«A relatively
small change in the water temperature can destabilise these hydrates fairly quickly.
Deep lakes warm very slowly in the spring, and
small changes in water temperature at the end of winter can lead to large changes in the timing of summer stratification for these lakes.
Not exact matches
Dams, big or
small, have the potential to
change a river's
water flow,
temperature, sediment, and ultimately the patterns
in plant and animal diversity.
At the moment the company is working with NASA to develop technology that would predict how
small - scale, seasonal shifts
in temperature as well as large - scale climate
change influence the presence of bacteria
in the soil, air and
water around crops.
«Even relatively
small changes in the
temperature and
water content of the magma can drastically alter the chemical and physical properties of the unerupted magma,» explained lead author Dr. Mike Cassidy from the Institute of Geosciences at Mainz University.
they claim the tropospheric hot spot exists because more
water vapour should exists
in that region (raising of the upper troposphere), and
small fractional
changes make a larger
change in the
temperature anomaly because GHGs are
in the lower part of the log scale rather that the higher saturated state.
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).
The very
small change in ocean
water temperatures since sea ice measurements began
in 1979 does not match with gains (or losses)
in any season, not from Sept (Arctic sea ice minimum) over through winter to March - April sea ice maximums.
This study therefore suggests the rapid response to CO2 forcing is (apart from a possible
small negative response from LW
water vapour) essentially confined to cloud fraction
changes affecting SW radiation, and further that significant feedbacks with
temperature occur
in all cloud components (including this one), and indeed
in all other classically understood «feedbacks».
It went something like this: hotel check -
in, locate room, locate wifi service, attempt connection to wifi, wonder why the connection is taking so long, try again, locate phone, call front desk, get told «the internet is broken for a while», decide to hot - spot the mobile phone because some emails really needed to be sent, go «la la la» about the roaming costs, locate iron, wonder why iron
temperature dial just spins around and around, swear as iron spews
water instead of steam, find reading glasses, curse middle - aged need for reading glasses, realise iron
temperature dial is indecipherably
in Chinese, decide ironing front of shirt is good enough when wearing jacket, order room service lunch, start shower, realise can't read impossible
small toiletry bottle labels, damply retrieve glasses from near iron and successfully avoid shampooing hair with body lotion,
change (into slightly damp shirt), retrieve glasses from shower, start teleconference, eat lunch, remember to mute phone, meet colleague
in lobby at 1 pm, continue teleconference, get
in taxi, endure 75 stop - start minutes to a inconveniently located client, watch unread emails climb over 150, continue to ignore roaming costs, regret tuna panini lunch choice as taxi warmth, stop - start juddering, jet - lag, guilt about unread emails and traffic fumes combine
in a very unpleasant way, stumble out of over-warm taxi and almost catch hypothermia while trying to locate a very
small client office
in a very large anonymous business park, almost hug client with relief when they appear to escort us the last 50 metres, surprisingly have very positive client meeting (i.e. didn't throw up
in the meeting), almost catch hypothermia again waiting for taxi which despite having two functioning GPS devices can't locate us on a main road, understand why as within 30 seconds we are almost rendered unconscious by the
in - car exhaust fumes, discover that the taxi ride back to the CBD is even slower and more juddering at peak hour (and no, that was not a carbon monoxide induced hallucination), rescheduled the second client from 5 pm to 5.30, to 6 pm and finally 6.30 pm, killed time by drafting this guest blog (possibly carbon monoxide induced), watch unread emails climb higher, exit taxi and inhale relatively fresher air from kamikaze motor scooters, enter office and grumpily work with client until 9 pm, decline client's gracious offer of expensive dinner, noting it is already midnight my time, observe client fail to correctly set office alarm and endure high decibel «warning, warning» sounds that are clearly designed to send security rushing... soon... any second now... develop new form of nausea and headache from piercing, screeching, sounds - like - a-wailing-baby-please-please-make-it-stop-alarm, note the client is relishing the extra (free) time with us and is still talking about work, admire the client's ability to focus under extreme aural pressure, decide the client may be a little too work focussed, realise that I probably am too given I have just finished work at 9 pm... but then remember the 200 unread emails
in my inbox and decide I can resolve that incongruency later (
in a quieter space), become sure that there are only two possibilities — there are no security staff or they are deaf — while my colleague frantically tries to call someone who knows what to do, conclude after three calls that no - one does, and then finally someone finally does and... it stops.
