@Mohit39134997 I didn't know that!

Do you know a large fraction of species faces increased extinction risk due to climate change during and beyond the 21st century #lesson12

The volcanic eruption of Mt. Pinatubo was in Philippines in 1991 #lesson12

@Jawa95270977 yea this is sad

[Sandy @Sandy00827619]

In 2020: There are clearly observed effects of climate change on: physical systems, biological systems & human systems. #lesson11

@Alexand87517011 I think fusion is better than nuclear fission because fusion reactions produce a lot of amounts of energy, much more than fission reactions and fusion does not produce radioactive, toxic waste products like fission does.

@MudirNatasha True,I also read that China's pollution dropped a lot because of COVID-19.

[Sandy @Sandy00827619]

The natural effects are : solar, volcanic and reflectivity #lesson11

[Sandy @Sandy00827619]

The amount of CO2 in the atmosphere has increased by 30-40% over pre-industrial levels. #lesson11 #phys273

Do you know the definition of Energy Balance is the amount of energy into a system is the same as the amount of energy out the system. #lesson11

[Sandy @Sandy00827619]

Do you know that the period from 1983-2012 was likely the warmest 30 year period of the last 1,400 years? #lesson11 #phys273

[Sandy @Sandy00827619]

Can you describe me the weather and the climate over all this year? Did it change for good or bad? #lesson11

[Sandy @Sandy00827619]

Do you know that the Ozone Layer of the Atmosphere are: Thermosphere, Mesosphere, Stratosphere and troposphere? #lesson10

[Sandy @Sandy00827619]

@MarroCarina Yes, I also think that it's very interesting!

[Sandy @Sandy00827619]

@NPhys273 Oh I will do that next time. Thx for sharing this tip with us!

Do you know that oil pipeline occurrences in Canada (2005-2014): have more occurrences from high pipeline and low vapour pressure than from release of crude oil and condensate #lesson10 #phys273

[Sandy @Sandy00827619]

Emission in Canada: major sources are oil and gas industry and paints and solvents #lesson10 #phys273
