As Dr. Mackey cited in the published article Sea Change: UCI oceanographer studies

The paper he wrote together with Friis - Christensen in which he found a correlation between solar activity and clouds had a «slight» flaw: it ignored that the period of the study coincided with a

ocean surface temperature are going to have an
effect on cloud formation.
«Since the
ocean component of the climate system has by far the
biggest heat capacity», I've been wondering if the cool waters of the deep
ocean could be used to mitigate the

on its own.

On the other hand, if by some chance and what ends up happening is totally independent of human activity, because it turns out after all that CO2 from fossil fuels is magically transparent to infrared and has no effect on ocean pH, unlike regular CO2, say, but coincidentally big pieces of the ice sheets melt and temperature goes up 7 C in the next couple of centuries and weather patterns change and large unprecedented extreme events happen with incerasing frequency, and coincidentally all the reefs and shellfish die and the ocean becomes a rancid puddle, that could be unfortunat

To point out just a couple of things: —
oceans warming slower (or cooling slower) than lands
on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a
bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that
oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside
oceans, so no latent heat) or
oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while
oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this
effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI
effect, but I think the sites are few, and the covered area is very small worldwide, so the global
effect is very poor (but it still can be sensible for regional
effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI
effect (still remembering that it has a small global
effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

Given that, if one wants freedom of choice and an efficient market, shouldn't one accept a market solution (tax / credit or analogous system based
on public costs, applied strategically to minimize paperwork (don't tax residential utility bills — apply upstream instead), applied approximately fairly to both be fair and encourage an efficient market response (don't ignore any significant category, put all sources of the same emission
on equal footing; if cap / trade, allow some exchange between CO2 and CH4, etc, based CO2 (eq); include
ocean acidification, etc.), allowing some approximation to that standard so as to not get very high costs in dealing with small details and also to address the
biggest, most - well understood
effects and sources first (put off dealing with the costs and benifits of sulphate aerosols, etc, until later if necessary — but get at high - latitude black carbon right away)?
