‘Solar Radiation Modification’ A method deliberated upon by US based scientists and supported by US government talks about reflecting solar radiation over the oceans in order to reduce planet’s temperature and reverse climate change due to soaring temperature. It talks about creating a cloud mist by stratospheric aerosol injection through aeroplanes which successfully reflects back the solar rays back to space . Although there is significant reluctance among the global scientific community about the process due to its unknown effect on land , ecology and ecosystems which are all dependent upon solar radiance for survival. There is a need for further simulations and climate modelling studies to understand the effects of such endeavours on land, water food and health of the planet and its inhabitants. What do you think about it?? Prarthana Borah Himanshu Shekhar Momentum #SolarRadiationModification#SRM#Momentum

Detecting Artificial Greenhouse Gases on Exoplanets: Potential Sign of Technological Life Recent research by University of California, Riverside astrobiologist Edward Schwieterman and his team has unveiled intriguing possibilities in the search for extraterrestrial life: the detection of artificial greenhouse gases on exoplanets. These gases, designed to manipulate planetary climates, could serve as technosignatures indicating the presence of intelligent civilizations capable of terraforming or climate control. Schwieterman emphasizes that while these gases pose environmental risks on Earth due to their potent greenhouse effect, they could be strategically employed by advanced societies to sustain habitable conditions on otherwise inhospitable planets, such as Mars. This concept aligns with ongoing discussions in astrobiology about the potential manipulation of planetary atmospheres to support life. The five proposed artificial greenhouse gases identified by the researchers include fluorinated versions of methane, ethane, and propane, as well as compounds involving nitrogen and fluorine or sulfur and fluorine. These substances, commonly used in industrial processes on Earth, possess exceptionally high global warming potentials, with some like sulfur hexafluoride boasting w...

Methane is more harmful then carbon dioxide in the short term as per NASA. We have plenty of sources of avoidable methane gas .Landfills and waste can produce objectionable odors and landfill gas which can move through soil .collect in nearby areas . The gases produced in landfills like ammonia, sulfides, methane, and carbon dioxide are bad for atmoshphere as well as people living in nearby areas . This is easily avoidable if we treat them in real time .

I am pleased to announce that my first-ever paper, the first "positive" result of my PhD, has just now been published in the Quarterly Journal of the Royal Meteorological Society. Check out the link below if you are interested in understanding whether the marvelous patterns into which trade-cumulus cloud fields organize influence how much they reflect radiation to space. link for the open access: https://lnkd.in/dNDRUtWU #clouds #climate #pattern #trades #radiation #microphysics #PhD #atmospheric #science #atmospheric #physics

Mapping Methane Emissions Across the US: A Visual Story from NASA ? Methane, the sneaky culprit behind climate change , is the second-most impactful greenhouse gas after carbon dioxide (yikes!). But where exactly are these human-caused methane emissions coming from in the US? Lights, Camera, Methane! NASA's amazing Scientific Visualization Studio has created a video that maps these emissions across the US in 2012, aligning with data from the US Environmental Protection Agency What you'll see: This incredible visualization helps us understand the sources and distribution of methane emissions . From agriculture and waste facilities to the fossil fuel industry, the video sheds light on where we need to focus our efforts for reduction. Knowledge is Power! By understanding these emission patterns, we can develop targeted strategies to curb methane and mitigate its impact on climate change Let's work together for a cleaner, greener future! #ClimateChange #MethaneEmissions #NASAClimateChange #Science #Sustainability #ActOnClimate

🛰️ Google Earth Engine (GEE) will host data that MethaneSAT sends back to earth once its up in space. 🌎 Yael Maguire also says that Google will produce a map of oil and gas infrastructure using computer vision, which will be used to find out whose leaky stuff is spewing methane. It will be interesting to see how this compares to existing public maps produced by the likes of Global Energy Monitor, Carbon Trace and the various pay-to-play services out there. Despite methane being responsible for about 30% of global warming, public high-resolution data on the emissions of methane point sources is patchy. Carbon Mapper has done a great job in the US, but flyovers are infrequent, and NASA's EMIT only highlights the very biggest leaks. The most granular and complete data still sits behind paywalls with the likes of Kayrros, which naturally limits access to investigative journalists. We can't wait to get our hands on this data when it comes out and see what stories might emerge. 🕵️ https://lnkd.in/gDNAfEQv

