Cloudy climate change: How clouds affect Earth's temperature - Jasper Kirkby

As the Earth’s surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds. Jasper Kirkby details an experiment at CERN that aims to do just that.

Lesson by Jasper Kirkby, animation by Cedric Richer.

The animation was absolutely beautiful!

I don't know about you guys, but I really love these animations :)

If there's so much uncertainty about how exactly and in what quantity aerosols affect global temperatures, WHY is everyone blaming CO2?

[narfolee]

Wow this video is amazing. Finally, a not-too-bias informative video on climate change. Amazing perspective that accounts for the importance of clouds and water vapour. CLOUD research will undoubtedly lead to more answers. Great animation and great information.

Also, to extend what was mentioned in the video, a better understanding of the relative heating and cooling effects of cloud cover would be uncovered by knowing more about formation.  Clouds have a dual role of heating and cooling depending mainly on altitude.  Knowing more about cloud formation in general gives a better understanding on where clouds are forming to know if on in general having more or less cloud has a heating or cooling effect.  

Or to say it say it another way, more clouds could mean more cooling...or less cooling...just depends on the formation factors.

The highest recorded temp on Earth was 134 F in Death Valley on July 13, 1910.
The highest recorded temp in Alaska was 100 F on June 27, 1915.
The highest recorded temp in Hawaii was 100 F on April 27, 1931.
The highest recorded temp in Florida was 108 F on June 29, 1931.
The highest recorded temp in my state, Ohio, was 113 F on July 21, 1934.
These are just few examples of record temps set when CO2 levels were much, much lower.

Quite a few flaws in the argument in this video. 1) Why use 1750 as the base date of comparison when the earth has been warming and cooling intermittently for millions of years?, 2) Why since the 1750 global temperatures have risen 0.8 degrees only? and 3) What about the effect of precipitation from rising sea temperatures on the temperature? As I have read increased precipitation actually leads to high cloud cover which actually reflect more sunlight radiation. 


Please have a read on The Survival of Civilization by John Hamaker as well as To Love And Regenerate the Earth: Further Perspectives on The Survival of Civilization by John Weaver for an alternative theory of global cooling and impending ice age.

The audio in this video was fantastic!

[nyali]

And seven years later we still have the same uncertainty...

[ausriusdidziokas]

At the time of recording the global temperature warmer 0.9 as that year was just over a tenth of a degree cooler than 2015 which just about edged over 1 degrees.

[MARIOFANMAN]

Why is it 1, 5 degrees celsius? You say 1.5 in the video, but i dont see it.

[Hiteshshlaki]

Very informing... I get addicted to Ted for grasping the university concepts.

[mrbigheart]

as alyways, awesome knowledge to be picked from all your videos.. BUT.. the method of delivery is just as important.. so try and normalise the sound of the content and the sound of the intro/outro clips. :)
keep up the good work!

So, it's either going to be a vast change in climate or a cloudy life, 80 years from now?

[westbend]

Shouldn’t more than 2 points in time be used to study clouds formation?

[lcvt]

the universe is and has always been in constant change.

[melonny]

Have scientists ever looked at art works in the 1700's to predict how cloudy it was? That could be a helpful idea.

[operachild]

Why not just look at old photographs/paintings to see how cloudy things *might* have appeared?

[jpdalvi]

While clouds reflect sunlight due to their albedo, absence of clouds and water vapour would make it easier to IR from earth surface radiate much faster back to space. This video has some errors.

[edwardpaterson]

hotter temps=more evaporation= more clouds to reflect the heat of sun rays?
