I cannot believe the amount of convoluted garbage.
Blind freddy can tell you that with increased heat we are, and we have, increased cloud. This in turn cools things down.
But it will only temper things for awhile.
Forget the conjuxtamongalationtedness of the science,tists, just look around, judge and think for yourselves.

Here's my theory on it and it comes down to coal. Not CO2, but coal as such.
In developed countries coal is really only used in 3 situations. Power stations (by far the largest use), steel works (second largest) and large factories (things like cement works, smelters etc).
A key point there is that these facilities, with very few exceptions these days, have electrostatic precipitators and/or fabric filters to remove 99%+ of particles that would otherwise go up the stack. In most cases there are also fairly strict limits on sulphur dioxide (SO2) emissions - either they are using coal with a low sulphur content (generally the case in Australia) or have equipment to remove the sulphur on site.
In developed countries there is very little use of coal for heating homes etc. And what little is used, is in most cases either naturally rather clean (anthracite coal) or is a manufactured "smokeless" fuel.
Coal use in developed countries hasn't changed a lot over the past 15 or so years. A bit of growth here, a bit of decline there, but no huge change overall. Meanwhile global coal use has risen 65% since the year 2000 with China alone accounting for around 70% of that increase. India accounts for 8% of the increase. All other countries combined account for the remaining 22% of the rise.
But a look at air quality in China reveals that quite obviously they don't have the same level of particulate and SO2 control on coal combustion that we have in Australia (for example). Indeed they use coal not only a power stations etc where such controls are practical (but not always fitted) but also at millions of smaller facilities (including individual homes) where pollution controls are completely impractical to implement. Hence the "brown cloud" of smog.
Go back to 2000 and the accepted explanation for global temperatures not rising between about 1950 and 1975 related to "dirt" going into the atmpsphere and in particular sulphur which reflects sunlight.
Well guess what? The earth appears to have again stopped warming at the same time as a huge rise in coal use in China and the associated emission of SO2 and particles.
In the long term CO2 may well increase temperature. But SO2 and particles have a much shorter life in the atmosphere, such that it current activity directly determines their concentration (ie stop burning coal tomorrow and the levels of SO2 and particles will fall a lot faster than CO2 would). The short term effect of coal use with minimal pollution controls is thus to reduce temperature until such time as the increasing CO2 offsets the effect of SO2 and particles.
I'm not putting this forward a proven theory. It's just my own thoughts although it is based on past research of others regarding SO2 and other visible ("smoke") pollution and the effect it has of reflecting sunlight.
Note that my comments about China aren't intended to be in any way racist etc. I'd be saying the exact same thing if it were Australia, the US, UK or anywhere else that had the same set of circumstances. But nobody would deny that China is burning a huge amount of coal now, and that the amount used has greatly increased in recent years. And the Chinese themselves are all too aware of air pollution issues caused by it.
Coal production figures for China and (rest of world excluding China) as follows. Figures are billions of tonnes.
1999 = 1.46 (3.57)
2000 = 1.51 (3.63)
2001 = 1.63 (3.76)
2002 = 1.72 (3.72)
2003 = 1.95 (3.81)
2004 = 2.13 (3.93)
2005 = 2.48 (4.06)
2006 = 2.65 (4.23)
2007 = 2.84 (4.31)
2008 = 3.02 (4.39)
2009 = 3.30 (4.36)
2010 = 3.51 (4.44)
2011 = 3.84 (4.62)
... 'I love the smell of coal dust in the morning'
...He [George Brandis] isn’t a climate-change denier… But he has nonetheless found himself ‘really shocked by the sheer authoritarianism of those who would have excluded from the debate the point of view of people who were climate-change deniers’....
He describes how Penny Wong ... would ‘stand up in the Senate and say “The science is settled”. In other words, “I am not even going to engage in a debate with you”.
It was ignorant, it was medieval, the approach of these true believers in climate change.’ .... And to Brandis, this speaks to a new and illiberal climate of anti-intellectualism, to the emergence of ‘a habit of mind and mode of discourse which would deny the legitimacy of an alternative point of view, where rather than winning the argument [they] exclude their antagonists from the argument’…

Logique, What you are saying is the way communism works.....suppress all opposition...control
the media.
Well writ, sir!... it's not hard to see why the issue has slipped down the agenda.
I think blind freddy is changing the story ad hoc.
denying folk like me....
You know plod, you have no honour nor dignity.

Picking the man is not productive to debate on such an important issue.
Back to climate change and CO2, I used to think that we could solve this but my view changed about a decade ago and here's why.
Energy use is fundamentally linked to real (as distinct from financial transactions etc) GDP. And the world is still very much trying to achieve constant growth despite this being a finite planet. So long as that continues, we'll keep going "business as usual" until some serious event occurs to bring about change. By then it will be too late.
