Leading: Climate change have been a hot issue over the world by rising temperature and fundamentally changing the word

1. Causes:

Greenhouse effect

Gas from atmosphere: co2, water vapor, methane, nitrous oxide, chlorofluorocarbons -> hit trapped

Burning fossil fuels -> alarming

1. Consequence

Oceans

flooding

Increase sea level

Melting ice sheet: Greenland and Antarctica

Food

Growing crops become more difficult

Plants and animals live shift and water supplies, are diminished

Weather

Rise temperature -> weather: more extreme

Not only storm, flood, … but longer drought

Health

Affect human’s physical health

The amount of smog -> higher temperatures

Some diseases: asthma, heart disease, lung cancer

1. Solution

Human beings: use renewable sources such as solar, wind energy -> don’t produce greenhouse gas emission => able to prevent some worse effects of climate change.

Outline                                                            1. lead-in :                               overpopulation +earth's temperature -> changing our world significantly           2.  Cause                                                       a. Greenhouse effect

Water vapor + carbon dioxide + methane + nitrous oxide + chloro-fluorocarbons -> let the sunlight in + keep heat in

The more greenhouse gasses -> the more heat get trapped => strengthening the greenhouse effect -> increasing temperature                       b. Human activities

The burning of fossil fuels ->  increase the amount of co2 in the atmosphere by more than a third                               c. Reality

The increase in greenhouse gasses has warmed the climate: alarming rate

Earth’s climate hasn’t fluctuated in the past >< the atmospheric carbon dioxide has reached today’s level in 400 of thousands of years.

3. Consequence                                                            a. Oceans

Ice sheets such as Finland, Antarctica are melting

The extra water held once in glaciers causes sea levels to rise + spills out of the oceans.                                                 b. Weather

Make weather more extreme

More intense, major storms, floods and heavy snowfall

Longer and more frequent droughts          c. Food sources

Growing crops becomes more difficult

Plants and animals’ habitat + water supplies are diminished                          d. Health

Creates an environment that traps and increases the amount of smog in urban areas -> asthma, heart disease, and lung cancer

4. Solution

Humans are the ones who can combat it.

Replace fossil fuels with renewable energy sources: solar, wind, etc -> not produce greenhouse gas emissions.

Lead-in: See the efficient human activities from pollution + Figure out solution to overpopulation which drive up the earth’s temperature and change the world around.

1. CAUSES:

The main reason: greenhouse effect

- Gases in the atmosphere: water vapor, co2, nitrous oxide,...  ⇒ keep the heat trapped ⇒ strengthen greenhouse effect + increase the earth’s temperature
- Industrial Revolution: human activities (fossil fuels burning) ⇒ increased co2 by 1/3
2.CONSEQUENCES

Oceans

Ice sheets: Greenland, Antarctica → melting

Extra water → sea levels: rise & spill out of the oceans → flood

Weather

More extreme: storms, floods, heavy snowfall + longer and more frequent droughts

Growing crops → more difficult: plants & animals

Food sources

Agriculture challenges

Health

Trap and increase the amount of smog → health problems: asthma, heart disease, lung cancer

3. SOLUTIONS

Replace fossil fuels with renewable energy sources: solar, wind

=> reduce greenhouse gas emissions

Group 3 (Liên - Lợi - Yến): Causes and Effects of climate change

# data[].attributes.body
1. Lead in
Overpopulation + pollution => increase earth's temperature
2. Causes

Greenhouse effect: CO2, water vapor, methane, NO2…→ heat trapped → increase temperature

Human activities: Burning fossil fuels => increase CO2 => warmer the planet => alarming rate

3. Effects

Ocean: + ice sheet(Greenland + Antarctica): melting => rising sea levels => flooding

Extreme weather : storms, floods, heavy snowfalls, longer and more frequent droughts

Food sources:

+  growing crops: difficult

+  land for plants and animals: shift

+  water supply: diminished.

Health: increased temperature -> smog -> human breathe -> asthma, heart disease, lung cancer….

4. Solutions

Use alternative resources: solar or wind energy.

# data[].attributes.body
1. Intro: Human activities contribute to climate change

2. Causes

The main cause: Greenhouse gasses: water vapor , carbon dioxide, methane , nitrous oxide, chloro-fluorocarbons

Industrial revolution : burning fossil fuels => ↑ the amount of CO2 by more than ⅓

3. Effects

Ocean

Ice sheets in Greenland and Antarctica: melting

Sea levels rise + spilled out of the ocean → flooding coastal regions

Weather: extreme condition: flooding, stome, snow fall, drought

Food source: land lost (animals and plants live shift + water supplies lost), growing agriculture difficulty

Health:  increase the amount of smog → physical health ( asthma, heart diseases, lung cancer)

4. Solutions

Using renewable energy: solar and wind energy.

1. Lead-in

Overpopulation  + earth’s temperature -> changing the world around us significantly

2. Causes

Gases in the atmosphere: water vapor, carbon dioxide, methane, nitrous oxide and chlorofluorocarbons.

> greenhouse gases in the atmosphere => > heat gets trapped + strengthening the greenhouse effect + increasing the earth’s temperature.

Human activities (burning fossil fuels): increase the amount of CO2 by >⅓ since the Industrial Revolution.

The rapid increase in greenhouse gases => alarming rate for a planet.

Atmospheric carbon dioxide has not reached today’s level in hundreds of thousands of years.

3. Consequences

Oceans: Greenland and Antarctica are melting extra water, causing sea levels to rise, and spill out oceans flooding.

Weather: warmer temperatures, major storm, flood, heavy snowfall, drought

Food sources: growing crop difficult, habitat and water supplies are diminished

Health: climate change directly affects human’s physical health. In urban: smog contains ozone causes higher exposure to health problems : lung cancer, heart diseases, asthma.

4. Solutions

Rely on human

Replace fossil fuels with renewable energy sources: solar, wind, etc.

Not produce greenhouse gas emissions

Causes and effects of climate change

Human activities (pollution, overpopulation) →increase the earth’s temperature
1. Causes

Greenhouse effects (main cause)

Gas from atmosphere (water vapor, Co2, No)

Let’s sun in + keep heat from escaping (heat trapped )

→ increasing greenhouse effect→ rise     earth temperature

Human activities: burning fossil fuels→ increase CO2  (> X3 industrial revolution)

==> Warming the planet → Alarming rate

Earth’s climate fluctuated (past)>< high levels (today)

2. Consequences

Ocean: ice melting, sea level rising → flooding

Weather: more extreme, causing storm, heavy snowfall, longer and more frequent drought

Food: difficult growing crops, narrow the areas plants and animals can live, water supplies are diminished

Health : people physical health, higher temperature → expose to higher level of smog → health problems: heart disease, lung cancer, asthma

3. Solutions

Replace fossil fuel by renewable energy: solar, wind.
