Climate Change Practice and Review

Climate change occurs naturally.

It can be magnified by human activities​

What is the difference between climate and weather?

Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time.

the difference is time

Multiple Choice

An example of weather would be .....

• The desert biome supports a limited number of organisms

• The forecast for today is partly cloudy with a small chance of rain

• The rainforest has the greatest biodiveristy

• A tsunami will cause damage during Earth's axis

3 natural causes of climate change.

• Volcanic activity

• Earth's Axis

• Greenhouse Effect

​

Multiple Choice

Which is a natural cause of climate change?

• Fossil fuels

• Carbon

  monoxide

• Deforestation

Volcanic activity

can decrease

overall temperatures

over time​

​

​

​

Emits SO2 (sufur dioxide)

Earth's Axis

can cause extremes in weather

patterns ​

​

​

​

as the tilt increases, weather extremes increase​

Greenhouse Effect and Greenhouse

Gases ​

There are gases that naturally

occur in our atmosphere.

Those greenhouse gases

allow life to flourish on Earth.​

​

​

​

​

​

However, elevated amounts of carbon containing gases can be

detrimental ​

​

Multiple Choice

Greenhouse gases:

• Can be harmful in high amounts in the atmosphere

• occur naturally in our atmosphere

• keep the Earth's surface warm and ideal for life to flourish

• All answers apply

  fossil fuels,

  sulfur dioxide

• deforestation,

  fossil fuels,

  fracking

• volcanic activity,

  earth's axis,

  greenhouse effect

• water vapor,

  mining,

  deforestation

For the last 11,000 years, the southern Pacific Ocean has cycled between warm El Niño and cold La Niña conditions, driving the climate on both sides of the ocean. But new modelling suggests that these cycles may be interrupted as a world warms under human-induced climate change.

EL NINO CAUSES WARM WEATHER AND INCREASED RAINFALL

What is the difference between El Nino and la nina?

​

El Niño events are associated with a warming of the central and eastern tropical Pacific, while La Niña events are the reverse, with a sustained cooling of these same areas.

​

​

These changes in the Pacific Ocean and its overlying atmosphere occur in a cycle known as the El Niño–Southern Oscillation (ENSO). .

​

LA NINA CAUSES COOLER TEMPERATURES AND DECREASED RAINFALL ​

​

A deep pool of cool water is making its' way across the Pacific / La Nina

El Nino temperature patterns brew in the Pacific Ocean

Multiple Choice

Which statement is a true statement as it relates to El Nino?

• El Nino is associated with cooler temperatures

• La Nina is associated with with warmer temperatures

• El Nino is associated with warmer temperatures and increased rainfall

• El Nino is associated with decreased rainfall

El Nino produces warmer air and increased rainfall

La Nina produces cooler than average temperatures and less rainfall

Multiple Choice

Which statement is a true statement as it relates to La Nina?

• El Nina is associated with cooler temperatures and increased rainfall

• La Nina is associated with with cooler temperatures and decreased rainfall

• La Nina is associated with warmer temperatures and increased rainfall

• El Nino cycles back once every year

Can release SO2 (sulfur dioxide)

How do volcanoes effect global climate?

​

​Volcanoes naturally emit sulfur dioxide. The sulfuric acid biproduct produces a haze of tiny droplets in the atmosphere that reflect incoming solar radiation. Causing cooler temperatures. The aerosols can stay in the atmosphere for up to three years, causing significant cooling worldwide.

Multiple Choice

Which statement is true about how volcanic eruptions can effect the global climate?

• volcanic eruptions can cool the Earth's surface

• volcanic eruptions can produce ash that can stay in the atmosphere for years

• volcanic eruptions has only a warming effect on climate

• both a and b

Volcano spews volcanic ash and sulfur dioxide into the atmosphere

The greater Earth's axial tilt, the more extreme our seasons are

​

Earth's axis also effects

climate change ​

As the axial tilt increases, the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres. ... More tilt means more severe seasons—warmer summers and colder winters; less tilt means less severe seasons—cooler summers and milder winters

Earth rotates on a tilt

Multiple Choice

Earth's axis effects the climate in the following ways:

• More tilt means more severe seasons

• The degree of Earth's axial tilt causes all of these effects

• less tilt means less severe seasons

• As the tilt increases, the seasonal contrast increases

Greenhouse gases occur naturally and are part of our atmosphere's makeup. For that reason, Earth is sometimes called the “Goldilocks” planet – its conditions are not too hot and not too cold, but just right to allow life (including us) to flourish.

Greenhouse Gases

Water vapor/H20............2%

carbon dioxide/CO2........... 0.04%

methane/CH4......................... 0.4%

nitrous oxide/N2O ..............0.00003%

​

Some text here about the topic of discussion

Multiple Choice

Which greenhouse gas is the most abundant?

• fluorocarbons

• nitrous

  oxide

• methane

• water vapor

Greenhouse gases' are crucial to keeping our planet at a suitable temperature for life. Without the natural greenhouse effect, the heat emitted by the Earth would simply pass outwards from the Earth's surface into space and the Earth would have an average temperature of about -20°C.

Multiple Choice

Do we need the Greenhouse gases? If so, why?

• Yes, we need greenhouse gases to emit therapeutic levels of CO2 in the atmosphere

• No, we don't need greenhouse gases. Any amount will cause damage to the atmosphere

• No, we do not need greenhouse gases to moderate temperatures on Earth

• Yes, we do need some of the greenhouse gases to keep the Earth's temperature warm

The Glass ceiling

​

Greenhouse gases act like glass ceiling on a greenhouse trapping heat inside. The natural greenhouse gases cover us like a warm blanket

Global warming caused by human activities can

cause an unnatural increase in greenhouse gases ​

​

10 causes of global warming that are contributing to the climate crisis.

1. Oil and Gas. Oil and Gas is used all the time in almost every industry.

2. Deforestation. ...

3. Waste. ...

4. Power Plants. ...

5. Oil Drilling. ...

6. Transport and Vehicles. ...

7. Consumerism. ...

8. Farming. ...

Global warming caused by human activities can

cause an unnatural increase in greenhouse gases ​

Multiple Choice

An example of global warming caused by human activities is

• Copious amounts of methane in the atmosphere from the waste of farm animals and farming practices

• Deforestation

• fossil fuel emissions

• All of these human activities will cause an unnatural occurrence of global warming

Increased CO2 in the atmosphere

Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.

Multiple Choice

What is a major cause of increased CO2 in the atmosphere?

• Deforestation

• Water vapor in the atmosphere

• lava flow from volcanic ash

• hydroelectric power stations

releases fossil fuels in the atmosphere ​

Power Plants

​

​

creates less trees to absorb the excess

Deforestation

​release carbon monoxide into the atmosphere
