@michaelaPHYS273 Hot like u

[Slaviana Iordanova @SlaviPhys273]

The oil that we heat with the Sun's energy can reach up to 400 degrees Celsius! That is really really hot. #Phys273 #Lesson6

[Slaviana Iordanova @SlaviPhys273]

@XIYANG29654347 It definitely already has some positive impacts on the environment. Have you seen how clear the canals in Italy are at the moment?

[Slaviana Iordanova @SlaviPhys273]

@PatrickMallet13 @jennciccarello Yes, that is also true.

[Slaviana Iordanova @SlaviPhys273]

@SophiaSilla @jennciccarello Exactly. It really is a wake up call.

[Slaviana Iordanova @SlaviPhys273]

@syed_tahzib Exactly! Instead of making everything about money and consumption, we should make everything about our planet's health!

[Slaviana Iordanova @SlaviPhys273]

@Sthinel1 We definitely would need to cut out at least 50% of these emissions to keep it at 2 degrees!

[Slaviana Iordanova @SlaviPhys273]

@sultandeeb7 That is crazy! So efficient.

[Slaviana Iordanova @SlaviPhys273]

Climate change not only amplifies old risks but it also creates new ones. This is applicable in countries of all levels of development. Usually when people think about climate change, they simply envision the current situation to get worse. #Phys273 #Lesson12

[Slaviana Iordanova @SlaviPhys273]

Climate change is a lot more serious than some people might think and more people should get informed about its impacts on the wellbeing of our planet. #Phys273 #Lesson12

[Slaviana Iordanova @SlaviPhys273]

The relationship between cumulative CO2 emissions and projected global temperature is linear. #Phys273 #Lesson12

[Slaviana Iordanova @SlaviPhys273]

@YihanWa11065302 Ignorance is literally killing our planet at this point.

[Slaviana Iordanova @SlaviPhys273]

Knowing that "baseline" means continuing on the path we are on, I do not think that we are going to follow a baseline. The world is consuming and producing more and more every day... #Phys273 #Lesson12

[Slaviana Iordanova @SlaviPhys273]

@jennciccarello So sad to see animals die from it :(

[Slaviana Iordanova @SlaviPhys273]

@EstaitieOmar I wish solar energy was not so expensive! Could be used by so many more people.

[Slaviana Iordanova @SlaviPhys273]

@Joud07339627 I know right! And the fact that most heat loss is from cracks...

[Slaviana Iordanova @SlaviPhys273]

@SharollC Yes, definitely useful info!

[Slaviana Iordanova @SlaviPhys273]

The energy flow for hydropower is:
Electromagnetic energy from the Sun --> thermal --> gravitational potential energy --> kinetic --> electrical. #Phys273 #Lesson7

[Slaviana Iordanova @SlaviPhys273]

It is very interesting that we have developed a way to create climate models. These can be very useful. #Phys273 #Lesson12

[Slaviana Iordanova @SlaviPhys273]

CO2 concentrations have increased by 30-40% over pre-industrial levels. Knowing that CO2 has direct effect on temperature, we are directly affecting the temperature on Earth... #Phys273 #Lesson11

[Slaviana Iordanova @SlaviPhys273]

CO2 and temperature are highly correlated. They affect each other and this is driven mostly by astronomical effects, so it is a natural process. #Phys273 #Lesson11
