Thus the high rate of increase is almost totally irrelevant to the behavior of
temperature over the same period.
Of course, DS can (and should already have) calculated the change in insolation at the northern spring equinox over the last thousand (or two thousand) years, and plotted it against changes in
temperature over the same period.
The regions of moisture increase are associated with regions of rising
temperatures over the same period, and the regions of decreased moisture are associated with falling temperatures.
Now there were two papers put out by a Swiss team (you should know who) on consideration of European warming where they argued that natural effects could be ruled out; the first paper argued for strong water vapour feedback causing the 1980 to 1998 temperature rise and the later paper, using exactly the same data, argued for a reduction in aerosols causing a recovery in
temperatures over the same period.

Why not, using the
same scaling, show the
temperature changes from 1910 to 1945 and from 1945 to 1975 against the CO2 and Sun change
over those
periods and try and explain why that would show next to no relationship on that scaling?

The
temperature anomaly on Earth
over the
same period is about 10 times larger, hence the suggestion that IF the ACRIM inferred changes in the mean insolation are correct, then the inferred increase in solar radiance would account for about 10 % of the

This was my mental equation dF = dH / dt + lambda * dT where dF is the forcing change
over a given
period (1955 - 2010), dH / dt is the rate of change of ocean heat content, and dT is the surface
temperature change in the
same period, with lambda being the equilibrium sensitivity parameter, so the last term is the Planck response to balance the forcing in the absence of ocean storage changes.
The reconstruction also «reveals a long - term cooling trend of -0.31 °C per 1,000 years (± 0:03 °C)
over the 138 B.C. - A.D. 1900

same temperature - sensitive trees.»

temperature and total ice in Antarctica
over the
same period, both transported in.
During that
same period, average annual rainfall in New South Wales declined by 3.6 inches (92 millimeters).3 Scientists think the decline in autumn rainfall in southeast Australia since the late 1950s may be partly due to increases in heat - trapping gases in Earth's atmosphere.3, 14 Major bushfires
over southeast Australia are linked to the positive phase of an ocean cycle called the «Indian Ocean Dipole» — when sea surface
temperatures are warmer than average in the western Indian Ocean, likely in response to global warming.15, 16
It is currently suspected, for example, that the recent increase in deep - ocean heat content is driven by geothermal sources rather than atmospheric (which would solve the «paradox» that shallow ocean
temperatures,
over the
same period, have fallen slightly).
Almost any average
temperature you wish depending on how you slice it and none of it has meaning except in the case that you slice it exactly the
same way
over successive measurements

Further, there is firm evidence that migration of CO2 isn't important in the Vostok and Dome C ice cores
over the past 800,000 years: each glacial / interglacial

Over the
same period, the globally and annually averaged land and sea surface
temperature (HadCRUT3) increased by 0.7 °C.
The fact this is seemingly not fully recognized — or here integrated — by Curry goes to the
same reason Curry does not recognize why the so called «pause» is a fiction, why the «slowing» of the «rate» of increase in average ambient global land and ocean surface air
temperatures over a shorter term
period from the larger spike beyond the longer term mean of the 90s is also meaningless in terms of the basic issue, and why the average ambient increase in global air
temperatures over such a short term is by far the least important empirical indicia of the issue.
By contrast, air
temperatures over the Antarctic region for the
same period were above average in some areas, such as the Antarctic Peninsula and near the pole, but below average in others.

Firstly, that the statistical distribution of the observed 15 - year global
temperature trends since 1880 isn't distinguishable from the distribution of 15 - year global
temperature trends derived from an ensemble of model simulations, and, secondly, whether simulated global
temperature trends
over 15 years since 1950 lie in the
same tail of the statistical distribution as the observed 15 - year
temperature trends or whether the simulated and observed trends lie in opposite tails of the distribution largely depends on whether the simulated and observed ENSO variablity
over the 15 - year
periods are in phase or out of phase by chance.
Over this
same period Global
temperature increased by 0.54 °C and Atmospheric CO2 increased by 66 ppmv or 20 %
The

periods, e.g. 20 years, have a frequency distribution, too.
The observational facts are; Solar activity has decreased slightly
over the
same period temperatures have levelled off.
You may wonder why the government finds the need to pursue such action since 1) U.S. carbon dioxide emissions have already topped out and have generally been on the decline for the past 7 - 8 years or so (from technological advances in natural gas extraction and a slow economy more so than from already - enacted government regulations and subsidies); 2) greenhouse gases from the rest of the world (primarily driven by China) have been sky - rocketing
over the
same period, which lessens any impacts that our emissions reduction have); and 3) even in their totality, U.S. carbon dioxide emissions have a negligible influence on local / regional / global climate change (even a immediate and permanent cessation of all our carbon dioxide emissions would likely result in a mitigation of global
temperature rise of less than one - quarter of a degree C by the end of the century).
Mann re-iterated that the MBH reconstruction had the
same amplitude as the increase in
temperature over the calibration
period and ignored the flattening out in the proxies that was worrying Severinghaus.

temperature anomaly
over the
same period:
California's record warmest year occurs at the peak of a sustained, long - term warming trend in the state
