10% OF US KIDS & 40% OF OBESE US KIDS
HAVE FATTY LIVER DISEASE
Dioxin in smoke, deposited on range and farmland resulting in human ingestion and accumulation in fatty tissues. 80% of dioxin exposure is from beef and dairy
Pollutants that are volatile, that change to a gaseous form at natural temperatures, move from soil to air and then deposit back into soil or water when they meet cold air. Grasshopper effect Bioconcentration in fish Bioconcentration factors for fish have been documented
to occur from 3,000 to 247,000 times ambient levels
PAH also in wildfire smoke adhered to very fine particulates. In addition to consumption of contaminated food , Inhalation is a signifcant exposure route, can cause lung cancer. PAHis very persistent. levels are used by paleontologists studying prehistoric fires.
Runoff from burned areas, has higher levels of PAH than urban runoff.
Elevated mercury in cord blood tripled risk of developmental delay at 1 year
Estimations of average fish consumption for purposes of regulating water quality have become political issues between industry, government, environmentalists, and native american groups. WA using thimbleful at day, OR uses estimate that is 3 times higher,
Adults in columbia river intertribal fish commission's member tribes who eat fish frequently (48 meals per month) over a period of 70 years may have cancer risks that are up to 50 times higher than those in the general public who consume fish about once a month.
Evaporation of surface water concentrates and existing contaminants
Flow reverses, surface water moves into groundwater
Increased pumping for irrigation drops water table
Arsenic in aquifer bound to other minerals converts to arsenate and arsenite (more mobile and 500x more toxic )
Unused fertililzer not taken up by drought stunted plants will sink down into groundwater with next rain and also run into rivers and lakes, increasing HABs
Thyroid cancer increased with water half the EPA standard, nitrates plus atrazine non hodgkins lymphoma
Dry lake beds which can contain high levels of minerals left behind when the water evaporated. Owens Lake emits about 300,000 tons of PM-10 per year: 30 tons of this is arsenic and 9 tons is cadmium.Aerosols sampled from Owens dust storms commonly contains significant amounts of arsenic concentrated in the <10 micron fraction. levels can be as high as 400 ng/m3
About 25% of airborne arsenic in SE US comes in dust from Africa
Combination of nutrient load from ag runoff and warm water causing increased fresh water algae blooms.
2 problems:
1) microcystin The extensive HAB on Lake Erie in 2011
microcystin concentrations exceeding 1000 ug/L limit is 1ug/l
2) increased dissolved organic carbon resulting in trihalomethanes, carcinogenic byproducts of chlorine disinfection
prenatal exposure to brominated THM increase the risk of congenital heart and musculoskeletal anomalies.
Use of choloramine- not as effective LA Naegleria in public water systems, In DC lead leached from pipes
HABs in ocean are also the result of ag drainage of nutrients and warmer water.
Toxins concentrate in clams, mussels, oysters and cause human illness
Poisoning events are increasing, closures by PHDs are becoming more frequent
TERATOGENIC, DECREASED BIRTH WEIGHTS. PLACENTA CONCENTRATES, found levels 6x higher in cord blood than maternal
THE CROPS WE GET DURING A DROUGHT MAY NOT BE HEALTHY. STRESSED CORN GETS A FUNGUS INFECTION THAT MAKES Aflatoxin potent natural carcinogen. Inserts self into DNA TURNS OFF tumor suppresser gene.
Compared with pregnancies before and after the wildfires, mean birth weight was estimated to be 7.0 g lower [95% confidence interval (CI): -11.8, -2.2] when the wildfire occurred during the third trimester, 9.7 g lower when it occurred during the second trimester (95% CI: -14.5, -4.8), and 3.3 g lower when it occurred during the first trimester (95% CI: -7.2, 0.6).
Increased vulnerability to disseminated disease 3rd trimester and immediately postpartum
New cases in eastern WA beyond previous endemic area.
Cryptococcus gattii- lung and CNS infection Vancouver Island, Pacific NW, mutation to highly virulent strain affecting immunocompromised and immunocompetent.37% higher than endemic countries. average incubation 6 months
Also being found in NW dead porpoises and dolphins, in one case transmitted in utero to fetus
Toxic pea soup. Most common for there to be multiple algal toxins. Safety limits set on basis of sole effect, no research on combined effects.

This slide shows how childrens visits to the emergency room for gastroenteritis (black line) match up with a model based on heavy rainfall (blue line). Majority of drinking water contamination cases in urban watersheds and nearly 70% of all gastroenteritis outbreaks occur after heavy rainstorms. Hospital admission of kids with diarrhea triples after heavy rain.