WARMING MARS WITH NANOPARTICES? One-third of Mars’ surface has shallow-buried H2O, but it is currently too cold for use by life. Proposals to warm Mars using greenhouse gases require a large mass of ingredients that are rare on Mars’ surface. However, we show here that artificial aerosols made from materials that are readily available at Mars—for example, conductive nanorods that are ~9 micrometers long—could warm Mars >5 × 103 time smore effectively than the best gases. Such nanoparticles forward-scatter sunlight and efficiently block upwelling thermal infrared. Like the natural dust of Mars, they are swept high into Mars’ atmosphere, allowing delivery from the near-surface. For a 10-year particle lifetime, two climate models indicate that sustained release at 30 liters per second would globally warm Mars by ≳30 kelvin and start to melt the ice. Therefore, if nanoparticles can be made at scale on (or delivered to) Mars, then the barrier to warming of Mars appears to be less high than previously thought.

#todayinsight: PACE Satellite Launch: Unveiling the Clouds' Secrets and the Aerosol Enigma in Climate Science! On February 8th 2024, NASA launched a satellite named PACE into space. It is supposed to investigate the role of aerosols in the climate.  Small things can have big effects, the oceans are filled by a tiny plankton. Through a procedure, they produce a chemical called dimethyl sulfide(DMS). This chemical produces what people refer to as the smell of the sea. When DSM evaporates from sea level through some chemical reactions they produce sulfur aerosols. These aerosols then eventually nest water vapors. The vapors eventually form the clouds. The clouds are a crucial part of life on the planet earth. They bring water from the oceans into the lands. Clouds also reflect parts of sunlight, cooling down the earth. This is the same process that thermal geoengineering proposes to cancel out the warming effect of greenhouse gasses.  Until recently, the ship fuels were extremely unrefined and contained high degrees of sulfur, the smoke from ship funnels emitted sulfur particles. These particles then form a series of clouds, which is called “ship tracks”. Ship tracks are visible in satellite images and indicate the trajectory  of ships movements. Because sulfur is toxic, in 2020, the International Maritime Organization put a limit on the sulfur content of the ship fuels. This new law is controversial among climatologists. Some climatologists believe that the sulfur content in ship fuels had a positive effect as they helped formation of clouds which reflected the sunlight out of earth. Some of them even cite this law as the main contributor to 2023 hot weather. Others of course believe that the effect was not so big. The effect of aerosols is that climate is the main source of uncertainty. This is what produces error bars in climate models and satellite PACE is supposed to make this clear. It is equipped with cameras that are capable of tracking both particles on oceans (namely Planktons) and aerosols in the atmosphere. #globaleconomy #globaltrade Source: Economist https://lnkd.in/dKGJ23UR

According to NASA, methane lasts about 7-12 years in the atmosphere and it contributes an estimated 20-30% of post-industrial warming. The fight against #climatechange demands innovative solutions, and Blue Dot Change is proud to contribute with a nature-inspired cutting-edge approach to remove methane from the #atmosphere. Blue Dot Change leverages a natural process occurring over the ocean where sunlight reacts with chlorine from ocean salt and iron from dust to break down methane. Blue Dot Change mimics and accelerates this process by releasing iron chloride particles into the atmosphere above the ocean, utilising existing commercial ships for efficient deployment. This innovative approach results in reduced atmospheric methane, contributing positively to the global fight against climate change. At lomarlabs, we are focused on catalysing new, environmentally driven technologies and believe this nature-centred approach has the potential to introduce systematic, gradual change in the way we remove methane from the air. We are very excited to work with the Blue Dot Change team and to ultimately help commercialise its technology for our industry. Learn more here: https://lnkd.in/eY6Q2iZn
