A question for people who believe that humans are causing climate change............?

Question

what about clouds?

Answer 1

What about clouds? What is your' point, or do you not have one?

Answer 2

Huh?

Answer 3

Yeah what's up with them?

Answer 4

You mean the way they block the Solar Rays?

Answer 5

There is a theory that more heat more clouds and that more energy is reflected back into space. But this thought to have a tiny effect.

Answer 6

It is an unknown and important variable when we are considering the effects of climate change.

Answer 7

The clouds contain all the c**p we burn in what ever way,then they dump it all back on us as acid rain

Answer 8

What about them?

Answer 9

what the h**l r u talking abouy freak sorry

Answer 10

strattus alto very pretty. global warming? load of old bolox

Answer 11

What frikking about them?

Answer 12

They are water and has nothing to do with Global Warming.

Answer 13

The overall amount of water vapour in the atmosphere is dependent on atmospheric temperature. Since water vapour is a greenhouse gas, it should increase warming as the atmosphere warms, as a warmer atmosphere can support more WV. It [WV] is therefore not a cause of warming, but a contributing feedback

The principles of the Hydrological cycle are understood pretty well:

Water vapour has a short atmospheric lifetime, around 10 -12 days between evaporation and it condensing and falling as precipitation. The amount of water vapour (WV) the atmosphere can hold is determined by the atmosphere’s temperature, this is known as absolute humidity. (Some of the driest places on earth are high deserts in the middle of Antarctica because of this.)

Heat is energy. If you increase the temperature, you are increasing the average energy of the particles present. That means that more of them are likely to have enough energy to escape (evaporate) from the surface of the liquid.

The First Law of Thermodynamics states that you cannot create or destroy energy.  Energy can change from one form to another, like electricity converting into heat, or heat converting into light, or water converting into vapour. An increase in temperature = increase in available energy.

The stronger the forces that are keeping the molecules together in a liquid or solid state, the more energy that must be input to evaporate them. (It takes about 600 calories of heat energy to change 1 gram of liquid water into a gas form.) Warmer air can also hold more water vapour than colder air because colder air is denser. Heat causes molecules to agitate faster; these cause a parcel of air molecules to expand and so it can hold more vapour.

Therefore water vapour is a feedback, not a cause (forcing) of warming. The absolute (not relative) humidity of the atmos. varies by place, time & altitude, but it’s a stable balance. Add more WV, it won’t stay there, it quickly falls as rain/snow. No effect on temp. But add Co2, CH4 etc and these warm the atmosphere. The air’s capacity to hold vapour (absolute humidity) is limited but increases as the air warms, roughly doubling for each temperature increase of 10°C. CO2 = Forcing. WV + temp = Feedback.

There’s another discussion of the role of water vapour in global warming here. water vapour’s main role is to provide strong positive feedback that increases the effect of global warming.

As for the claimed connection between cosmic rays and cloud formation, even the Danish researchers say they have only detected a 3% difference between solar maximum and minimum periods. The warming and cooling effects of the clouds could even cancel each other out.

Cosmic Rays also create CO2 in the upper atmosphere; they keep quiet about that I notice.

Answer 14

Do you think clouds are causing global warming? all those cloud cars and factory's and stuff, the b"st@rds!

Answer 15

What the Night-Club ........?

Answer 16

What about clouds? That has nothing to do with it.  You wanna know about global warming look at what's happening to the polar ice caps.

Answer 17

clouds????

what do you mean with that?

Answer 18

What about them? Clouds are water vapour that has condensed in colder air. Clouds can alter the albedo of an area by reflecting sunlight back into space but they also reflect IR radiation back towards the planet.

Water vapour is also a greenhouse gas, and as the planet warms up, the amount of water vapour in the air will increase. This has two effects. It can exacerbate the warming effect but the water can fall as rain or snow. Snow also helps to reflect the sunlight back into space.

I can't tell you if this all balances out or if we are in trouble.

Answer 19

yes what about them?

Answer 20

cumulus nimbus floats by

Answer 21

What about clouds?  What shows have you been watching?  I

Dream of Jeannie or Bewitched?

Answer 22

what about clouds? what do you mean?

we are contributing to it, not soley causeing it.

there are things we cant stop, like volcanos, forrest fires and things, but we do build factorys and cars and planes that send out gasses.

Answer 23

Clouds are poorly factored into all climate models.  In fact most don't even consider clouds.

The theory is that as co2 rises water vapor will increase holding in the warmth. The problem with this is that clouds<water vapor> also reflect sunlight back into space reducing warming.  If scientists figure a way to include cloud formation into the models they may find that increased H2O vapor DECREASES temp.

Answer 24

have you been in the pub ?

Answer 25

i am not on the train with people thinking "man" is causing climate change...is all bo***cks if u ask me...but i don't get the cloud thing..is just water vapour ....or not?..

Answer 26

I've always blamed clouds me like.

Answer 27

the change in climate is undeniably our fault.  humans over pollute the atmosphere causing things like the greenhouse effect / global warming to occur.  i'm not quite sure what you mean by the clouds, but the pollution we create also causes acid rain to form in the clouds.

Answer 28

What about clouds? Elaborate.

Answer 29

What aload of c**p. Mother nature is in control not us or U or anyone else. Our climate has been fluctuating since time began and nothing is going to change this.
