The low
atmospheric temperature also works to slow the reaction, giving additional time for the separation of molecules.
The increased
atmospheric temperatures also allow for more
Not exact matches
Our record is
also of interest to climate policy developments, because it opens the door to detailed comparisons between past
atmospheric CO2 concentrations, global
temperatures, and sea levels, which has enormous value to long - term future climate projections.»
Also associated with this event are high levels of carbon dioxide in the atmosphere, which are linked to elevated ocean and
atmospheric temperatures.
Built out of titanium to withstand the daily Martian
temperature swings from — 22 degrees Fahrenheit -LRB--- 30 degrees Celsius) to — 112 degrees F -LRB--- 80 degrees C), the imager is
also designed to perform in low
atmospheric pressure.
Black carbon aerosols — particles of carbon that rise into the atmosphere when biomass, agricultural waste, and fossil fuels are burned in an incomplete way — are important for understanding climate change, as they absorb sunlight, leading to higher
atmospheric temperatures, and can
also coat Arctic snow with a darker layer, reducing its reflectivity and leading to increased melting.
«It gives further evidence of the close links between
atmospheric CO2 and
temperature, but
also shows how heterogeneous this climate change may be on land,» he adds.
Goddard's computer models, with input from ocean buoys,
atmospheric models, satellite data and other sources, can
also simulate what ocean water
temperatures could do in the coming months.
Bringing together observed and simulated measurements on ocean
temperatures,
atmospheric pressure, water soil and wildfire occurrences, the researchers have a powerful tool in their hands, which they are willing to test in other regions of the world: «Using the same climate model configuration, we will
also study the soil water and fire risk predictability in other parts of our world, such as the Mediterranean, Australia or parts of Asia,» concludes Timmermann.
Differences in moisture content of the beans,
atmospheric pressure, relative humidity,
temperature, density of the coffee, and
also what flavour qualities am I looking to develop and highlight in this coffee — these are now the questions that I consider every day.
But ocean
temperatures alone don't define an El Niño; CPC forecasters
also look for the corresponding shifts in
atmospheric patterns, namely a weakening of the typical east - to - west trade winds over the region.
But this
also means that targets such as stabilizing
atmospheric concentrations of CO2 at 450 parts per million (nearly double preindustrial levels) to avoid more than a 3.6 degree F (2 degree C)
temperature rise are nearly impossible as well.
They have
also developed a technique for using Q - carbon to make diamond - related structures at room
temperature and at ambient
atmospheric pressure in air.
There's
also a tendency for some people just to concentrate on
atmospheric or surface air
temperatures when there are other, more useful, indicators that can give us a better idea how rapidly the world is warming.
While ECS is the equilibrium global mean
temperature change that eventually results from
atmospheric CO2 doubling, the smaller TCR refers to the global mean
temperature change that is realised at the time of CO2 doubling under an idealised scenario in which CO2 concentrations increase by 1 % yr — 1 (Cubasch et al., 2001; see
also Section 8.6.2.1).
For example, in Earth
atmospheric circulation (such as Hadley cells) transport heat between the warmer equatorial regions to the cool polar regions and this circulation pattern not only determines the
temperature distribution, but
also sets which regions on Earth are dry or rainy and how clouds form over the planet.
The transport processes are
also very variable from winter to winter and the amount of ozone pumped into the Arctic is
also correlated with
temperature (this is not a causal relationship — the correlation exists, because variability in
temperatures and in ozone transport are both driven by the same
atmospheric processes).
Increased levels of
atmospheric carbon dioxide could
also significantly alter ocean
temperatures and chemistry over the next century, which could lead to increased and more severe mass bleaching and other stressors on coral reefs.
So the mechanism should cause a decline in skin
temperature gradients with increased cloud cover (more downward heat radiation), and there should
also be a decline in the difference between cool skin layer and ocean bulk
temperatures - as less heat escapes the ocean under increased
atmospheric warming.
We
also know something about the strong relationship between
atmospheric CO2 levels and
temperature.
A natural coupled mode of climate variability associated with both surface
temperature variations tied to El Niño and
atmospheric circulation changes across the equatorial Pacific (see
also «Southern Oscillation Index»).
It
also seems that even though the selective absorption of specific energy bands by different molecules IS the mechanism to add energy to the air, the energy absorbed by CO2 & especially Water Vapor is extremely rapidly dispersed by molecular collisions to ALL the components of the atmosphere, so that the N2 and O2
also heatup, and all the
atmospheric components assume a uniform
temperature (ie global warming).
The transport processes are
also very variable from winter to winter and the amount of ozone pumped into the Arctic is
also correlated with
temperature (this is not a causal relationship — the correlation exists, because variability in
temperatures and in ozone transport are both driven by the same
atmospheric processes).
An parcel means that the medium is small enough to be isothermal and in local thermodynamic equilibrium (which then ensures that the population of thermodynamic molecular energy levels will be set by molecular collisions at the local
atmospheric temperature), but the parcel is
also large enough to contain a large enough sample of molecules to represent a statistically significant mass of air for thermodynamics to apply.
In another post Ferdinand suggested that there
also is the issue of
atmospheric saturation and the
temperature in the air column.
It presents a significant reinterpretation of the region's recent climate change origins, showing that
atmospheric conditions have changed substantially over the last century, that these changes are not likely related to historical anthropogenic and natural radiative forcing, and that dynamical mechanisms of interannual and multidecadal
temperature variability can
also apply to observed century - long trends.
