In Southern Europe, climate change is projected to worsen conditions (high temperatures and drought) in a region already vulnerable to climate variability, and to reduce water availability, hydropower potential, summer tourism and, in general, crop productivity.

''... 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.»

Based on temperature records from 1864 to 2002, the odds of such a heatwave occurring are about 1 in 10 million.4 An event like the 2003 heatwave becomes much more likely after factoring in the observed warming of 2 °F over Europe and increased weather variability.5 In addition, comparing computer models of climate with and without human contribution shows that human influence has roughly quadrupled the odds of a European summer as hot as or hotter than the summer of 2003.6

Here we show that due to the small temperature variability from one year to another, the earliest emergence of significant warming occurs in the summer season in low latitude countries (≈ 25 ° S — 25 ° N).

Most agree it's difficult to determine exactly what is driving late summer temperatures in the tropical Atlantic — be it natural climate variability, greenhouse gases or some other factor, such as volcanic eruptions.

What the paper does focus on, Hansen said, is determining whether extreme weather events like the Texas heat wave can be attributed to climate variability — the natural ups and downs in seasonal temperature — or to the global upward trend in summer temperatures that science now links with climate change.

The role of increasing temperature variability in European summer heat waves.

Not to dwell too much on semantics (on what smooth and gradual exactly means in the context of a hardly constant weather), as far as temperatures over Europe are concerned, my understanding is that night time winter temperatures will rise most, and summer maximum temperatures least and that otherwise the variability of temperature won't be affected much.

Interannual variability of surface temperature is larger in the winter hemisphere than in the summer and larger over land than over ocean (Fig. 2).
