Living the 1.5 Degree Lifestyle Corporate Knights

"...It’s harder when everyone wants more stuff, and the jobs all depend on us buying it. So, the only strategy anyone can think of is to produce more carbon-efficient stuff, to build electric cars instead of gasoline-powered, to burn natural gas instead of coal, to make more wind turbines and solar panels, and to dream of nuclear reactors, carbon capture and storage, and hydrogen..."

Lessening the cost of strategies to reach the Paris Agreement

"...Five researchers shed new light on a key argument to reduce greenhouse gases (GHG): they provided the first economic analysis of conversion factors of other GHG like methane into their CO2 equivalent in overshoot scenarios. Although the United Nations Framework Convention on Climate Change (UNFCCC) considers settling for one value of reference (known as "Common Metric") to make this conversion among the Paris Agreement, the models presented here show the economic advantage of flexibility between various factors of conversion. "A key notion in the UNFCCC is to reduce GHG emissions in the least costly way so as to ensure global benefits" highlights Katsumasa Tanaka, primary author of the Science Advances study..."

Conversations That Matter: Is all methane created equal?

"...Haworth, however acknowledges that, “cow produced methane is not the big culprit in global warming potential, it is by far and away the fossil fuel industry and in particular shale gas production that is of the greatest concern. ” The reason Haworth says that shale gas produced methane is a more potent greenhouse gas because of the carbon isotope within it..."

Saskatchewan Trucking Association criticizes Supreme Court ruling on carbon tax

"...The federal fuel charge came into effect on April 1, 2019 for several provinces including Saskatchewan. It is laid out in Greenhouse Gas Pollution Pricing Act. The rate reflects a carbon pollution price of $20 per tonne of carbon dioxide equivalent in 2019, rising by $10 per tonne annually until it reaches $50 per tonne in 2022..."

Carbon-neutral 'biofuel' from lakes

"...Methane from lakes and water reservoirs makes up about 20% of global natural methane missions. "That would theoretically be enough to meet the world's energy needs," says Maciej Bartosiewicz, a postdoc in the Department of Environmental Sciences of the University of Basel. Lakes continuously absorb CO2 from the atmosphere through the growth of phytoplankton..."

The race is on, but cooling industry needs to accelerate net zero efforts

"...Paris, Nairobi, London, 29 March 2021 - Five major cooling suppliers are racing to net zero but they represent fewer than ten per cent of the 54 suppliers assessed in a new report, meaning the industry has a lot of work to do to catch up on climate action and reduce pollution from the sector, currently estimated at 7% of global greenhouse gas emissions..."

Destruction of the Amazon forest very likely contributes to global warming, as accurately described in The National Geographic a

"...The recent study explored how non-CO2 climate drivers respond to local changes (deforestation, dam construction, and cattle ranching) and global changes (warming and drying of soil, wetlands, and biomass). The authors concluded that current warming from non-CO2 drivers, especially methane and nitrogen oxide, in the Amazon Basin “largely offsets—and most likely exceeds—the climate service provided by atmospheric CO2 uptake”, as accurately described in the National Geographic article. The Amazon rainforest plays a key role in slowing the pace of global warming as it absorbs large quantities of carbon dioxide from the atmosphere..."

Gold-phosphorus nanosheets catalyzes nature gas to greener energy selectively

"...Advances in hydraulic fracturing technology have enabled discovery of large reserves of natural gas which primarily contains methane, which is mainly burned directly and causing global warming potentially. Upgrading methane to greener energy such as methanol through aerobic oxidation is an ideal way to solve the problem and remain 100% atom economy..."

Human activity caused the long-term growth of greenhouse gas methane

"...Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2). Its concentration in the atmosphere has increased more than twice since the preindustrial era due to enhanced emissions from human activities. While the global warming potential of CH4 is 86 times as large as that of CO2 over 20 years, it stays in the atmosphere for about 10 years, much shorter than more than centuries of CO2..."

Applying compost to landfills could have environmental benefits

Low oxygen levels in lakes and reservoirs may accelerate global change

"...Because of land use and climate change, lakes and reservoirs globally are seeing large decreases in oxygen concentrations in their bottom waters. It is well-documented that low oxygen levels have detrimental effects on fish and water quality, but little is known about how these conditions will affect the concentration of carbon dioxide and methane in freshwaters..."

'Oasis effect' in urban parks could contribute to greenhouse gas emissions

"..."Because of the oasis effect, when we irrigate our urban parks at night, we lose vast amounts of water and we see increased carbon dioxide emissions, which could lead to higher global warming potential," says Vivoni. "This has important implications for water conservation and greenhouse gas emission management in desert cities such as Phoenix. "..."
