humans are changing Earth’s climate. – Royal Society
This should have the proviso
” by increasing the CO2 concentration in the atmosphere”
and the follow up proviso
” causing the earth to warm more than it would naturally “.
The earth is warming naturally as it comes out of the last ice age.
The cause of why we have ice ages is still not clear despite good theories and is not a concern as we will all be dead many centuries before another and ice ages are not good.
The degree of variation of warmth of the atmosphere, earth surface and sea yearly has only been measured for a short time and quite large variations can occur from year to year.
The amount of variation in temperature the last 40 years is well within the bounds of natural variation [given the large amounts that have been shown to occur in a single year like 1997.] and of no cause for concern and no predictor of future temperatures on a century scale.
As understanding of causes of temperature changes are still in their infancy all we can say is that the earth is expected to get a little warmer overall in the next century and the next millennium.

In regard to CO2, the amount of distorting the facts is incredible. Most people including the Royal Society are aware that CO2 rises have followed the temperature rises not caused them.
This is due to more carbonate substrate dissolving into the warmer sea and the water giving off more of the CO2 it now contains.
In fact in the slight warming that we have had more of the CO2 rise might be just that, a natural response, and the fingerprint? of burning carbon unimportant.
Human CO2 remaining in the atmosphere for thousands of years is also emotive rubbish. How much will remain? after a few years virtually none.
The amount remaining is important, after all each breath we take has a molecule of CO2 breathed out by Julius Caesar [fact] but I am not going to say that he is the cause of CO2 increase /Climate change.
1 molecule in every ton is not important
When the earth cools again a little in the next 5,10 50 years as it will, the CO2 levels will fall.
The earth and sea are a giant buffer system that keeps a balance and the more CO2 we produce the more the earth will absorb.

I hope and trust that the Royal Society is right
humans can change the Earth’s climate. We already do on a micro climate scale. Rivers can be diverted and lakes drained, I live in an area dependent on irrigation.The three Gorges Dam is a monument to human ingenuity. But the big,big stuff is still out of reach.
Heck you have to drop 100 Hiroshima bombs a minute just to keep the planet’s warmth steady. [thanks Gavin].
I cannot see humans doing that for even an hour with all our resources so whatever way it wants to go it is just too big [for the sun] to worry about a few gnats on the surface producing a trace of a trace gas for a micro, micro second.

Trade winds are slower due to global warming Vecchi
Trade winds are faster due to global warming England
now tell me again slowly these are the same?????
Paul S
The only thing which matters with regard consistency between Vecchi 2006 and England 2014 is that the observed trends in equivalent variables during the period of overlap are about the same, which they are.

Are equivalent variables the same thing as gobbledygook?
I am talking about trade winds not equivalent variables of whom knows what and you suggest I am changing the subject.
When you are wrong, dig a deeper hole.

I upset Mosher and am PNG. I would not dare comment on ” you think Mosher believes temperature changes over the past 10-15 years can be entirely explained by CO2 and volcanoes.”
He has written somewhere recently that CO2 and volcanoes may be enough for the last 150 years. He has CO2 is going up , Global air temp should go up and is spot on. My disagreement is that I can see a host of negative feedback factors Including buffering in the sea and perhaps Spencer’s extra clouds that has meant the temperature rise with the CO2 will be negated.
The natural temperature rise in the last 40 years is what has caused the upswell in CO2. Nature will use the excess CO2 to good effect and the CO2 levels will stop rising soon as the earth cools down for the next 40 years with the usual suspects all converting to Ice Age Alarmists instead
