a. China
Which statement about sunspots is NOT true? (based on short movie and Global Warming Graphs PowerPoint) a) Sunspots show a good correlation to global warming, and that has been very true for the last 30 years b)The U.S. Navy and NASA have concluded that recent sunspot activity over the past 30 years would contribute a slight cooling to the climate c) Increased sunspot activity would increase the temperature in the stratosphere, but that has not been the case in recent years as the stratosphere has cooled down, even while the lower troposphere has heated up d) Sunspots are a natural event that has influenced the earth's climate in the past, but cannot be responsible for the recent warming according to the vast majority of climate scientists
a. Sunspots show a good correlation to global warming, and that has been very true for the last 30 years
Which of the following is an indicator that the warming taking place in recent years must be a result of human emissions and increased levels of greenhouse gases, rather than natural drivers? a) The upper-level stratosphere is cooling but the lower troposphere is warming b) The angle of the earth has changed from 23.5 to 24.5 degrees c.)There is more sunspot activity on the surface of the sun than ever before d) The amount of cosmic rays coming into the atmosphere from the sun has gone up
a. The upper level stratosphere is cooling but the lower troposphere is warming
Temperature and CO2 levels always correlate together, but CO2 ALWAYS goes up first and temperature follows (CO2 is always the cause)
false
Which of the following statements regarding climate change is TRUE? a) El Nino and Sunspots have been identified by most scientists as the drivers of the Ice Age b) Clouds can act as a negative or positive feedback to global warming, but recent research seems to show the positive feedback is more important c) Temperature and CO2 levels always correlate together, but CO2 ALWAYS goes up first and temperature follows (CO2 is always the cause) d) Temperature and CO2 levels always correlate together, but Temperature ALWAYS goes up first and CO2 follows (Temperature is always the cause)
b. Clouds can act as a negative or positive feedback to global warming, but recent research seems to show the positive feedback is more important
Which of the following will experience the greatest negative impacts from climate change? a.) Fossil fuel companies b.) Poor nations in Africa and Asia, and small island nations in the Pacific c.) Industrialized nations like the United States, Japan, and Europe d.) Large coastal cities in wealthy nations like New York City and London.
b. Poor nations in Africa and Asia, and small island nations in the Pacific
Which of the following countries emits the greatest amount of CO2 PER CAPITA into the atmosphere? a.) China b.) United States c.) Australia d.) India
c. Australia
Which of the following is NOT one of the Milankovitch cycles that has been cited as a major cause of the Ice Ages (and interglacial warm periods)? a) The tilt of the earth's orbit varying b) The shape or elongation of the earth's orbit around the sun c) The thickness of the earth's atmosphere d) The wobble of the earth as it rotates on its axis and orbits the sun
c. The thickness of the earth's atmosphere
Which country is MOST vulnerable to the negative impacts from sea level rise? a.) United Kingdom b.) Netherlands c.) Peru d.) Bangladesh
d. Bangladesh
Which of the following is NOT another negative impact associated with climate change and oceans? a.) Sea level rise in coastal areas b) Ocean acidification c.) Destruction of coral reefs and loss of fish spawning areas d.) Loss of Arctic sea ice for transportation lanes
d. Loss of Arctic sea ice for transportation lanes
What time scale doe tectonic changes in the earth's plate movements exist on? a) 1 to 3 years b) Hundreds of years c) 100,000 years d) Millions of years
d. Millions of years
According to the short 1 minute British movie ("Teddy") on trend versus variation which of the following global warming myths is debunked? a)Scientists were predicting global cooling in the 1970s b) Thousands of scientists signed a petition denying global warming c) The temperature always goes up first, so it is not the result of CO2 emission, but rather the cause of any changes d) The earth is now cooling as can be seen when we examine the data from 1998 to 2005, because 7 years is enough data to identify a trend.
d. The earth is now cooling as can be seen when we examine the data from 1998 to 2005, because 7 years is enough data to identify a trend.
A positive Feedback is a good thing for climate change in that it will deter any changes and force the system back to the original state.
false
El Nino and Sunspots have been identified by most scientists as the drivers of the Ice Age
false
High clouds act as a negative feedback for climate change.
false
Most military leaders and insurance professionals see efforts to mitigate climate change as threats to their ability to defend the nation, and keep their business thriving.
false
Sunspots show a good correlation to global warming, and that has been very true for the last 30 years b)The U.S. Navy and NASA have concluded that recent sunspot activity over the past 30 years would contribute a slight cooling to the climate
false
CO2 levels in the atmosphere are the highest they have been in 400,000 years, and these CO2 levels have never been above 1950 levels (315 ppm) during that period except for the last few years.
true
Clouds can act as a negative or positive feedback to global warming, but recent research seems to show the positive feedback is more important
true
Even during years of strong natural cooling drivers, like the eruption of Mt. Pinatubo in the Philippines in 1991 and a strong La Nina in 2010, the average global temperature was higher than the 20th century average.
true
Increased sunspot activity would increase the temperature in the stratosphere, but that has not been the case in recent years as the stratosphere has cooled down, even while the lower troposphere has heated up
true
Sunspots are a natural event that has influenced the earth's climate in the past, but cannot be responsible for the recent warming according to the vast majority of climate scientists
true
Tectonic changes (the rock cycle) are a negative feedback for earth's climate.
true
The U.S. Navy and NASA have concluded that recent sunspot activity over the past 30 years would contribute a slight cooling to the climate
true
The natural climate driver known as EL Nino can affect global warming, but it operates over a few-year time scale, and cannot be responsible for the warming of the last 4 years.
true
The oceans are warming faster than the atmosphere
