ux: here is sway (no.4)

Derick and I chose to work under the Climate Reality Project (site here), which seeks to educate people on climate change and to counter climate change denial campaigns. People who usually view their site are female, and primarily browse the site at home. They also have some sort of college education. 
>>to view more in-depth info on Climate Reality, view previous post.

We researched general information on climate change:

  • WHAT IT IS
    • climate change can refer to the change in the "statistical distribution of weather patterns when that change lasts for an extended period of time." 
    • however, the definition we are using are climate change caused by human activity as opposed to by the Earth's natural processes
  • CAUSES (anthropogenic)
    • increasing concentration of greenhouse gases
      • primarily CO2: burning fossil fuels
    • mass deforestation
    • waste and other pollution
      • prevents the environment to be able to withstand climate change
  • IMPACTS (vary depending on region)
    • changes in global temperature
    • rise of sea level
    • change in pattern of precipitation
    • expansion of deserts
    • retreating of glaciers
    • drastic climate events
      • heat waves
      • droughts
      • heavy rainfall
      • heavy snowfall
      • ocean acidification
      • species extinction
    • how effects humans:
      • threatens food security by decreasing of crops
      • loss of habitat due to inundations
  • SOLUTIONS
    • trying to limit the magnitude of damage caused by carbon emissions
      • reforestation and extending green areas
      • creating economic motivation for entities that make an effort to create more efficient energy sources
    • energy efficiency
    • adaptation
      • effects will take time to diminish, so have to adapt to climate change in order to withstand these changes
      • developing countries will suffer the most due to economic complications
    • future climate engineering
  • EVIDENCE OF CLIMATE CHANGE
    • global sea level rose 17 centimeters in last century
      • rate in last decade = double the rate of last century
    • earth has warmed since 1880
      • mostly occurred since 1970s
      • surface temperatures continue to overall increase
    • top 700 meters of ocean are .302 degrees fahrenheit warmer since 1969
      • antarctic ice shelf mass loss
    • greenland and antarctic ice sheets decreased in mass
      • greenland: lost 150 - 250 cubic kilometers of ice between 2002 - 2006
      • antarctica: lost 152 cubic kilometers between 2002 - 2005
    • extent and thickness of Arctic sea ice declined rapidly over last several decades
      • satellite images
    • glaciers are retreating everywhere including the Alps, Himalayas, Andes, Rockies, Alaska, Africa
    • number of record high temperature events in the U.S. has been increasing
      • number of record low temps decreasing since 1950
      • increasing numbers of intense rainfall events
    • acidity of surface ocean increased by 30 percent since Industrial Revolution
    • amount of carbon dioxide absorbed by upper layer of oceans is increasing by 2 billion tons/year
    • satellite observations show amount of spring snow cover in Northern Hemisphere has decreased over past 5 decades
      • snow melting earlier
  • DENIAL CAMPAIGNS
    • campaigns designed to “confuse the public about the level of agreement among climate scientists”
    • A dismissal of global warming and its connection to human behavior
    • even though global warming is scientifically proven, denial campaigns seek to instill doubt in people
    • has contributed to government inaction and lowered public concern
    • there’s a gap between public perception and reality
    • global warming skepticism is increasing: only 65% of U.S. citizens think of climate change as serious to somewhat serious (in 2007, 77% of the U.S. population believed climate change to be a serious issue)
    • wealthy Republicans are more likely to dispute climate change
    • Mostly associated with:
      • fossil fuels lobby
      • Koch brothers
      • industry advocates
      • free market think tanks
    • Arguments:
      • global warming is not occurring
      • global warming is not by human action 
      • it is not because of carbon dioxide
