Not exact matches

However, no linear correlation has yet been confirmed and it is unclear whether even small changes on the scale at the different times affect the risk of neurological morbidity.

They found that there is a negative correlation between cloud cover and sea surface temperature apparent on a long time scale — again suggesting a positive cloud - climate feedback in this region.

Timothy Patterson, professor of geology and director of the Ottawa - Carleton Geoscience Centre of Canada's Carleton University, says that «CO2 variations show little correlation with our planet's climate on long, medium and even short - time scales.»

Data is made up Data is ok but not related Data is related but not on the time scale Data is no good at Tromso but is ok at Honolulu Data is all fine but it correlation is spurious, because some woman found one

It is conjectured that this mechanism could be the explanation for the observed correlations between past climate variations and cosmic rays, modulated by either solar activity or supernova activity in the solar neighborhood on very long time scales.

Nevertheless, independent correlations between GCR flux variations and climate (on the time scale of days — Forbush events, and on geological time scales — due to galactic variations) do appear to exist.

Another way of stating the question is whether below normal multi-year ice fractions account for a persistence in ice extent anomalies on interannual time scales, or whether the ice pack is now back in a mode with no interannual correlation between extent anomalies (Bitz, personal communication).

The palaeo climate record is an important part of the skeptic argument against climate alarmism, specifically the absence of clear evidence of CO2 causation of warming and regulation of or correlation with temperature on all time scales.

http://illconsidered.blogspot.com/2006/04/historically-co2-never-causes.html 100 years of shift does not factor into the larger scale phenomena http://illconsidered.blogspot.com/2006/01/one-hundred-years-is-not-enough.html Until climatologists can properly make models that reflect the entire global history and take into account plate position and how high the plates ride, oceanic levels due to this and the position of oceans, overall insolation, overall daylength and its effects on average global temperature and factor in known carbon dioxide levels over that time period, then they will be unable to give any correlation between current carbon dioxide levels and global temperature.

NO correlation on geologic time scales (geocarb reconstructions), and on shorter time scales (ice core reconstructions) where there IS a correlation, it runs IN REVERSE — with CO2 level FOLLOWING temperature changes, UP AND DOWN, like a DOG ON A LEASon geologic time scales (geocarb reconstructions), and on shorter time scales (ice core reconstructions) where there IS a correlation, it runs IN REVERSE — with CO2 level FOLLOWING temperature changes, UP AND DOWN, like a DOG ON A LEASon shorter time scales (ice core reconstructions) where there IS a correlation, it runs IN REVERSE — with CO2 level FOLLOWING temperature changes, UP AND DOWN, like a DOG ON A LEASON A LEASH.

An analysis of the historical data suggests a strong correlation between the solar activity and the natural climate variations on centennial time - scales, such as the colder climate during the Maunder (about 1650 − 1700 AD) and Dalton (about 1800 − 1820 AD) minima as well as climate warming during the steady increase in solar activity in the first half of the twentieth - century (Siscoe 1978; Hoyt & Schatten 1997; Solomon et al. 2007; Gray et al. 2010).

CO2 variations show little correlation with our planet's climate on long, medium and even short time scales.

The correlations improved when the time intervals were viewed on decadal scales and the data filtered accordingly.

Although we can not establish a clear connection between SAA dynamics and global warming, the strong correlation between the former and global sea level supports the idea that global warming may be at least partly controlled by deep Earth processes triggering geomagnetic phenomena, such as the South Atlantic Anomaly, on a century time scale.

One explanation for a weak ENSO signature in the correlation may be that the OLR is expected to be sensitive to the cloud cover, which may dominate on the short time scales and that ENSO involves longitudinal shifts rather than latitudinal changes (See the Supplementary Material).

Observed records of Atlantic hurricane activity show some correlation, on multi-year time - scales, between local tropical Atlantic sea surface temperatures (SSTs) and the Power Dissipation Index (PDI)-- see for example Fig. 3 on this EPA Climate Indicators site.

Finds that, in the Atlantic, variability on time scales of a few years and more is strongly correlated with tropical Atlantic sea surface temperature, while in the western North Pacific, this correlation, while still present, is considerably weaker
