What is the science supporting climate change? (2)

1. earth is warming 2. rising global T have been accompanied by changes in rainfall, intense rain, more floods, and droughts, as well as more frequent and severe heat waves

How can extreme weather events affect mental health? (6)

1. following disasters, mental health problems increase - "a common reaction to abnormal events" 2. stress mediated maternal fetal outcomes including pre-term birth, low birth weight, and maternal complications 3. suicide rates rise with high T 4. dementia is a risk for hospitalization/death during heat waves 5. patients with severe mental illness are at risk during hot weather b/c their medications may interfere with temperature regulation or cause hyperthermia 6. distress associated with environmental degradation and displacement and the anxiety and despair that knowledge of climate change might elicit in some people

What are 3 pillars of food security?

What are 3 factors shaping climate change beliefs?

1. many factors shape views of climate change 2. economic trends, cultural norms, beliefs of family and friends, and value and political ideology, often exercised through heuristics that bypass evidence 3. media coverage

By mid 21st century, climate change may what? (in terms of food security) (4)

1. redistribute and reduce marine biodiversity in sensitive areas resulting in decreased productivity (high confidence) 2. negatively impact production of grains in tropical and temperate regions if T increase 2 deg (medium confidence) 3. T increases of 4 deg C +, combined with increased food demand, pose large risks to food security globally (high confidence) 4. reduce renewable surface and groundwater in most arid subtropical regions (robust evidence, high agreement)

What are 3 factors in increased heat morbidity?

1. urban heat islands (due to concrete/asphalt) 2. increased urbanization 3. aging population

Transportation sector produces how much of Us greenhouse gases?

1/3

What fraction of US residents believe that climate change is occurring? - what % of those believe humans cause it?

2/3 - 40%

Agriculture, livestock, and forestry make up what % of all green house gas emissions?
