Non-GMO Corn Day Celebration
Launching date of Non-GMO Tortilla Campaign
Dear Allies, Supporters and Friends,
Biosafety Alliance ask Non-GMO advocate individuals and organizations to support the Latino community by participating and attending the “Non-GMO Corn Day Celebration” on September 29th at 24th Street at Mission BART station in San Francisco from 11:00 AM -3:00 PM.
Non-GMO Corn Day Celebration is to bring awareness about the importance to protect native corn from biotech genetic contamination. We are in solidarity with the grassroots movement in Mexico: to protect Mexico as the CENTER OF ORIGIN of native corn therefor not allowing companies like Monsanto to plant GMO corn in Mexico because it will inevitably contaminate native corn through cross pollination.
Corn has been planted by the indigenous people through the Americas for 10,000 years. Corn is their staple food, good for the body and spirit. It is also an intricate part of their cultural and Identity. Corn is a gift to humanity not a patent for profit. We must keep our seeds pure and untainted for future generations.
The event will also be the beginning of a Latino campaign demanding the following:
·Demand to Latin Politicians to advocate for Non-GMO corn to be available in food markets in communities of color.
·Demand GMO Foods, in particular GMO Tortillas, to be labeled.
·Demand democracy in our food system, we have the right to know what is in the food we buy and feed our families.
We intend to gather during next 6 months 1000 000 signatures in support of GMO Tortilla labeling in California that we will bring to Sacramento in a massive mobilization, we need your help!
Come celebrate the food movement as we enjoy Non-GMO food including organic purple tortillas, music, art, speakers, and ceremony. There will be music, poetry and information. This is a family event and everyone is welcomed. The event will also take place in Los Angeles, Stockton, East Palo Alto and San Luis Obispo.
Facebook event in San Francisco: Join us!

Mary Robinson: climate change is a ‘serious issue of human rights’

