It's the latest publication from James Hansen NASA's fiery climate change scientist who is retiring on Wednesday after 46 years with the space agency.
The paper does acknowledge the serious health and environmental concerns related to storage of nuclear waste.
The paper has been accepted for publication in the journal Environmental science & Technology and it comes in the same week that Hansen 72 said he will retire.
He is respected a widely climate researcher but in the past several years has become much more than a scientist becoming involved in climate protests and even getting himself arrested a few times.
He unapologetically beats the drum for human-caused climate change and its current effects. Even climate scientists have said he can be alarmist
and he has rankled environmental groups with his support for nuclear power. With his departure from NASA the climate research community loses one of its most vocal members
and the climate-denialists lose one of their favorite punching bags. But Hansen told the New york times he plans to continue his activism after he retires including taking on the federal government in lawsuits.
As a government employee you can't testify against the government he told the Times.
The safety of nuclear energy is equal to flying an airplane. On a typical day life is good
and the world is sweet but when an airplane falls from the sky and you are in it it only ends in as a gigantic disaster.
The same is true of nuclear energy just ask Japan Russia etc..I am not drinking this cool-aid.@

but the impurities in fossil fuels are destroying our environment. We used to believe that dilution was the solution to pollution
2. A NEW Gallup Poll says over 70%of Americans want more WIND and SOLAR ENERGY. 3. Hansen and Kharecha and everyone should watch the presentations at the Symposium on the Medical
and Ecological Consequences of Fukushima in which the amount of cancers caused by radiation in our food
and in our environment from nuclear meltdowns and nuclear power plants was discussed. The total amounts of deaths birth defects miscarriages heart attacks cancers etc. due to nuclear radiation is in the millions upon millions;
and Wind aren't preferable to Nuclear but I*am*saying Nuclear is by far preferable to filthy coal and oil.@
and the environment would be cleaner too...nice warm happy sigh. Dare to DREAM! One day to be solar is the way to go!
To the (solar and wind are so much better!!!people what you need to take a look at is energy density.
Yes you could replace every watt of energy production with wind and solar...but you would destroy cover
You can replace hundreds of wind turbines and square miles of solar farms with one bnuclear power plant.
The small amount of radiation claimed to be safe by authorities added to our increasingly fragile environment will cause serious harm to the health of human beings and other living organisms all over the world.
Man-made nuclear radiation is wreaking havoc on human genetics human health and our environment. NEW Gallup Poll:
Americans Want More Energy From Wind Solar Gasno fewer than two in three Americans want the U s. to put more emphasis on producing domestic energy using solar power (76%)wind (71%)and natural gas (65%.
and extremely conservative dosage limits set in place to protect the safety of people who work in environments where radiation exposure is commonplace.
88%Wind: 87%Natural gas: 89%Oil: 67%Nuclear power: 65%Coal: 56%In other words generally speaking Americans want to become energy independent through ALL THE resources at our disposal. http://www. gallup. com/file/poll/161525/Energy sources 130327. pdfthis is absolutely true
Some benefits to health and the environment are just a better trade off. We need to do a lot more development towards solar power.
And these benefits also apply to wind and hydroelectric power as well. Solar wind and hydroelectric systems do not pollute
but in one other story that was discussing future concepts of skyscrapers one was harnessing noise pollution to create energy another was using volcanos
I believe there are several more means that exist to create energy with relatively fewer adverse effects on the environment f
After Hurricane Sandy shoved water into Con Edison's 14th street substation in October causing electricity to arc between capacitors about a quarter million customers were left in the dark.

Such infrastructure would be more resilient to both storms and terrorist attacks which the National Research Council warned in November could cripple entire regions of the country for months.

Florida Power and Light whose customers experienced multiple hurricanes in the early 2000s was among the first to do so.

or above a critical threshold for ecological damage according to a study published in the journal Atmospheric Chemistry
The environmental scientists experts in air quality atmospheric chemistry and ecology have been studying the fate of nitrogen-based compounds that are blown into natural areas from power plants automobile exhaust and--increasingly--industrial agriculture.
Nitrogen that finds its way into natural ecosystems can disrupt the cycling of nutrients in soil promote algal overgrowth
and lower the ph of water in aquatic environments and ultimately decrease the number of species that can survive.
The vast majority 85 percent of nitrogen deposition originates with human activities explains principal investigator Daniel J. Jacob Vasco Mccoy Family Professor of Atmospheric Chemistry and Environmental Engineering at the Harvard
The team of scientists--comprising researchers from Harvard SEAS the National park service the USDA Forest Service the U s. Environmental protection agency
and the University of California Irvine--presents evidence that unchecked increases in nitrogen deposition are already threatening the ecology of federally protected natural areas.
In many previous studies environmental scientists have identified the nitrogen levels that would be ecologically harmful in various settings.
In Eastern temperate forests like those in Great smoky mountains national park the most sensitive elements of the ecosystem are the hardwood trees
She now directs the Climate and Urban Systems Partnership at the Franklin Institute. Jacob Ellis and their collaborators predict that NOX emissions from the United states will decrease significantly by 2050 (globally those decreases may be offset to some extent by increases in industrialization overseas.
When you try to write regulations to protect ecosystems however the damage is much harder to quantify says Jacob.
Actual levels of future nitrogen deposition will depend on a complex interplay of economic legal and environmental factors.

