2007 Intergovernmental Panel on Climate Change (IPCC) report which was recognised with a Nobel Peace Prize. Lowe has worked with others such as Charles David Keeling, to measure the amount of CO in the atmosphere and how this is contributing to climate change, in particular global warming. He is an Adjunct Professor of Atmospheric Chemistry at the Antarctic Research Centre, Victoria University of Wellington. Lowe's memoir was published in 2021 and received favourable reviews in the New Zealand media. Early life and education Lowe had a rural upbringing in Bell Block, Taranaki, New Zealand. He attended New Plymouth Boys High School but was "bullied and unhappy", so after three years and having gained School Certificate (New Zealand), left and worked in a telephon ...

Charles David Keeling
Charles David Keeling (April 20, 1928 – June 20, 2005) was an American scientist whose recording of carbon dioxide at the Mauna Loa Observatory confirmed Svante Arrhenius's proposition (1896) of the possibility of anthropogenic contribution to the greenhouse effect and global warming, by documenting the steadily rising carbon dioxide levels. The Keeling Curve measures the progressive buildup of carbon dioxide, a greenhouse gas, in the atmosphere. Early life and early career Keeling was born in Scranton, Pennsylvania, to Ralph Keeling and Grace L Keeling (née Sherberne). His father, an investment banker, excited interests of astronomy in a 5-year-old Charles, while his mother instilled a lifelong love of music. He graduated with a degree in chemistry from the University of Illinois in 1948. Charles Keeling earned a PhD in chemistry from Northwestern University in 1953 under Malcolm Dole, a polymer chemist. Most of Dole's graduates were going straight into the oil industry; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZ Greenhouse Gases By Sector
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs signed ...

Carbon Dioxide Equivalent
Global warming potential (GWP) is the heat absorbed by any greenhouse gas in the atmosphere, as a multiple of the heat that would be absorbed by the same mass of carbon dioxide (). GWP is 1 for . For other gases it depends on the gas and the time frame. Carbon dioxide equivalent (e or eq or -e) is calculated from GWP. For any gas, it is the mass of that would warm the earth as much as the mass of that gas. Thus it provides a common scale for measuring the climate effects of different gases. It is calculated as GWP times mass of the other gas. Methane has GWP (over 100 years) of 27.9 meaning that, for example, a leak of a tonne of methane is equivalent to emitting 27.9 tonnes of carbon dioxide. Similarly a tonne of nitrous oxide, from manure for example, is equivalent to 273 tonnes of carbon dioxide. Values Carbon dioxide is the reference. It has a GWP of 1 regardless of the time period used. emissions cause increases in atmospheric concentrations of that will last thousan ...
