Curry's evidence to support that assertion boiled down to arguing of a supposed «
lack of warming since 1998», discrepancies between models and observations during that time, a lower climate sensitivity range in the 2014 than the 2007 IPCC report, and the fact that Antarctic sea ice extent has increased.
And, if you've been following the discussion, and particularly the climategate emails, you'll know that alarmist climate science has been in a flap over
the lack of warming since at least 2005 and is making desperate attempts to explain it (away).
Interestingly, none of those who opposed the anthropogenic argument were willing to confront an ally on purported facts, such as
the lack of warming since 1940.
for
lack of warming since 1998» refers to a model that does address serial correlation (being based on Kaufman, A., H. Kauppi, and J. H. Stock, 2006: «Emissions, concentrations and temperature: a time series analysis.»
If you are referring to the «globally and annually averaged land and sea surface temperature anomaly», then this indicator has shown «cooling» since the end of 2000 (12 years) and
lack of warming since the end of 1997 (15 years).
Because rest assured that
the lack of any warming since 1997 will be haunting you from now until (if ever) you do have an explanation.
Note that I am not the one claiming
a lack of warming since 1997.
I agree that
the lack of warming since 1998 is often over-emphasised.
Not exact matches
In earlier findings, Ruben argued that CAT scans
of dinosaur nasal structure clearly suggested that dinosaurs were not
warm - blooded,
since they
lacked the nasal «turbinates» that
warm - blooded animals use to prevent excess heat and water loss while breathing.
Since ski season is upon us (even though there is a
lack of snow on the mountains), I thought it would be helpful to share some packing essentials to stay
warm & still look chic!
Curry uses the
lack of data to attribute all the early 20th century
warming to internal variability which she then projects willy - nilly onto the late 20th century to provide 50 %
of the
warming since 1950 and perhaps even amplifies it to allow for the continuing
warming and / or attribution
of more - than - 50 %
of post-1950
warming to internal variability.
The author shows this
lack with his statement «For which, by the way, there is no natural explanation, and the best estimate for the anthropogenic share
of global
warming since 1950 is 110 percent — more on this in my previous post.»
Since most
of our knowledge
of global
warming is obtained in the form
of abstract scientific knowledge, most individuals in the U.S.
lack direct unambiguous personal experience with this problem.
Interestingly, the paper «Climate Trends and Global food production
since 1980» (Lobell, Schlenker, Costa - Roberts, in Sciencexpress, 5 May, Science 1204531) confirms my finding
of the absence
of climate change in the USA: «A notable exception to the [global]
warming pattern is the United States, which produces c. 40 %
of global maize and soybean and experienced a slight cooling over the period... the country with largest overall share
of crop production (United States) showed no [adverse] effect due to the
lack of significant climate trends».
I will try to get some more specific answers for you and either correct or fill out this article, but I think the main gist
of the argument is that there are other factors at play and the simple
lack of a perfect correlation does not mean that CO2 is not the primary driver
of the general
warming seen
since 1900.
«
Since 1997, when Pinatubo's aerosol settled out, the stratosphere has been exceptionally clear... Half or more of the warming since 1995 may due to the lack of large volcanic eruptions... That's about 0.13 °C... The remaining climate change is presumably caused by other forces, such as solar variability, El Nino, Atlantic AMO warming in 1995, lower Albedo and maybe even a little greenhouse gas.&r

At least the usual suspects think so
since they're blaming the
lack of warming for the past 15 years on it as well as the
lack of warming from 1940 to 1980.
For example, Jones agreed with the BBC interviewer that there had been «no statistically significant
warming»
since 1995 (although he asserted that the
warming was close to significant), whereas in his 2005 email he was at pains to hide the
lack of warming from the public and even fellow researchers.
Nov 9, 2015 Stefan Rahmstorf bemoans the
lack of action on global
warming since 1965, when scientists issued the first warning.
In summary, the table depicts (for those listed climate records) the
lack of statistically - significant
warming since mid-1997.
The adjacent chart clearly depicts the
lack of the predicted global
warming since the decade
of the 1990s.
These omissions included: (a) the
lack of recognition that dependence on natural gas as a bridge fuel for reducing the US carbon footprint raises several ethical questions, a matter reviewed here in detail, (b) acknowledgment
of the US special responsibility for climate change for its unwillingness to take action on climate change for over 20 years
since it ratified the United Nations Framework Convention on Climate Change in 1992, see, The World Waits In Vain For US Ethical Climate Change Leadership As the World
Warms, and, (c) failing to communicate the extreme urgency
of quickly and significantly reducing ghg emissions in the next few years to give the world any hope
of avoiding dangerous climate change, see, On the Extraordinary Urgency
of Nations Responding To Climate Change on the Basis
of Equity.
And do let us know why, if satellite measurements can be trusted to show the earth's temperature rise, the
lack of a
warming trend in the sun
since 1970 is somehow suspect.
There has been no «global
warming»
since 1998 (HadCRUT4), so it is absurd to ask whether this
lack of global
warming was caused by humans or is natural.
Through a quirk
of statistics, the
lack of warming observed
since the IPCC's Fourth Assessment Report has added about one - tenth
of a degree to the overall global
warming since 1900.
And
since the Arctic (more so than the Antarctic) is
warming faster than the global average, the
lack of data there may mean that the global average temperature trend may be underestimated.
HadCRUT attributed the «
lack of warming» over the past decade (despite CO2 concentrations reaching record levels) to «natural variability» (a.k.a.natural forcing), while IPCC told us in AR4 that the total effect
of «natural forcing components»
since 1750 was essentially negligible compared to the impact
of CO2.
It will also include scientifically refuting the apparent falsification
of the above «dangerous AGW» hypothesis, which has resulted from the observed «
lack of warming»
of our planet over the past decade (atmosphere, at both the surface and troposphere
since 2001, sea surface temperature
since ARGO measurements were installed in 2003), despite record increase in atmospheric CO2, as measured at Mauna Loa, by demonstrating with empirical data where the «missing energy» is hiding.
You aren't thinking about the
warming period early last century, because we know it was a relatively brief period, and so
lacked huge significance, and was caused by a combination
of CO2 emissions, high solar activity and low volcanic activity and the later two factors haven't been apparent
since the 1970's modern
warming period.
The
lack of warming for more than a decade — indeed, the smaller - than - predicted
warming over the 22 years
since the UN's Intergovernmental Panel on Climate Change (IPCC) began issuing projections — suggests that computer models have greatly exaggerated how much
warming additional CO2 can cause.
The
lack of statistical significance in temperate trends
since 1998 is at least partly a statistical power issue - there is not enough data (
since 98) to achieve a statistically significant result, even if there has been
warming.
Bearing in mind the
lack of stratospheric cooling (apparently the one true signature
of AGW according to realclimate.org and the IPCC)
since 1995 and the pause in tropospheric and surface
warming since that «unnatural» 1985 - 1998 rise, some now like to claim the «plateau» is due to a waning sun.
Further, with mean temperatures across Australia generally well above average
since September 2012, long periods
of warmer - than - average days have been common, with a distinct
lack of cold weather, the statement says.
