Rising nitrous oxide (N2O) emissions are jeopardizing the climate goals of the Paris Agreement, according to a major new study by an international team of scientists. The growing use of nitrogen fertilizers in the production of food worldwide is increasing atmospheric concentrations of N2O — a greenhouse gas 300 times more potent than carbon dioxide (CO2) that remains in the atmosphere for more than 100 years.
Published in the journal?Nature, the study was led Auburn University, in the US, and involved scientists from 48 research institutions in 14 countries — including the University of East Anglia (UEA) in the UK — under the umbrella of the Global Carbon Project and the International Nitrogen Initiative.
The aim was to produce the most comprehensive assessment to date of all global sources and sinks of N2O. Their findings show N2O emissions are increasing faster than any emission scenario developed by the Intergovernmental Panel on Climate Change (IPCC), consistent with greenhouse gas scenarios that lead to global mean temperature increases well above 3?C from pre-industrial levels.
The study points to an alarming trend affecting climate change: N2O has risen 20 per cent from pre-industrial levels — from 270 parts per billion (ppb) in 1750 to 331ppb in 2018 — with the fastest growth observed in the last 50 years due to emissions from human activities.
Prof Hanqin Tian, director of the International Center for Climate and Global Change Research at Auburn University’s School of Forestry and Wildlife Sciences, co-led the study. “The dominant driver of the increase in atmospheric nitrous oxide comes from agriculture, and the growing demand for food and feed for animals will further increase global nitrous oxide emissions,” said Prof Tian. “There is a conflict between the way we are feeding people and stabilizing the climate.”
Like CO2, N2O is a long-lived greenhouse gas and is also currently the most significant human-induced agent depleting the stratospheric ozone layer, which protects Earth from most of the Sun’s harmful ultraviolet radiation. Human-induced emissions, which are dominated by nitrogen additions to croplands, increased by 30 per cent over the past four decades to 7.3 teragrams of nitrogen per year.
The analysis also reveals an emerging N2O-climate ‘feedback’ resulting from interactions between nitrogen additions to crops for food production and global warming, further enhancing emissions derived from agriculture.
The study found that the largest contributors to global N2O emissions come from East Asia, South Asia, Africa and South America. Emissions from synthetic fertilizers dominate releases in China, India and the US, while emissions from the application of livestock manure as fertilizer dominates releases in Africa and South America. The highest growth rates in emissions are in emerging economies, particularly Brazil, China and India, where crop production and livestock numbers have increased.
However, N2O emissions in Europe decreased in agriculture and the chemical industry. This was due to a combination of factors, including voluntary measures to remove N2O from flue gases in the Nylon industry and the introduction of an emissions trading scheme, as well as agriculture in many Western European countries moving to more efficient use of fertilizer to reduce environmental impacts such as pollution of groundwater and surface water. Policies on nitrogen fertilizer usage were also introduced.
I recommend readers watch Kiss the Ground on Netflix which gives you solutions to the problem (although it is a little scary).
As climate change events increase in number and ferocity, so does climate change risk for businesses and organisations. To remove or control this risk, organisations need to be equipped with the right practical knowledge.
Carbon Training International (CTI) offers courses that give clear direction to understand how to deal with climate change risk.
CTI courses include Strategic Carbon Management, Carbon Accounting, Applied Energy Efficiency, Reducing Fleet Emissions and Carbon Offsetting.
For all courses commencing in October, CTI is offering a 15% discount.
You can easily enrol in one of CTI?s online webinar courses at https://co2ti.com/. Just choose your preferred course and course start date. Extra course dates can be arranged.
The good news: carbon emissions and business costs are linked. The more an organisation reduces its carbon emissions the more it reduces its costs.
Eco-tip for the day ? Shade at home and work
Take advantage of nature. Trees and artificial shade such as wide eaves and external blinds can help prevent the sun from heating up your house. Careful positioning of windows and skylights can also reduce the need to use artificial lighting.
Shade make the premise so much more comfortable in summer and will mean hugh savings on the heat you did not have to shovel back out with an air conditioner.
Share watch ? Hastings Technology Metals (ASX: HAS)
Hastings Technology Metals has unearthed what it describes as ?outstanding? rare earth oxides from drilling at its Fraser?s North and Fraser?s South targets within the Yangibana project in Western Australia.
The company has received numerous ?potentially economic? results from 29 holes out of 30 drilled at Fraser?s North and South. Additionally, Hastings noted the assays included some of the highest-grade results returned at the project since 2014.
Notable assays were 3m at 7.28% total rare earth oxide (TREO) from 8m, including 1m at 18.57% TREO from 8m; 8m at 3.51% TREO from 31m; and 6m at 1.42% TREO from 8m. Hastings chief operating officer Andrew Reid said the results were ?fantastic? and had ?exceeded? the company expectations for the 20,000m drilling program.
He added that almost every drill hole result announced today had intersected economic rare earth grades that could be mineable. ?The exceptionally high grades from Fraser?s South (up to 18.57%) gives us a lot of confidence that we are in a rare earth zone richly endowed with huge potential, particularly given how little exploration it has seen.?
