Climate Change In Tuvalu
Climate change is particularly threatening for the long-term habitability of the island country of Tuvalu, which has a land area of only and an average elevation of less than above sea level, with the highest point of Niulakita being about above sea level. Potential threats to the country due to climate change include rising sea levels, increasingly severe tropical cyclones, high temperatures, and drought. King tides (Perigean spring tide) can combine with storm surges and the rising sea level to inundate the low lying atolls. Tuvalu is widely considered one of the first countries likely to be significantly impacted by rising sea levels due to global climate change. According to some estimates, the highest tides could regularly flood 50% of the land area of national capital Funafuti by the mid-21st century, and 95% by 2100. The rising saltwater table could also destroy deep rooted food crops such as coconut, pulaka, and taro before they're overtaken by actual flooding. Meanwhi ...

Saltwater Intrusion
Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences. Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and seawater. Because saline water has a higher mineral content than freshwater, it is denser and has a higher water pressure. As a result, saltwater can push inland beneath the freshwater. In other topologies, submarine groundwater discharge can push fresh water into saltwater. Certain human activities, especially groundwater pumping from coastal freshwater wells, have increased saltwater intrusion in many coastal areas. Water extraction drops the level of fresh groundwater, reducing its water pressure and allowing saltwater to flow further inland. Other contributors to saltwater intrusion include navigation channels or agricultural and drainage channels, which provide conduits for ...

United Nations Framework Convention On Climate Change
The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany. The convention's main objective is explained in Article 2. It is the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic .e., human-causedinterference with the climate system". The treaty calls for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intended Nationally Determined Contributions
The nationally determined contributions (NDCs) are commitments that countries make to reduce their greenhouse gas emissions as part of climate change mitigation. These commitments include the necessary policies and measures for achieving the global targets set out in the Paris Agreement. The Paris Agreement has a long-term temperature goal which is to keep the rise in global surface temperature to well below above pre-industrial levels. The treaty also states that preferably the limit of the increase should only be . To achieve this temperature goal, greenhouse gas emissions should be reduced as soon as, and by as much as, possible. To stay below 1.5°C of global warming, emissions need to be cut by roughly 50% by 2030. This figure takes into account each country's documented pledges or NDCs. NDCs embody efforts by each country to reduce national emissions and adapt to the impacts of climate change. The Paris Agreement requires each of the 195 Parties to prepare, communicate a ...

Temperature Bar Chart Pacific-Tuvalu--1901-2020--2021-07-13
Temperature is a physical quantity that quantitatively expresses the attribute of hotness or coldness. Temperature is measured with a thermometer. It reflects the average kinetic energy of the vibrating and colliding atoms making up a substance. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), with the third being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract e ...

Coastal Management
Coastal management is defence against flooding and erosion, and techniques that stop erosion to claim lands. Protection against rising sea levels in the 21st century is crucial, as sea level rise accelerates due to climate change. Changes in sea level damage beaches and coastal systems are expected to rise at an increasing rate, causing coastal sediments to be disturbed by tidal energy. Coastal zones occupy less than 15% of the Earth's land area, while they host more than 40% of the world population. Nearly 1.2 billion people live within of a coastline and of sea level, with an average density three times higher than the global average for population. With three-quarters of the world population expected to reside in the coastal zone by 2025, human activities originating from this small land area will impose heavy pressure on coasts. Coastal zones contain rich resources to produce goods and services and are home to most commercial and industrial activities. History Coastal ...

South Pacific Applied Geoscience Commission
The Pacific Islands Applied Geoscience Commission (SOPAC) was an inter-governmental regional organisation dedicated to providing services to promote sustainable development in the countries it serves. In 2010, its functions had been transferred to the Pacific Community (SPC) and the Pacific Regional Environment Programme (SPREP), thus ending SOPAC as a separate entity. Today, SOPAC is a division of the SPC with its main office in Suva, Fiji. History SOPAC was created by the conclusion of a 1990 multilateral treaty known as the Agreement establishing the South Pacific Applied Geoscience Commission. The treaty was concluded and signed on 10 October 1990 in Tarawa, Kiribati. It was signed by representatives of the governments of Australia, Cook Islands, Fiji, Guam, Federated States of Micronesia, Kiribati, Marshall Islands, New Zealand, Papua New Guinea, Solomon Islands, Tonga, Tuvalu, Vanuatu, and Western Samoa. Since SOPAC's foundation, American Samoa, France, French Polynesia, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
