The initial focus will be on three climatechange science drivers and corresponding questions to be answered during the project’s initial phase: Water Cycle: How do the hydrological cycle and water resources interact with the climate system on local to global scales?
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.,

Heterogeneity as a buffer against climatechange in the Arctic.
A new study co-authored by CSIRO (Australia) scientists Paul Durack and Dr. Susan Wijffels finds evidence that the world’s water cycle has already intensified. The stronger water cycle means arid regions have become drier and high rainfall regions wetter as atmospheric temperature increases. Source: Durack and Wijffels. ºC since 1950.

Much of the regional annual rainfall is recorded in summer.
Rice—which provides nearly half the daily calories for the world’s population—could become better adapted to stresses resulting from climatechange and some catastrophic events through what researchers are calling “symbiogenics”—symbiosis-altered gene expression. 145–230 mya). —Redman et al.
It is increasingly clear that climatechange will have potentially large impacts on the nation’s highways, railroads, waterways, airports and pipelines. In all likelihood, these impacts will increase in the future, so we have to learn how to plan ahead.

An Oak Ridge National Laboratory (ORNL) paper published in Computers & Geosciences outlines a process that might help to determine the relative importance of population increases vs. climatechange. Our work establishes a new method to couple geographic information system data with global climate outputs and statistical analysis.
A new MIT and Caltech study on the impact that global climatechange will have on precipitation patterns concludes that extreme rainfall will increase in the future. The basic underlying reason for the projected increase in precipitation is that warmer air can hold more water vapor.
finds that the sea-level rise is at least partly a result of climatechange. The rise—which may aggravate monsoon flooding in Bangladesh and India—could have future impacts on both regional and global climate. The warm pool has heated by about 1 degree Fahrenheit, or 0.5
The target train passing by The Kelpies —30-meter-high horse-head sculptures depicting kelpies (mythical Celtic water horses which could transform their shape and which were reputed to have the strength of 10 horses and the endurance of many more), in Grangemouth near Falkirk.
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.
Inset (a) shows water demand and losses and supply. The probability of such a severe shortage by then runs as high as one-in-two, unless current water-management practices change, the researchers report in a paper to be published in the American Geophysical Union (AGU) journal Water Resources Research. Rajagopalan et al.
GE and FilterBox x recently signed an agreement to develop integrated de-oiling and water treatment options for Alberta’s oil sands. Specifically, the two companies will work together on heavy oil produced water treatment projects using in-situ thermal methods such as steam-assisted gravity drainage (SAGD). Earlier post.).

The study, from the University of Washington, the University of California Santa Barbara and federal scientists, is published in Nature ClimateChange. The new paper focuses specifically on what this atmospheric circulation means for Arctic sea ice in September, when the ocean reaches its maximum area of open water.
The system will graph lifecycle impact for a range of specified powertrains, for a large number of impact categories: Climatechange [kg CO 2 -eq.]. Depletion of fresh water reserves [m 3 ]. The top sample above shows climatechange impact; the subsequent chart shows human toxicity. Sample results from Carculator.
UCLA and Lawrence Livermore researchers have found that most climate models overestimate the increase in global precipitation due to climatechange. This comparison with observations allowed us to see quite clearly that most models underestimate the increased absorption of sunlight as water vapor increases.
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. —Aldo Steinfeld.

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.
GE is partnering with the University of Alberta (UA) and Alberta Innovates Technology Futures (AITF) on a $4 million CO 2 capture project supported by the ClimateChange and Emissions Management (CCEMC) Corporation. The materials also have the potential to be used as filters for contaminated water.

The people whose business model is to wreck the ecology and the climate and profit from it. These are the people who in the face of science that says we must transition from fossil fuels to renewable energy or destroy the futures of our children and all who come after them, still want to drill for oil that should never be burned.
The study will appear next month in the peer-reviewed journal ClimaticChange Letters. Relying more on natural gas would reduce emissions of carbon dioxide, but it would do little to help solve the climate problem. However, the effects of natural gas on climatechange have been difficult to calculate.
