of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. 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.
Projected extreme temperatures under climatechange are predicted to reduce average yields for several of the United States’ major crops. These changes in productivity would drive farmers to change crops and move into new areas. Farmers are particularly exposed to the problems of climatechange.
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.,
The review is the latest product of WHO’s Health in the Green Economy initiative, which is considering available evidence on health impacts from climate mitigation strategies for key economic sectors, as reviewed by the UN’s Intergovernmental Panel on ClimateChange. million deaths annually are due to physical inactivity.

The Administration said the United States will submit its 2025 target to the Framework Convention on ClimateChange as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. launching a new track on the interaction of energy and water (the energy/water ‘nexus’).
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.
According to the R&D engineer of this project, hydrogen fuel cell construction vehicles have five important advantages: The realization of zero pollution with only water and heat being discharged. The latter is the first hydrogen-powered mixer truck in the world.
To solve the climate crisis, we need to cut this in half by 2030, and get to zero by 2050. However, there’s a shortage of roboticists tackling climatechange, due to a lack of awareness of necessary and urgent applications. Surprisingly, many founders I talked with echoed the shortage of roboticists in climate tech.
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.
And so it is that I resigned from my position as Director of Strategic Partnerships and Public Affairs for CBS EcoMedia effective the first of this month and I will now be devoting my full time to working on climatechange response with the South Bay 350 Climate Action Group, the South Bay Bicycle Coalition and 350.org.
The people whose business model is to wreck the ecology and the climate and profit from it. They know full well what the climate models predict based on a continued burning of their product. . They know that the work they do contributes every day to the wrecking of our climate and all the hell and high water that goes with that.
announced its next environmental sustainability strategy—PLANET 2050—which includes science-based goals that meet or exceed the goals in the United Nations Paris agreement on climatechange. Reduce absolute water consumption in facilities and operations by 30%. Cummins Inc.
Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.
The post How does climatechange impact groundwater quality? Researchers have investigated how global warming is affecting groundwater quality and what it means for humanity and the environment. appeared first on Innovation News Network.

SMRs are a game-changing technology with the potential to play a critical role in fighting climatechange, and rebuilding our post COVID-19 economy. Molten salts are thermally very stable, making them superior coolants compared to water. —Hon. Seamus O’Regan, Minister of Natural Resources.
The project concerns the production of hydrogen at scale from offshore floating wind in deep water locations. The concept consists of a large-scale floating wind turbine (nominally 10 MW) with an integrated water treatment unit and electrolyzers for localized hydrogen production. Contract value: £7.48 million (US$9.7 million (US$3.6
Researchers in Europe led by a team from ETH Zurich have designed a fuel production system that uses water, CO 2 , and sunlight to produce aviation fuel. We are the first to demonstrate the entire thermochemical process chain from water and CO 2 to kerosene in a fully-integrated solar tower system. Zoller et al.
City Council, board members of the Los Angeles Department of Water and Power Commission and long term colleagues from the climate justice action community to be part of a historic announcement. ” – this means that mega-polluting, constantly climate-killing, fossil fuel Chevron must go too.
This is an important development because there is little time available to reduce CO 2 emissions sufficiently to avoid the worst effects of climatechange. 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.
We need more aggressive cuts in emissions to get us anywhere near the pathways that limit the worst impacts of climatechange. California must continue its strong climate leadership if we are to have any hope to reduce our greenhouse gas emissions in time to keep the climate safe, which is vital, because….

The day reminds us of the need to protect our planet and its ecosystems against the worsening climate crisis. The climate crisis is threatening people across the world, as well as every species of animal and plant life. Climatechange is a global societal crisis that is causing devastating consequences.
By creating carbon-neutral gasoline from CO 2 captured from the air, Prometheus Fuels allows the climate impact of today’s internal combustion engines to be massively reduced immediately. The conversion of CO 2 to fuels in these inexpensive water-based systems has shown high faradic efficiencies for reduction of CO 2.

That’s been the strategy of SCE’s man-on-the inside of the California State Assembly, Steven Bradford, who says he “ resents the implications ” that he is carrying water for his former employers and current campaign contributors. .
I’ve had it proven to me time after time after time over the last five years as Councilman Powell stood up strong on bicycle issues, on health issues, on climate issues, on water issues, on fossil fuel issues, on safety issues. And no surprise to anyone who knows Wayne Powell, I was completely wrong about him. Right on, Wayne!
A study published earlier this year in the journal Nature ClimateChange that cast doubt on whether biofuels produced from corn residue could meet federal mandates for cellulosic biofuels to reduce greenhouse gas emissions by 60% compared to gasoline ( earlier post ) has drawn critical response published as correspondence in the same journal.
This reactor’s innovative features include the use of natural circulation and passive cooling systems, which are designed to cool the nuclear fuel under all conditions without the need for external power or external water supply for extended periods. A single SMR of about 300 megawatts in size can prevent between 0.3

These great masses store enough water to raise global sea level by 65 meters should they melt entirely. Although neither ice sheet is expected to melt completely anytime soon, their incredible scale makes even small changes consequential for the future of our planet. Thomas Teisberg, an electrical engineering Ph.D.
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. Countries meet their needs for goods and services through domestic production and international trade.
The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years.
