Climate Change Effects and Predictions

The video discusses the 2013 IPCC climate change report, highlighting the unequivocal evidence of global warming, the rise in greenhouse gases, and the significant human influence on climate change. It addresses media misinterpretations about a 'pause' in warming and presents future climate projections. The video concludes with a call for world leaders to focus on climate issues.

What is the primary purpose of the IPCC as established by the United Nations?

• To entertain the public with climate stories

• To provide world leaders with facts about global warming

• To create documentaries about climate change

• To organize climate change protests

• It is a myth

• It is a temporary phenomenon

• It is unequivocal

• It is reversible

What did some media outlets incorrectly report about global warming?

• That it had no effect

• That it had reversed

• That it had paused

• That it had accelerated

What are the main gases contributing to the greenhouse effect?

• Oxygen, nitrogen, and argon

• Hydrogen, helium, and neon

• Carbon dioxide, methane, and nitrous oxide

• Helium, neon, and krypton

How much higher are current CO2 levels compared to the industrial revolution?

• 50% higher

• 20% higher

• 30% higher

• 40% higher

What is the likelihood that human influence is the dominant cause of observed warming since the mid-20th century?

• 90% to 95%

• 70% to 80%

• 50% to 60%

What is virtually certain according to the IPCC regarding future climate conditions?

• Decreasing global temperatures

• More frequent extremes of heat

By how much could global average temperatures rise over the next 20 to 25 years?

• 0.1 to 0.2 degrees Celsius

• 0.3 to 0.7 degrees Celsius

• 1.0 to 1.5 degrees Celsius

• 2.0 to 2.5 degrees Celsius

What could be the potential temperature increase by 2081 if greenhouse gas emissions are not reduced?

• 1.5 degrees Celsius

• 2.5 degrees Celsius

• 3.5 degrees Celsius

• 4.8 degrees Celsius

What does the report say about the persistence of climate change effects?

• They will persist for many centuries
