13 Misconceptions About Global Warming

What is the main difference between "global warming" and "climate change" as explained in the video?

• Global warming refers to the overall increase in Earth's average temperature, while climate change includes broader impacts like extreme weather and ocean changes.

• Global warming is a natural process, while climate change is caused by humans.

• Global warming only affects land temperatures, but climate change affects oceans.

• Global warming is no longer happening, so scientists changed the name to climate change.

Besides rising global temperatures, what other signs indicate that the Earth is warming?

• Decreasing sea levels and increasing ice mass in Antarctica.

• Increasing volcanic activity and brighter sun.

• Rising sea levels, melting ice in Greenland and Antarctica, and declining Arctic sea ice.

• More frequent earthquakes and changes in wind patterns.

How do human CO2 emissions contribute to climate change, even though natural processes release more CO2 annually?

• Human CO2 is more potent than naturally released CO2.

• Natural CO2 is quickly absorbed by plants, while human CO2 stays in the atmosphere.

• The natural system was in balance, absorbing as much CO2 as it released, so human emissions add extra CO2 to the atmosphere.

• Natural processes only release CO2 during specific seasons, while humans release it all year.

How does water vapor contribute to the warming effect caused by increased CO2 in the atmosphere?

• Water vapor directly causes CO2 levels to rise.

• Warmer temperatures allow the atmosphere to hold more water vapor, which is a potent greenhouse gas, creating a positive feedback loop.

• Water vapor cools the Earth by reflecting sunlight.

• Water vapor is not considered a greenhouse gas.
