Strange Days on Planet Earth: The One Degree Factor Experiences/Observations Patterns in Data Explanation Temperature measurements in the Arctic Rising average temps in the Arctic Possibly looking at threshold where caribou cannot recover Porcupine herd census data (from satellite photos—supported by Gwitchen observations) Caribou population decreasing (190 K to 120 K since 1989) SUMMER Caribou observations (behavioral & physical): time allotment, fat content, offspring produced, mortality rates Caribou avoid bottomlands (where more reliable food sources are), build up less fat in summertime, produce less calves, increased adult deaths Habitat observations: food abundance, daily temps, available water, mosquito population. More warm days, longer insect breeding season, larger swarms of mosquitoes WINTER Caribou observations (behavioral & physical): time allotment, offspring produced, mortality rates, feeding strategies Habitat observations: food availability, daily temps, predation, precipitation levels. Zooplankton observations: behavior, metabolism, distribution, anatomy Delayed migration, delayed calving, harder to avoid predators, Rain in December, appearance of “blood trails”, ice build-up over food sources, more snow in winter, lichen buried deeper, increase in violent and unseasonable storms (spring blizzards) Daily up and down movement of zooplankton Zooplankton avoid predators by ascending after dark Krill population 20% of 1950’s, yet rebounds in late 90’s Observations of H20 temps in the Pacific Cold water off Oregon = zooplankton increase, warm water off Oregon = zooplankton decline Census of tidal pools, temperatures of tidal pools, body temperature of tidal pool inhabitants, heart rate data of crabs Mix of species changing in CA tide pools Examination of kids (doctors) Examination of coral, atmospheric samples (scientists) Measurements of surface area of Lake Chad (satellite photos) Regime shifts: warm water affects flow on nutrients from depths High body temperatures in tide pools Crab heart rates crash 2 degrees F above current temps Asthma levels rise in Trinidad Coral sea fan disease in St. John’s Increased levels of dust to clean Lake Chad reduced to 1/20 of former areas Aspergillis possible cause of sea fan disease Asthma admissions correlated with African dust Cultural observations: abandoned fishing boats, research lab, communities rebuilding on channels Agriculture and livestock replacing fishing as source of livelihood Drought has caused increased dust in Africa Dust going toward Americas Atmospheric pressure measurements Satellite photos North Atlantic oscillation staying in intense phase every winter for the past 20-30 years Climate model changes with increasing concentrations of greenhouse gases Wind measurements Paths of storms Rainfall measurements Dust going toward Americas Increasing temperature of Indian Ocean increases rainfall over Indian Ocean Heat from Indian Ocean fixes North Atlantic oscillation, mobilizes dust in Sahara, affects children and sea fans in Caribbean Notes: Questions for further discussion: 1) What do we, as a society, need to do as a response to the scientific findings discussed? 2) What is the responsibility of scientists in the larger discussion of climate change? 3) What is our role as science educators in regards to environmental literacy and the larger societal conversations about science?