Mary Robinson, former president of Ireland, speaks to RTCC about climate justice, the UN, and why climate sceptics make her angry
By Sophie Yeo
Climate justice is a phrase which eludes a neat definition.
Morally laden and politically controversial, it is used interchangeably to discuss the law, politics and ethics of climate change. Even the most seasoned negotiators may find themselves promoting one of its many meanings over another.
For Mary Robinson, these various meanings are not disconnected concepts, but a jigsaw of related ideas that together create a comprehensive picture of how best to tackle one of the world’s greatest problems: “When we’re talking about climate change, the issue of justice starts with injustice,” she says.
A barrister, a politician, and a top official in the UN, Robinson, now 69, remains best known as the first female president of Ireland – a largely ceremonial role she occupied between 1990 and 1997 through which she strove to influence through the “moral authority” it bestowed on her.
She admits that moral leadership continues to fascinate her, and is something she continues to exercise since became a member of the Elders in 2007, a group of global leaders, brought together by Nelson Mandela, who work together to provide guidance on peace making and human rights.
She was led to the climate debate, she says, not as a scientist or even as an environmentalist, but through her campaign work on human rights.
“I was very struck by the fact that the impacts of climate change are undermining a whole range of human rights: rights to food, safe water and health and education,” she says.
“But it is also displacing people, which is very likely to cause not just human distress but potentially conflict. So for me it’s a very, very serious issue of human rights.”
Throughout her career, Robinson taken many approaches to the fight against injustice. Not satisfied to rely on the influence she wields through the UN, she has also sought to encourage leadership at a grassroots level, and established the Mary Robinson Foundation – Climate Justice, through which she promotes action on a more direct scale than is possible through her other roles.
“There’s good grassroots leadership if only we’d listen to it,” she says. “They are the resilient experts on how to cope with the increasing negative impacts of climate change.
“I’m very struck by the resilience of local communities and the local knowledge that is used, but they don’t have insurance, and the unpredictability is really hurting.”
As a lawyer, trained in her teens and early twenties at Trinity College Dublin and Harvard Law School, she is now advocating for a strong legal framework through which climate policy can be enforced.
The Mary Robinson Foundation has joined forces with the World Resources Institute to put together a declaration on climate change to be published during the week of the United National General Assembly, highlighting issues that need to be addressed to bring about climate justice.
One aspect of the declaration that she says she is particularly pleased about is that it highlights the importance of rule of law.
“There is a need for a strong legal framework to ensure transparency, credibility and effective enforcement of climate and related policy. We firmly believe that legal systems need to protect the most vulnerable,” she says.
As former UN High Commissioner for Human Rights, Robinson has learnt from experience how to work the system at an international level, and is hopeful that this declaration, put together by former heads of state, climate experts and also representatives of social communities and academia, will prevent the issue of climate justice being drowned out by other concerns.
Equity
She is passionate about the overtly political issue of equity, which is becoming ever more prominent at high level negotiations.
Discussions of equity, or the issue of who should foot the bill for climate change, are particularly prone to slipping into emotive debate, with the wrangling over how the developed countries can best make amends for their historical responsibility for climate change having held up concrete action for years.
But enshrining principles of justice into mutually satisfying financial arrangements is always going to be a troublesome task, and it doesn’t help that the dryly worded UNFCCC definition – “common but differentiated responsibilities and and respective capabilities” – is frustratingly vague, leaving open for interpretation some of the most controversial decisions about what ‘justice’ actually means.
The difficulties embedded in this definition makes talking about the equity issue problematic, says Robinson.
Developed countries, for instance, who are looking to avoid donating vast sums to other countries, can promote the ‘capability’ aspect of equity over their own ‘responsibility’, suggesting that any country with the ability to do so should take the flak for reducing their own emissions regardless of their historical responsibility for the problem.
Developing economies such as China, on the other hand, will focus on their right to use fossil fuels to develop in the present as the UK and the US have done in the past, and that it is therefore up to these countries to enable them to do so.
Meanwhile, in places such as Gambia, where emissions remain low but climate impacts are already severe, the endless quarrelling over equity can seem little more than a frustrating failure to act.
