@thatmuslim24434 @HCOC_AhleSunnah there is none. literally got the message from my local masjid which is in Montreal that it has not been sighted.

@SharollC @SharollC One needs to also remember that hydropower is not free from greenhouse gases such as the constructions of dams #Lesson7

[PARDESI_F @PARDESIF1]

@SharollC @SharollC And people say that they will lose their jobs if the coal industry/petrol industry will stop growing and start decreasing b/c of alternatives energy #Lesson8

[PARDESI_F @PARDESIF1]

@SharollC @SharollC True #Lesson8

[PARDESI_F @PARDESIF1]

@SharollC @SharollC It is interesting to see how how many species have been wiped out, yet we do nothing. Imagine if pollution were directly affecting humans, and were killing us with the same vulnerability as the most endangered ones... pollution would be tackled. #Lesson9

[PARDESI_F @PARDESIF1]

@SleimanAlia @SleimanAlia This diagram really helps us show where we can see our energy is lost in any part of our house, and why some places are colder than others #Lesson9

[PARDESI_F @PARDESIF1]

@P999Jake Which is really hard to do so, as spills are something that happens frequently. I think we need to look at different alternatives in order to save the environment #Lesson10

[PARDESI_F @PARDESIF1]

@GursimranKaler3 @GursimranKaler3 YES, now i am curious to see it a map of before and after ,but with a world map. #Lesson10

[PARDESI_F @PARDESIF1]

@HoppOstiguy @HoppOstiguy Me 5 seconds after finishing this lecture... I started lecturing my father about it hahahahahaah. How the tables have turned now @Lesson9

[PARDESI_F @PARDESIF1]

@AfafeAttar @AfafeAttar Yea... plus I am curious now to know how much impact this coronavirus is having for the future regarding the global temperature increase (in terms of CO2 concentration in air) #Lesson11

[PARDESI_F @PARDESIF1]

57% of air pollution can be contributed to transportation #Lesson10

[PARDESI_F @PARDESIF1]

@TaylorHogg5 @TaylorHogg5 And I thought USA probably did have tidal power plants. I think its probably due to having just few sites being economical to produce tidal energy... #Lesson7

[PARDESI_F @PARDESIF1]

@H0Sai @H0Sai I never thought about it, and looking at this, it makes me remember of a car cooling system, a system to help keep the engine not from overheating #Lesson9

[PARDESI_F @PARDESIF1]

@erikfarge1 Now think about what will happen to cities which are below sea levels... We might be seeing famous cities begone under the next 20-60 years. #Lesson11

[erik farge @erikfarge1]

From 1901-2010 the average sea level around the globe rose by .19m! Think about how much water that is #lesson11

[PARDESI_F @PARDESIF1]

@OPhys273 @OPhys273 I know right. Instead of looking for alternatives regarding the climate change, and our impact on the future, we are only caring about what is good for ourselves only. #Lesson12

[PARDESI_F @PARDESIF1]

https://t.co/G63LTBGd42 #Lesson10 Coronavirus is in fact helping pollution go down

[PARDESI_F @PARDESIF1]

@amandam36773910 @amandam36773910 true, even I did not know this before the lecture.

[PARDESI_F @PARDESIF1]

#Lesson12 As long we do not do anything to our annual global CO2 emission, the average global temperature will increase by more than 2 degrees. This shows how badly we are doing right now.

[PARDESI_F @PARDESIF1]

@RachelCutler16 @RachelCutler16 I know right, and I also wanted to know what percentage agriculture has an effect on air... was disappointed a little bit haha #Lesson10

[PARDESI_F @PARDESIF1]

@amandam36773910 @amandam36773910 I know right... plus the amount of animals that have died through these horrendous spills #Lesson9

[PARDESI_F @PARDESIF1]

Did you know it takes 50 years for the average spill of 35,000 tonnes of oil to clear up? #Lesson10

[PARDESI_F @PARDESIF1]

@amandam36773910 @amandam36773910 I always thought the windows were broken or something since I was a kid #Lesson9

[PARDESI_F @PARDESIF1]

16% of the heat loss experienced at a typical home comes through windows ... Is this why I feel cold air coming through some of my windows? or is that just my house ? #Lesson9 #Heating