and ecosystem researchever wonder what plants do when you're not around? How about an entire forest or grassland?
Not even the most dedicated plant researcher can be continuously present to track environmental effects on plant behavior
This system greatly improves the utility of time-lapse photography by capturing interactions between the environment and a plant population in a single sequence.
Environmental responses can be seen across a large population with the additional advantage of examining individual responses within the same population using one time-lapse sequence.
The rapid greening response of the grassland to rainfall is seen easily as well as the response of an individual cholla cactus as its branches become erect due to the rainfall.
As Steven emphasizes The technique has amazing potential to study the importance of the environment on plant phenology and behavior.
Depending on the researcher's needs the time-lapse sequence can be scaled from hours (e g. flash floods) to years (e g. post-fire recovery.
This new technique will be a powerful tool to allow researchers to simultaneously examine environmental influence over time across a population as well as at a high-resolution on a single plant and to do so with a minimum of manpower.
Additionally it will be useful in a number of other disciplines including geology archaeology biodiversity glaciology and rangeland ecosystem research.

#Spring rains bring life to Midwest granaries but foster Gulf of mexico Dead Zonenew ORLEANS April 9 2013#The most serious ongoing water pollution problem in the Gulf of mexico originates not from oil rigs as many people believe but rainstorms and fields of corn and soybeans a thousand
miles away in the Midwest. An expert on that problem#the infamous Gulf of mexico#oedead Zone##today called for greater awareness of the connections between rainfall and agriculture in the Midwest and the increasingly severe water quality problems in the gulf.
Keynoting a symposium at the 245th National Meeting & Exposition of the American Chemical Society the world s largest scientific society Nancy N. Rabalais Ph d. emphasized that oil spills like the 2010 Deepwater Horizon disaster claim a terrible toll.
Sometimes however they overshadow the underlying water pollution problem that has been growing more and more severe for almost 40 years.#
#oethe Dead Zone is a vast expanse of water sometimes as large as the state of Massachusetts that has so little oxygen that fish shellfish
Climate change surging population growth and other factors stand to make matters worse. I hope this symposium helps engage scientists in seeking solutions that help sustain Earth and its people.#
Oil spills and other local pollution compound those negative effects on marine life Rabalais noted By day 77 of the Deepwater horizon disaster for instance the oil slick had covered about one-third of the Dead Zone making it even more inhospitable.
To address the major challenges in managing the growing amounts of animal and human waste water pollution; protecting water resources and restoring an economically vital coastline we will need to invest in the characterization of our water microbiological communities and shift the pollution science paradigm toward an understanding of risk and resilience under global change.

#Environmental policies matter for growing megacitiesa new study shows clean-air regulations have reduced dramatically acid rain in the United states Europe Japan
and sulfate in rain--components contributing to acid rain said Suresh Rao Lee A. Reith Distinguished Professor of Civil engineering and Agronomy at Purdue University.
The effects of acid rain can propagate through aquatic ecosystems such as lakes rivers and wetlands and terrestrial ecosystems including forests
and soils negatively impacting ecological health. Researchers have used now publicly accessible data collected weekly or monthly at numerous monitoring sites during the period from 1980-2010 to track wet deposition of nitrate and sulfate near several U s. and East Asian cities.
The pollutants products of fossil fuel combustion are emitted by cars trucks and buses. Pollutants rise up into the atmosphere
or snow or as dry deposition between rain events. Fast-growing cities in East asia that lack regulations or enforcement show a dramatic rise in acid rain according to the new study completed by Purdue researchers Our analysis of wet deposition (acid rain) data provides compelling evidence
and enforcement of environmental regulations are profoundly important Rao said. The findings of the study are detailed in a research paper published in the journal Atmospheric Environment.
The article is accessible online and will appear in the May issue. It was authored co by civil engineering postdoctoral researchers Jeryang Park and Heather Gall and by Rao and Dev Niyogi Indiana state climatologist and an associate professor in the Purdue Department of Agronomy and the Department of Earth
Severe problems with air pollution also are evident in particulate matter (PM) concentrations contributing to smog.
The impact cities can have on the environment we find is a function of growing population
In essence we've solved the acid rain problem through good environmental regulations and wide adoption of mitigation technologies.
even though rainfall patterns vary widely from one city to another the annual average rate of nitrate
Because rainfall patterns vary so much from one location to another you would think wet deposition also would vary.
When mitigation strategies are adapted widely it is possible for cost-effective engineering solutions to protect the environment
Given certain emissions and rainfall patterns we can now project how wet deposition rates would increase initially
Additionally the model can be used to examine wet deposition rates under climate-change scenarios The study findings also have implications for variations in wet deposition rates under shifting weather resulting from climate-change scenarios as well as rapid urbanization
Although annual wet deposition patterns are influenced by variability in rainfall amounts both within a year
For example even though Xi'an China is predicted to become drier in the future due to climate changes the data
and modeling analysis revealed that long-term climate oscillations--like El nino and La Nina cycles--could induce dramatic increases in the concentration of pollutants in rainfall ultimately leading to increased wet deposition of pollutants.
This implies that when regulations are implemented inadequately climate change could result in much larger impacts on the environment said Park the article's lead author.
Future work will shift focus to Sub-saharan africa where major growth is anticipated later in the century.