A practical approach
Despite her concern for the damage already being done to the most vulnerable countries, Robinson is unwilling to let the emotional nature of the problem interfere with her pursuit of the most effective solution. Indeed, she says that her response to climate change in general stems more from “emotional intelligence” than emotion itself.
In the clipped tones of a veteran politician, she says: “Now the emerging countries are responsible for a greater part of the emissions, and developing countries generally emit more than the developed world, so we’ve got a new kind of responsibility, and that’s why I think you can get locked in to the historic responsibility in an unrealistic way.”
But, she adds: “There has to be an acknowledgement of the historic responsibility before people fully appreciate it.”
“It has to be acknowledged, and it has to be addressed in particular by greater commitments by those countries that benefitted in their economic development from fossil fuels – that’s the reality.
“Therefore they have to commit to more serious reductions of emissions because they’re in a position to move more rapidly towards renewable energy.”
The only time when her pragmatic breed of stoicism slips is when the subject of climate deniers arises. It is “hard to be patient” with sceptics, she says, because of the corrupt way in which much of it is funded by fossil fuel lobbies.
“That makes me angry because they’re playing with the future of people in the world, and it’s an injustice that it’s hurting the poorest already and will hurt them most,” she says.
“So I do feel quite angry – not just frustrated, quite angry – at lobbying against the reality. Climate justice keeps faith with science and is based on acknowledging the importance of the true science on this.”
Human rights
She left the UN as High Commissioner for Human Rights in 2002, but has since taken up the role of Special Envoy to the Great Lakes region of Africa, which encompasses the Democratic Republic of Congo, Rwanda and Uganda – countries where conflict and climate stresses are putting human rights on the top of the agenda – on the particular request of Ban Ki-moon
In every country in the Great Lakes, she says, climate shocks are undermining food security, while the population just keeps on rising. But, she adds, the thought processes surrounding the two issues are still not as connected as they could be.
“Governments have agreed in the context of the Human Rights Council that climate change is eroding and undermining the protection of human rights, but this has not been joined up to thinking in the context of the environmental and energy ministers who go to the climate conference,” she says.
“I believe we have to join that up more. That’s where climate justice is helpful, because it’s a link between climate change, development and human rights. We will be working strongly with the Human Rights Council over the coming year to make sure that voice is heard and that we have joined up thinking at government level.”
United Nations
Is it possible to spend so many years in the UN and not be disillusioned by the system, which has so far failed to put a satisfying proposal on the table on how to cut global carbon emissions? “It’s always frustrating,” she says, “and yet the UN has the value that all countries are involved in it, so I have to be patient with a very bureaucratic and sometimes unwieldy system and try to get results.”
Plus, she adds, despite her emphasis on the virtues of grassroots leadership, she still firmly believes that the UN is key to getting the world back on track.
“We can come together under the UN system if we are intelligent about what we want to do, that we want a fair robust climate agreement,” she says, “because we must have an agreement which commits countries to bring us below the 2C warming, which will mean a safe world for generations to come.
“That’s a huge responsibility and we cannot avoid it. We do need the climate agreement to reach that.”
And the 21st Conference of Parties in Paris in 2015 – an event which many look towards as the final deadline for putting a framework in place to reduce global carbon emissions – is an unparalleled opportunity to should this responsibility, she says.
“It’s very rare to have a year like 2015, where the world faces two huge complementary agendas,” she says, referring to the paradigm-shifting replacement of the Millennium Development Goals with a set of Sustainable Development Goals, along with the global commitment to come up with a legally binding agreement that will keep the world below 2C of warming, the temperature considered ‘safe’ by scientists.
“I borrow the words of Desmond Tutu: I’m not an optimist, I’m a prisoner of hope,” she says.
“I’m a grandmother. I think a lot about my four grandchildren. They’ll be in their forties by 2050 and they’ll share the world with nine billion others. I want it to be a safer world than we’re predicting at the moment. I want it to be a world where they can say at least when they got round to it in 2015 they took their responsibilities.
“I don’t want them to say how could they have been so selfish and so stupid that they didn’t see the impacts on us and our children and grandchildren in the future? That’s a preoccupation of mine.
“If by the end of 2015 we have really accepted and understood our responsibilities then I think our grandchildren and their grandchildren will acknowledge that we helped them.”

