It's also good to keep in mind that CO2 is beneficial; more CO2 is better; any small

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).

warmer, lake ice in North America is thawing sooner (where it happens in northern states and Canada), most glaciers are shrinking, early spring snowpacks

assuming what you say about skeptics changing topic as you describe is accurate, and at this point I do we are talking about data that is less than 200 years old,

prediction of no snow re-branded as more snow a
warming world re-branded to a «
warm, cold, we don't know what to expect» world topped off with suggestions that one who thinks the above has some sort of psychological disorder extraordinary claims demand extraordinary evidence especially when you are teaching children that their world is endangered
So, although I have a lot of respect for Hansen, who has the track - record of saying things that seem a bit far -
out at the time but later become quite well - accepted by the scientific community (such as when he pronounced back in the late 1980s that the
warming occurring was almost definitely due to greenhouse gases), I think it is at best premature to give much credence to this particular
prediction of Hansen's.
