The likelihood of which extreme weather event is expected to increase with climate change?
droughts
all of these
heat waves
hurricanes
Which nation has the most responsibility for the greenhouse gases that are currently residing in the atmosphere?
China
USA
Russia
India
When was the last time in Earth's history that CO2 was as high as it is now?
This is the highest it's ever been
CO2 was at least this high during the warm periods between the ice ages
CO2 has not been this high for almost one million years.
The last time CO2 was this high was 3 million years ago.
How has the global average temperature changed since the Industrial Revolution?
Cooler by 0.1 degree C (0.2 degree F)
Warmer by more than 1 degree C (2.1 degrees F)
The temperature has gone up and down, but remains overall the same
Warmer by almost 2 degrees C (3.6 degrees F)
Which activity is the largest contributor of greenhouse gases?
Deforestation
Agriculture
Transportation
Industry
If the greenhouse effect is natural, then why is today's climate change a bad thing?
Humans have altered a natural process and exaggerated changes that might normally occur over millions of years.
A small increase in greenhouse gas concentration can have a large effect of increased warming.
Once released into the atmosphere, greenhouse gases remain potent for many years, making it difficult to reverse the process.
All of these
What proportion of climate scientists has concluded that humans are the primary driver of today's climate warming?
33%
55%
46%
97% or more
How long does CO2 remain in the atmosphere?
CO2 washes out of the atmosphere seasonally.
CO2 remains in the atmosphere for 5-10 years.
CO2 remains in the atmosphere for up to 200 years, or more.
CO2 remains in the atmosphere for up to 100 years
If we stopped burning fossil fuels today, what would happen to the climate?
Earth's average temperature would continue to rise.
Temperatures would continue to warm, then begin to cool down in 100 years or more.
Temperatures would fluctuate, but stay the same on average.
Temperatures would stop increasing once greenhouse gas concentrations stopped increasing.
What is the primary cause of the overall rising trend in CO2 in the atmosphere?
The increase in CO2 is caused by burning of fossil fuels
CO2 is increasing because we are coming out of an ice age
As human population grows, people exhale more CO2
CO2 is released by the oceans as they warm
What are the major causes of sea level rise?
Seawater expanding as it gets warmer
Rivers accelerating
Rocks and soil washing into the sea
Melting glaciers and ice sheets
What causes ocean acidification?
CO2 dissolved in ocean water
Sunscreen in the water
Sediment stirred up by extreme storms
Ocean pollution
How fast to we need to stop burning fossil fuels to limit global temperature rise to 2 degrees C? (3.6 degrees F)
We need to stop burning fossil fuels by 2100.
We need to stop burning fossil fuels by 2040.
Fossil fuels don't matter, the Sun will cool and so will the Earth.
We need to stop burning fossil fuels by 2060.
Which is not a possible effect of global warming?
Lowered sea levels
Raised sea levels
More extreme weather
Melting ice sheets
What percentage of the earth’s atmosphere is comprised of carbon dioxide, the greenhouse gas?
0.04
1.04
19.04
40.04
Which five-year period was the warmest on record?
2001-2005
2006-2010
2011-2015
2016-2020
