enhance a warming trend.
Claims of
enhanced warming trends and sea level rise are NOT in the raw data.
Not exact matches
According to Dr. Natali, «Our results show that while permafrost degradation increased carbon uptake during the growing season, in line with decadal
trends of «greening» tundra,
warming and permafrost thaw also
enhanced winter respiration, which doubled annual carbon losses.»
That all times of
enhanced coupling would tend to cause a pause in the
warming trend does not seem likely.
Whether the
warming is from greenhouse gases, El Nino's, or solar forcing,
trends aloft are
enhanced.
They concluded that therefore with the tropical troposphere
warming no more quickly than the surface, the
warming trend had to be due to something other than the accumulation of greenhouse gases and
enhanced greenhouse effect.
Re 9 wili — I know of a paper suggesting, as I recall, that
enhanced «backradiation» (downward radiation reaching the surface emitted by the air / clouds) contributed more to Arctic amplification specifically in the cold part of the year (just to be clear, backradiation should generally increase with any
warming (aside from greenhouse feedbacks) and more so with a
warming due to an increase in the greenhouse effect (including feedbacks like water vapor and, if positive, clouds, though regional changes in water vapor and clouds can go against the global
trend); otherwise it was always my understanding that the albedo feedback was key (while sea ice decreases so far have been more a summer phenomenon (when it would be
warmer to begin with), the heat capacity of the sea prevents much temperature response, but there is a greater build up of heat from the albedo feedback, and this is released in the cold part of the year when ice forms later or would have formed or would have been thicker; the seasonal effect of reduced winter snow cover decreasing at those latitudes which still recieve sunlight in the winter would not be so delayed).
[Response: There is evidence that the
enhanced continental winter
warming in the Northern Hemisphere, which has resulted at least in part from a recent
trend towards the positive phase of the Arctic Oscillation (AO), may in fact also represent a response to anthropogenic impacts on climate.
Anthropogenic global
warming (AGW), a recent
warming of the Earth's lower atmosphere as evidenced by the global mean temperature anomaly
trend [11], is BELIEVED to be the result of an «
enhanced greenhouse effect» mainly due to human - produced increased concentrations of greenhouse gases in the atmosphere [12] and changes in the use of land [13].
However, Helbig et al. [2017], using a set of nested paired eddy covariance flux towers in a boreal forest - wetland landscape, point to the increasing importance of
warming temperatures on ecosystem respiration potentially overwhelming
enhanced productivity occurring from land cover change under projected anthropogenic
trends.
The NASA / GISS laboratory located at Columbia has long been «
enhancing» global
warming trends from the raw empirical evidence - truly an art form in its own right, sans the mattress of course.
Again, no significant
trend of the global averaged Gaa [atmospheric greenhouse effect] is found from 2003 to 2014 (Fig. 2) because the
enhanced warming effect over the western tropical Pacific is largely counteracted by the weakened
warming influence on the central tropical Pacific.
So I asked Mr. Knappenberger to test the models» agreement with long - term observations using a new «third» scenario in which internal variability once again «
enhances» the «externally forced
trend» and global
warming resumes at the 1984 - 1998 rate of 0.265 ºC / decade.
During this cooling
trend, there were several
warm spikes, usually associated with life -
enhancing inflows of both
warm Pacific and Atlantic water.
One, the overall
warming trend is
enhanced, which is then attributed to increased CO2 by the government agency scientists, versus stating that their underlying temp adjustments were the real «enhancement» cause.
As the adjacent chart from the NTZ article documents, NOAA's definitive manipulations of a U.S. states climate records to
enhance the modern global
warming trend is indisputable.
As a result, the NASA / GISS climate agency has shown their amazing «scientific» capabilities by producing an
enhanced global
warming trend... by simply, and literally, lowering (ie, cooling) past recorded temperatures prior to 1960.
Anthropogenic global
warming (AGW), a recent
warming of the Earth's lower atmosphere as evidenced by the global mean temperature anomaly
trend [9], is believed to be the result of an «
enhanced greenhouse effect» mainly due to human - produced increased concentrations of greenhouse gases in the atmosphere [10] and changes in the use of land [11]..
Responding to and in the manner of KK Tung's UPDATE (and, you can quote me): globally speaking the slowing of the rapidity of the
warming, were it absent an
enhanced hiatus compared to prior hiatuses, must at the least be interpreted as nothing more than a slowdown of the positive
trend of uninterrupted global
warming coming out of the Little Ice Age that has been «juiced» by AGW as evidenced by rapid
warming during the last three decades of the 20th Century, irrespective of the fact that, «the modern Grand maximum (which occurred during solar cycles 19 — 23, i.e., 1950 - 2009),» according to Ilya Usoskin, «was a rare or even unique event, in both magnitude and duration, in the past three millennia [that's, 3,000 years].»
This mirrors the significant rise in global temperatures detected over the past 30 years, supporting the conclusion that there is a global
trend toward
enhanced glacier frontal recession in recent decades and providing support for the assertion that glacier recession can be attributed to recent
warming.»
Simulations of the
enhanced greenhouse effect forecast a
warming trend of approximately 0.25 to 0.35 º C per decade, or accelerated
warming compared to the surface.
We found that relative to the global - mean
trends of the respective layers, both hemispheres have experienced
enhanced tropospheric
warming and stratospheric cooling in the 15 to 45 ° latitude belt, which is a pattern indicative of a widening of the tropical circulation and a poleward shift of the tropospheric jet streams and their associated subtropical dry zones.
In a worldwide set of about 270 stations, Parker (2004, 2006) noted that
warming trends in night minimum temperatures over the period 1950 to 2000 were not
enhanced on calm nights, which would be the time most likely to be affected by urban
warming.