«We
also present a set of global vulnerability drivers that are known with high confidence: (1) droughts eventually occur everywhere; (2) warming produces hotter droughts; (3)
atmospheric moisture demand increases nonlinearly with
temperature during drought; (4) mortality can occur faster in hotter drought, consistent with fundamental physiology; (5) shorter droughts occur more frequently than longer droughts and can become lethal under warming, increasing the frequency of lethal drought nonlinearly; and (6) mortality happens rapidly relative to growth intervals needed for forest recovery.
Moreover, the
atmospheric temperature gradient is mitigated by the absorption of solar radiation within the atmosphere (
also latent heat deposition), thus a more moderate
temperature gradient is established within the ral atmosphere.
And the other sort of latent heat, a decrease in
atmospheric water vapour is
also the stuff of fantasy requiring a change of 50,000 cu km when the atmosphere only contains (and only can contain) ~ 13,000 cu km without crazy
temperature increases.
Although the elevated concentrations of
atmospheric CO2 that raise
temperature can
also raise crop yields, the detrimental effect of higher
temperatures on yields overrides the CO2 fertilization effect for the major crops.
«Instead of the above definition of λ, the global climate sensitivity can
also be expressed as the
temperature change ΔTx2, following a doubling of the
atmospheric CO2 content.
But of course the pace of the
temperature trend
also depends on the global future emissions outlook and on remaining uncertainties surrounding climate sensitivity — or the politically most relevant metric «Equilibrium Climate Sensitivity» (ECS), the amount of warming expected on a decades timescale after doubling of the
atmospheric CO2 concentration.
While the conditions in the geological past are useful indicators in suggesting climate and
atmospheric conditions only vary within a a certain range (for example, that life has existed for over 3 billion years indicates that the oxygen level of the atmosphere has stayed between about 20 and 25 % throughout that time), I
also think some skeptics are too quick to suggest the lack of correlation between
temperature and CO2 during the last 550 million years falsifies the link between CO2 and warming (too many differences in conditions to allow any such a conclusion to be drawn — for example the Ordovician with high CO2 and an ice age didn't have any terrestrial life).
There's
also a tendency for some people just to concentrate on
atmospheric or surface air
temperatures when there are other, more useful, indicators that can give us a better idea how rapidly the world is warming.
The synoptic surface
atmospheric observations assimilated by ERA - Interm are reported as dewpoints and the synoptic message that contains the dew points
also reports
temperature and surface pressure, whose values are needed to compute other humidity variables.
Note,
atmospheric data are not only available on the native 91 model levels, but
also on 37 pressure levels (as in ERA - Interim), 16 potential
temperature levels, and the 2 PVU potential vorticity level.
Indeed, for the impartial spectator, it is hard to figure out, how the Lambda, the Watts, the 3; 3.7 relation to
temperature, the 1.6 Watts / sqm of total global RF (radiative forcing) for the time period (
also labelled as total anthopogenic forcing) 1750 - 2000, the share of Watts / sqm for each
atmospheric constituent, and global
temperature intertwine and produce a senseful scientific meaning.
From the University of California — Riverside, and the department of sulfurous odors, comes this «it must be carbon dioxide» moment: «
Also associated with this event are high levels of carbon dioxide in the atmosphere, which are linked to elevated ocean and
atmospheric temperatures.
It's
also interesting to note that climate scientists have known for at least three decades that short - term fluctuations in
temperature (e.g., those associated with the ENSO cycle) are correlated with short - term fluctuations in the rate of increase of
atmospheric CO2 (Bacastow and Keeling 1981).
The
temperature did not change, so the surface
temperature - dependent responses of
atmospheric radiative cooling
also did not change.
Not only is their conclusion that global warming is primarily due to human activity, but
also that
temperatures will increase significantly because of increases in anthropogenic
atmospheric CO2.
Given the context of this highly anomalous and extremely persistent
atmospheric ridging over the northeastern Pacific Ocean, it's very interesting to note that there has
also been a region of strongly positive sea surface
temperature anomalies in same the general vicinity for the past 10 - 11 months.
How hurricanes develop
also depends on how the local atmosphere responds to changes in local sea surface
temperatures, and this
atmospheric response depends critically on the cause of the change.23, 24 For example, the atmosphere responds differently when local sea surface
temperatures increase due to a local decrease of particulate pollution that allows more sunlight through to warm the ocean, versus when sea surface
temperatures increase more uniformly around the world due to increased amounts of human - caused heat - trapping gases.25, 26,27,28
Pinatubo was particularly good for this, because as Soden et al 2002 showed, the GCMs of the day not only accurately modeled the
atmospheric drying after the eruption, but
also demonstrated that a positive water vapor feedback was required to explain the MSU - measured lower troposphere
temperatures.
Changes in sea - surface
temperatures (SSTs)
also have an effect by bringing about associated changes in
atmospheric circulation and precipitation.
And we
also know that the correlation between global average
temperature and
atmospheric CO2 is statistically not very robust, so that something else must
also «be at work» to cause the gradual warming (or «slow thaw», as you've dubbed it).
< blockquoteOther
atmospheric scientists have
also proposed this (assuming one agrees that a 0.02 °C change in
temperature upon CO2 doubling is the equivalent of a «zero net effect»).
Leaf area index, which is
also enhanced by increasing
atmospheric carbon dioxide, was the second most important factor, contributing an additional 21.8 percent, followed by climate change (precipitation and air
temperature together) and the fraction of photosynthetically active radiation, which accounted for the remaining 18.3 and 14.6 percent increase in NPP, respectively.
Other
atmospheric scientists have
also proposed this (assuming one agrees that a 0.02 °C change in
temperature upon CO2 doubling is the equivalent of a «zero net effect»).
Besides, there is
also a possibility that the Gulf Stream could even increase in
temperature over years to come — adding a cumulative effect to continued
atmospheric warming.
