“Methane is a short-lived greenhouse gas compared to carbon dioxide. Most emissions, and therefore their warming effect in the atmosphere, occur during the first 20 years after being released, so it’s a good target for fast mitigation of global warming,” Dr Pep Canadell said. So some immediate efforts (budget) should migrate from anti-CO2 to anti-CH4 ? To what extent does this not penalize the medium and long term? There should be a link between the balance between those 2 budgets and the selected horizon for a theoretical « warming minimization » : => Does someone know about any simplified modeling / optimisation results ? Even if obviously over-simplified, should this help, if not exploited too “basically” ? #CO2 #CH4 #methane #warming #globalwarming #climatechange #modeling #optimization #optimisation #modelisation #energytransition

Did you know that the wastewater industry emits nearly twice as much methane as previously thought? Methane (CH4) is a potent greenhouse gas (GHG) with a global warming potential nearly 30 times greater than CO2 - and according to recent studies by Princeton researchers, the wastewater industry emits nearly twice as much CH4 as estimated by The Intergovernmental Panel on Climate Change. In this insight story, we explore how better H2S monitoring and control could hold the key to solving not only odor & corrosion related issues caused by H2S, but also for helping water utilities reduce GHG emissions.

Methane emissions from human activities have increased by 20 per cent in the past two decades. 📈 Methane is one of three core greenhouse gases that contribute to climate change. It has the highest short-term global warming potential, as it holds more heat in the atmosphere. As part of the Global Carbon Project, we've worked with international research partners to release the Global Methane Budget 2024. It covers 17 natural and anthropogenic (human-induced) sources and shows that methane has increased by 61 million metric tonnes per year. Read the full story: https://lnkd.in/gdredZvT

Since 2007, methane emissions have surged and are now accounting for 1/3 of global warming that’s intensifying the current climate emergency; according to International Energy Agency. This surge has alarmed scientists, who view it as the most significant barrier to staying under the critical threshold of 1.5 degrees C in global temperature rise. This fact seems to be linked to increased global temperatures spurring further methane release from wetlands. A big portion of emissions comes from man-made sources where 40% of it comes from human agriculture, 37% from energy, 20% from waste, and 3% from other sources. By tackling waste as a source we can reduce methane emissions which is now more critical than ever.

Agriculture emits three key greenhouse gases that contribute directly to climate change: Carbon dioxide (CO₂), Methane (CH₄), and Nitrous oxide (N₂O). Much has been written about the former two, but N₂O, also known as “laughing gas” and the main man-made substance damaging the planet’s protective ozone layer, often attracts the least attention, despite being nearly 300 times more potent than carbon dioxide. But a new paper has warned that N₂O emissions have grown 40% between 1980 and 2020, greatly accelerating climate change and threatening efforts to keep global warming to internationally agreed limits. “The current growth rate of atmospheric N₂O is likely unprecedented to the ice core records of the past 800,000 years,” it said. https://lnkd.in/d5Gy5w9V

Did you know that although Carbon dioxide (CO2) is the most common GHG, it is not the most powerful in causing global warming? It is estimated that 1 tonne of Hydrofluorocarbons (HFCS) is the equivalent to over 1,800 tonnes of CO2, while 1 tonne of methane (CH4) is estimated to be the equivalent of around 25 tonnes of CO2 in terms of its impact as a greenhouse gas. I thought you should know! 

The world’s nations would need to cut their greenhouse gas emissions by a lot. And even that wouldn’t stop all global warming. For example, let’s say we wanted to limit global warming to below 2°C. To do that, the IPCC has calculated that annual greenhouse gas emissions would need to drop at least 40 to 70 percent by midcentury. Emissions would then have to keep falling until humans were hardly emitting any extra greenhouse gases by the end of the century. We’d also likely need to pull some carbon dioxide out of the atmosphere. The blue line below shows the path emissions would have to take to for a better-than-even chance of staying below 2°C

Let’s talk about greenhouse gases (GHGs) In the previous post, we discussed global warming and how greenhouse gases contribute to creating the global warming crisis. Now, let's discuss greenhouse gases in more detail. Greenhouse gases (GHGs) are a group of gases present in the Earth's atmosphere that have the ability to trap heat and contribute to the greenhouse effect, leading to global warming and climate change. The most common greenhouse gases include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases. These gases are released into the atmosphere through natural processes such as volcanic eruptions and decomposition, as well as human activities like burning fossil fuels, deforestation, and industrial processes. The increasing concentration of greenhouse gases in the atmosphere is causing the Earth's temperature to rise, resulting in changes to weather patterns, rising sea levels, and the disruption of ecosystems. Efforts to reduce greenhouse gas emissions and mitigate their impact are crucial for the sustainable future of our planet. #greenhousegases #globalwarming

CARBON STORAGE. As the world struggles to deal with the growing problems caused by climate change, carbon storage has become an important way to lessen the bad effects of too much carbon dioxide (CO2) emissions. Carbon storage, which is also called carbon sequestration, is the process of capturing and safely storing CO2 emissions from power plants and factories so that they don’t get released into the air. This all-around approach is very important for lowering the amount of greenhouse gases in the air and stopping global warming.
