Coverage of nitrous oxide since December 23, 2022.

‘No end in sight’ to rising greenhouse gas emissions: World Meteorological Organization

"...Last year, global averaged concentrations of the most important greenhouse gas - carbon dioxide (CO2) - were a full 50 per cent above the pre-industrial era, marking a first, and continued to grow in 2023. Going the wrong way Methane concentrations also grew and levels of nitrous oxide, the third main gas, saw the highest year-on-year increase on record from 2021 to 2022. “Despite decades of warnings from the scientific community, thousands of pages of reports and dozens of climate conferences, we are still heading in the wrong direction,” said Petteri Taalas, the WMO Secretary-General..."


Carbon pricing in Canada: What it is, what it costs and why you get a rebate

"...In 2018, Parliament passed the Greenhouse Gas Pollution Pricing Act, which established the legal mechanism under which the federal government requires provinces and territories to either establish a levy on greenhouse gas emissions or adopt the federal system. The legislation was first applied as of April 1, 2019..."


FOREST INK: Carbon-neutral agriculture an option

"...Biochar is described as the New Black in reference to the importance of fossil fuels in industrial agriculture and the ongoing need to become carbon neutral. Management methods alone will not pave the way for climate-neutral food production. More research is needed, and pyrolysis of straw into biochar could prove to be part of the solution since it has the potential to reduce greenhouse gas emissions and at the same time increase the soil’s organic carbon content..."


How farmers can break free of their synthetic fertilizer addiction

"...But making and applying all that synthetic fertilizer is unsustainable. The production of synthetic fertilizers alone, before farmers even sprinkle the stuff on their fields, requires copious quantities of natural gas (much of which comes from fracking, at least in the U. S..."


As ocean oxygen levels dip, just think about the poor fishies

"...Researchers complain that the oxygen problem doesn’t get the attention it deserves, with ocean acidification and warming grabbing the bulk of both news headlines and academic research. Just this April, for example, headlines screamed that global surface waters were hotter than they have ever been — a shockingly balmy average of 70 F. That’s obviously not good for marine life..."


Green light for global greenhouse gas tracking network

"...According to WMO, between 1990 and 2021, the warming effect on our climate from the main greenhouse gases, carbon dioxide, methane and nitrous oxide, rose by nearly 50 per cent..."


Human, economic, environmental toll of climate change on the rise: WMO

"...WMO Secretary-General, Prof. Petteri Taalas, said that amid rising greenhouse gas emissions and a changing climate, “populations worldwide continue to be gravely impacted by extreme weather and climate events”. He stressed that last year, “continuous drought in East Africa, record breaking rainfall in Pakistan and record-breaking heatwaves in China and Europe affected tens of millions, drove food insecurity, boosted mass migration, and cost billions of dollars in loss and damage..."


‘Exceptional’ surge in methane emissions from wetlands worries scientists

"...Meanwhile, a separate study – also published in Nature Climate Change – finds that global warming is also affecting wetland emissions of carbon dioxide and nitrous oxide..."


The way we eat could add nearly 1 degree of warming by 2100

"...FILE - A truck unloads organic waste to be used for composting at the Anaerobic Composter Facility in Woodland, Calif. , on Nov. 30, 2021..."


Weighing the harm of gasoline against lithium

"...Lithium versus gasoline per carMy first graphic compares the amount of lithium required for each new BEV to the amount of gasoline required for each new internal combustion engine car (ICEV). What people are reading Sunny times are over — it’s time for progressive Canadians to own this angry era By Jen Hassum | Opinion | February 7th 2023 The CCP study found that the average new BEV bought in the United States requires eight kilograms of lithium. That's the orange bar on the left of the graphic..."


2022 Year in Review: Amid global turmoil, UN doggedly pursues international climate agreements

"...Climate and EnvironmentDespite strong evidence that human activity played a role in catastrophic weather events, and the emergence of a fuel crisis sparked by the war in Ukraine, greenhouse gas emissions continued to rise. Nevertheless, the UN kept the climate emergency high on the international agenda, reaching major agreements on financing and biodiversity..."
