Abstract. Past glacier fluctuations provide insight into glacier dynamics, climate change, and the contribution of glaciers to sea-level rise. Here, the length fluctuations since the 19th century of 18 local glaciers in West and South Greenland are presented, extending and updating the study by Weidick (1968). The studied glaciers all show an overall retreat with an average of 1.2 ± 0.2 km over the 20th century, indicating a general rise of the equilibrium line along the west coast of Greenland during the last century. The rate of retreat was largest in the first half of the 20th century.

The 19th century to the 20th century is a moment in which Muslims enter a new gate, the gate of renewal. This phase is often referred to as the century of modernism, a century where people are confronted with the fact that the West is far ahead of them. This situation made various responses emerging, various Islamic groups responded in different ways based on their Islamic nature. Some respond with accommodative stance and recognize that the people are indeed doomed and must follow the West in order to rise from the downturn. Others respond by rejecting anything coming from the West because they think it is outside of Islam. These circles believe Islam is the best and the people must return to the foundations of revelation, this circle is often called the revivalists. One of the figures who is an important figure in Islamic reform, Jamaluddin Al-Afghani, a reformer who has its own uniqueness, uniqueness, and mystery. Departing from the division of Islamic features above, Afghani occupies a unique position in responding to Western domination of Islam. On the one hand, Afghani is very moderate by accommodating ideas coming from the West, this is done to improve the decline of the ummah. On the other hand, however, Afghani appeared so loudly when it came to the question of nationality or on matters relating to Islam. As a result, Afghani traces his legs on two different sides, he is a modernist but also a fundamentalist.

Abstract Seagrass ecosystems are important contributors to mitigation of climate change, since they are responsible for large carbon sinks. However, there is limited knowledge regarding the importance of variability of carbon storage in various ecosystems. In this study, we estimated carbon storage in several structurally different seagrass meadows along the west coast of Thailand and determined whether degree of exposure, human disturbance, and meadow type influenced carbon storage within these meadows. Carbon content within the living vegetation was on average 3±2.7 Mg ha−1, whilst average storage of carbon in the sediment was 122±35.3 Mg ha−1. Meadow type and disturbance had a significant influence on total carbon storage in the ecosystem, while the degree of exposure of the bay did not show great differences. Uniform meadows had a higher average total carbon storage than mixed meadows (133±36.2 and 110±41.3 Mg ha−1, respectively). Undisturbed meadows had a higher average total carbon storage than disturbed ones (140±36.5 and 103±34.8 Mg ha−1, respectively). The results obtained contribute to our understanding of carbon storage on an ecosystem scale and can provide a baseline for proper management, conservation, and climate change studies in the region.