Women living near pesticide-treated fields have smaller babies
Women in Northern California farm towns gave birth to smaller babies if they lived within three miles of strawberry fields and other crops treated with the pesticide methyl bromide, according to researchers. The soil fumigant, which is injected into the soil before planting, can volatize into the air, exposing nearby neighborhoods. Use of methyl bromide has been declining over the past decade under an international treaty that phases out chemicals that deplete the Earth’s protective ozone layer. Strawberries and a few other crops are exempt under the ban because they are deemed “critical uses.”

Women in Northern California farm towns gave birth to smaller babies if they lived within three miles of strawberry fields and other crops treated with the pesticide methyl bromide, according to researchers.
“There’s been very little research on residential exposure to methyl bromide. Our study is the first to look at methyl bromide and birth outcomes,” said Kim Harley, study author and associate director of the Center for Environmental Research and Children’s Health at the University of California, Berkeley.
The soil fumigant, which is injected into the soil before planting, can volatize into the air, exposing nearby neighborhoods.
Use of methyl bromide has been declining over the past decade under an international treaty that phases out chemicals that deplete the Earth’s protective ozone layer. Strawberries and a few other crops are exempt under the ban because they are deemed “critical uses.”
The researchers studied babies born to 442 pregnant women, mostly Latinas from Mexico, living in the Salinas Valley in 1999 and 2000, when methyl bromide was widely used. Its use near each woman’s home was based on data from the state’s Pesticide Use Reporting system.
Methyl bromide, which is injected into the soil of strawberry fields and other crops before planting, can volatize into the air, exposing nearby neighborhoods.Use of the pesticide within three miles of the home during the second trimester of pregnancy was associated with an average birth weight about 4 ounces less than babies from areas with no methyl bromide use.
That 4-ounce difference is about half the birth weight decrease linked to smoking during pregnancy, the researchers said.
The significance of the slightly smaller babies when it comes to their health is unknown because they are within normal ranges. Only 4 percent of the babies were born at what is considered a low birth weight, less than 5.5 pounds. Low birth weight babies may be at risk for developmental delays and learning problems.
“This data would be more meaningful if it demonstrated that exposure led to abnormality,” wrote Giffe Johnson, a toxicologist at the University of Southern Florida who studies pesticide levels in agricultural workers.
Harley said that while the clinical significance of the findings remains unclear, “for a baby on the low end of normal birth weight, 4 ounces could make a big difference.”
Harley also noted that while this group of agricultural workers, and Mexican immigrants in general, tend to have healthy birth weight babies, “across the board, we saw a shift toward slightly lighter babies.”
One major limitation is that no one knows how much methyl bromide the women were actually exposed to. Their exposures were estimated based on their addresses, with no actual measurements.
“A woman could work 12-hour shifts 40 miles from home or spend little time outdoors near her own home. It’s impossible to say whether these estimates represent an accurate picture of exposure,” said Myles Cockburn, an epidemiologist at the University of Southern California who studies pesticides.
One major limitation of the research is that the scientists do not know how much methyl bromide the women were actually exposed to.About 41 percent of the women did some field work while pregnant, although few worked in fields that had been treated with methyl bromide.
The link to birth weight was reported only for exposures in the second trimester, not for the first or third trimesters. “The second and third trimesters are major periods for fetal growth. The second trimester may be a critical period for exposure to the pesticide,” Harley said.
Previously, animal studies have suggested that methyl bromide may harm fetal development.
While strawberry growers have been trying to replace methyl bromide for several years, no suitable alternatives have been found to work on a large scale.
Methyl bromide use has been cut nearly in half in California since 2002, but growers there still used almost 4 million pounds in 2011, according to the California Department of Pesticide Regulation.
Despite the decline in usage, “the findings remain very relevant for the farm worker population, especially those living in agricultural areas where strawberries are grown,” Harley said.
The methyl bromide study is part of a 14-year, ongoing project by the scientists to investigate potential health effects of environmental exposures on children born in the Salinas Valley, one of the nation's most productive agricultural regions.
The California Strawberry Commission and CropLife America, a trade group representing pesticide manufacturers, were unavailable for comment on the new study.

Climate Change and Health in California
I dropped in on a presentation by Linda Rudolph, M.D., M.P.H. at the monthly BAAQMD advisory council meeting. Dr. Rudolph is from Climate Health Connect and the Public Health Institute. While Monsatan & unsustainable ag systems are a major threat to global food security, climate change is a clear and present danger to all life systems on earth, including those that feed us. We need immediate and drastic changes to all sectors in every country, and I implore whoever reads this pathetic excuse for a blog to make time to help change the tide. It's not radical - It's called survival instinct. Most species protect their young. The corporate polluters are powerful, but together, we average citizens can be a force of change. We need all hands on deck! - Please contact your local 350.org chapter and get involved. - Betty -
Here is what I learned yesterday:
- Climate change is the greatest public health challenge of the 21st Century.
- We can create climate for health: Reducing, Ready, Resilient
- There are many win-win opportunities to simultaneously improve health and address climate change
- We need faster and more aggressive action to avert catastrophic impacts on our children and grandchildren
----------------------------------------------------------------------------
Climate Change is Happening Now
- Warming is unequivocal; most of the warming of the past 50 years is very likely (90%) due to increases in greenhouse gases.
- Warming, plus heat waves, wind patterns, drought, & more
- Physical and biological systems on all continents and in most oceans are already affected by recent climate change.
- Greenhouse gases at unprecedented levels, forcing the climate to change.
- Already committed to more warming (next few decades); choices about emissions effect the longer term more and more. (IPCC2007)
------------------------------------------------------------------------------
"Climate change is the biggest global health threat of the 21st century... The impacts will be felt all around the world - and not just in some distant future but in our lifetimes and those of our children." -- The Lancet
----------------------------------------------------------
- More extreme temps means heat stress and cardiovascular failure
- Sea level rise and saline intrusion will bring forced migrations (mental health impact... anxiety, despair, depression, PTSD)
- Stronger hurricanes & storm surges = fatalities and injuries, mental health issues
- Increased ozone concentrations & diminished air quality = increased asthma, respiratory disease
- Increased pollen & natural air pollutants = increased allergens. (pollen production and concentrations to TRIPLE by 2040)
- More dust = more Valley Fever in California
- Increased precipitation and flooding in some areas = more water, food, and vector-born diseases like malaria, dengue fever, encephalitis, cholera, diarrhea, salmonella, shigella, camphylobacter cryptosporidoiosis.
- Increased droughts and water scarcity, water contamination = threats to water and food security, migration, mental health issues, civil conflict. (Locally, California is drying. We are already seeing less snowpack and earlier snowmelt in the Sierras, which is a huge threat to the state's agriculture sector and our overall economy.)
- Ocean acidification = food insecurity, collapse of whole ecosystems on land as well.
- More frequent wildfires.
- New range of disease vectors.
- Increase in harmful algal blooms = hypoxic dead zones
---------------------------------------------------------------------------------
THREATS TO SURVIVAL
Climate change threatens the systems on which humans depend for survival.
- Air
- Water
- Food
- Shelter
- Peace/Security/Social Stability
----------------------------------------------------------------------------------
VULNERABILITY AND RESILIENCE
Vulnerability:
- Susceptibility to harm
- Exposure to, sensitivity to, ability to cope with or adapt

