History: Anti-Litter & Anti-Pollution Campaigns Begin
  • 1960s: Espera De Corti Iron Eyes Cody
current events we have impacted the planet
Current Events: We have Impacted the Planet
  • Its about more than litter and pollution
  • It has become an issue of fundamentally altering the climate on the entire planet
  • Global warming will raise the overall average temperature, but that will change patterns so that some areas get wetter, some drier, and some actually get colder, such as Northern Europe if the Atlantic Gulf Stream is again disrupted
un international panel on climate change ipcc trends in conclusions
UN International Panel on Climate Change (IPCC): Trends in Conclusions

1990 Uncertainties and some evidence.

1995 “Evidence suggests a discernible human influence on global climate.”

2001 “Most warming of the past 50 years is likely (>66%) attributable to human activities.”

2007 “Warming is unequivocal, most warming in the past 50 years is very likely (90%) due to increases in greenhouse gases.”The Physical Basis of Climate Change

global climate change is speeding up
Global Climate Change is Speeding Up
  • Since the IPCC began, scientists have recorded “much stronger trends in climate change,” like a recent melting of polar ice that had not been predicted.
  • “If there’s no action before 2012, that’s too late. What we do in the next two to three years will determine our future. This is the defining moment.”
    • IPCC Chair Rajendra Pachauri — scientist and economist
actual changes show human forcings impacts exceed natural forcings
Actual Changes Show “Human Forcings” (Impacts) Exceed “Natural Forcings”

Computer models compare changes expected through natural impacts (solar and volcanoes) alone with those that include human impacts, and both with actual observed changes. Actual observations best match the models that include human impact.

Models using both “natural” and anthropogenic (human) forcings

Models using only “natural” forcings

Global Impacts: Example, Tienamen Square, Beijing, China

A man flying a kite in Tiananmen Square last Boxing Day. Pollution levels on a typical day in Beijing are five times above World Health Organisation standards for safety, and are worse in the summer, worrying Olympic athletes. Three million cars and coal-fired factories, steel mills and skyscraper builds throughout the city have caused the smog. To ‘clean’ the air for the Olympics, Chinese authorities will take 1m cars off the road and are closing factories a month in advance. Photograph: Oded Balilty/AP

What Actually Happened, 35% Melt by 2007: Complete Arctic Melt now Predicted by 2013, or even 2008)

and this just in
And This Just In:
  • 160 square miles of Antarctica’s Wilkins ice shelf has been lost since the end of February, 2008 leaving the ice interior now ‘hanging by a thread’. “We predicted it would happen, but it's happened twice as fast as we predicted.”
    • Professor David Vaughan of the British Antarctic Survey (BAS).
  • The land-based ice that was held back by the sea-ice is now open to slipping into the ocean and melting.
local impacts sea level rise
Local Impacts:Sea Level Rise

SEA LEVEL RISE IN CALIFORNIA: Sea level rise provides a physical measure of possible oceanic response to climate change. This indicator shows the rising trend in sea level measured at two California stations: San Francisco and La Jolla. Long-term data from 10 of 11 California stations show increases in sea level at varying rates. The rise in global sea level is attributed to the melting of mountain glaciers and ice sheets around the globe and the thermal expansion of ocean water. Sea level rise is not a new phenomenon, having been a major natural component of coastal change throughout time. Differences in sea level rise along the coast can occur because of local geological forces, such as land subsidence and plate tectonic activity. However, there is concern that the rate of sea level rise may increase with possibly increased global warming. http://co-ops.nos.noaa.gov

local impacts invasive species
Local Impacts: Invasive Species
  • Coastal communities climate change
  • Humboldt squid (which can grow up to 7’ long) have spread up the California coast as ocean waters warm up. They eat local fish.
  • "It's the latest in a long series of bad news for fishermen," said Lou Zeidberg, Stanford University.
layers of change
Layers of Change
  • Climate change is a “macro” result of human behavior on our planet and ourselves.
  • Air pollution, water pollution, increases in wastes, including toxic wastes harm our health directly, and change the environment too.
  • The science simply confronts the fact that effects we think of as small and local also create macr global changes.
  • Smog not only harms our lungs directly, it impacts the planet too.
climate sensitive diseases
Climate-Sensitive Diseases
  • Human induced climate change "is likely to have wide-ranging and mostly adverse impacts on human health, with significant loss of life."
    • 2007 IPCC Report
  • Harvard Medical School researchers have linked recent U.S. outbreaks of dengue ("breakbone") fever, malaria, hantavirus and other diseases to climate change.
climate sensitive diseases23
Climate-Sensitive Diseases
  • Increased sea level and sea surface temperatures can lead to higher incidence of water-borne infectious and toxin-related illnesses such as cholera and shellfish poisoning;
  • Zooplankton proliferate in warmer water temperatures; are a cholera carrier. Cholera killed 120,000 world-wide people in 1995, mostly children.
  • Encephalitis, another illness with strong links to warmer temperatures, is on the rise. Since 1987 California, Arizona, Texas, Florida, Mississippi, New Orleans, and Colorado have had major outbreaks.

