Even if the clouds hypothetically were completely determined by GCR, one would expect to see deterioration of the correlation if viewed from above due to the presence of higher clouds not influenced by GCR.

Large changes in cosmic rays are documented in response to magnetic - field variations (the Laschamp event of about 40,000 years ago is especially prominent) with no corresponding change in climate, so any cosmic - ray influence on the climate must be very small (a weak correlation can be obscured by noise; a strong control is almost always visible «by eye,» and clearly is absent).

The overflows further north are (i) unlikely to have an influence on the temperatures in the «cold blob», and (ii) are largely independent of the AMOC in the open Atlantic — at least that is suggested by a model simulation of the Max Planck Institute for Meteorology in Hamburg, for which we show a correlation analysis in Fig. 2b in our paper.

Soon knew that the relevant data series for discussing the AO influence on Western Hudson Bay temperature (and by proxy, sea ice) was from Churchill and despite being reminded of the fact by the first set of reviewers, nonetheless continued to only show the AO connection to a site 1000 miles away, which had a much higher correlation without any discussion of whether this other data was at all relevant to Churchill or the bears nearby.

Furthermore, it was shown that removal of a positive serial correlation component from time series by pre-whitening resulted in a reduction in the magnitude of the existing trend; and the removal of a trend component from a time series as a first step prior to pre-whitening eliminates the influence of the trend on the serial correlation and does not seriously affect the estimate of the true AR (1).

Other studies show good correlation with ocean currents, which may or may not be influenced by solar variations.

Their sum must be conserved in this exchange, therefore a very high correlation is unavoidable over periods too short for the LOD to be influenced as strongly by other mechanisms.

A few other problems: - While there is an extremely good correlation between accumulated emissions and accumulation in the atmosphere, the correlation is less when one looks at the year by year increase, simply because temperature changes have a short term influence (about 4 ppmv/degr.C) on the increase rate, not on the trend!

The same jumping to (wrong) conclusions was made by others, comparing temperature trends with the variability of the year by year increase of CO2: these have a quite good correlation, as there is a short term response of CO2 increase speed to temperature changes, but a only a small influence of temperature on the CO2 trend itself.

They find large differences between the observed and model correlation structure that can be explained by accounting for the combined influences of anthropogenic and solar forcing and internal variability in the observations.

If sample size is not masking a significant correlation, the greater readability advantage in federal courts may be explained by the factors that depress the summary judgment success rate in state courts: more restrictive state summary judgment standards, the lack of state court resources compared with those in federal court, and state court judges» relative reluctance to grant summary judgment.111 Although greater readability could still influence the outcomes in some state cases, which would be consistent with the slight readability advantage in our sample, on the whole the anti-summary-judgment factors would reduce the potential readability effect on summary judgment outcome.

Because both background environmental stressors as part of the daily routine in the animal facility and social stressors afforded by the rats» social environment may have provided necessary HPA activation for maternal behavior to exert a modulatory influence, such a correlation is at best consistent with a possible role of maternal care, but it can not be taken as conclusive evidence for sufficiency.
