Sentences with phrase «as changes in the heat content»

Writing in the October 1 issue of Nature, David Victor and Charles Kennel, both of the University of California, San Diego, argue for pegging climate policy to a new «array of planetary vital signs,» such as changes in the heat content of the oceans.

Figure 4 shows the same data as in Figure 3, except expressed as a temperature change rather than as a change in heat content.»

Not exact matches

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

Changes in Hadley circulation affects convection and thus atmospheric moisture content and cloud cover which may in turn affect net solar heating as well as the transfer of heat from Earth to space.

However, lacking global observations of surface mass and ocean heat content capable of resolving year to year variations with sufficient accuracy, comprehensive diagnosis of the events early in the altimetry record (e.g. such as determining the relative roles of thermal expansion versus mass changes) has remained elusive.

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

In 2008, climate change sceptic Roger Pielke Sr said this: «Global warming, as diagnosed by upper ocean heat content has not been occurring since 2004».

Numerous denier arguments involving slight fluctuations in the global distribution of warmer vs cooler sea surface areas as supposed explanations of climate change neglect all the energy that goes into ocean heat content, melting large ice deposits and so forth.

I also usually try to include the change in the Relative Humidity, (if it can be found), in my graphs as humidity plays a part in the atmospheric heat content.

Eg see the map in LWJ06's Fig 2, which shows regional heat content changes, expressed as fluxes, on the order of + / - 50 W / m2.

The only way to make sense of it is to interpret them as saying that sfc t is not conserved, unlike say heat content (which isn't conserved either, but changes in it represent energy flows in and out).

As it happens the total Earth surface change in heat content from 1971 - 2010 was to 274 [196 - 374] zetajoules.

Once again, a group of believers (Leviticus) claims that a strong change is discernable in some aspect of the AGW mythos, yet when the Leviticus paper is actually read, it is clear that as Pielke, Sr. points out, OHC is in reality not doing what is predicted, is significantly lower than the AGW prediction, and that Leviticus offers no mechanism to move this heat fromthe surface to the depths, unless one accepts arm waving as the method of moving heat content.

For as much as atmospheric temperatures are rising, the amount of energy being absorbed by the planet is even more striking when one looks into the deep oceans and the change in the global heat content (Figure 4).

Not all at once of course, but as mentioned above, when the PDO goes positive, we can likely expect a significant change in the atmospheric heat content as heat energy is transferred from the deep oceans back into the atmosphere.

As you know, Isaac Held recently discussed the relative contributions of forced and unforced variations to global surface temperature change in terms of the direction of changes in ocean heat content.

The rate of warming as measured by ocean heat content changes over the last 4 years shows that we have DOUBLED the top - of - atmosphere energy imbalance from 0.6 watts per meter squared to 1.1 watts per meter squared in the last 7 years.

We present an analysis to illustrate why temperature values at specific levels will depend on wind speed, and with the same boundary layer heat content change, trends in temperature should be expected to be different at every height near the surface when the winds are light, as well as different between light wind and stronger wind nights.

They are mainly derived from the Shaviv reference (provided in the link above) that concludes that the solar signal is amplified as indicated by the magnitude of changes in ocean heat content (and other less direct measures) over the course of the 11 year solar cycle.

Because there is no experiment that shows that variations in CO2 concentration over a body of water causes a change in heat content as Kenneth likes to put it?

As for your V&V discussion, I don't see the relevance of it in this talk, but in the context of physical science of climate change we have overwhelming evidence of model usefulness and verification (water vapor feedback, simulating the Pinatubo eruption effects, ocean heat content changes, stratospheric cooling, arctic amplification, etc).

A change in ocean heat content can also alter patterns of ocean circulation, which can have far - reaching effects on global climate conditions, including changes to the outcome and pattern of meteorological events such as tropical storms, and also temperatures in the northern Atlantic region, which are strongly influenced by currents that may be substantially reduced with CO2 increase in the atmosphere.

The natural internal variability of the climate system arises from factors such as El Niño, fluctuations in the thermohaline circulation, and changes in ocean heat content.

Q3 - Does the difference between Tangaroa and Chelle et al imply that a change in DLR does not heat the ocean as much as a similar change in DSR and, therefore, the earth's heat content sensitivity is considerably less for DLR than DSR?

As seen in Figure 4 - 3, the ocean warming occurred in the later years of the record with little change in globally averaged ocean heat content prior to 1997.

The argument that this change it is somehow driven by energy reservoirs in the deep ocean is clearly flawed: the deep ocean would be * cooling * as it lost energy to the upper ocean, but deep ocean heat content is increasing at the same time as OHC in the upper ocean is increasing.

Why are you correlating CFC's against surface temperatures as an indication of what might be occurring rather than against total change in the heat content of the entire system?

Natural variability in air temperature (the lack of significant warming in the last decade) can be regarded as noise in the monotonic increase due to GHGs, but a one year total (ocean) heat content change can't.
