The climate in most places has undergone minor changes over the past 200 years, and the land - based surface temperature record of the past 100 years
exhibits warming trends in many places.
The climate in most places has undergone minor changes over the past 200 years, and the land - based surface temperature record of the past 100 years
exhibits warming trends in many places.
Your map in Figure 3a (and the cover of Nature) gives the casual reader the perception that all of Antarctica has
exhibited a warming trend from 1957 - 2006, when in fact, it seems that at least one location, direct, local observations indicate otherwise.
If both areas
exhibit the warming trend, that would seem to argue persuasively against human causation, wouldn't you agree?
3) In order to assert human causation, I would think the data would have to show that, for example, Rocky Mountain National Park had continued unabated to the present day the cooling trend established from approximately 1750 through 1850, while the Houston Ship Channel area
exhibited the warming trend since the onset of industrial activity.
Tropical North Atlantic SST has
exhibited a warming trend of ~ 0.3 °C over the last 100 years; whereas Atlantic hurricane activity has not exhibited trendlike variability, but rather distinct multidecadal cycles as documented here and elsewhere.
The sun, in contrast, has not
exhibited any warming trend over the past 50 years.
The UK's HadCRUT4 global empirical evidence makes it very clear: modern acceleration of warming temperatures is not unprecedented, nor unusual due to CO2 emissions; nor does the modern period
exhibit any warming trend that comes close to even 1.5 °C per century.
While the global effect is very limited, significant cooling is shown for Northern Europe, Northern Asia, and North America, with many other regions
exhibiting a warming trend.
Not exact matches
To explore the links between climatic
warming and rainfall in drylands, scientists from the Universities of Cardiff and Bristol analysed more than 50 years of detailed rainfall data (measured every minute) from a semi-arid drainage basin in south east Arizona
exhibiting an upward
trend in temperatures during that period.
In fact, the CRF curves presented by some of the key cosmic - ray hypothesis proponents, Marsh & Svensmark, do not
exhibit any
trend, yet it has been claimed that CRF is responsible for the most recent
warming (Marsh & Svensmark say that the wiggles correlate, but don't discuss the [or lack of] observed
trends).
Interglacial
trends over the past 400,000 years
exhibit steep
warming onsets, slower cooling rates and nearly flat plateaus.
I must admit that I don't understand how Svensmark can explain how GCR can explain the recent global
warming if there evidently is no
trend in the GCR (Even in his own papers, the GCR records have been plotted, and they do not
exhibit trend!).
The recent
warming has been more pronounced in the Arctic Eurasia than in many other regions on our planet, but Franzke (2012) argues that only one out of 109 temperature records from this region
exhibits a significant
warming trend.
I agree with others that consider this a pretty bold forecast by Keenlyside et al. since I think that 2005 - 2007 were
warmer than 1994 - 2004 requiring that 2008 - 2010
exhibit quite a steep cooling
trend for their forecast to pan out.
Teacher input: Because each weather station exists in a unique micro-climate, individual differences cause each station to
exhibit small cooling or
warming trends that might not be seen at the other stations.
Based on previously reported analysis of the observations and modelling studies this is neither inconsistent with a
warming planet nor unexpected; and computation of global temperature
trends over longer periods does
exhibit statistically significant
warming.
In addition, Western Russia
exhibits greater
warming in the
trend regressions than the scaled - interannual regressions, with maximum values around 3 — 4 °C compared to 2 — 3 °C.
The overview (and amended news release) now read: «Data collected by weather satellites since 1979 continue to
exhibit some evidence of lower atmospheric
warming, with estimated
trends ranging near the low end of past IPCC forecasts.»
The very first finding in the original news release for the ISPM (and the original version of ISPM overview) contains the following statement: «Data collected by weather satellites since 1979 continue to
exhibit little evidence of atmospheric
warming, with estimated
trends ranging from nearly zero to the low end of past IPCC forecasts.»
How much cooling would you estimate occurred in the sites that
exhibited a cooling
trend, if the average of all sites is +.65 C and the 2/3 of sites that showed a
warming trend were on average between +1 - 2C?
The UN's IPCC claim that large modern consumer / industrial CO2 emissions are causing maximum temperatures to increase across the globe proves to be without any empirical and scientific merit... NOAA's NCDC division documents U.S. maximum temperatures are
exhibiting a declining
trend, not catastrophic «global
warming»...
Needless to say, her servile puppet - scientists have performed that task since 2008, month - in and month - out, as the change in the global
warming trend exhibits (red is new
trend; blue is old) in the adjacent chart.
Other than a single datapoint (blue column), all the long - term temperature
trends for the left chart
exhibit warming greater than 1.5 degrees per century; in contrast, the majority of
trends (blue columns) for the right chart are below 1.5 degree per century, despite faster CO2 growth and the associated higher atmospheric CO2 levels.
Spatial
trend patterns differ for the
warm and cold extremes, with the
warm extremes showing continuous positive
trends across the globe and the cold extremes
exhibiting a coherent cooling pattern across the Northern Hemisphere mid-latitudes that has emerged in the recent 15 years and is not reproduced by the models.
While the M10 dataset
exhibits a larger spring
warming trend on WAIS than the other datasets, the spatial pattern and magnitudes of
trends closely match those of the READER station data (Fig. 3) where overlap occurs.
Finds that TX90pct and TN90pct
trends are larger and
exhibit more significance for
warm spells, implying that non-summer events are driving annual
trends over some regions
This sudden spike, he said, does not fit well with a greenhouse
warming theory that would likely
exhibit a smoother
trend.
Spring and Autumn
exhibit much more significant recent
warming trends, which might lead us to imagine that they could represent «extremes».
It was found that each new version of GAST has nearly always
exhibited a steeper
warming linear
trend over its entire history.
For 900 years, this series
exhibits multi-decadal fluctuations with amplitudes up to 0.3 °C superimposed on a negative
trend of 0.15 °C, followed by an abrupt
warming (~ 0.4 °C) matching that observed in the instrumental data during the first half of the 20th century.
