Climate engineering is making an already horrific
anthropogenic warming scenario far worse overall.
Not exact matches
Although the scientific credibility of the film drew criticism from climate scientists, the
scenario of an abrupt collapse of the AMOC, as a consequence of
anthropogenic greenhouse
warming, was never assessed with a state - of - the - art climate model.
To be consistent with recent observations,
anthropogenic warming is likely to lie in the range 0.1 to 0.2 °C / decade over the next few decades under the IS92a
scenario.
1,3 °C Spencer 2018
Scenario: only 70 % of the
warming of the past 150 years is
anthropogenic.
Both
scenarios are far less plausible than the simple attribution of most (90 %) industrial global
warming to
anthropogenic effects, rather than to the Sun.
Third, with our ∼ 1 °C
scenario it is more likely that the biosphere and soil will be able to sequester a substantial portion of the
anthropogenic fossil fuel CO2 carbon than in the case of 2 °C or more global
warming.
In Figure 4, Huber and Knutti break down the
anthropogenic and natural forcings into their individual components to quantify the amount of
warming caused by each since the 1850s (Figure 4b), 1950s (4c), and projected from 2000 to 2050 using the IPCC SRES A2 emissions
scenario as business - as - usual (4d).
«To be consistent with recent observations,
anthropogenic warming is likely to lie in the range 0.1 to 0.2 Â °C / decade over the next few decades under the IS92a
scenario.»
To be consistent with recent observations,
anthropogenic warming is likely to lie in the range 0.1 to 0.2 °C / decade over the next few decades under the IS92a
scenario.
This is a much more serious
scenario than «regular»
anthropogenic GW, because the
warming could be amplified, eventually thawing methane clathrates, and the
warming could then really spiral to an massive extinction event level (as happened 251 million years ago when up to 95 % of life on earth died).
BACK TO TOPIC: If CO2 & CH4 are important forcings in a linear GW
scenario, then in a «runaway» GW
scenario of the
warming triggering further mechanisms of
warming, triggering further mechanisms, our
anthropogenic GHG emissions have even more ultimate impact.
Those who support the theory of
anthropogenic global
warming (AGW), now known as
anthropogenic climate change so that recent cooling can be included in their
scenario, always deny that the sun has anything to do with recent global temperature movements.
We have massive evidence coming out on an almost daily basis that there is no
anthropogenic global
warming, that CO2 doesn't cause jack and that there have been plenty of people lying like rugs about it, altering data to fit their global
warming scenario, using tainted data, etc..
Well, in a nutshell, the
anthropogenic global
warming hypothesis, which is at the center of modern climate - doomsday
scenarios, can not explain the powerful
warming of the past.
For existing assets, our research can highlight which ones are more at risk of becoming stranded under a lower demand
scenario — for example one that restricts
anthropogenic warming to 2 °C.
In fact, it is extremely difficult to construct a physically plausible
scenario in which less than 50 % of the
warming since 1950 was
anthropogenic; that's why this hypothesis was rejected at the 95 % level.
In Figure 4, Huber and Knutti break down the
anthropogenic and natural forcings into their individual components to quantify the amount of
warming caused by each since the 1850s (Figure 4b), 1950s (4c), and projected from 2000 to 2050 using the IPCC SRES A2 emissions
scenario as business - as - usual (4d).
In the worst - case
scenario, this is cemented in the public mind as a refutation of the connection between
anthropogenic carbon emissions and global
warming, and ongoing projects to eliminate carbon will be reversed.
We estimate that
anthropogenic influence has caused a more than 60-fold increase in the likelihood of the extreme
warm 2013 summer since the early 1950s, and project that similarly hot summers will become even more frequent in the future, with fully 50 % of summers being hotter than the 2013 summer in two decades even under the moderate RCP4.5 emissions
scenario.
Over that time, the globally averaged temperature difference between the depth of an ice age and a
warm interglacial period was 4 to 6 °C — comparable to that predicted for the coming century due to
anthropogenic global
warming under the fossil - fuel - intensive, business - as - usual
scenario.
«Scientists were quick to declare the results of the Turner et al paper, which covered 1 per cent of the Antarctic continent, did not negate a long - term
warming because of man - made climate change... «Climate model projections forced with medium emission
scenarios indicate the emergence of a large
anthropogenic regional
warming signal, comparable in magnitude to the late - 20th - century peninsula
warming, during the latter part of the current century,» the Turner research concluded.»
It seems to me that
anthropogenic global
warming fits that
scenario to a «T.»
Anthropogenic warming by the end of the 21st century will likely cause tropical cyclones globally to be more intense on average (by 2 to 11 % according to model projections for an IPCC mid-range
scenario).
Even in that
scenario, it seems to me that the question is whether or not the measured temperature is or is not
warmer than it would be without the measured dramatic increase in
anthropogenic atmospheric CO2.
They found that
warming in the extra-tropical Northern Hemisphere was highly related to the two teleconnections, and it led them to conclude (hold your breath) that their results «do not support the
scenario that the emerging influence of the AO - like pattern in the late 1980s can be attributed to the
anthropogenic greenhouse effect.»
Anthropogenic global
warming under a standard emissions
scenario is predicted to continue at a rate similar to that observed in recent decades.
