Last week, MIT’s “Technology Review” reported that a small startup firm is proposing to spray reflective aerosols in the stratosphere commercially as a climate corrective. First, the cooling from the reflective materials they will inject, for which they are already selling carbon credits, charging $10 per gram of SO 2 released (!)
I had reason to be reviewing the history of MSU satellite retrievals for atmospheric temperatures recently. It’s a fascinating story of technology, creativity, hubris, error, imagination, rivalry, politics, and (for some) a search for scientific consilience – worthy of movie script perhaps?
Solar geoengineering offers a way of mitigating the effects of global warming by reflecting incoming sunlight back into space – thereby cooling the Earth. One way of doing this is to inject aerosols into the atmosphere. To maintain a 1 °C cooling effect, this would cost about $43bn per year to operate. Longer lasting.
To give the Commission credit where due — and it is due in many places — on one point closely related to these projections, they were uncommonly and admirably frank: Noting the risks and the stark tradeoffs posed by aerosol pollution in the lower atmosphere. Current and coming advances in carbon-free technology will help, of course.
Addressing this serious problem using existing technologies is a key part of the United Nation’s sustainable development goals – with the organization declaring that everyone should have access to five litres of safe drinking water every day. The lack of access to safely managed drinking water now affects some 2.2 billion people worldwide.
Responsible for 12 percent of all US global warming emissions from human activities, methane traps significantly more heat per molecule than carbon dioxide, making it 86 times more harmful for the first 20 years after it is released into the atmosphere. VY: Clean energy sources will be absolutely pivotal for an equitable and reliable grid.
Does the climate keep warming, stay the same, or even cool? First, after carbon dioxide emissions cease, atmospheric carbon dioxide levels begin to decrease, as they are absorbed by natural processes and sinks in the oceans and on land. But what happens when we achieve the goal of zero carbon dioxide emissions from human actions?
Human activity adds more than 50 gigatons of carbon dioxide to the atmosphere each year. New Solid Carbon technology might be able to lock climate-warming carbon dioxide below ocean bedrock. Basalt is a porous rock formed from cooling lava. That means the Solid Carbon technology could be used at sea anywhere.
Specifically, we found that photovoltaics can significantly warm the urban environment during the day, but typically cool the urban environment at night. Other studies, particularly modelling studies, had previously suggested a daytime cooling effect of photovoltaics. What research did you include in your study?
This is equivalent to nearly 8% of the mass of all water vapour in Earth’s atmosphere. The models show that afforestation and a more reflective surface cools the land, which dampens sea breezes and reduces the movement of water vapour from sea to land. Changing albedo. Strengthening sea breezes.
Many materials display superconductivity when they are cooled to low temperatures, and the phenomenon was first observed in 1911 in solid mercury, which has a superconducting transition temperature T c of 4.2 million atmospheres) than other so-called “superhydrides”. Superconductivity in cerium hydrides.
All of that is changing – the price is dropping as the technology improves, cheaper and more efficient catalysts and processes are being invented, and efficiency and size are improving. Governments are providing incentives, and the industry is progressing. Here’s my argument: Scientists now agree that we can’t stay anywhere near 1.5°C
“Natural gas”, also known as methane gas or fracked fossil gas, is a potent greenhouse gas that pollutes the environment and causes climate change when it is burned and when it escapes into the atmosphere during extraction, production, and transportation. But Enbridge is misleading these people, and trying to lock in more Ontarians to gas.
That is because before it can push the envelope of what science and space technology can achieve, it had to first overcome a dangerous deep-space unpacking: its 6.5 If it continues to succeed without a hitch, it should transform astronomy – all thanks to several technological marvels that make the JWST a unique and powerful instrument.
Simply put, gases that trap heat in the atmosphere (. Yes, water vapor is the most abundant GHG in the atmosphere, but it is a different animal and water vapor does control Earth’s temperature but, there is never a change in the amount of water on Earth.). In 2020, carbon dioxide accounted for about 79% of all U.S. emission trends.
The National Heat Strategy The Strategy is authored by the National Integrated Heat Health Information System (NIHHIS), an interagency initiative coordinating work across two dozen federal agencies and led by the Centers for Disease Control and the National Oceanic and Atmospheric Administration. A draft rule from the U.S.
In research, Tracy has developed water treatment technology, strategies for sustainable design, aquaponics for space travel, and citizen science programs with over 1.6million users to obtain publicly available environmental data.
Satellites, for example, are used in meteorology to track weather systems and to monitor atmospheric fronts to predict what the weather will do next. Known as ENSO, they are opposite effects of the same process and are defined as an oscillation (a variation in magnitude) between the temperature of the atmosphere and the ocean.
Can climate resilience technology help businesses protect people and property from such devastating wildfire events? This environmental spectacle occurs when a large region of extremely hot air, created by a wildfire interacts with cooler air higher up in the atmosphere. Is climate change making ‘firenadoes’ more likely?
This article focused on PFAS remediation but we also have some cool funded efforts to develop instrumentation to improve the speed at which the DoD can conduct site characterization and determine if and how much remediation needs to be done. What are the sources of PFAS in the atmosphere.
UNDO ’s focus on enhanced rock weathering developed from the realization that conventional strategies, like mass tree planting, could not alone counter the massive amounts of carbon dioxide in the atmosphere. Basalt is formed by cooling lava, so wherever you have volcanic activity, you find basalt. It is also common.
