evidence of climate change

• What is the primary goal of the evidence-based approach to climate change studies?

  To understand climate change
• The evidence-based approach relies on data
• The evidence-based approach uses only qualitative data to study climate change.

  False
• Steps in the evidence-based approach to studying climate change:

  1️⃣ Gather empirical data

  2️⃣ Analyze data using scientific methods

  3️⃣ Interpret results

  4️⃣ Form conclusions based on evidence
• Match the type of evidence with its example:

  Historical records ↔️ Old diaries and logs

  Ice core data ↔️ Analysis of trapped gases

  Satellite imagery ↔️ Monitoring ice melting
• What is the purpose of studying historical records as evidence of climate change?

  To track past trends
• Historical records provide insights into past climate conditions
• Historical records are always accurate and unbiased.

  False
• Steps in analyzing ice core data:

  1️⃣ Drill and extract ice cores

  2️⃣ Analyze trapped gases

  3️⃣ Determine past atmospheric conditions

  4️⃣ Compare with current data
• What do ice cores reveal about past atmospheric conditions?

  Composition of gases
• Ice cores provide a continuous record of climate change
• Ice cores are only useful for studying climate change in polar regions.

  False
• How is satellite imagery used as evidence of climate change?

  To monitor ice melting
• Satellite imagery helps track changes in ice extent
• Satellite imagery can only detect changes in surface temperature.

  False
• What are the limitations of using historical records as evidence of climate change?

  Incomplete data
• Historical records may suffer from biases
• Ice core data is immune to human error.

  False
• What is a key limitation of satellite imagery as evidence of climate change?

  Depends on weather conditions
• Satellite imagery is affected by atmospheric conditions
• Steps in comparing evidence from different sources:

  1️⃣ Gather data from multiple sources

  2️⃣ Identify common trends

  3️⃣ Analyze discrepancies

  4️⃣ Form a comprehensive understanding
• Why is it important to compare evidence from multiple sources in climate change studies?

  To increase accuracy
• Comparing evidence helps identify consistent trends
• Evidence from different sources always agrees perfectly.

  False
• What is the role of climate models in studying climate change evidence?

  To simulate future scenarios
• Climate models use mathematical algorithms
• Climate models are 100% accurate in predicting future climate conditions.

  False
• Match the climate change evidence with its application:

  Historical records ↔️ Study past climate variability

  Ice core data ↔️ Analyze atmospheric changes over time

  Satellite imagery ↔️ Monitor ice loss in real-time
• The last ice age ended approximately 25,000 years ago.
• What does ice core data reveal about changes in temperature over the last 11,000 years?

  Past climate conditions
• Ice cores contain trapped air bubbles that provide information about past CO₂ levels and temperatures.
• Preserved pollen allows scientists to determine which plants were located where, providing evidence of past climate conditions.
• What type of historical evidence is used to study past climate conditions?

  Diaries and art
• Historical sources like diaries and paintings may be subjective and therefore less accurate.
• Each ring of a tree shows a year's growth, which can indicate past climate conditions.
• How do warmer and wetter years affect tree rings?

  Rings are larger
• Fossilised tree remains can be used to examine the climate over thousands of years.
• What evidence did paintings of frost fairs on the River Thames provide about the 19th century climate in London?
