The broad - brush elements are familiar: they set an initial ceiling on the amount of climate -
warming emissions allowed in the industrial, electricity, transportation and other sectors, then gradually lower this ceiling over the years, while creating emission allowances that can be traded among polluting industries.
Not exact matches

emissions — which are, through global
warming, melting the artic sea ice used by the polar bears for hunting — from regulation under the Endangered Species Act.)
Moreover, to level the playing field and
allow all new innovations to compete, you should support a cap on CO2
emissions to limit global
warming or accomplish the same by placing a tax on carbon
emissions.
Although climate patterns in the future may not exactly mimic those conditions, the period of
warming allowed Petrenko to reveal an important piece of the climate puzzle: natural methane
emissions from ancient carbon reservoirs are smaller than researchers previously thought.
In accordance with California's Global
Warming Solutions Act's (AB32) guidance, the ROW recommends that California
allow states or countries that reduce their total
emissions from deforestation below an historical average to generate compliance credit in California.
This large uncertainty makes it difficult for a cautious policy maker to avoid either: (1)
allowing warming to exceed the agreed target; or (2) cutting global
emissions more than is required to satisfy the agreed target, and their associated societal costs.
The longevity of global
warming (Fig. 9) and the implausibility of removing the
warming if it is once
allowed to penetrate the deep ocean emphasize the urgency of slowing
emissions so as to stay close to the 500 GtC target.
This approach is complementary to the approach of estimating cumulative
emissions allowed to achieve a given limit on global
warming [12].
It also provides cleaner
emissions by
allowing for quicker
warm - up of the catalyst and by stabilizing combustion when the engine is cool.
And if you buy the IPCC's reports (figuratively speaking) the world is only about eight years away from the «deadline» the IPCC has identified for
allowing emissions to peak and begin their descent if the world is to stand a 50 - 50 chance of holding global
warming to about 3.6 degrees Fahrenheit by century's end.
The fact that Christy and Pielke Sr. are scientists
allows their skeptical positions on rapid GHG driven global
warming to be even harder to deal with when I attempt to inform people that rapid GHG driven global
warming is happening and that humans need to act quickly to reduce GHG
emissions in order to delay and to reduce the catastrophe that lies ahead due to global
warming.
Until now, power plants have been
allowed to dump unlimited amounts of carbon pollution into the atmosphere — no rules were in effect that limited their
emissions of carbon dioxide, the primary driver of global
warming.
We conclude that this scenario offers three attractive characteristics: environmental security, because the global carbon budget is set at a level which keeps global
warming below 2 degrees; economic efficiency, because carbon trading
allows the reductions to be made for least overall cost; and global social justice, because
emission rights are allocated equally to all people.
Detailed studies at the State Hydrology Institute in St. Petersburg
allow one to assume that biogenic methane
emission in the Russian permafrost zone can not increase by more than 20 %, or at the most 30 %, compared to the current level, which would cause global
warming by 0.01 degrees Celsius by 2050.
And according to
emissions specialists like the Tyndall Centre's Kevin Anderson (as well as others), so much carbon has been
allowed to accumulate in the atmosphere over the past two decades that now our only hope of keeping
warming below the internationally agreed - upon target of 2 degrees Celsius is for wealthy countries to cut their
emissions by somewhere in the neighborhood of 8 — 10 percent a year.27 The «free» market simply can not accomplish this task.
Maybe you don't know much about the sum of radiative forcings, or findings from paleoclimate, that
allow climatologists to calculate that human
emissions of greenhouse gases are responsible for 100 + % of recent
warming, but that doesn't mean nobody does.
Just the opposite, evidence shows that CO2 provides the building block for the terrestrial greenhouse effect, both because it absorbs strongly near the peak
emission for Earth, and because it
allows Earth to be
warm enough to sustain a powerful water vapor greenhouse effect.
In
warmer years such as 1998, this outgassing also increases, and that correlation is seen in the data, so you have to
allow for that when comparing the increase to
emissions.
It adopted a moderate anthro -
emissions scenario from AR4 as the AGW input, but set arbitrary constraints on its findings by excluding the greenhouse gas outputs»
warming from the assessment of the permafrost's rate of melting, and by assuming that only CO2 was emitted - which
allowed the projected future output to be stated in simple carbon tonnage.
Risk of Sudden Catastrophic
Warming This concern stems directly from the possibility that the prospect of successful geoengineering would make
emissions reductions seem less urgent,
allowing more and more carbon dioxide to build up in the atmosphere over the century ahead.
The relationship between cumulative
emissions and peak
warming allows us to show how delaying mitigation in the short term creates the need for more rapid
emission reductions later, in order to stay below a given cumulative
emissions limit.
Oh, evil global
warming and carbon
emissions that
allow more vegetation to flourish.
Emissions before 2010 are not
allowed to vary across
emission pathways, so there can be no contribution to the spread in peak
warming from this historical time period.
According to these models our past
emissions are already enough to cause global
warming to exceed the 0.5 degrees of future
warming allowed under the 1.5 degree Paris target.
When you
allow for
emissions of methane, CFCs, ozone, nitrous oxide and soot — which also
warm the atmosphere — the carbon dioxide budget is an even tighter 3,200 billion tonnes, note Pierre Friedlingstein and colleagues in the paper.
Increasing the supply of renewable energy would
allow us to replace carbon - intensive energy sources and significantly reduce US global
warming emissions.
It has been difficult to explain why the Earth started
warming in the 1970's and that lack of explanation has
allowed the warmist crowd to convince many people that the CO2
emissions of mankind are the cause.
Previously, power plants were
allowed to dump unlimited amounts of carbon pollution into the atmosphere — no rules were in effect that limited their
emissions of carbon dioxide, the primary driver of global
warming.
Our analysis shows that China's
emissions might not peak until 2030, but by then its annual
emissions could amount to half of the carbon budget — what is
allowed in order to stay within the 2 °C
warming target.
This approach
allows us to examine what the models say about future
warming relative to future
emissions, without bringing in any potential model bias simulated over the historical period.
This linear relationship is a useful insight, because it means that for any target ceiling for temperature rise (e.g. the UN's commitment to not
allow warming to rise more than 2 °C above pre-industrial levels), we can easily determine a cumulative
emissions budget that corresponds to that temperature.
Ironically, these aerosols are also the product of fossil fuel burning and strict regulations were imposed in the developed world on their
emissions in the 1960s and 1970s which
allowed the
warming from carbon dioxide to emerge again.
The commitments to
emissions reductions, which will be included in the Accord by the end of January (but can already be surprised from national pledges), would
allow warming to reach at least 3 °C above pre-industrial levels, according to the best available science (and according to a leaked UN document).
Peters is a researcher who is on the record stating that he thinks there's little chance of holding
warming to 2 degrees Celsius unless we come up with so - called «negative
emissions» technologies that
allow us to actively withdraw carbon dioxide from the atmosphere later in the century.
