چکیده

We assess the relationship between temperature and global sea-level (GSL) variability over the Common Era through a statistical metaanalysis of proxy relative sea-level reconstructions and tide-gauge data. GSL rose at 0.1 ± 0.1 mm/y (2σ) over 0-700 CE. A GSL fall of 0.2 ± 0.2 mm/y over 1000-1400 CE is associated with ∼ 0.2 °C global mean cooling. A significant GSL acceleration began in the 19th century and yielded a 20th century rise that is extremely likely (probability [Formula: see text]) faster than during any of the previous 27 centuries. A semiempirical model calibrated against the GSL reconstruction indicates that, in the absence of anthropogenic climate change, it is extremely likely ([Formula: see text]) that 20th century GSL would have risen by less than 51% of the observed [Formula: see text] cm. The new semiempirical model largely reconciles previous differences between semiempirical 21st century GSL projections and the process model-based projections summarized in the Intergovernmental Panel on Climate Change's Fifth Assessment Report.

بررسی اثر تغییر اقلیم بر روند نمایه های حدی بارش ایران زمین

Global changes in extremes of the climatic variables that have been observed in recent decades can only be accounted anthropogenic, as well as natural changes. Factors are considered, and under enhanced greenhouse gas forcing the frequency of some of these extreme events is likely to change (IPCC, 2007 Alexander et al., 2007). Folland et al. (2001) showed that in some regions both temperature a...

The Relation among Sea Ice, Surface Temperature, and Atmospheric Circulation in Simulations of Future Climate

Observations document substantial 20-40 year trends in the past several decades in the Arctic. Studies show sea ice thickness and extent have declined, air temperature has increased, and the temperature and salinity of the upper ocean have increased (e.g., see Serreze et al., 2000). At the same time, we have seen a weakening of the tropospheric anticyclone over the Beaufort Sea that can be asso...

Relationships between rainfall in the southwest of Western Australia and near-global patterns of sea-surface temperature and mean sea-level pressure variability

A statistically significant decrease in rainfall in southwest Western Australia (SWWA), since the middle of last century, has been reported in a number of studies (Wright 1974a, b; Pittock 1983; Nicholls and Lavery 1992; Yu and Neil 1993; Hennessy et al. 1999 and IOCI 2002). This decrease in rainfall not only affects economic activities in Western Australia, but a lack of understanding of mecha...