---------------------------------------------------------------------------------------
THE CLIMATE PENALTY
- Warmer temps will increase frequency of days with unhealthy levels of ground-level ozone.
- May push O3 concentrations beyond current year-to-year variability; may lengthen the O3 season.
- Possible increase in biogenic emissions of O3 precursors, (eg VOCs); possible increases in lightening NOx production may also be a factor in future O3 changes.
- Bay Area: The sensitivity of ozone to increases in temperature is relatively large compared to other regions in the state, suggesting the Bay Area may be particularly sensitive to climate change (Steiner, Tonse et al. 2006).
-------------------------------------------------------------------------------------
WILDFIRE RISK
- Earlier snowmelt, higher temperatures, longer dry periods, longer fire season.
- Changes in vegetation (more poison oak/ivy)
- Ignition potential from lightening
- Human activities biggest factor in ignition risk.
- Increases in the number of large fires statewide, ranging from 58% to 128% by 2085
- Estimated burned area will increase by 57% to 169%

Dr. Linda Rudolph, M.D., M.P.H.
Here is what I learned yesterday:
- Climate change is the greatest public health challenge of the 21st Century.
- We can create climate for health: Reducing, Ready, Resilient
- There are many win-win opportunities to simultaneously improve health and address climate change
- We need faster and more aggressive action to avert catastrophic impacts on our children and grandchildren
----------------------------------------------------------------------------
Climate Change is Happening Now
- Warming is unequivocal; most of the warming of the past 50 years is very likely (90%) due to increases in greenhouse gases.
- Warming, plus heat waves, wind patterns, drought, & more
- Physical and biological systems on all continents and in most oceans are already affected by recent climate change.
- Greenhouse gases at unprecedented levels, forcing the climate to change.
- Already committed to more warming (next few decades); choices about emissions effect the longer term more and more. (IPCC2007)
------------------------------------------------------------------------------
"Climate change is the biggest global health threat of the 21st century... The impacts will be felt all around the world - and not just in some distant future but in our lifetimes and those of our children." -- The Lancet
----------------------------------------------------------
- More extreme temps means heat stress and cardiovascular failure
- Sea level rise and saline intrusion will bring forced migrations (mental health impact... anxiety, despair, depression, PTSD)
- Stronger hurricanes & storm surges = fatalities and injuries, mental health issues
- Increased ozone concentrations & diminished air quality = increased asthma, respiratory disease
- Increased pollen & natural air pollutants = increased allergens. (pollen production and concentrations to TRIPLE by 2040)
- More dust = more Valley Fever in California
- Increased precipitation and flooding in some areas = more water, food, and vector-born diseases like malaria, dengue fever, encephalitis, cholera, diarrhea, salmonella, shigella, camphylobacter cryptosporidoiosis.
- Increased droughts and water scarcity, water contamination = threats to water and food security, migration, mental health issues, civil conflict. (Locally, California is drying. We are already seeing less snowpack and earlier snowmelt in the Sierras, which is a huge threat to the state's agriculture sector and our overall economy.)
- Ocean acidification = food insecurity, collapse of whole ecosystems on land as well.
- More frequent wildfires.
- New range of disease vectors.
- Increase in harmful algal blooms = hypoxic dead zones

