"... по мере потепления мирового климата Западно-Антарктический ледяной щит растает", - приводит слова Кларка пресс-служба Орегонского университета. Сейчас масса ледового щита такова, что оказывает заметное гравитационное воздействие на воды окружающего океана, притягивая их к себе... Согласно исследованию таяние массивного ледяного щита вызовет подъем придавленного им грунта, а земная ось вращения сместится примерно на полкилометра, что так же повлияет на уровень моря в различных регионах земли.

оригинал - The Sea-Level Fingerprint of West Antarctic Collapse

2009 Jerry X. Mitrovica, Natalya Gomez, Peter U. Clark
the collapse of the WAIS leads to a displacement of the south rotation pole of ~100 m × EEV toward the West Antarctic; this shift drives a sea-level rise in North America and the Indian Ocean and a fall over South America and Asia relative to the EEV

due to the rotation of the Earth around its axis, any surface mass displacement together with the solid Earth and geoidal deformations triggers a perturbation of the polar motion that in turn affects the redistributionof melt water in the oceans and ,hence, the mean sea surface height (Milne and Mitrovica, 1996; Kendall et al., 2005)

4.4 Rotational feedback

An important aspect of the gravitationally self-consistent solution of the SLE is the rotational feedback, which is a new feature in SELEN. The changes in the mass distribution of ice and water induce a shift in the position of the rotational axis (polar wander) that has an ellipsoidal form (e.g. Gomez et al., 2010b). The difference as shown in Fig. 9bis described by the spherical harmonics of degree 2
