@ElenaLuvsEnergy @ElenaLuvsEnergy, we are getting closer and closer though! it is a matter of time! maybe this will "fix" all that we broke! #Phys273

@Wendyrodelo3 @KpPhys273 @Wendyrodelo3, as it has been said, I agree! We are a small drop in the ocean, but just like GHG amplifies Global heating, each of our voices and actions do too! #Phys273

[Gary-James Johnston @GaryJamesJohns2]

@GALBINO7 @GALBINO7, is it because it has air holes within it? What makes it float? #Phys273

[Gary-James Johnston @GaryJamesJohns2]

@BrookePhys273 @BrookePhys273, very good fact! The implication on life all around! Are huge! #Phys273

[Gary-James Johnston @GaryJamesJohns2]

@LauriePierDube2 @LauriePierDube2, me either! Guess that is why Mountains get in the way of radio waves! There is less ...space between them and the thermosphere #Phys273

@PBERTONE3 @PBERTONE3, interesting, if we slowly stopped exporting coal, would we be able to phase it out? Or would they simply buy it from someone else? #Phys273

@CadieuxCoralie @CadieuxCoralie, Let me try this, lets say you put clothes in a dryer, all nicely folded (ordered) and then you start the dryer. All your clothes will unfold and become disordered .. the chances of them folding themselves again is near zero. #Lesson3

@VivianDeng13 @VivianDeng13, I wonder if they will ever create a technology that can reverse it and take it out of the atmosphere? #Lesson11

[Gary-James Johnston @GaryJamesJohns2]

We have seen that Climate Models are accurate with the Volcanic eruption of Mt. Pinatubo in 1991. This is not fake news but fact! Wake up! The point of no return is soon upon us! #lesson12

[Gary-James Johnston @GaryJamesJohns2]

Green Gas Effect; I think the problem is that people do not understand this easy concept, a plus 2 degree increase can really mean a plus 12 degrees global average! It is huge! #Lesson12

[Gary-James Johnston @GaryJamesJohns2]

Extinction: Most plants won't be able to adapt fast enough to survive the increase in Temperature... I am sure we cannot even understand what impact this will have on Earth! #Lesson12

[Gary-James Johnston @GaryJamesJohns2]

The Climate Change risks are huge if we continue on our path! The world as we know it will not be the same world our kids and grand-kids will know! #Lesson12 #ClimatePredictions #Impacts

[Gary-James Johnston @GaryJamesJohns2]

Stabilization wedges: we have increased building efficiency. We covered this in the beginning of class! This can be covered by bylaws and construction codes. #Lesson12

[Gary-James Johnston @GaryJamesJohns2]

@DjaoutMounia, I will not guess your age, but Energy Star has been around for a while and is very much worth it! #Lesson9

[Gary-James Johnston @GaryJamesJohns2]

@SaraLovesEnergy, it would seem like the human mind can only interpret one thing at a time! Especially if that thing doesn't affect them directly, they can ignore it completely! Change has to come! #Lesson12

[Sara @SaraLovesEnergy]

Animal extinction feels like old news, but it can keep going past the 21st century if we don't change our ways!

#Lesson12 #PHYS273

[Gary-James Johnston @GaryJamesJohns2]

@DjaoutMounia, the evidence is overwhelming! Yet, some believe it to not be true! I love the YES!! #Lesson11

[Gary-James Johnston @GaryJamesJohns2]

@VivianDeng13, you have to admit this is pretty amazing! But ... what about the regions that do not have ice? Does this have an impact on the end numbers? #Lesson11

[Vivian Deng @VivianDeng13]

Interesting that you can find out about the Earth's temperature using ice core. #lesson11

[Gary-James Johnston @GaryJamesJohns2]

@jennciccarello, I couldn't agree more! #lesson12

[Gary-James Johnston @GaryJamesJohns2]

@jennciccarello, I totally agree! I want my nephews to look at the course once I am done! I think this course is so well made that even they would understand! #lesson12

[Gary-James Johnston @GaryJamesJohns2]

@MabelChang14, I know, right! And natural, it has been occurring forever and we just think it is bad.. it is in a way because of us, but still just normal! #lesson11

[Mabel @MabelChang14]

din’t know that greenhouse effect was part of the earth’s energy flow! #lesson11