old diseases in new places
Old Diseases in New Places
  • Paul Epstein, MD, worked in Africa, now at Harvard Medical School, said scientists haven’t been worried enough. "Insects are exquisitely sensitive to temperature changes.”
  • "Things we projected to occur in 2080 are happening in 2006. What we didn't get is how fast and how big it is, and the degree to which the biological systems would respond. Our mistake was in underestimation.”
  • www.washingtonpost.com/wp-dyn/content/article/2006/05/04/AR2006050401931.html
old diseases in new places26
Old Diseases in New Places
  • Disease-carrying mosquitoes can now survive in new places. Mosquitoes that carry dengue fever viruses were limited to elevations below 3,300 feet but now appear at 7,200 feet in the Andes of South America.
  • Dengue Fever has re-emerged in the Caribbean.
  • Malaria has been detected in new higher-elevation areas in Indonesia.
  • Diseases like West Nile Virusnow spread farther when they get the chance (e.g., via airlines)
spread of tropical diseases west nile virus example

Spread of Tropical Diseases: West Nile Virus Example

1999 to 2007: West Nile Virus is spread by mosquitoes that were able to invade the U.S. and even into Canada as small changes in weather made it easier for them to survive in these new locations.

Linkages: Global Climate Change and Chronic Diseases
  • Expansion of temperate climates leads to spread of viruses that lead to auto-immune diseases.
  • Air pollution directly causes respiratory and other ailments and also leads to global warming. Respiratory problems lead to reduced physical activity that leads to obesity, diabetes, and other chronic diseases. All of these things are linked.

rethinking change

Rethinking Change

Rethink and Reset Values and Behavior: Think Locally, Act Globally

Reduce the Flow: Adjust Things

Buy Some Things

Stop Buying Other Things

. . . and save money while we do all this!

rethink reset values behavior
Rethink & Reset Values & Behavior
  • Is “cheapest” always the least expensive?
  • Is expensive always the best?
  • Do we really need it at all?
  • Let’s talk about the balance sheet. Examples:
    • Plastic cups & dishes vs washing them.
    • Community meetings: Must it be highly packaged lunches? Ever see our trash at the end of a day-long meeting?
    • 800,000 plastic bottles used in the US each DAY
    • Change values on purchases
reduce the flow
Reduce the Flow
  • Set and measure environmental goals.
    • Require vendors to meet sustainability standards (and meet them ourselves)
    • Turn off lights, turn on only one switch, not two
    • Turn off computers, printers, machines that “sleep” (at 30% of “on” energy use) Save over 1,000 lbs of CO2 and $256 per year.
    • Stop using plastic and paper cups, plates, etc.
    • Report leaking faucets at work and fix them at home. Turn off faucets.
reprogram ourselves and our kids
Reprogram Ourselves and Our Kids
  • Yes, [child’s name], this is another teaching moment!
  • Learn about global warming, and how it relates to global justice.
  • Learn, Teach, Do! (Ignore when our kids whine “but mom, but dad!”)
  • Think outside the box, get creative.
  • (Turn off the TV!)
just stop buying stuff
Just Stop Buying “Stuff!”
  • We have been programmed to believe we always need the newest, best, hottest, in season things. (They get our money, we get their stuff.)
  • We don’t need this much stuff!
  • Experiment: Take a week or month and just stop buying stuff. Instead of “shopping” or watching TV, go for a walk or hike, read a book.
  • Save thousands each year, reduce massive amounts of energy and waste. Save the planet!
what ventura county public health is already doing
What Ventura County Public Health is Already Doing
  • Buying recycled products
  • Recycling used products like toner cartirdges and paper
  • Rain water drain filters in the 2240 parking lot reduce pollution to the ocean
  • Reducing waste, water use
  • Turning off the lights!
  • Participating with other County agencies in plans to reduce, recycle, reuse
what s going to happen if we don t make some changes
What’s Going to Happen If We Don’t Make Some Changes?
  • Increased global demand for energy; food prices will continue to rise;  already scarce water will become even harder to find, and air quality will get worse.
  • Locally, increasing temperatures and decreased waterfall will likely strain limited water sources, increasing wildfires and air pollution. Diseases are likely to emerge for people and other species.
  • Children, the elderly, the poor, and those with chronic health conditions are most susceptible to health impacts of climate change, and strategies for managing climate change impacts should take their unique challenges and needs into account.
what s going to happen if we don t make some changes53
What’s Going to Happen If We Don’t Make Some Changes?
  • Chronic and communicable diseases will spread.
  • Air pollution, for example, causes health problems directly, but also causes global climate change, which will lead to even more health problems.
  • Sea levels will rise, weather patterns will shift
what s going to happen if we don t make some changes54
What’s Going to Happen If We Don’t Make Some Changes?
  • Rising sea level would affect the Ventura County coastal zone in several ways. It would intensify storm surges, resulting in accelerated beach erosion and shoreline recession. It would reduce fresh water supplies, wetlands, dunes and protective shorelines, and it would release soil-bound chemicals from agricultural land. It could result in the loss of natural habitats such as the Ormond Beach wetland.
      • Angela Constable, LA Times, 9/6/1998

Five Minute Challenge
  • Take five minutes and write out at least one idea for how we can reduce global warming, energy use, or pollution in our workplaces.
  • At your next staff meeting or dinner at home, discuss how you can reduce global warming, energy use, or pollution.
