Egypt’s Nile delta, only ~1 m above mean sea level at the Mediterranean coast, is subject to uneven rates of submergence. This is a response to several factors leading to increasing land lowering (subsidence) of the northern delta and adjacent seafloor, plus an accelerating rise in eustatic (world) sea level in the Mediterranean. An average eustatic sea-level rise of ~3 mm/yr represents only ~26% to 45% of total relative sea-level rise measured along this margin.

Coastal flooding in the Yucatan Peninsula is mainly associated with storm surge events triggered by high-pressure cold fronts systems passing through the Gulf of Mexico. To assess coastal flood hazards, this study uses a thirty-year water level hindcast, and considers the contribution of wave setup and the role of tidal hydrodynamics. To diagnose the mechanisms controlling the water levels, extreme sea level occurrence probability at Progreso Port was performed to identify the two worst storms in terms of maximum residual tide (Event A), and maximum water level (Event B).

This annual statement confirms that 2016 was the warmest year on record, approximately 1.1 °C above the pre-industrial period, and 0.06 °C above the previous highest value set in 2015. Noteworthy extreme events in 2016 included severe droughts that brought food insecurity to millions in southern and eastern Africa and Central America.

The record-breaking heat that made 2016 the hottest year ever recorded has continued into 2017, pushing the world into “truly uncharted territory”, said WMO in its annual statement on the State of the Global Climate ahead of the World Meteorological Day

Tropical cyclones and sea level rise cause major problems including beach erosion and damage to infrastructure in coastal areas. Inexpensive but effective plans for coastal protection will be needed by small island nations and developing countries. Natural breakwater formed by reefs is more cost-effective in coastal protection than the construction of artificial defenses. It provides a habitat for marine organisms and societal benefits including marine products, tourism, and education.

Without major efforts to rebuild Louisiana’s wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of se

Future extreme sea levels (ESLs) and flood risk along European coasts will be strongly impacted by global warming. Yet, comprehensive projections of ESL that include mean sea level (MSL), tides, waves, and storm surges do not exist. Here, we show changes in all components of ESLs until 2100 in view of climate change. We find that by the end of this century, the 100-year ESL along Europe's coastlines is on average projected to increase by 57 cm for Representative Concentration Pathways (RCP)4.5 and 81 cm for RCP8.5.

Mangrove plantation belts are expected to act as natural infrastructural buffers against coastal hazards. However, their performance will not endure over time if the platform is not appropriately designed. In fact, despite massive funds dedicated to the rehabilitation of mangrove forests, the long-term survival rates of mangroves are generally low. This paper investigates the function of mangrove embankments in attenuating the amplitudes of ocean tides through a coupled numerical model that reproduces shallow-water wave propagations under the progress of soil consolidation.

Global profits from fishing could grow by tens of billions of dollars if depleted fish stocks were allowed to recover, bolstering the livelihoods of millions of people and feeding the world’s growing population, says this new study by the World Bank.

Sea-level rise is a global problem, yet to forecast future changes, we must understand how and why relative sea level (RSL) varied in the past, on local to global scales. In East and Southeast Asia, details of Holocene RSL are poorly understood. Here we present two independent high-resolution RSL proxy records from Belitung Island on the Sunda Shelf.
