measure of energy content is global average sea level.»
Heating value: Heating value:
A measure of the energy content of the physical unit of any combustible fuel.
First, let me introduce the scientific meaning of temperature: it is
a measure of the energy content of matter.

of breast milk that their children consume, nor will they be able accurately to

Anthropometrics and formula intake were determined monthly; total body bone mineral
content (BMC) and bone mineral density (BMD) were
measured at baseline, 3, and 6 months
of age using dual
energy x-ray absorptiometry.
Dual
energy X-ray absorptiometry (DXA) is a technology that can specifically
measure for fat
content, resulting in a more accurate assessment
of total body fat levels, he explained.
When you eat food, you are consuming
energy stored in a chemical form, the amount
of which can be
measured by the caloric
content (read the Calories Explained article)
of whatever you are eating.
A gallon
of ethanol has a lower
energy content than a gallon
of gasoline (as
measured by BTU
content).
For a long time now climatologists have been tracking the global average air temperature as a
measure of planetary climate variability and trends, even though this metric reflects just a tiny fraction
of Earth's net
energy or heat
content.
The key points
of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the
measured changes
of ocean heat
content over the last decade, iii) the implied planetary imbalance (the amount
of excess
energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.
Higher Heating Value: A
measure of heat
content based on the gross
energy content of a combustible fuel.
One Planet Living principle Masdar Target ZERO CARBON 100 per cent
of energy supplied by renewable
energy — Photovoltaics, concentrated solar power, wind, waste to
energy and other technologies ZERO WASTE 99 per cent diversion
of waste from landfill (includes waste reduction
measures, re-use
of waste wherever possible, recycling, composting, waste to
energy) SUSTAINABLE TRANSPORT Zero carbon emissions from transport within the city; implementation
of measures to reduce the carbon cost
of journeys to the city boundaries (through facilitating and encouraging the use
of public transport, vehicle sharing, supporting low emissions vehicle initiatives) SUSTAINABLE MATERIALS Specifying high recycled materials
content within building products; tracking and encouraging the reduction
of embodied
energy within material sand throughout the construction process; specifying the use
of sustainable materials such as Forest Stewardship Council certified timber, bamboo and other products SUSTAINABLE FOOD Retail outlets to meet targets for supplying organic food and sustainable and or fair trade products SUSTAINABLE WATER Per capita water consumption to be at least 50 per cent less than the national average; all waste water to be re-used HABITATS AND WILDLIFE All valuable species to be conserved or relocated with positive mitigation targets CULTURE AND HERITAGE Architecture to integrate local values.
Global coal consumption, which is
measured in in tonnes
of coal equivalent — the industry standard to reflect
energy content rather than physical weight — will reach 6.2 billion tonnes in 2017, up from 5.3 billion in 2011.
Satellites have the virtue
of measuring total
energy content of the troposphere with a near global coverage.
If you actually had a meter that
measured energy content of storms, that would be the way to go.
(The efficiency
of a power plant is
measured as the percentage
of the total
energy content of that plant's fuel that is converted into electricity.)
Transportation
measures generally contribute a higher percentage to emissions reductions than to
energy use reductions due to the relatively high carbon
content of most transportation fuels.
Regarding the real world earth and the real world atmosphere — granted that the temperature
measures different things for different objects, but in all cases there is a proportionality constant between the (change in) thermal
energy content of an object and its (change in) temperature, and that is the heat capacity.
This is a large part
of the atmospheric
energy content and it is not
measured by thermometers.
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.
At that point you try and
measure changes in heat
content of the upper ocean, more precisely, the flow
of energy into and out
of the upper ocean by
measuring the change in heat
content over time.
The more direct
measure of global warming provided by
measuring the
energy content of the climate system avoids many
of these problems, although the observational record is shorter and less complete (e.g. Church et al 2011).
As you say, the total
energy content of the climate is a more direct
measure of global warming.
Heuristically, the gross moist stability is the difference in
energy content between the air flowing out
of the ITCZ in the upper branch
of the Hadley cell and the air flowing into the ITCZ near the surface; it is also a
measure of the efficiency
of the Hadley cell in moving
energy.
If we could land a man on the moon, why can't we
measure the damn ocean heat
content, before turning over control
of the global
energy economy to R. Gates, fan and Jim D?
All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority
of heat transport to the tropopause), the albedo effects
of clouds, the inability
of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds
of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less
energy to warm than humid air so temperature is not a
measure of atmospheric heat
content.
His proposed broad - based
energy tax would apply to the
energy content of nearly all fuels, as
measured by the British thermal unit, or B.T.U. — the quantity
of heat needed to raise the temperature
of a pound
of water by 1 degree Fahrenheit.
Same goes for temperature, which is a
measure of the thermal
energy content.
