The Science of Climate Change

The video explores climate and weather patterns, explaining the gradual nature of climate change and its causes, including human activities like burning fossil fuels. It details the greenhouse effect and presents evidence of climate change, such as rising temperatures and melting ice. The video discusses the impact on agriculture, ecosystems, and energy needs, highlighting the importance of adaptation and reducing fossil fuel use to mitigate climate change.

What is the primary difference between weather and climate?

• Weather is global; climate is local.

• Weather is predictable; climate is not.

• Weather changes slowly; climate changes quickly.

• Weather is short-term; climate is long-term.

How do scientists study past climates?

• By observing animal migration.

• By examining sedimentary rocks and fossils.

• By analyzing current weather patterns.

• By measuring ocean currents.

What natural factor can cause short-term climate change?

• Ocean pollution

• Volcanic eruptions

• Urbanization

• Deforestation

What is the greenhouse effect?

• The cooling of the Earth's surface by clouds.

• The absorption of sunlight by oceans.

• The reflection of sunlight by ice caps.

• The trapping of heat by gases in the atmosphere.

Which human activity is primarily responsible for increasing greenhouse gases?

• Recycling

• Planting trees

• Burning fossil fuels

• Fishing

What is a sign of climate change related to precipitation?

• Complete absence of droughts.

• Changes in rain and snow patterns.

• Uniform increase in rainfall worldwide.

• Decreased snowfall in all regions.

How does climate change affect sea levels?

• By decreasing ocean salinity.

• By causing sea levels to drop.

• By increasing sea levels due to melting ice.

• By stabilizing sea levels.

What impact does climate change have on agriculture?

• It has no effect on agriculture.

• It can both positively and negatively affect crop growth.

• It only benefits crop growth.

• It only harms crop growth.

How might climate change affect energy needs?

• It will have no impact on energy needs.

• It will increase the demand for electricity for cooling.

• It will increase the demand for heating in winter.

• It will decrease the need for air conditioning.

What is a crucial step in addressing climate change?

• Stopping all technological advancements.

• Ignoring climate models.

• Reducing greenhouse gas emissions.

• Increasing fossil fuel use.
