Given sufficient atmospheric moisture and instability, it may cause large cloud clusters and rain. A mean sea level pressure chart shows the direct relationship between isobar spacing (pressure ...

Around 30 per cent of Singapore’s land area is less than 5m above mean sea level. According to the Republic’s third national climate change study published in 2024, mean sea levels could ...

In the process, Hardenberg gives us a richly detailed yet very accessible history of how over five centuries, the concept of measuring mean sea level was a painstaking process that advanced in ...

AHD Australian Height Datum in metres above tide gauge zero. Subtract this value from the observed sea level to reduce the reading to an AHD height. Please note that at some sites, tide gauge zero is ...

The study was supported by the National Research Foundation and the National Environment Agency (NEA) under the National Sea Level Programme funding initiative. Around 30 per cent of Singapore’s land ...

Projections based on this fusion approach suggest that under a low-emissions scenario, global mean sea levels are very likely to rise between 0.3 and 1.0 meters by 2100. The IPCC's likely range ...

Researchers have generated the first dataset of water flow beneath the entire Antarctic Ice Sheet, which will lead to more accurate projections of sea level rise. The findings are published in the ...

New research reveals that subtle shifts in land elevation can considerably increase or decrease the local impacts of sea level rise along coastlines. Even though these changes usually amount to ...

The DEFCON system was created by the US Armed Forces in the 1950s, during the Cold War. The system was designed to provide a clear and concise way of communicating the current level of military ...
