Sentences with phrase «global sea level fluctuations»

Nevertheless such variability induced by winds or currents may give a false impression of global sea level fluctuations in analyses of tide gauge data.

Not exact matches

Eelco Rohling of the UK National Oceanography Centre at the University of Southampton and colleagues reconstructed sea level fluctuations over the last 520,000 years and compared this to global climate and carbon dioxide levels data for the same period.

The IPCC's assessment of the literature, prior to our study, was that global sea - level fluctuations over the last 5 millennia were < ± 25 cm, and that there was no clear evidence of whether specific fluctuations seen in some regional sea level records reflected global changes.

The supposed stable configuration of geography, with relatively predictable climate patterns, coastlines and icepacks in familiar locations, and clear demarcations of territorial control on land are increasingly dubious assumptions as weather patterns change, sea levels rise and ice packs disintegrate while technological innovations, communications and global markets cause rapid fluctuations in the price in food and other essentials across boundaries.

Thus, the increase in the surface temperature at sea level caused by doubling of the present - day CO2 concentration in the atmosphere will be less than 0.01 °C, which is negligible in comparison with natural temporal fluctuations of global temperature.

Fluctuations in the mass of the Greenland and Antarctic ice sheets are of considerable societal importance as they impact directly on global sea levels: since 1901, ice losses from Antarctica and Greenland, alongside the melting of small glaciers and ice caps and thermal expansion of the oceans, have caused global sea levels to rise at an average rate of 1.7 mm / yr.

Likewise, «during the middle - Pliocene... we find sea level fluctuations of 20 - 40 metres associated with global temperature variations between today's temperature and +3 °C» (Hansen, Sato et al., 2013).
