Atmosphere
How do green house gases work? (How do they trap gases in the atmosphere?
The have a higher resonance due to their chemical composition.
This basically means most is absorbed and re-emitted in all directions by greenhouse gas molecules and clouds.
These regions of the Earth that are experiencing the most dramatic changes due to climate change.
What are the polar regions?
Protecting an environmental space in (relative) isolation
What is conservation?
Doing this can naturally remove carbon dioxide from the atmosphere.
What are planting trees?
This group established the Paris Agreement in 2008
What is the UN?
If the greenhouse effect is natural, then why is today's climate change a bad thing?
Once released into the atmosphere, greenhouse gases remain potent for many years, making it difficult to reverse the process.
How much has CO2 in the atmosphere increased since the Industrial Revolution? In the 10,000 years before the Industrial Revolution in 1751, carbon dioxide levels rose less than 1 percent. Since then, they've risen by:
49 percent or 1.5 trillion tons
The felling and clearing of forested land by humans
What is deforestation?
Oil, coal and gas
What are fossil fuels?
Which country has emitted the most CO2 over time? In other words, which nation has the most responsibility for the greenhouse gases that are currently residing in the atmosphere?
The USA has emitted most to date: more than a quarter of all historical CO2: twice that of China which is the second largest contributor. In contrast, most countries across Africa have been responsible for less than 0.01% of all emissions over the last 266 years
One example of a greenhouse gas
What are methane, water vapor, carbon dioxide, nitrous oxide
How has the global average temperature changed since the Industrial Revolution?
Warmer by more than 1 degree C (2.1 degrees F)
Protecting an environment or space for human use or enjoyment
What is preservation?
Modern instruments have only been around for a little over 100 years. So how do we know what greenhouse gas concentrations (and temperature) were in Earth's past?
Air bubbles trapped in ice cores provide detailed records of what the atmosphere was like in the past.
Examining organisms in marine sediments can tell us what the temperature was like in the past.
Pollen in lake beds shows what plant species have lived there during different times. Different plant populations are associated with different types of climates.
Glacial moraines show when and where previous episodes of glaciers
Tree rings history of drought, fire, and other environmental variations
Which country is emitting the most CO2 presently?
China
What is the greenhouse effect?
Certain gasses in the atmosphere trap heat and warm the Earth
This type of air pollution traps the Sun’s energy in the atmosphere and raises the average global temperature.
What are greenhouse gases?
This is the biggest danger posed by global warming to people living in coastal areas.
What is the rising sea level?
This gas is more than 80x more warming than CO2
What is methane?
Governments suing oil companies or setting emissions rules on car makers is an example of this.
what is structural/organizational action?
What activities are the largest contributors of greenhouse gases?
transportation
What do trees do to support efforts to combat climate change
What is absorb carbon dioxide?
Name an effect on the ecosystem caused from global climate change.
extinction of plants and animals, death of coral systems, wild fires, drought, flooding, storms, ect.
Recycling, car pool, unplug devices/lights, eat less animals, shorter showers, public transportation, are examples of this kind of environmentalism
What is personal?
