Around the accretion disk are relatively dense clouds of hot gas that could be responsible for the broad
emission lines seen in Type 1 Seyferts.

It's great to

emission vehicle strategy, and plans to make Canada's clean power go further with new transmission
lines.
Another aspect of the plan that is likely to
see significant airing in future hearings is the rule's «outside the fence
line» approach, which allows states to look beyond power plant modifications to demand - side efficiency and the adoption of renewable energy when controlling greenhouse gas
emissions.
With the correlated signals measured on each baseline (the imaginary
line connecting the two telescopes as
seen from the observed source), an image of the
emission surrounding the black hole can eventually be reconstructed.
According to the recent Snow, Water, Ice and Permafrost in the Arctic report, if we reduce
emissions roughly in
line with the Paris Agreement, we would
see an additional 54 centimeters of global sea level rise by 2100.
It was something the team had hoped to
see for years, and when the telltale, broad -
emission lines showed up on the Keck Observatory monitors, the mood in the room lit up.
An interesting result from this data was that no
emission was detected in the Stokes I spectral
line profiles during the flare, which is traditionally
seen in such magnetic transient regions.
We characterize the main
emission lines found in the spectrum, which primarily arise from a range of components associated with Orion KL including the hot core, but also
see widespread
emission from components associated with molecular outflows traced by H2O, SO2, and OH.
«We frequently
see the Lyman - alpha
emission line of hydrogen in nearby stars,» says Adi Zitrin, the discovery paper's lead author.
The summer of 2017
saw the 300,000 th G - Class roll off the assembly
line in Graz — a Mercedes - Benz G 500 in designo Mauritius blue metallic with black leather seats and contrasting white topstitching (combined fuel consumption: 12.3 l / 100 km; combined CO2
emissions: 289 g / km).
the new Mazda family face, and new lamp designs front and back, for sportiness and a more premium identity that can be
seen at first glance, a powertrain
line - up with six engines — including three derivatives of the 2.2 - litre turbo diesel and a new 2.0 - litre DISI petrol engine — all of them even more frugal and with lower
emissions, a new five - speed automatic transmission developed especially for the new DISI petrol to ensure optimal acceleration behaviour and fuel economy.
And we do so (
see the Appendix) for a global emergency
emissions reduction pathway that is stringent enough to provide a high probability of holding the 2ºC
line.
The only thing I
see is that the ocean temperature has had its oscillations but has generally increased at a constant rate since 1900 but other literature show anthropogenic
emissions have increased exponentially from 1900 to 2006 I
see no correlation between a straight
line and an exponential curve.
State and total populations on land and major cities in which the majority of the population occupies land committed to fall below future high tide
lines given
emissions through 2100 under RCP 2.6 (blue city markers on both maps) or 8.5 (red city markers) and assuming the baseline Antarctic case (
see text).
«Smart investors can already
see that most fossil fuel reserves are essentially unburnable because of the need to reduce
emissions in
line with the global agreement by governments to avoid global warming of more than 2 °C.
So as Nick Stokes points out (in a comment below), we can draw a
line around the whole climate system, including the
emission of radiation by the sun (
see example 4 just below).
At CDP, we are
seeing many companies already playing their part through setting
emissions reduction targets in
line with climate science, committing to using 100 % renewable electricity or working to remove commodity - driven deforestation from supply chains.
So, it's hard to
see how the yellow
line (carbon dioxide
emissions) could be the main reason for changes in the red
line.
To the extent possible, the scenarios were mutually consistent, such that scenarios of population (United Nations medium range estimate) and Gross Domestic Product (GDP)(moderate growth) were broadly in
line with the transient scenario of greenhouse gas
emissions (based on the Goddard Institute for Space Studies (GISS) scenario A,
see Hansen et al., 1988), and hence CO2 concentrations.
Were
emissions trading to occur across state
lines, of course, low - cost states would
see credit prices go up, and high - cost states would
see credit prices go down.
The bottom
line: don't get excited about headlines about falling
emissions unless they fall so much that we start
seeing significant changes in atmospheric accumulation.
Note that the results are quite in
line with what the UK's Hadley Center recently reported (
see Hadley Center: «Catastrophic» 5 — 7 °C warming by 2100 on current
emissions path, but this is a better figure than Hadley's, I think).
I had
seen a written interview with Steinacher shortly after the study was published, and his bottom
line was that
emissions reductions would have to be roughly doubled over those from the temperature - only case.
It's worth noting that in another
emissions area, methane, we
see a similar trend
line associated with
emissions from natural gas development — falling — and for similar, market - based reasons.
If a certain type of gas produces absorption
lines at certain wavelengths when it is in front of a hot background, then when that same type of gas is
seen in front of a cooler background, it produces
emission lines at the exact same wavelengths.
Those nice Balmer spectra and the like from Mercury vapor lamps or Sodium lamps and the like are observed in VERY LOW DENSITY gases, where the mean time between molecular or atomic collisions is much longer than the lifetimes of the excited states, so that spontaneous
emission can occur; only then do you get the bright
line spectra as
seen in those HOT gases.
Among the
line's zigs and zags you can
see the angle of the
emissions line is down, starting around 2008 — which coincides with the onset of America's shale energy revolution.
These discrete, isolated wavelengths are called the «
emission lines» of the spectrum, because if you were to pass the radiation through a prism, you would
see isolated
lines of different colors.
