«The change of phase from snow and ice to water is the biggest tipping point in the Earth's system and so, although International Polar Year covers a huge range of science, for me the big issue is climate change and the impact that it's having here,» said Chris Rapley, director of the British Antarctic Survey, in a video message from Antarctica.

The only things that can change that resultant point of temperature equilibrium significantly are changes in solar radiance coming in and changes in overall atmospheric density (a function of mass and pressure) which affect the radiant energy going out or a change in the speed of the water cycle which, because of the unique characteristics of the phase changes of water altering the speed of energy flow through the system is capable of exerting a powerful regulatory effect.

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).

comment on Arno Arrak 8:26 am in truths n ° 2 and n ° 5 the main point is that a periodic waveform should not be approximated by a straight line, and that one should at least try a sum of sinusoid with as little free parameters as possible (in this case only the amplitude and phase of the 210 and 60 years sinusoids, as the Hadcrut series is too short for a Fourier or wavelet decomposition see as well the paper of Macias reference 18); the figure 15 - A shows the step wise changes of the temperature paced by the El Nino events: this has been shown in detail by Bob Tisdale.

In discussions of global change, the term tipping point has been used to describe a variety of phenomena, including the appearance of a positive feedback, reversible phase transitions, phase transitions with hysteresis effects, and bifurcations where the transition is smooth but the future path of the system depends on the noise at a critical point.
