What are some causes of the anthropogenic greenhouse effect?

Burning fossil fuels, deforestation, agricultural and industrial practices.

Melting sea ice has the potential to raise sea level by several meters. True or False?

False. Melting sea ice cannot raise global sea level since the ice is already floating (think of an ice cube floating in a glass full of water). Ice from glaciers and ice sheets, which form on land, does add water to Earth’s ocean when it melts and contributes to sea level rise.

True or False

Historically, there has been a correlation between carbon dioxide, methane and temperature. 

TRUE

What is albedo?

Albedo is the reflectivity of a surface.

100
An indirect measure.

Which is the primary source of energy in Earths climate system?

The sun.

What percentage of atmospheric carbon is absorbed by the ocean?

30-40%

200

It's released during the drilling of natural gas wells, and through natural processes like in cows and decomposition in flooded rice fields.

Methane
200
70% of the worlds freshwater reserves are here.
Antarctica
200
It has the greatest albedo

Where have some of the strongest and earliest impacts of global warming occurred? In the tropics, in the northern latitudes, or impacts are distributed evenly across the globe.

In the northern latitudes.

Other than melting glaciers and ice sheets, what other factor has made the largest contribution to the rise in sea level over the past 100 years.

Thermal expansion of the ocean. As the ocean warms, it expands and sea level rises, accounting for about a third of the approximately 20cm of sea level rise seen in the last century.

This has multiple sources, including the production and application of nitrogen rich fertilizer and car exhaust.

This would cause sea level to rise 60 meters.

Which of the following gases do not trap heat – carbon dioxide, nitrogen, water vapor, methane?

Nitrogen
400
These are the gases scientists measure when they examine ice cores to determine the historic atmosphere.
Oxygen, methane, and carbon dioxide.
400
When carbon dioxide is lowest in the atmosphere.
Summer
500

Stopped production in the 1980s because they were found to be depleting the ozone layer. 


Chlorofluorocarbons (CFCs)

500

It is an underwater current fueled by the mixing of warm and cold salt water.

Why is carbon dioxide a bigger concern as a greenhouse gas then methane?

Carbon dioxide is released in much greater quantities than methane.

The animal population scientists believe will be reduced by 2/3 by 2050 due to sea ice melting.
