Wu, Lee, and Liu (2005) said: «The 1970s North Pacific climate regime shift is marked by a notable transition
from the persistent warming (cooling) condition over the central (eastern) North Pacific since the late 1960s toward the opposite condition around the mid 1970s... This large - scale decadal climatic regime shift has produced far - reaching impacts on both the physical and biological environment over the North Pacific and downstream over North America.»
By this, I imply that some sort of negative feedback may prevent the planet
from persistent warming, thus making «global warming» innacurate.
Not exact matches

warm winds were so
persistent, lasting 350 years, the team combined their data with information
from other regions of the world.
It is possible, he adds, that these
persistent high - pressure zones may be produced by two well - known oceanographic patterns: La Nina and El Nino in the Pacific Ocean (which mark alterations in
warmer and cooler conditions between that ocean's eastern and western equatorial waters) and the North Atlantic Oscillation (which results
from weather patterns between Iceland and the Azores).
Updated, 7:48 p.m. On time scales
from decades to months, fluctuations in ocean conditions present
persistent challenges to climate scientists (see the «pause» in
warming) and weather forecasters.
Pieter Tans of the National Oceanic and Atmospheric Administration stressed the
persistent uncertainty in the range of
warming expected
from a buildup of greenhouse gases as cutting against the idea of specific thresholds: «Our biggest science problem is that we do not know how strong the climate feedbacks are, or even whether we know all of the ones that are important on decadal and longer time scales,» he said in an e-mail.
As I've explained before, there is enormous potential for progress on climate - smart energy steps even in the face of
persistent division over the extent of the threat
from global
warming.
In a phone chat, Cicerone at the academy described Schneider's core traits, particularly his approach to forging policies that made sense even in the face of the
persistent uncertainty about the worst - case impacts
from warming:
But, given the
persistent lack of clarity on how much the world will
warm from a certain buildup of greenhouse gases and the divergent views around the world on what an ideal climate is in any case, is this threshold meaningful or useful?
While
persistent and deep uncertainty surrounds the most important potential impacts
from and responses to greenhouse - driven global
warming (see David Roberts, Michael Levi and this list of reviewed research for more), the long - term picture of a profoundly changed Earth is clear.
Setting aside the word propaganda, I will readily assert that there has been a longstanding and well - financed effort to raise public concern by downplaying substantial,
persistent and legitimate uncertainty about the worst - case outcomes
from greenhouse - driven
warming and over-attributing the link between such
warming and climate - related disasters and other events.
Overall, the panel's reports have never focused much on research examining how humans respond (or fail to respond) to certain kinds of risk, particularly «super wicked» problems such global
warming, which is imbued with
persistent uncertainty on key points (the pace of sea - level rise, the extent of
warming from a certain buildup of greenhouse gases), dispersed and delayed risks, and a variegated menu of possible responses.
That approach,
from Katrina forward, was bound to fail, given the variability of conditions year to year and
persistent (and non-manufactured) uncertainty surrounding some of the most consequential impacts (for instance, the pace and extent of
warming and sea - level rise in this century).
If these
warm ocean temperatures occur in combination with abnormally
warm conditions near Alaska, the extra heat
from the Arctic can intensify the ridge, causing it to reach farther northward, become more
persistent, and pump even more heat into the region near Alaska.
In this new paper they write: «The most striking features in the reconstruction are the
warm temperatures
from ∼ 1050 to ∼ 1300 AD compared to the preceding and following centuries, the
persistent cooler temperatures
from ∼ 1400 to ∼ 1800 AD, and the subsequent rise to
warmer temperatures which eventually seem to exceed in the last decades of the 20th century the range of past variation.
But observations
from recent years support the idea that the melting ice is a key factor in shaping the
persistent pattern of
warm temperatures over the Arctic that displaces bitter cold air toward North America and especially Eurasia, says conference co-chair Judah Cohen, a climate scientist at the Massachusetts Institute of Technology.
While
persistent and deep uncertainty surrounds the most important potential impacts
from and responses to greenhouse - driven global
warming, the long - term picture of a profoundly changed Earth is clear.
The first clause is «While
persistent and deep uncertainty surrounds the most important potential impacts
from and responses to greenhouse - driven global
warming....»
The original question: While
persistent and deep uncertainty surrounds the most important potential impacts
from and responses to greenhouse - driven global
warming, the long - term picture of a profoundly changed Earth is clear.
As someone who won't accept the global
warming mantra I can often be discouraged by the
persistent abuse, be it in the small form «science - denier» or the worse «Big oil shill» and up to «you are killing our grandchildren» but I keep heart that the observation will continue to diverge
from the prediction and someone will eventually shout loud enough... «but he's not wearing any clothes».
If my view is correct, then
warming is equal to the more
persistent change when the two years being compared have a similar deviation
from the expectation.
It's plausible that 1951 and 2010 are such a pair, and therefore the total
warming from 1951 to 2010 might well equal the human influence which is of more
persistent nature.
«California's driest and
warmest years are almost always associated with some sort of
persistent high pressure region, which can deflect the Pacific storm track away
from California,» Swain says.
An average of the ice core water stable isotope timeseries
from West Antarctica suggests
persistent warming through the second half of the twentieth century (Schneider and Steig 2008), as do ice cores
from the western side of the Antarctic Peninsula (e.g. Thomas et al. 2009).
Hicks Pries CE, van Logtestijn RSP, Schuur EAG, Natali SM, Cornelissen JHC, Aerts R, Dorrepaal E (2015b) Decadal
warming causes a consistent and
persistent shift
from heterotrophic to autotrophic respiration in contrasting permafrost ecosystems.
The more people understand
from an early age that science advances in stutter steps through testing, failure, and argument, the less likely they'll be to interpret some of the
persistent disputes over important facets of global
warming to mean society can simply sit back and wait for a magical solution...
Last winter also showed a change
from the previous two winters when cold plunges over the USA distorted the jets and gave us
persistent warm wet south westerlies so we did not then share in the general slow cooling trend.
The number of ensemble members generated was 40, but some ensemble members that exhibit a
persistent warming drift and do not reach steady states during their doubled CO2 experiment are excluded
from the analysis in the same way as Y10.
Sea ice in the Bering Sea this winter was said to be the lowest since the 1850s, largely driven by
persistent winds
from the south rather than the usual north winds although
warm Pacific water was a factor early in the season (AIRC 2018).
From the quotes available it appears she said an increase in heavy precipitation events and
persistent storm tracks further south is consistent with global
warming projections — not that global
warming would cause the jet stream to «get stuck.»
