WINTER 2020

[Danica Rossi @Phys273Dan]

Most plant species cannot naturally shift their geographic ranges sufficiently and fast enough to keep up with current and high-projected rates of climate change in most landscapes #phys273 #Lesson12

[Danica Rossi @Phys273Dan]

There are clearly observed effects of climate change on physical systems, biological systems & human systems #phys273 #lesson12

[Danica Rossi @Phys273Dan]

Sadly, as the Earth's surface keeps getting significantly warmer, we are not the only ones affected by it. #phys273

[Lea @Phys273Lea]

Each of the last three decades has been significantly warmer at the Earth’s surface than any preceding decade since 1850 #Lesson11

[Gabriel Rosenbaum @phys273prof]

The final exam will be on Wednesday, April 29 from 9:00-12:00. See the announcement for some more info.

@Phys273Lea Very informative, but also a sad reality! #phys273

[Danica Rossi @Phys273Dan]

Tankless hot water heaters will do hold so many advantages! #phys273

[Lea @Phys273Lea]

Tankless hot water heater have so many advantages! There is no hot water sitting in a tank losing energy, and you don’t run out of hot water since it is heated as you need it! #Lesson9

[Danica Rossi @Phys273Dan]

@GiuseppePhys273 tanned skin and a fully charged phone, couldn't ask for more! #phys273

[Danica Rossi @Phys273Dan]

@SophiaSilla Thanks for the diagram! It's very interesting and explains the process well. #phys273

[Danica Rossi @Phys273Dan]

This is so sad! #phys273

According to the survey done by Food & Water Watch cites that approximately 3.5 billion people in 2025 will face water shortage issues. This will be mainly due to water pollution 😕 #Lesson10 #WaterPollution

[Danica Rossi @Phys273Dan]

CO2 levels are increasing (highest in 400,000 years) and the recent increase in C02 (hence the temperature) is due to human activity! #Phys273 #lesson11

[Danica Rossi @Phys273Dan]

An example of energy balance is if you set your thermostat to a specific temperature, the heater ensures energy balance at that temperature #phys273 #lesson11

[Danica Rossi @Phys273Dan]

The rate that the sea-levels have been rising has been larger than the mean rate during the previous two millennia since the mid-19th century! #phys273 #lesson11

[Danica Rossi @Phys273Dan]

This is so important and you would be surprised by how many households don't have one! #lesson10 #phys273

[Danica Rossi @Phys273Dan]

Easy way to understand the difference! #phys273

[Gary @Gary49146477]

The difference between climate and weather. #Lesson11 #Phys273

[Danica Rossi @Phys273Dan]

In the transformed state NO2 can cause effects on the respiratory system of humans and animals, as well as causing damage to vegetation #phys273 #lesson10

[Danica Rossi @Phys273Dan]

Oil spills have an environmental impact on birds, marine mammals, fish, soil and vegetation #phys273 #lesson10

[Danica Rossi @Phys273Dan]

Most of our serious air pollution is produced either directly or indirectly by the combustion of fuels (transportation and fuel combustion) #phys273 #lesson10

[Danica Rossi @Phys273Dan]

The atmosphere is composed of 78.8% nitrogen, 20.95% oxygen, 0.93% argon and 0.04% carbon dioxide! #lesson10 #phys273

[Danica Rossi @Phys273Dan]

@Nichola93792473 That's what happens when Canadians have to deal with extremely cold winters! #lesson9 #phys273

[Gabriel Rosenbaum @phys273prof]

Starting March 23rd all courses will be delivered in online. The only change for us is that I have opened all of the remaining quizzes as of now and you will have until April 5th to finish them. This is to allow you more flexibility in this uncertain and changing situation.