SUMMER ASTHMA CAMP STUDY SHOWS MDI USE DOSE RESPONSE AT OZONE LEVELS BELOW EPA LIMITS, increase in er visits
Causes asthma 3 sports=3x risk
CO2 acts as fertilizer, increases pollen production and allergenicity, and extends flowering season, spread of allergenic plants. Graph shows pollen production under preindustrial, current and projected future CO2 levels. Pollen levels predicted to double by 2040.
SEASON EXTENDING MOST IN HIGHER LATITUDES.
NE HAY FEVER SEASON NOW 10D LONGER
Mold causes increased ER visits for asthma and causes asthma. Recent birth cohort study higher levels of mold in home dust samples at 8 months of age doubled the risk of developing asthma by age 7
Mold more allergenic when grown at higher CO2..
Lead exposure can occur by inhalation and contact with airborne dust. Dust levels and air lead levels follow a seasonal pattern, rising when temperature is warm and soil is dry.
Soil is a significant source of lead exposure. About 30% of kids with elevated blood levels don't live in houses with lead paint. The correlation of lead poisoning incidence with areas with old housing could be because by virtue of their age, those communities have seen a lot of traffic and have a higher legacy burden of lead in their soil. Children's blood lead levels follow the same seasonal pattern which can be predicted by a model incorporating soil moisture and air temperature. The longer we have hot dry weather, the more exposure to lead kids will get.
You can see fromstandardized test scores the significant impact of lead levels between 5-10 mcg/dl on academic achievement. Currently about half a million US kids have BLL over 5. This chronic low level exposure cannot be terminated by home hazard abatement unless we are to cap or remove all soils from urban centers.
1999 national nutritional survey blood samples analysed last year for aflatoxin. 1% detectable. Higher in younger, Latinos, males, and immigrants.
INCREASES RISK OF LIVER CANCER ABOUT 7 TIMES HIGHER BUT WHEN COUPLED WITH CHRONIC INFLAMMATION LIKE HEP B OR C OR ALCOHOL, RISK IS 60 TIMES HIGHER.
NAFLD increasingly common risk factor for HCC in US. Childhood obesity increases risk of adult liver cancer 12-20%. currently affects 30% of US population, predicted to double by 2050
Biomarkers detected in Texas community with high prev HCC, related to corn tortillas and riceFDA allowed blending for feed in 4 states.
, deaths related to exertional heat stroke (EHS), the most severe form of EHI, appear to be on the rise [2]. STUDENT ATHLETE DEATHS from EHS were higher during the period from 2005 to 2009 than any other five year period over the past 35 years. CDC 9,000 PER YEAR
1991-1999- 17 child deaths/yr from being left in hot car
2002-2012 40/yr
So what's the forecast? Two columns
By 2047we will be outside of temperature range of the past 150 years. the coldest year will be warmer than our current hottest year. severe heat waves that used to occur once every 30 years, will happen annually and the number of extreme heat days will triple to quadruple. NE will have an extra 15-20 days over 95 by mid century, with heat waves lasting longer
HEAT RELATED DEATHS WILL quadruple nationally but in some urban areas increase as much as INCREASE 7 FOLD BY 2050
AGRESSION increased rates of assault, murder, domestic violence, suicides and psychiatric holds for danger to others
UC Berkeley metaanalysis of 60 studies- for each SD of increased temp
or decreased rainfall 4% increase in individual/small group violence,
14% increase in major conflicts. 2 SD INCREASE BY 2050.
We are facing a public health emergency. Public health- affects whole populations
Emergency- not because everyone will drop dead right away but because greenhouse gases are almost forever,
if we stopped now, it would take 300 hundred years for the ocean to absorb 60% CO2 because once the surface water gets saturated, have to wait for deep water to cycle up. Then the ocean is full. Removal of the next 10% takes 1000 years to react chemically with rock to become bicarbonate and get taken up into seashells, fall to the floor and get turned into limestone. The remaining 20% has to go back underground to coal and oil, which will take 10,000 years. Meanwhile, CO2 from natural sources is still being emitted and adding to what's there. If you add faster than you can remove, it keeps building up.
What happens to T? Global warming is like weight. Its easier to gain than lose. T would keep increasing for decades and then plateau. It wouldn't go down for 1000 years.
By 2030, 40% of adults will be obese, 44% will have cardiovascular disease, 1 of 5 will have DM
WHY? BECAUSE OUR FOSSIL FUEL ADDICTION IS MAKING US SICK
1/3 OF COLON CANCERS, 1/3 OF POSTMENOPAUSAL AND RECURRENT BREAST CANCERS, 1/3 OF HEART DISEASE AND DIABETES CASES PREVENTABLE BY PHYSICAL ACTIVITY
HALF ENDOMETRIAL CANCERS, 1/3 ESOPHAGEAL AND PANCREATIC CANCERS ATTRIBUTED TO OBESITY WHICH IS RELATED TO INACTIVITY
Ag system- fossil fuel, nitrogen fertilizer and water intensive. , using up our soil.
