Sentences with phrase «small warming trend»

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).

One passage written by Heartland reads, «Scientists who study the issue say it is impossible to tell if the recent small warming trend is natural, a continuation of the planet's recovery from the more recent «Little Ice Age,» or unnatural, the result of human greenhouse gas emissions.»

Completely independently of this oceanographic data, a simple correlation analysis (Foster and Rahmstorf ERL 2011) showed that the flatter warming trend of the last 10 years was mostly a result of natural variability, namely the recently more frequent appearance of cold La Niña events in the tropical Pacific and a small contribution from decreasing solar activity.

This correction is naturally small (less than a tenth of a degree) and hardly changes the long - term trend of global warming — but if you look deeper into shorter periods of time, it can make a noticeable difference.

The first issue is that because of the large heat capacity of the southern oceans, warming trends are in general going to be smaller than in the northern hemisphere.

So people will fight over small differences, even if everyone accepts a significant warming trend.

bozzza - The differences in the Arctic are perhaps 1/4 the ocean thermal mass as global ocean averages, small overall size (the smallest ocean), being almost surrounded by land (which warms faster), more limited liquid interchanges due to bottlenecking than the Antarctic, and very importantly considerable susceptibility to positive albedo feedbacks; as less summer ice is present given current trends, solar energy absorbed by the Arctic ocean goes up very rapidly.

in southern ontario to show primarily two things: one is that summer temperatures are not increasing, only winter temperatures are increasing therefore it is not in fact getting warmer it is only getting less cold (there is no argument that the seasonally averaged trend is rising); two is that the slight averaged rise is extremely small compared to the daily and seasonal temperature fluctuations.

Teacher input: Because each weather station exists in a unique micro-climate, individual differences cause each station to exhibit small cooling or warming trends that might not be seen at the other stations.

More importantly, we must wonder what the satellites would have observed happening in the Antarctic when Roald Amundsen sailed through the Arctic in 1903 - 1905 on the small wooden ship Gjøa when the Northwest Passage was open to sailing vessels, and again in 1940 - 42 and 1944 (St. Roch), it is possible the reduction in Arctic ice is not an indicator of warming, since it was balanced by record high Antarctic ice levels and a rising trend line for the data set since 1979.

In April, the Met Office released figures up to the end of 2010 — an extremely warm year — which meant it was able to say there had been a statistically significant warming trend after 1997, albeit a very small one.

The CLAs advised against including this statement in the SPM, noting that: the research is currently inconclusive; overestimation of the models is too small to explain the overall effect and not statistically significant; and it is difficult to pinpoint the role of changes in radiative forcing in causing the reduced warming trend, with Co-Chair Stocker referring to this issue as an «emerging science topic.»

Expected global warming trend is mostly beneficial, although the benefits will be small and arrive slowly, just like the temperature changes.

Interpreting these observations further we do have more evidence of global warming by the first observation, but based on the second observation we do have evidence that the longer term trend is likely smaller than many thought based on data up to 2000.

For more information on this topic a good link is: http://www.climateaudit.org/ As these records may not be as reliable as we would want them to be in consideration of the small degree of warming we are trying to measure, it is perhaps better to rely on other measures, which are more accurate, and do show a recent warming trend.

The «unnatural» warming so far seen is however trended strongly to the alterations to the planetary surface by Humanity over the past 400 years and the rebalance towards greater kinetic induction (in its cumulative effect) is now producing observable alterations not only to the Land Surface median Temperature, but to the Ocean (vie conduction / convection) and a still unconfirmed claim of a small overall rise in Median Atmospheric Temperature, which if «true» would place the Planetary Biosphere on the «Human Population Plot» with regard to «warming».

Unlike the continental U.S., with its abundance of micro and regional climates, the small island area of Great Britain affords less climate variety yet produces similar warming / cooling trends over the recent past.

Indeed, a portion of that small linear trend difference might be due to human CO2 emissions; or, then again, it might be due to the vast urbanization effect over the last 60 + years; or due to the large deforestation that's taken place; or, maybe it's entirely due to the serial fabrication of global warming by the world's climate agencies; or it's even possible that the post-1950 warming was entirely a natural phenomenon - the same as the prior 64 - year period experience.

Small wonder, then, that the modelers» computer «reconstructions» of the planet's past climate conveniently wiped out the well - documented three - centuries - long Medieval Warming Period, as well as the subsequent 500 years of Little Ice Age — nor is it surprising that their terrifying computer prognostications in the IPCC's 2001 Third Assessment failed to predict the next decade's absence of any global warming trend Warming Period, as well as the subsequent 500 years of Little Ice Age — nor is it surprising that their terrifying computer prognostications in the IPCC's 2001 Third Assessment failed to predict the next decade's absence of any global warming trend warming trend at all.

So even if they diminish the CO2 effect somewhat, there should still be a remaining warming trend, though small.

I suspect that what Monckton calls «no warming» should actually be «no statistically significant warming», which is a much weaker statement (meaning «there is a small (5 %) probability that such a trend occurs by chance alone»).
