According to our #lesson12 lecture, rural areas are expected to experience major impacts on:

- water availability and supply
-food security
-infrastructure
-agricultural incomes

[APhys273 @a_phys273]

scary to think that a global temperature increase of ~4 degrees or more, combined with increasing food demand, could pose serious risks to food security globally :/ #lesson12 #impacts

[APhys273 @a_phys273]

3 steps to climate models:

1- Planet is divided into grid of squares
2- Each square is layered into tiles (each tile represents a precise land, ocean, etc)
3- Climate data for a specific tile are fed into a computer

greenhouse gases: gases that are transparent to visible light but not transparent to IR #lesson11

[APhys273 @a_phys273]

crazy to think that the warmest 30-year period of the last 800 years in the Northern Hemisphere was from 1983 to 2012.. #lesson11 #climate

[APhys273 @a_phys273]

So cool to learn about the difference between climate and weather in #lesson11! #climate #weather

@Jacquel35988990 I haven't but I'd love to someday!!

[APhys273 @a_phys273]

@Alexand87517011 agreed! we need to all start making more of an effort to reduce pollution

[APhys273 @a_phys273]

so sad to think about their homes being destroyed due to oil spills :(

[Danica Rossi @Phys273Dan]

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

[APhys273 @a_phys273]

@VanessaSciangu1 definitely!!

[APhys273 @a_phys273]

Major contributors to..
Carbon Monoxide: transportation
Sulfur Oxides: ore and mineral industries
Nitrogen Oxides: Transportation

[APhys273 @a_phys273]

Lesson 10 taught me that there are two different types of air pollutants: primary and secondary #lesson10 #pollution

@amandam36773910 @PARDESIF1 same here, our lectures are always so informative #lesson9

[APhys273 @a_phys273]

@PiccoloKiara will definitely be looking out for energy star certification when it comes time for me to start refrigerator shopping!!

[APhys273 @a_phys273]

The lecture on appliances and lighting gave many helpful tips on better use of our fridges, dyers, dishwashers, etc! #lesson9 #energyconservation

[APhys273 @a_phys273]

always good to have pictures like this to help solidify our understanding of the concepts, thanks for posting this! #lesson9 #energyconservation

[APhys273 @a_phys273]

good for you for taking the initiative! we should all do the same #lesson9 #energyconservation

[Alexander L. @Alexand87517011]

In order to save energy, I will make sure to spin my clothes as long as I can to remove as much moisture as possible before throwing my clothes in the washer.
How will you save energy? #Lesson9 #EnergyConservation

[APhys273 @a_phys273]

Thanks for sharing this! allows for a clear differentiation between nuclear fission and fusion

[APhys273 @a_phys273]

@bensmihen didn't know this either! learning a lot this lesson

[APhys273 @a_phys273]

learnt in lesson 9 that 63% of our household energy use is from space heating #lesson9 #energyconservation
