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).

Mean sea level (MSL) evolution has a direct impact on coastal areas and is a crucial index of climate
change since it reflects both the amount of heat added in the ocean and the mass loss due to
land ice melt (e.g. IPCC, 2013; Dieng et al., 2017) Long - term and inter-annual variations of the sea level are observed at global and

regional models can generate very different
land - use
change scenarios from those generated by IAMs (Busch, 2006), often with opposing directions of
change.
However, the need to define outside influences on
land use in
regional - scale models, such as global trade, remains a challenge (e.g., Sands and Edmonds, 2005; Alcamo et al., 2006b), so IAMs have an important role to play in characterising the global boundary conditions for
regional land - use

Modeled
regional and global climate responses to simulated (107, 110, 111) and reconstructed historical
land cover
changes over the past century (112) and millennium (113) generally agree that anthropogenic deforestation drives biogeophysical cooling at higher latitudes and warming in low latitudes and suggest that biogeochemical impacts tend to exceed biogeophysical effects (113).
Vegetation cover
changes caused by
land use can alter
regional and global climate through both biogeochemical (emissions of greenhouse gases and aerosols) and biogeophysical (albedo, evapotranspiration, and surface roughness) feedbacks with the atmosphere, with reverse effects following
land abandonment, reforestation, and other vegetation recoveries (107).
The coupling between
land surface vegetation and atmosphere could also potentially cause abrupt
changes of atmospheric circulation at
regional scales.
For example, Chase et al. (2000a) found that
regional land - use
change can cause significant climate effects in other regions through teleconnections, even with a near - zero

To have the ability to constrain future climate projections, they would ideally have strong connections with one or several aspects of climate

regional patterns or transient aspects of climate
change.
