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 ClimateChange suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climatechange due to the combined impacts of lower summer river flows and higher river water temperatures.

Ford Motor Company is the first automaker and one of several companies taking a leadership position in joining the Water Disclosure Project , which will establish a water disclosure protocol for companies around the world and promote conservation and stewardship. For the past decade, Ford has made it a priority to conserve water.
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?
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. A global warming potential of 11.6 Sand et al.

Heterogeneity as a buffer against climatechange in the Arctic.
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. degrees F (0.1-0.2
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.
The National Research Council of the US has released a report examining the potential for climatechange to pose or to alter security risks for the United States over the next ten years. It also emphasizes climate-driven security risks that call for action within the coming decade either to anticipate or to respond to security threats.
The smartest scientists on the face of the planet, the ones studying climatechange and global warming, are mad as hell and they’re not going to take it any more. But the scientists now know that we’re NOT going to save our children from that hell and high water that’s coming their way.
This article shows that including offsets in climatechange legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,
A new report commissioned by the World Bank, and prepared by the Potsdam Institute for Climate Impact Research (PIK) and Climate Analytics, provides a snapshot of recent scientific literature and new analyses of likely impacts and risks that would be associated with a 4 °C global warming within this century.
It makes an important contribution to the scientific understanding we have of the role of aviation for climatechange—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement. This new study is based on a thorough review of a decade of research on aviation emissions.
An international team of researchers has confirmed the presence of a deep-reaching ocean circulation system off Iceland—the North Icelandic Jet (NIJ)—that could significantly influence the ocean’s response to climatechange in previously unforeseen ways.

Global carbon dioxide emissions from burning fossil fuels have increased by 49% in the last two decades, according to the latest figures from the Global Carbon Project. Published in the journal Nature ClimateChange , the new analysis shows fossil fuel emissions increased by 5.9% parts per million. Canadell and Michael R.
It is increasingly clear that climatechange will have potentially large impacts on the nation’s highways, railroads, waterways, airports and pipelines. Right now the climate models are more accurate at the global and regional scale, but they are not capable of predicting the local effects that planners need.
A new MIT and Caltech study on the impact that globalclimatechange 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.

In the CalNex 2010 study outlined here, NOAA researchers are studying several issues at the heart of the coupled air quality and climatechange problems.
UCLA and Lawrence Livermore researchers have found that most climate models overestimate the increase in global precipitation due to climatechange. Conveniently, this quantity can be measured from space, allowing the team to assess how well the models capture the physics controlling changes in global precipitation.

In a new study, KPMG International has identified 10 “megaforces” that will significantly affect corporate growth globally over the next two decades. —“Expect the Unexpected: Building Business Value in a Changing World”.
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 globalclimate. Global sea-level patterns are not geographically uniform. The Indo-Pacific warm pool.
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. This interconnectedness also increases the amount of risk at each step of a global supply chain.
