Can you provide the answers to these questions?

Question

1. What percentage do humans contribute to ALL greenhouse gases?

2. Assuming that the doubling of CO2 in recent times added about 1 degree, how much warming can we expect if it is doubled again?

3. What are the positive feedbacks?

4. What are the negative feedbacks?

5. Which are more powerful, positive or negative?

6. How much will temperatures increase every time co2 levels are doubled?

Answer 1

1.  A tiny amount.  But that's the part that's responsible for the INCREASE of temperature known as global warming.  Proof below.

Water vapor can't initiate warming because excess water vapor falls out rapidly as precipitation.  Details:

Natural CO2 can't cause warming because it's recycled.  Details:

2.  Your assumption is invalid.  CO2 hasn't doubled (yet).

3.  Many.  The big one is reflective ice melts exposing dark ground.  The scary one is methane release from permafrost.  Certain clouds also.

4.  Few. Certain clouds are about it.

5.  Most all scientists say positive.

6.  2-5 C.  Most likely 3 C.

Answer 2

1 less than 1 percent

2 less than 2 percent

3 warmer temperatures in more areas of the globe

4 none

5 Makes no sense.

6 Very little

The largest producers of "greenhouse" gasses are the rainforrest the oceans.

So do you want to cut down all trees and evaporate the oceans?

Answer 3

your questions are invalid for a number of reasons.

for example, you assume that if we were to stop adding CO2 to the atmosphere, the temp would stop increasing.

that's wrong.

you assume that if you don't get an answer to each of your questions, then the IPCC is not justified in their conclusions and warnings.

that's wrong.

you might note that the average global temp was only 6 degrees lower than it is today, at the depth of the last ice age, 20,000 or so years ago.

doesn't take a lot of change to produce rather dramatic results, it would seem.

you might consider a glass of ice water as an example of how the climate interacts with the polar regions.

for an hour while the ice melts, the temperature of the contents of the glass does not change.

after the ice is completely melted, it's a relatively short time before the contents of the glass is noticeably warmer.

finally, i don't know all of your answers.

just as you don't know all of the answers.

i, however, am not sufficiently conceited that i assume if i don't understand, then it's obviously too difficult for anyone to understand.

have a nice day.

Answer 4

1) Some tiny fraction, but since we're adding new carbon to the system (which has been stored in fossil fuels for millions of years), our contribution is what accumulates in the atmosphere.

2) CO2 hasn't doubled "in recent times".  Doubling of CO2 is projected to increase global temps about 3°C.

3) There are many.  Decreased albedo from ice melt, release of carbon from permafrost, release of carbon from warming oceans, etc. etc.

4) Increased cloudcover is the only one I'm aware of.

5) Positive.

6) It depends.  There is no fixed amount (it's non-linear).

Answer 5

1. Humans contribujte a small amount to greenhouse gases considering all we attribute is CO2. In fact livestock contribute more than us. Did you know that water vapour is a greenhouse gas in fact it is the largest percentage of greenhouse gases at 30 something percent.

2. CO2 Does not influence the heat in any way or form. Right now we are in the middle of a hot patch the sun spots all dissapeared (this is a phenomena that no one has the faintest idea about) and it is now hotter. It is all natural so the CO2 doubling and the heat going up one degree is purely coincidence. Once the sun spots start to accumulate again the earth will get cooler.

3. Tokyo and LA won't be smoggy

4. Tokyo and LA will be smoggy

Yes that is all the CO2 does and even then it isn't the main contributor. It helps to create the smog you see above the biggest cities of the world.

5. Well I guess I would like to be able to see the hollywood sign from more than a kilometre away so the positive.

6. I have already answered this question. The temperature might go up by a degree it might go down by a degree. Who knows.

Answer 6

1 not much but how much has solar output varied between ice ages?

2 if you put a jumper on do you imeadetly become hotter? no it takes a while for you to heat up. its the same with the earth.

3 things that as you increase temp heat up the earth

4 things that as you increase temp cool the earth

5 probably positive, the methane stored in permafrost would be the most powerful.

6 it depends on many factors but if we got to 600-700 ppm it would turn the earth into another planet 6degrees C of change would probably be the lower limit.