Ruminants produce methane. 20X Fertilizer produces nitrogen oxides 300X
Overconsumption of meat and corn sugars leads to CVD, cancer, obesity and diabetes.
3 IN NE: Belleview, Lincoln, and Omaha.
Cities across the country have almost a decade of experience and many successful projects to decrease energy waste and lower emissions.
So we know what to do and we know how to do it, but we don't have the political will in Washington to scale them up and get them done.

SO WHAT'S IN THE DOCTORS' PRESCRIPTION?
LUCKILY, ITS NOT THAT DIFFICULT. THE SOLUTIONS ARE COMMONSENSE, PAY FOR THEMSELVES IN FUEL AND HEALTHCARE SAVINGS, AND IMPROVE THE QUALITY OF LIFE. BUT OF COURSE THERES A CATCH,
Not problem deniers, solution deniers.
BUYING A PRIUS WON'T HELP
JOHN SNOW BECAME THE FATHER OF EPIDEMIOLOGY BY STOPPING A CHOLERA EPIDEMIC IN LONDON BEFORE THE GERM THEORY OF DISEASE WAS EVEN ESTABLISHED. DID HE DO IT BY GOING AROUND THE NEIGHBORHOOD TELLING EVERYONE NOT TO DRINK WATER? HEWENT TO HIS LOCAL GOVERNMENT AND GOT THEM TO TAKE THE HANDLE OFF THE PUMP. “The pestilence was stayed.”
Take the handle off the pump is not something you do at your own house,
ZERO ENERGY HOME SEATTLE, MAKES UP USE WITH SOLAR. 75% CONSERVATION AND 25% GENERATION.
Atlanta Olympics- traffic decreased 20%, ozone decreased almost 30%, and kids ER visits for asthma down over 40%.
The health cost of fossil fuel addiction is enormous. Globally 400,000 people a year die as a result of climate change (90% are children) but 4.5 million die from lung disease, CVD and cancer from carbon related air pollution. We spend more on the health consequences of fossil fuel than we do on fossil fuel itself.
Closing all coal burning power plants in the US would save 13,200 lives and prevent nearly 10,000 hospitalizations and more than 20,000 heart attacks each year with an annual health savings of more than $100 billion per year
For every ton of CO2 emissions we eliminate, even counting the cost to do it, we come out economically ahead.
WE NEED TO GET PEOPLE OUT OF THEIR CARS. EVEN WITH IMPROVED FUEL ECONOMY, THE REDUCTION IN EMISSIONS WILL BE OUTWEIGHED BY the projected INCREASE IN THE NUMBER OF CARS and miles driven.
WE GET WHAT WE PAY FOR: HIGHWAYS. ONLY 1% FOR ACTIVE TRANSPORT AND WE HAVE TO FIGHT TO KEEP IT.
Public transit: equalize the federal match, invest till people are using it. NY and transit
40% of daily trips are under 2 miles. Put the things we need within walking distance, separate the people from the cars, Mass transit mixed mode.
Public transport – 30% get recommended exercise vs 80% of total pop that doesn't.
Why should each person take 1-2 tons of steel if they're all going to the same place. Highly functional system, investment, subsidy.
Increased average daily time spent on active transport from 4 to 22 minutes/d SF bay area
Decrease
14% heart disease, stroke, and diabetes
6-7% dementia and depression
5% breast and colon cancer
1.4 -22 billion dollars/year saved
Midwestern metrop areas- 50% short trips by bike save over $5 billion in health spending per year: $3.8 billion/year saved due to health benefits of exercise and $2.5 billion due to benefits of cleaner air.
Nutritionally in the US we get what we pay for. We're subsidizing corn for feed and ethanol and that's what we get. !% of crop subsidies goes for produce. Just got on crop insurance this year.
We know that lowering prices of produce increases consumption. Align subsidies with federal dietary recommendations. 40% of food is wasted.
Revising use by labelling
Tax credits for farmers who donate cosmetically unsellable food.
Lets make energy out of waste instead of methane.
Heavy meat eaters eat an avg 700 cal more/d
Decrease cancers by 10%, heart disease by 20%, 25% less diabetes
I'd like to call your attention to one small problem:
While a STRONG MAJORITY OF US CITIZENS WANT CLIMATE ACTION NOW, even if other countries don't act, and even if it costs us some money
.They are not representing us, their constituents on this critical issue. If we don't wake them up or kick them out, they will create a living hell on earth.
25% of Americans surveyed are willing to join a campaign to straigten out Congress. They're waiting for someone in their community to step forward.
Call, write, lobby, go to candidate debates and ask what they're going to do about climate change. Most important be public, and create opportunities for others to join you.
