Question:
(1) According to this documentary, what are some of the most significant artefacts of
global climate change as the nations and societies have been experiencing during the
last 10 years?
(2) Why is the climate in the Bay of Dinard (Brittany, Northern France) and in the Gulf
of St. Lawrence (Northern Canada), which happen to be located at the same latitudes
in the Northern Hemisphere, very different?
(3) What is the “Gulf Stream”? Describe it based on what you have heard in the
beginning of this documentary.
(4) Where does the Gulf Stream originate and where does it end geographically? What
is its other name?
(5) Who named the Gulf Stream for the first time and when? Why was this person
concerned about the Gulf Stream?
(6) Give two examples of the significant impact of the Gulf Stream on marine life and
fishing conditions in the North Atlantic?
(7) According to the French scientists at Gif-Sur-Yvette, what do the marine sediment
core samples obtained from the Bay of Biscay(between Spain and France in the South)
indicate about climatic conditions during the past 100,000 years? What observations
have they made in support of this claim?
(8) What do the ice cores from Greenland indicate about the climate change conditions
during the past 20,000 years? What exactly do they use in those ice cores to better
understand the past climatic conditions?
(9) What is the main hypothesis for the cause of significant climatic fluctuations in
Europe during the past 100,000 years based on all these scientific observations and
data?
(10) What is the yearly rate of the retreat of ice sheets on Greenland during the past 10
years? Why is this rate alarming for the scientists?
(11) How are the nations and countries around the world contributing to these dramatic
climatic fluctuations in the North Atlantic? What is the main culprit?
(12) Why is it that scientists cannot forecast accurately future climate conditions, using
their computer simulations? What is their main impediment?
(13) According to Professor Wallace Broecker of Columbia University (NY, USA), what
caused the sudden cooling conditions during the last ice ages? What happened to the
Gulf Stream, according to him?
(14) How do the tropical Gulf Stream waters become very dense in the Arctic Sea,
according to Wallace Broecker, and plunge into the deep ocean, starting the
“Thermohaline Circulation” and the “Global Conveyor Belt”?
(15) Why is it that the North Atlantic sea-water temperatures are increasing on a yearly
basis? Why is this phenomenon important for the ocean circulation patterns? Explain.
(16) Scientists predict that we (the global society) will cross the critical threshold in
climate change in the 2nd half of the 21st Century, resulting in a major collapse (shut
down) of the global conveyor belt system. Give at least 3 significant adverse effects of
this possible shut down.
(17) The 2003 Pentagon Report, entitled “An abrupt climate change scenario and its
implications for US national security”, stated that “….. with continued global climate
change, we would experience by 2010 Siberian winters in northern Europe, increased
water scarcity, mass migrations, chaotic monsoons in China, severe droughts in East
Africa, and an increasingly isolationist foreign policy in the USA focusing on reenforcing its own borders and feeding its own population”. To what extend has this
report shown to be accurate by 2019? Give your specific reasons.
(18) What is the scientific paradox that emerges from this documentary and all the
scientific evidence and observations made during the past 10 years? Be specific.
(19) What do you think the societies and governments must do within the next 10 years
to prevent a catastrophic push in climate change?
(20) This documentary starts with a view and a short discussion of the weather situation
off the coast of Brittany in northern France in the year of 2060, showing severe winter
conditions disrupting many aspects of the daily lives and functions of the people in
Europe. The reporter asks: “Is this a reality OR a fiction?” Based on what you have
learned from this documentary, comment on what you think the answer is. Explain your
reasoning.
