Global Warming
1896
When was global warming first identified?
caused by a chemical reaction when chemicals like sulfur dioxide and nitrogen oxides are released into the air.
because it absorbs more carbon than it gives off.
Why is the ocean called a “carbon sink”?
Disrupt food availability
Limit access to food
Affect the quality of the food.
What are 3 ways climate change affects food supply
Used in the 1850s but more widespread use in the 1980s.
When was the term climate change first coined?
Absorbs radiation which heats the atmosphere
What does the ozone layer do?
Sulfuric acid and Nitric acid
What are the 2 specific acids in acid rain?
Around 31%
How much carbon dioxide does the ocean absorb?
a legally binding international treaty on climate change.
Trump took the US out of the agreement and Biden put us back in it.
What is the Paris Agreement? Where did Presidents Trump vs Biden stand on it?
Sea levels have risen 21 cm since 1880. It is expected to rise another 25-30cm by 2050. And the ice sheet is at a “tipping point of irreversible melting” and scientists expect sea levels to rise an unavoidable 1-2 meters.
How much has the sea level risen due to climate change?
The amount of greenhouse gasses that are produced by your actions. EX: driving a car, excessive plane rides. Do more physical activities such as walking somewhere instead of driving, limit the amount of times you fly.
What is a carbon footprint and how can you reduce it?
between 4.2 and 4
On the pH scale how acidic is acid rain?
Phytoplankton and seaweed
Which specific ocean plants help replenish atmospheric oxygen?
Cows account for 14.5% of all global greenhouse gasses.
What does the production of meat and dairy products have to do with Climate change?
corrodes metal and causes paint and stone to deteriorate much more quickly.
How does acid rain specifically affect buildings, statues and gravestones?
created in 1970 to protect the environment
When and why was Earth Day created?
in the more mountainous parts of the US; Such as the smoky mountains.
Where in the U.S. does acid rain precipitate
The southernmost reefs in Florida
Which coral reefs in the U.S. are affected by ocean acidification?
Intensity and frequency of hurricanes have been increasing since the early 1980s and they are going to continue to get more intense and frequent.
How have the number of hurricanes changed over the past century?
Legislation such as the clean air act have been passed
What has the U.S. done to curtail acid rain in the past few decades?
Chemicals that have carbon, chlorine, and fluorine atoms. Used in aerosol sprays and refrigerants. They damage the ozone layer which allows harmful uv rays to enter the atmosphere.
What are CFCs?
Industrialized areas and factories.
Where in the U.S. are the gasses that produce acid rain emitted from?
Mussels and other mollusks and organisms that use the minerals for their shells.
Which specific marine life organisms are affected by this acidification?
Respiratory and heart diseases.
Lyme disease and West Nile Virus (pest related)
Water and food related illnesses
What are 3 significant health issues related to climate change?
Carbon dioxide and methane.
What are the 2 main gasses contributing to global warming?
