Study Notes
Week 1
- Scientific method involves observing, explaining, and testing.
- Observation enables identification and focus on relevant facts and phenomena.
- Careful observation considers relevant and irrelevant phenomena, avoiding biases.
- The steam engine was crucial to the Industrial Revolution.
- Increased manufacturing, income, and population growth resulted from the steam engine.
- However, conditions in crowded cities worsened with pollution (coal), and lack of sanitation (cholera, etc).
- Despite these issues, advances in agriculture and food distribution led to a population surge.
Week 2
- Human population has doubled every 138 years due to decreases in mortality.
- The Baloney Detection Toolkit (BDTK) is a set of questions to evaluate the validity of information.
- Key to applying BDTK is having a skeptical mindset.
- Science relies on falsifiable explanations, not speculation.
- Biases affect critical thinking and need awareness.
- Recognizing biases can lead to more objective conclusions.
Week 3
- Confirmation bias is the tendency to seek out information that confirms pre-existing beliefs.
- Availability bias tendencies to use information we can quickly recall.
- Illusory truth bias is the tendency to believe false information to be correct after repeated exposure.
- BDTK is a toolkit to help assess the reliability of a source. (Who is behind the information and why? What is the evidence for the claims?)
- Identifying the author, their background and organization are crucial aspects of assessing a source.
- Evaluate websites for indicators of reliability.
Week 4
- Testing scientific explanations involves proposing, performing experiments, and revision/abandonment of hypotheses if necessary.
- Explanations must be falsifiable.
- Key concerns of observation are: Have we overlooked anything?
Week 5
- Epistemic responsibility is the duty to know how scientific inquiry works and to justify beliefs with evidence.
- Scientific inquiry is a way of interpreting the world.
- Climate change studies are necessary for more effective understanding and action.
- Climate change is attributed to increased CO2 emissions from burning fossil fuels.
Week 6
- Climate = long-term weather conditions, weather = short-term conditions.
- Global warming describes the shift in weather patterns associated with climate change.
- Scientific consensus on climate change is overwhelmingly that human activities are a major cause.
- Scientific method forms an objective framework for understanding facts and testing hypotheses.
Week 7
- Scientific consensus is reached through critical review, debate, and testing among experts, not an appeal to authority.
- The scientific community vs scientific consensus is a related but distinct concept
- Public policy and scientific evidence are distinct concepts
- The idea of a "disconnect between rhetoric and action" is relevant to climate change policy.
Week 8
- Climate models are large computer simulations with complex physical processes.
- Hindcasting demonstrates that climate models adequately reproduce past conditions.
Week 9
- Biodiversity loss is a global phenomenon.
- Loss of biodiversity can be linked to human settlement and resource exploitation.
Week 10
- Establishing connectivity of nature can aid biodiversity preservation
- Case studies illustrate the need for planned actions to connect fragmented nature reserves and support biodiversity.
Week 11
- Carbon emissions are a significant factor in climate change.
- The Industrial Revolution is the starting point for accelerating the extraction and use of carbon sources increasing atmospheric CO2.
- Worldwide population growth exacerbates carbon emissions.
- Greenhouse gas emissions are crucial to estimate climate change.
Week 12
- Fallacies in the name of science are instances of flawed reasoning, not necessarily an indicator of a discipline lacking scientific rigor.
- Using BDTK to evaluate claims can identify flawed reasoning, such as misrepresenting the scientific consensus, appeal to authority, and false cause fallacies.
- Crop circle controversy exemplifies pseudoscientific claims and how they can be challenged using scientific methodology.
Week 13
- Scientific consensus can change over time.
- Historical records can be used to determine past scientific beliefs and knowledge.
Week 14
- Issues relating to environmental topics are inherently complex and need to be examined using various analytical tools, not just scientific ones.
- There is a multidisciplinary nature to global assessments which involve politics, economics, and culture in addition to environmental science.
