Not exact matches

The adjustments are unlikely to significantly affect estimates of century - long trends in global - mean temperatures, as the data before, 1940 and after the mid-1960s are not expected to require further corrections for changes from uninsulated bucket to engine room intake measurements.
You will still SEE an increase in temperatures, but because of the poor localisation the variability is much higher and the effect of small - scale (compared to global) forcings that affect only the region you have measurements for mean that to get the signal from the noise requires more time.
Accordingly, the measurement procedure to obtain the global temperature for e.g. a year requires compensation for the imperfections in the measurement equipment.
If temperature measurements are used unadjusted then there will be no ability to show the required rise in Global Temperature demanded by CAGW.
The large fluctuations in GMST and its sensitivity to natural variability mean that using this measurement to argue that global warming is (or is not) happening requires care.
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).
Unfortunately, establishing the reality of this cloud feedback requires a measurement of global cloudiness with an accuracy of a small fraction of a percent — a very difficult problem.
The adjustments are unlikely to significantly affect estimates of century - long trends in global - mean temperatures, [don't complain, the global warming was there before and after this round of adjustments] as the data before, 1940 and after the mid-1960s are not expected to require further corrections for changes from uninsulated bucket to engine room intake measurements [except by Karl (2015)-RSB-.
This descope and delay were of most concern for applications requiring the 6.9 GHz band, which is of prime importance for measurement of global SST and soil moisture.
A workshop on Long - Term Monitoring of Global Climate Forcings and Feedbacks was held February 3 - 4, 1992, at NASA's Goddard Institute for Space Studies to discuss the measurements required to interpret long - term global temperature changes, to critique the proposed contributions of a series of small satellites (Climsat), and to identify needed complementary monitGlobal Climate Forcings and Feedbacks was held February 3 - 4, 1992, at NASA's Goddard Institute for Space Studies to discuss the measurements required to interpret long - term global temperature changes, to critique the proposed contributions of a series of small satellites (Climsat), and to identify needed complementary monitglobal temperature changes, to critique the proposed contributions of a series of small satellites (Climsat), and to identify needed complementary monitoring.
