Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.
Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.
billion people in 2050 will live in water-stressed areas. The researchers also expect about 1 billion more people to be living in areas where water demand exceeds surface-water supply. A large portion of these regions already face water stress—most notably India, Northern Africa and the Middle East. Schlosser, C.A.,
A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures.

The results of a new analysis by the International Council on Clean Transportation (ICCT) show that, when combined with a trend toward higher methane leakage and combustion slip, there is no climate benefit from using liquefied natural gas (LNG) as a marine fuel—regardless of the engine technology. First, it contains very little sulfur.
The project, called Accelerated Climate Modeling for Energy ( ACME ), is designed to accelerate the development and application of fully coupled, state-of-the-science Earth system models for scientific and energy applications.

A study led by Norwegian climate center CICERO has found that the global warming effect of leaked hydrogen is almost 12 times stronger than that of CO 2. Unlike exhaust from burning coal and gas that contains CO 2 , burning hydrogen emits only water vapor and oxygen. The climate effects of hydrogen have been an under-researched topic.

Resources.
The life-cycle water consumption of fuel cell electric vehicles using hydrogen produced from natural gas with steam methane reforming is almost 50% less than the life-cycle water consumption of conventional internal combustion engine vehicles using gasoline, according to a study by researchers at Argonne National Laboratory (ANL).
Based on the interim results of a new study, MIT researchers are warning smaller nations to proceed with caution in pursuing the development of their natural gas resources. While natural gas is often cheaper than oil and gives off fewer emissions, developing the resource comes with risks, especially for smaller nations.

Among the transportation-related elements of US President Barack Obama’s new climate action plan, which he is outlining today in a speech at Georgetown University, is the development of new fuel economy standards for heavy-duty vehicles post-2018. Preparing the US for the impacts of climate change. Earlier post.).
Projected extreme temperatures under climate change are predicted to reduce average yields for several of the United States’ major crops. The extent of these regional changes in agricultural productivity and how they influence future cropping decisions is a central question for the risks of climate change for agriculture and food security.
earlier post ), a new study by a team at Environmental Defense Fund finds that the climate impact of hydropower facilities varies widely throughout the world and over time, with some facilities emitting more greenhouse gases than those burning fossil fuels. They also estimated emissions caused by flooding the reservoir.
The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climate change [kg CO 2 -eq.]. Depletion of fossil energy resources [kg oil-eq.]. Depletion of fresh water reserves [m 3 ]. Depletion of metal resources [kg iron-eq.]. Terrestrial toxicity [kg 1,4-DC.-eq.].
This is an important development because there is little time available to reduce CO 2 emissions sufficiently to avoid the worst effects of climate change. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2. to C 2 fuel products such as ethanol.
A schematic model showing the links between climate events and outcomes of national security concern, highlighting the roles of exposure and vulnerability. The National Research Council of the US has released a report examining the potential for climate change to pose or to alter security risks for the United States over the next ten years.
The first large-scale study of the risks that countries face from dependence on water, energy and land resources has found that globalization may be decreasing, rather than increasing, the security of global supply chains. As a result, countries place pressures on natural resources both within and beyond their borders.
The study also found that shows that water use for algae cultivation is much less if algae are grown in the US regions that have the sunniest and most humid climates: the Gulf Coast, the Southeastern Seaboard and the Great Lakes. The paper is published in the journal WaterResources Research.
Aviation climate change impacts pathway. An an example, they point out that an SPK fuel option with zero life cycle GHG emissions would offer a 100% reduction in GHG emissions but only a 48% reduction in actual climate impact using a 100-year time window and the nominal climate modeling assumptions in the paper.
The findings, published in the Proceedings of the National Academy of Sciences , demonstrate that phase can be a key regulator of the reactivity of atmospheric SOM particles, and may call for a revision of regional and global climate models. In the atmosphere, the particles of ?-pinene In dry conditions, they solidify without crystallizing.

This latest version of WATER allows, for the first time, biofuels manufacturers to analyze water consumption associated with use of cellulosic feedstocks such as residue left from lumber production and other wood-based resources.
It may not sound like a phenomenally large amount except the water and the river is already over-allocated. The present study narrows in on three key regions for water managers—the Colorado River headwaters; the greater California-Nevada region; and Texas, which gets nearly all of its water from within state borders.
We are committed to the economical use of resources and therefore want to keep the environmental impact of our production as low as possible. Approximately 70 percent of Audi Hungaria’s heat requirements are already covered by climate-neutral, geothermal energy. Since then, we have been working constantly to reduce it further.

This would increase the annual carbon emission to somewhere between 380 and 920 Mt CO 2 e by 2020 depending on water management practices and the extent of plantations. Despite increasing awareness of climate change in that period, the rate of peat destruction was higher in this last 3 year period than ever before. Miettinen, J.,
The new study used tree-ring data and other climate records to identify a drought period unmatched in severity by the current drought or other ancient droughts. The ongoing Colorado River Basin drought has extensive impacts throughout the West, including water shortages for homes and crops and decreased generation of hydroelectric power.
Evapotranspiration (ET) refers to the sum total of water lost while the plant is growing, either from evaporation through the plant stem itself (a process called “transpiration”), or from water evaporated off of the plant’s leaves or the ground. —Hamilton et al.
Formation of cirrus clouds depends upon the availability of ice nuclei to begin condensation of atmospheric water vapor. Cirrus clouds influence global climate, cooling the planet by reflecting incoming solar radiation and warming it by trapping outgoing heat. A paper on their results is published in the journal Science.

The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2. 2020.01.002.
An important consideration of solar-electrolysis in the context of climate mitigation is the enormity of upscaling required—both at the global scale with respect to the investment, land area, materials, and embodied energy; and at the project scale with respect to the potential localised impacts of gigawatt scale plants.
UBQ is a patented novel climate-positive material created by Israeli startup UBQ Materials that can substitute conventional plastic, wood and concrete in the manufacturing of everyday products. By diverting household waste from reaching landfills, UBQ prevents the emission of methane, ground water leakage and other toxins.
