Sentences with phrase «measure ocean warming»

Karl's paper says that from 2000 - 2014, the 15 - year period that includes the 11 years for which we have ARGO data, the surface warming rate was equivalent to 0.116 degrees per decade — more or less exactly five times the measured ocean warming rate....

Coby, if the earth is warming as a result of increased periodic solar activity (or some other more complex reason) as suggested by the long term cycles mentioned above measured before man was on earth or industrialized, is it posssible that the observed increases in CO2 in the atmosphere are simply coming from warmer oceans, since liquids can not hold as much gas at a higher temperature than they can at lower temperature?

Callendar in the 1930's (AGW a factor in early 20th warming), Plass (radiation balance) and Revelle (oceans won't absorb all anthropogenic CO2) in the 1950's, Keeling measuring CO2 in the 1960's, Manabe and others in the 1970's modelling GHG effects, etc - all contributed to the body of evidence.

Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..

Arguably, the most appropriate single variable in the Earth's system that can be used to measure global warming is ocean heat content - from the surface to the seafloor.

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).

and see if the sun keeps getting cooler... but in the meantime, the measured energy budget keeps getting warmer... the energy continues to go into the ocean.

After that you claimed «HOW you will measure the immeasurable», and I pointed out that the link I already provided was measuring the temperature of the oceans and finding a warming trend.

This time period is too short to signify a change in the warming trend, as climate trends are measured over periods of decades, not years.12, 29,30,31,32 Such decade - long slowdowns or even reversals in trend have occurred before in the global instrumental record (for example, 1900 - 1910 and 1940 - 1950; see Figure 2.2), including three decade - long periods since 1970, each followed by a sharp temperature rise.33 Nonetheless, satellite and ocean observations indicate that the Earth - atmosphere climate system has continued to gain heat energy.34

However, more recent research modelling the impacts of using microbubbles to address global warming found that the technique would not affect ocean primary productivity, a measure of the activity of primary producers.

Answer: if warming releases CO2 from the ocean, whether coming out of an ice age or when initiated by ACO2, it upsets IPCC's model that the bulge in atmospheric CO2 measured at MLO is all due to man.

On the other hand the satellites really do measure the troposphere and they show no significant warming 1978 - 1997 nor 2001 - today, just a small step warming in between these two flat periods and that is coincident with a big ocean event.
