Global Warming - Evaluating the Evidence

The video discusses the unprecedented levels of carbon dioxide in the atmosphere and the methods used to measure historical and current global temperatures, including satellite technology and ice core analysis. It highlights the challenges in monitoring global temperatures and sea levels, the increase in extreme weather events, and the alarming rate of glacier and Arctic ice melting. The video concludes with a call to action, emphasizing the need for global efforts to address climate change, supported by evidence accepted by the United Nations.

What method is used to determine past global temperatures from Antarctic ice cores?

• Tree ring analysis

• Oxygen isotope analysis

• Radiometric dating

• Carbon dating

How have satellites improved our ability to measure sea level changes?

• By monitoring marine life populations

• By tracking the movement of tectonic plates

• By allowing precise measurements of sea level changes

• By providing data on ocean currents

Which region has experienced more frequent and intense storms in the 21st century?

• The Mediterranean

• The Caribbean

• The Arctic

• The Sahara

What is the predicted future for Arctic ice by the end of this century?

• It will remain stable

• It will completely disappear

• It will increase in size

• It will be ice-free for a few months in summer

What is the global consensus on the evidence of global warming?

• It is considered a natural phenomenon

• It is only accepted by a few scientists

• It is accepted by the United Nations and most countries

• It is still debated
