In contrast, the only interval in the GISS or NCDC global time series that looks odd is during the WWII years between 1941 and 1945, where it appears that all the temperatures have a warming bias of 0.1 C. I agree with J.J.Kennedy that it is an artificial shift based on war - time procedures, but I think the corrections that Hadley made post-WWII were questionable.

In that span, the amount of CO2 in the air fluctuated between 190 and 280 parts per million — low during ice ages and high during warm intervals.

Thus one might expect larger hurricanes to extend the interval between hurricanes over the patches of ocean that spawn them, because they don't spawn until the sea surface warms sufficiently again.

For instance, Dr. Zycher correctly notes that 1998 and 2015 were / will be warm years due to the effect of El Niño, but incorrectly surmises that temperatures remained flat between these two time intervals (c.f. Fig. 2).

Research indicates that the Arctic had substantially less sea ice during this period compared to present Current desert regions of Central Asia were extensively forested due to higher rainfall, and the warm temperate forest belts in China and Japan were extended northwards West African sediments additionally record the «African Humid Period», an interval between 16,000 and 6,000 years ago when Africa was much wetter due to a strengthening of the African monsoon While there do not appear to have been significant temperature changes at most low latitude sites, other climate changes have been reported.

17 El Nino verses La Nina El Niño La Niña Trade winds weaken Warm ocean water replaces offshore cold water near South America Irregular intervals of three to seven years Wetter than average winters in NC La Niña Normal conditions between El Nino events When surface temperatures in the eastern Pacific are colder than average The southern US is usually warmer and dryer in climate

''... worked with two sediment cores they extracted from the seabed of the eastern Norwegian Sea, developing a 1000 - year proxy temperature record «based on measurements of δ18O in Neogloboquadrina pachyderma, a planktonic foraminifer that calcifies at relatively shallow depths within the Atlantic waters of the eastern Norwegian Sea during late summer,» which they compared with the temporal histories of various proxies of concomitant solar activity... This work revealed, as the seven scientists describe it, that «the lowest isotope values (highest temperatures) of the last millennium are seen ~ 1100 - 1300 A.D., during the Medieval Climate Anomaly, and again after ~ 1950 A.D.» In between these two warm intervals, of course, were the colder temperatures of the Little Ice Age, when oscillatory thermal minima occurred at the times of the Dalton, Maunder, Sporer and Wolf solar minima, such that the δ18O proxy record of near - surface water temperature was found to be «robustly and near - synchronously correlated with various proxies of solar variability spanning the last millennium,» with decade - to century - scale temperature variability of 1 to 2 °C magnitude.»

There were no globally synchronous multi-decadal warm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between AD 1580 and 1880, punctuated in some regions by warm decades during the eighteenth centwarm or cold intervals that define a worldwide Medieval Warm Period or Little Ice Age, but all reconstructions show generally cold conditions between AD 1580 and 1880, punctuated in some regions by warm decades during the eighteenth centWarm Period or Little Ice Age, but all reconstructions show generally cold conditions between AD 1580 and 1880, punctuated in some regions by warm decades during the eighteenth centwarm decades during the eighteenth century.

The authors claim to have largely resolved the «divergence problem» through judicious application of RCS, and in doing so find broad agreement between the instrumental and proxy record during the «entire 20th century warming interval», as stated in the abstract.

If, on the other hand, the differences between station means and station offsets show large variance because different stations have warmed differently between baseline and observation intervals, then the last term will greatly increase the estimated data variance.

These salinity shifts correspond well in timing to the OHC shifts, which are also coincident with surface transitions from global - warming slowdown to rapid warming and then to the current slowdown, with intervals between shifts lasting about three decades.

Second, there are presently only very few millennial length records available for direct comparison between the recent period and the MWP, and these records show trends which are not necessarily coherent over the latter interval, resulting in a «'' flattening» of MWP conditions compared to recent warming in our reconstruction.

«At all sites and during warm as well as cold climatic intervals SST values are well above 0 °C (i.e., ranging between about 5 and 12 °C), suggesting that the SST data represent more the summer situation with ice - free conditions.»

The most recent interval in which sustained global temperatures exceeded those of today was during the Pliocene epoch (2.6 — 5.3 Ma), when global surface temperatures were between 2 and 3 °C warmer than present (Dowsett, 2007).
