Phys273 all the way

[Alexandre Panagiotou @AlexandrePanag1]

haha same! Thank god for #phys273 ;)

[Jordan Cohen @Jordan80142011]

I actually never understood why greenhouse gases were named as such until #Lesson11 #PHYS273

[Alexandre Panagiotou @AlexandrePanag1]

Thank you for the visual support! Very helpful!

[Gary @Gary49146477]

Energy Balance of the Earth. #Phys273 #Lesson11

[Alexandre Panagiotou @AlexandrePanag1]

This is crazy! It will have major negative impacts unfortunately...

[R.Ratt @RamiaRatnasing2]

By the end of the century, scientists expect seas to rise 0.4 to 1.2 meters, depending on how much we humans keep warming the atmosphere. #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

It sadly is...And will most probably continue to warm in the upcoming years

[Sophia @Sophiafr2]

Is the Earth warming? Sadly, yes. #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

This is crazy! It is also very probable that the earth's temperature will continue to rise in the following years. When will all of this stop?

[Jonathan Chung Tit Yin @JC40095776]

The period from 1983 to 2012 was the warmest 30-year period of the last 800 years in the northern hemisphere and likely the warmest 30-year period of the last 1,400 years. #LESSON11 #WarmingEarth

[Alexandre Panagiotou @AlexandrePanag1]

Thank you for the visual support! Helps to understand the concept easily!

[mwhittomePHYS @mwhittome]

What can I say, I just love diagrams that explain systems in easy and comprehensive ways #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

So sad... major actions need to be taken immediately!

[Kevin Uriel Chaia @ChaiaKevin]

Perfect example of the consequences of the increase in global temperature. #Lesson11 #WarmingEarth

[Alexandre Panagiotou @AlexandrePanag1]

This illustration really helps to understand with sector is the most affected by climate change in different parts of the world!

[Jack Drouin @drouin_jack]

I find this a great visual to sum up some of the effects of climate change and the earth warming. #Lesson11

[Alexandre Panagiotou @AlexandrePanag1]

It is important not to confuse the concepts of climate and weather, as they are very different!

[Julia Mae @juliamae57]

The definition of climate is the "typical patterns of weather that occur in a place over a period of years". #Lesson11

[Alexandre Panagiotou @AlexandrePanag1]

Here is a surprising information that I didn't know about the carbon cycle: the amount of carbon is always fixed! The only element that increases is the circulation of the carbon in the atmosphere, principally caused by the combustion of fossil fuels. #phys273 #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

Thankfully, the Greenhouse gazes (H2O and CO2) are there to absorb outgoing infrared radiation and heat up the surface of the earth to about 15 degrees Celsius, instead of -18 if these gazes were not present. #phys273 #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

The Intergovernmental Panel on Climate Change (IPCC) has high confidence that the past 30 years have been the warmest in 800 years! And have a medium confidence that they have been the warmest in 1400 years! This is crazy! Actions need to be taken. #phys273 #lesson11

[Alexandre Panagiotou @AlexandrePanag1]

Carbon monoxyde is colourless, odourless tasteless but still is a poisonous gas! We should really beware of this gas as it has serious impacts on human being's health. #phys273 #lesson10

[Alexandre Panagiotou @AlexandrePanag1]

Nice to see that the total national emissions of Carbon Monoxyde, Sulfur Oxydes, Nitrogen Oxide and Volatile Organic Compounds have reduced in the past years! Lets hope the tendency continues! #phys273 #lesson10

[Alexandre Panagiotou @AlexandrePanag1]

Water pollution has an impact on 5 major areas:
-Agriculture
-Mining
-Urban pollution
-Human waste
-Fatory production
#phys273 #lesson10

[Alexandre Panagiotou @AlexandrePanag1]

Carbone monoxyde is the most important pollutant, accounting for around 50.9% of all pollutants. #phys273 #lesson10

[Alexandre Panagiotou @AlexandrePanag1]

Air pollution has an impact on 4 major areas:
-Human health and wellbeing
-Animal welfare
-Plant life
-Then environment in general
#phys273 #lesson10

[Alexandre Panagiotou @AlexandrePanag1]

Energy saving tool: When buying a new fridge, recycle the old one! Do NOT put it in the garbage or use it at your cottage for example. The old one is likely to use as much as 2 times the energy of the new one #phys273 #lesson9

[Alexandre Panagiotou @AlexandrePanag1]

My next appliances are ENERGY STAR certified for sure! Makes us save a lot of energy.

[Alexandre Panagiotou @AlexandrePanag1]

Thats why the use of the right materials is crucial to increase the insulation of the house!!!

[Just Energy @LCherbaka]

SHOOK ! Typical Home HEAT LOSS: #lesson9 #phys273
1% through basement floor
3% through doors
5% through ceilings
16% through windows
17% through frame walls
20% through basement walls
38% through cracks in walls, windows and doors