Widely Used Herbicide Commonly Found in Rain and Streams in the Mississippi River Basin

| Glyphosate, also known by its tradename Roundup, is commonly found in rain and rivers in agricultural areas in the Mississippi River watershed, according to two new USGS studies released this month. Glyphosate is used in almost all agricultural and urban areas of the United States. The greatest glyphosate use is in the Mississippi River basin, where most applications are for weed control on genetically-modified corn, soybeans and cotton. Overall, agricultural use of glyphosate has increased from less than 11,000 tons in 1992 to more than 88,000 tons in 2007. "Though glyphosate is the mostly widely used herbicide in the world, we know very little about its long term effects to the environment," says Paul Capel, USGS chemist and an author on this study. "This study is one of the first to document the consistent occurrence of this chemical in streams, rain and air throughout the growing season. This is crucial information for understanding where management efforts for this chemical would best be focused." In these studies, Glyphosate was frequently detected in surface waters, rain and air in areas where it is heavily used in the basin. The consistent occurrence of glyphosate in streams and air indicates its transport from its point of use into the broader environment. Additionally, glyphosate persists in streams throughout the growing season in Iowa and Mississippi, but is generally not observed during other times of the year. The degradation product of glyphosate, aminomethylphosphonic acid (AMPA), which has a longer environmental lifetime, was also frequently detected in streams and rain. Detailed results of this glyphosate research are available in "Occurrence and fate of the herbicide glyphosate and its degradate aminomethylphosphonic acid in the atmosphere," published in volume 30 of Environmental Toxicology and Chemistry and in "Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins," published online in Pest Management Science. Copies of the reports are available from the journals or from Paul Capel (capel@usgs.gov). Research on the transport of glyphosate was conducted as part of the USGS National Water-Quality Assessment (NAWQA) program. The NAWQA program provides an understanding of water-quality conditions, whether conditions are getting better or worse over time, and how natural features and human activities affect those conditions. Additional information on the NAWQA program can be found online. |

The past 10 years were the warmest since the start of modern measurements
The past 10 years were the warmest since the start of modern measurements 160 years ago and it was also a decade of unprecedented extremes in the climate according to a report by the World Meteorological Organisation (WMO).
Heatwaves in Europe and Russia, hurricane Katrina in the United States, tropical cyclones in South East Asia, droughts in the Amazon, Australia and East Africa and floods in Pakistan were all features of the last decade indicating a shift in the climate, the WMO said.
Both the northern and southern hemispheres experienced the warmest temperatures for both land and sea, puncturing the myth that global warming has ended. At the same time, there was a rapid melting of Arctic sea ice and an acceleration in the loss of ice from the massive ice sheets of Greenland and the Antarctic.
As a result of this widespread melting and the thermal expansion of sea water, global mean sea levels rose about 3 millimetres (mm) per year, about double the observed 20th century trend of 1.6 mm per year. Global sea level averaged over the decade was about 20 cm higher than that of 1880, said the report.
"A decade is the minimum possible timeframe for meaningful assessments of climate change," said Michel Jarraud, the WMO's secretary general.
"WMO's report shows that global warming was significant from 1971 to 2010 and that the decadal rate of increase between 1991-2000 and 2001-2010 was unprecedented. Rising concentrations of heat-trapping greenhouse gases are changing our climate, with far reaching implications for our environment and our oceans, which are absorbing both carbon dioxide and heat," Mr Jarraud said.
The WMO report said atmospheric concentrations of greenhouse gases continued to rise. Global-average concentrations of carbon dioxide in the atmosphere rose to 389 parts per million in 2010, an increase of 39 per cent since the start of the industrial era in 1750.

