Castro S. L., W. J. Emery, G. A. Wick and W. Tandy (October 2017): Submesoscale
Sea Surface Temperature Variability from UAV and Satellite Measurements.
The simulated
sea surface temperature variability from two global coupled climate models for the second half of the 20th century is dominated by natural internal variability associated with the Antarctic Oscillation, suggesting that the models» internal variability is too strong, leading to a response to anthropogenic forcing that is too weak.

In recent years, a brand of research called «climate attribution science» has sprouted
from this question, examining the impact of extreme events to determine how much — often in fractional terms — is related to human - induced climate change, and how much to natural
variability (whether in climate patterns such as the El Niño / La Niña - Southern Oscillation,
sea -
surface temperatures, changes in incoming solar radiation, or a host of other possible factors).

''... 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.»
