2. The effects on the weather
2.5C increase in temperature
30 cm sea level rise
Damage from flooding
Amount of glaciers melted
2x the number of days above 25C (from 18 to 30 days a year)
10% more rain

3. The Atmosphere
The Earth’s atmosphere is composed of two main gases, nitrogen and oxygen. In fact, 99% of the atmosphere is made from nitrogen and oxygen. The remaining 1% is made from argon, water vapour, carbon dioxide and some trace gases.

4. Note: In the last 150 years, carbon dioxide has increased from 0
Note: In the last 150 years, carbon dioxide has increased from 0.028% to 0.040% concentration in the atmosphere from fossil fuel burning.

5. Atmospheric Layers
Troposphere: The troposphere is the layer of the atmosphere that is the closest to the earth’s surface. It is in this layer is where the Earth’s weather occurs and the majority of the Earth’s cloud’s form. Note that as you move higher in the troposphere, the temperature quickly gets much colder, and can get as cold as -60°C

6. Atmospheric Layers
Stratosphere: The layer above the tropopause is the stratosphere. The stratosphere is very calm and mostly contains ozone. Ozone is a molecule that absorbs the sun’s energy (preventing harmful rays from reaching the Earth’s surface). Since ozone absorbs the sun’s energy, the stratosphere gets warmer than the troposphere.

7. Atmospheric Layers Mesosphere:
This layer is very cold (can get to -80°C), because very little of the sun’s energy is absorbed.

8. Atmospheric Layers
Thermosphere: The thermosphere is a very hot layer. This layer can get hotter than 1000°C, because of the low air density and it absorbs a lot of the sun’s energy.

9. Atmospheric Layers Exosphere:
This is the layer between the Earth’s atmosphere and space. It is between 500 to 10,000 km above the Earth’s surface.

11. What are clouds
Basically clouds are little water particles that come together around a particle The condensation nuclei are particles (such as dust) that were blown up into the atmosphere. If there is enough water in the atmosphere, then the water particles will attach to it, and a cloud will start to form.

12. Humidity
Note: There is constantly water in the Earth’s atmosphere. Humidity is how scientists measure the amount of water in the atmosphere.

13. Different Types of Clouds
Different types of clouds form depending on the humidity and where in the atmosphere the cloud forms.
There are three main types of clouds: low clouds, medium clouds, and high clouds.

14. Low Clouds
These clouds form from warm, moist air. These types of clouds break down into two main categories: cumulus and stratus. Cumulus clouds are puffy and lumpy looking clouds. Stratus clouds look like layers and will cover large parts of the sky. Usually fog is a stratus cloud that drops to the Earth’s surface.

15. Middle Clouds
These clouds from in the middle of the troposphere, around the point where some of the water particles turn to ice particles. These clouds also break down into altocumulus and altostratus. Altocumulus clouds are large and round. Whereas altostratus clouds are gray and form thin sheets. Both types of clouds bring light rain.

16. High Clouds
These clouds are made from ice crystals because they form so far above the Earth’s surface. They break down into two main types: cirrus and cirrostratus. Cirrus clouds are thin and wispy, and cirrostratus clouds act almost like a blanket. They can be very transparent or very dense.