Wild and domestic cattle will drastically shed weight as the climate warms
Cattle weight loss means slimmer profits in a warmer world
LONDON – Cherish your hamburger today, America. Tomorrow it could be skimpier.
The nation's cattle herds will shrink – not in number, but in weight and yield – as the climate warms, according to new research that delivers an ominous warning for farmers.
An extensive study of bison – those great wild cattle that evolved to graze the prairies of North America – has confirmed that animals from warmer, drier grasslands weigh considerably less on average than those from cool, wet ranges.
The difference in mean annual temperature between the two ranges was 11° Celsius, and the two sets of values told an ominous story of change in a warming world – not just for wild bison, but also for domestic cattle.
The world is almost certain to warm by more than 2°C on average in this century, and the rise could be as great at 4°C.

As temperatures rise, precipitation is likely to fall, with consequences for plant growth. If the same reduction in weight gain applies to beef cattle as to bison, as researchers suspect, the finding is "a pretty clear indication" of bad news for food security and for the grazers.
There are around 500,000 bison in the United States – the species was all but extinguished during the 19th century – and more than 90 million cattle. Craine calculates that each 1°C rise in average temperatures could cost farmers $1 billion in profits, either through direct reduction in weight gains or in the costs of additional supplementary feeds.
The research is in line with other findings this year. Evidence from 55 million years ago – when the world warmed by 6°C – unearthed during the National Science Foundation's Bighorn Basin Coring Project in Wyoming indicated that animal size tended to dwindle with rising temperatures, almost certainly in response to changes in nutritional value.
The implication that mammals could dwarf and humans shrink towards hobbit-like stature under a changing climate was tragically confirmed by a study of body heights among children in north-east Brazil.
In response to near-starvation conditions, children brought up on a diet of rats, snakes and cacti reached an average adult size of only 1.35 meters, or 4.5 feet.

A study of bison in the U.S. predicts that wild and domestic cattle will drastically shed weight as the climate warms – compromising food security and stripping billions from farm profits
By Tim RadfordClimate News Network
The nation's cattle herds will shrink – not in number, but in weight and yield – as the climate warms, according to new research that delivers an ominous warning for farmers.
Animals from warmer, drier grasslands weigh considerably less on average than those from cool, wet ranges.
600 pounds lighter
Kansas State University researcher Joseph Craine reports in the Public Library of Science journal PloS One that he analyzed weight, age and sex data from 290,000 bison in 22 herds throughout the United States.
It all lines up to suggest that climate change will cause grasses to have less protein, and cause grazers to gain less weight in future. - Joseph Craine, Kansas State Univ.
He found that the average seven-year-old male bison in South Dakota weighed 856 kilograms (around 1,900 pounds), while counterparts in Oklahoma clocked in at 596 kg (1,300 lbs).The difference in mean annual temperature between the two ranges was 11° Celsius, and the two sets of values told an ominous story of change in a warming world – not just for wild bison, but also for domestic cattle.
The world is almost certain to warm by more than 2°C on average in this century, and the rise could be as great at 4°C.
Less protein
"We know that temperatures are going to go up," Craine said. "We also know that warmer grasslands have grasses with less protein, and we now know that warmer grasslands have smaller grazers. It all lines up to suggest that climate change will cause grasses to have less protein, and cause grazers to gain less weight in future."As temperatures rise, precipitation is likely to fall, with consequences for plant growth. If the same reduction in weight gain applies to beef cattle as to bison, as researchers suspect, the finding is "a pretty clear indication" of bad news for food security and for the grazers.

Evidence from 55 million years ago – when the world warmed by 6°C – unearthed during the National Science Foundation's Bighorn Basin Coring Project in Wyoming indicated that animal size tended to dwindle with rising temperatures, almost certainly in response to changes in nutritional value.
The implication that mammals could dwarf and humans shrink towards hobbit-like stature under a changing climate was tragically confirmed by a study of body heights among children in north-east Brazil.
In response to near-starvation conditions, children brought up on a diet of rats, snakes and cacti reached an average adult size of only 1.35 meters, or 4.5 feet.
