Well, that “one google seach = a kettle boiling”  seems a bit crazy - kind of government (town council) calculating costs for things like renovating the public toilet (€355.000) in our town here… and yes, they are nuts.
I’m guessing here, but google uses a shitload of energy and of cos this has some effect on the envirment, since their datacentres are located next to rivers or lakes for cooling. How green that is, well I’ve got no idea, neither do I have a proper cite for that - but as I said, it’s a guess.
Almost anything that we as “modern” humans do, produces CO2 - even making a stupid Video about reducing CO2.
 
 
Well, you seem to be more up to date on this, so I shall not mention then how silly it was when you posted that I used more carbon just by searching on Google early. Oops, too late. RealClimate.org  so even all this point of yours was useless .)
The fact is that more research is needed to be certain of the amount ICT is emitting, but ignoring the efficiency that that technology brings to old inefficient technology is silly.
I should post more from the Australian study that found the accusation of Google to be baseless. (And one should notice that the cite you posted does not actually support your point).
There is substantial scope for further research in this area. For a start, this study is confined only
More needs to be more done in computing the carbon footprint of the manufacture of ICT
The carbon emissions caused by the disposal of this equipment at the end of its lifecycle
But the biggest area of potential research is in properly measuring the effect ICT can have as ana small contributor  to the