Eventually, CO2 levels in the atmosphere would return to 350 ppm. No, current technologies and future inventions will be needed and welcomed. Back to 2017, I had loved listening to famous environmentalist Paul Hawken present his book Drawdown. Solar and wind are already replacing coal and fossil gas for electricity generation.
vital for new technologies that all of us use every day from solar panel technology to wind turbine, engineering design, and the creation of new alloys and polymers. Satellite Technology : Without satellites, we would not know as much about our planet as we would have done (16). This is both a theoretical and an applied science.
Mill 19 not only boasts a record-setting rooftop solar array and numerous energy- and water-saving features, but also houses companies that are leading the way in developing transformative technologies that are redefining our region,” said Dr. Donald F. Smith, president of Regional Industrial Development Corporation.
A fortnight after calamitous wildfire swept across the Los Angeles region , forecasters are warning of four days of terrible flooding in southern and northern California caused by an approaching atmospheric river. They produce no carbon emissions that cause climate change, and can be air-cooled. Western N.C. ever produced.

Residents of notoriously polluted New Delhi, where half of the population lacks access to air conditioning, describe soaking in contaminated waters to stay cool. . Such events are becoming more common as Earth’s atmosphere continues to warm. Cooling monsoon rains will moderate temperatures, but not for another month.
OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster. Atmospheric concentrations. Climate impact. W/m 2 from elevated CO 2.
SG would cool the Earth, temporarily and imperfectly offsetting some of the climate effects of elevated greenhouse gases, by reflecting a bit (around 0.5% The way to do this that now looks most promising would be to spray a fine mist of reflective aerosols in the upper atmosphere. to 1%) of incoming sunlight.
Our atmospheric scientist Dr. Yvonne Boose recently hosted a unique webinar session to explore the air quality reporting challenges presented by wildfires, alongside practical solutions for businesses looking to protect themselves and people from wildfire impact. When everything is dry, there is less evaporation which means less cooling.
As air sunk through the atmosphere, it got squeezed and heated. Extreme heat is not just an abstract notion: if we can’t cool our bodies enough, we’re in danger of neurological failure, organ failure and even death, with the risks highest for children and the elderly.

Atmosphere The gaseous envelope surrounding the Earth. The dry atmosphere consists almost entirely of nitrogen (78.1% The dry atmosphere consists almost entirely of nitrogen (78.1% In addition, the atmosphere contains water vapor, whose amount is highly variable but typically 1% volume mixing ratio.
From freezer upgrades in labs to geothermal heating and cooling at Johnstown, the winner will move the University of Pittsburgh toward its carbon neutrality goal. Excessive food waste and dying soils are having a profoundly negative global impact, notably in creating extreme atmospheric carbon levels. Lenz, who both hire Pitt alumni.
When organic waste is packed into landfills, a lack of aeration (introducing oxygen) renders it unable to decompose, causing it to emit larger quantities of greenhouse gases into the atmosphere. Jamie Blanchard-Poling, the Compost Queen, stands next to a Gortex cover, a relatively new technology that allows for more efficient composting Aug.
When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,
In 1970 in the Boston Globe newspaper, there was a scientist from the atmospheric research in Boulder, Colorado predicted that an ice age would be upon us by the 21st century. He also predicted that in the electric generation demands for cooling water will boil dry the entire flow of rivers and streams in the continental United States.
Technology and Adaptation. The Colorado River water that cooled the plant is part of a broader legal impasse. Technology and Adaptation. utilities have been slower to adopt the energy- and emissions-saving technologies than those in other parts of the world. Colorado River Basin Reaches Pivotal Moment. Covid and WASH.
The Trump EPA had invoked the major questions doctrine and the Agency’s past interpretation of technology-based standards under section 111 of the Clean Air to find that EPA could not rely upon switching methods of power generation to establish an emissions reduction budget under a cap-and-trade program.
First, some background drawing from my previous posts: Solar geoengineering (SG) is a set of technological interventions in the climate system being discussed, which could provide quick, temporary, imperfect relief for severe near-term climate change impacts. Most of these bills include some form of prohibition.
Your morning newscasters or social media feeds typically give you “ stay cool ” tips in advance of a heat wave, or a hurricane warning for your coastal city may show you maps or list areas under mandatory evacuation order due to projected dangerous storm surge. NOAA belongs to us, is paid by us, and cannot be taken away from us.
These dire circumstances have not yet come to pass, but the Trump administration’s extensive and ongoing attacks on science, including further cuts to the National Oceanic and Atmospheric Administration (NOAA) threatened in the Presidents skinny budget , make it a likely scenario during this year’s Danger Season.
Energy conservation can take a lot of different forms, starting with retrofitting existing structures with insulation and more efficient heating and cooling. Commercial buildings could benefit from new technologies using artificial intelligence to control their heating and cooling systems.
The Senate Commerce, Science and Transportation Committee advanced the nomination of Jainey Bavishi to be the assistant secretary of oceans and atmosphere at the National Oceanic and Atmospheric Administration, the second-most senior position at NOAA. The United States needs a department of technology and science policy – Nature.
This latest report looks at mitigation — or what the world can do to stop pumping greenhouse gases into the atmosphere. Countries will also have to extract carbon dioxide from the atmosphere to keep global warming in check. degrees or try to cool the planet back down through the massive use of CDR. Capturing carbon is a must.
