Bearded Dragons and Climate Change Effects

The SciShow Talk Show features Steve Running, a Regents Professor Emeritus at the University of Montana, discussing his career path from a tree physiologist to working with NASA on Earth Observing Systems. The conversation covers climate change, food production, bioenergy, and the impact of sea level rise. Additionally, the show explores a study on bearded dragons and how climate change affects reptiles.

What is Steve Running's main message about choosing a college major?

• Changing majors is not advisable.

• It's crucial to choose the right major for your future career.

• Your major will determine your entire career path.

• You can end up in a different field than your major.

What is the primary focus of NASA's Earth Observing System?

• Studying the stars and outer space.

• Monitoring plant growth and the biosphere.

• Exploring other planets for life.

• Developing new satellite technologies.

How does NASA measure groundwater depletion?

• By sending divers to measure water levels.

• Through satellite measurements of gravitational changes.

• Using weather balloons to track water vapor.

• By using drones to collect data.

What is the significance of the GRACE satellite mission?

• It measures the Earth's magnetic field.

• It tracks changes in Earth's gravity to monitor groundwater.

• It observes the ozone layer.

• It studies the sun's radiation.

What is a potential solution to the food production challenge mentioned?

• Increasing the use of pesticides.

• Improving agricultural efficiency and reducing waste.

• Expanding urban areas into farmland.

• Relying solely on bioenergy.

What is a major concern related to climate change discussed in the video?

• Increased volcanic activity.

• More frequent meteor showers.

• Sea-level rise affecting coastal cities.

• Decreased solar activity.

Why is sea-level rise considered a significant threat?

• It will increase the Earth's rotation speed.

• It will impact major coastal cities and is less reversible.

• It will lead to the extinction of all marine life.

• It will cause more earthquakes.

What adaptation challenges do reptiles face due to climate change?

• They are migrating to colder regions.

• They are becoming more intelligent.

• They are not adapting quickly enough to rising temperatures.

• They are thriving with more warmth.

What unique ability do bearded dragons have that was studied?

• They can fly short distances.

• They can survive without water for months.

• They can change colors like chameleons.

• They can mimic behaviors they observe.

What was the result of the study on bearded dragons incubated at higher temperatures?

• They learned tasks more quickly.

• They became more aggressive.

• They grew larger than average.

• They struggled with cognitive tasks.
