Cooling Center
A cooling center is an air-conditioned public space set up by local authorities to temporarily deal with the health effects of extreme heat weather conditions, like the ones caused by heat waves. Cooling centers are meant to prevent hyperthermia caused by heat, humidity, and poor air quality. Cooling centers provide shade, water, and restrooms; medical attention and referrals to social services may also be offered. Their services are aimed at the homeless, those without access to adequate air conditioning and at-risk populations such as the elderly, children and those with mental disability or chronic medical conditions. As the danger of heat waves has risen in the public consciousness, cooling centers are increasingly used in larger cities such as Los Angeles, New York City, Chicago, Boston, and Toronto, as well as less urban population areas. Cooling centers may also be used in places like Portland and Seattle where home air conditioning is rare but summer can bring temperature ...

Air Conditioning
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat from an enclosed space to achieve a more comfortable interior environment (sometimes referred to as 'comfort cooling') and in some cases also strictly controlling the humidity of internal air. Air conditioning can be achieved using a mechanical 'air conditioner' or alternatively a variety of other methods, including passive cooling or ventilative cooling. Air conditioning is a member of a family of systems and techniques that provide heating, ventilation, and air conditioning (HVAC). Heat pumps are similar in many ways to air conditioners, but use a reversing valve to allow them to both heat and also cool an enclosed space. Air conditioners, which typically use vapor-compression refrigeration, range in size from small units used within vehicles or single rooms to massive units that can cool large buildings. Air source heat pumps, which can be used for heating as well as cooling, are becoming incre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reuters
Reuters ( ) is a news agency owned by Thomson Reuters Corporation. It employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Reuters is one of the largest news agencies in the world. The agency was established in London in 1851 by the German-born Paul Reuter. It was acquired by the Thomson Corporation of Canada in 2008 and now makes up the media division of Thomson Reuters. History 19th century Paul Reuter worked at a book-publishing firm in Berlin and was involved in distributing radical pamphlets at the beginning of the Revolutions in 1848. These publications brought much attention to Reuter, who in 1850 developed a prototype news service in Aachen using homing pigeons and electric telegraphy from 1851 on, in order to transmit messages between Brussels and Aachen, in what today is Aachen's Reuters House. Reuter moved to London in 1851 and established a news wire agency at the London Royal Exchange. Headquartered in London, Reuter' ...

Heat Waves
A heat wave, or heatwave, is a period of excessively hot weather, which may be accompanied by high humidity, especially in oceanic climate countries. While definitions vary, a heat wave is usually measured relative to the usual climate in the area and relative to normal temperatures for the season. Temperatures that people from a hotter climate consider normal can be called a heat wave in a cooler area if they are outside the normal climate pattern for that area. The term is applied both to hot weather variations and to extraordinary spells of hot weather which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, increased risk of wildfires in areas with drought, and widespread power outages due to increased use of air conditioning. A heat wave is considered extreme weather, and poses danger to human health because heat and sunlight overwhelm the human body's cooling system. Heat waves can usually be ...

Warming Center
A warming center (also a heat bank or warm bank) is a short-term emergency shelter that operates when temperatures or a combination of precipitation, wind chill, wind and temperature become dangerously inclement. Their paramount purpose is the prevention of death and injury from exposure to the elements. This may include acute trauma from falling objects such as trees, or injury to extremities due to frostbite. A more prevalent emergency which warming centers seek to prevent is hypothermia, the risk for which is aggravated by factors such as age, alcohol consumption, and homelessness. Purpose Thus warming centers are frequently directed to the circumstances of persons who are ''unsheltered'' due to a personal state of homelessness and who, for one reason or another, do not utilize existing homeless shelters. In other circumstances, centers serve stranded motorists or, during cold-weather power outages, homeowners and tenants. In some cases, when cold snaps threaten wildlife, ...

Warning System
Warning system is any system of biological or technical nature deployed by an individual or group to inform of a future danger. Its purpose is to enable the deployer of the warning system to prepare for the danger and act accordingly to mitigate or avoid it. Warnings cannot be effective unless people react to them. People are more likely to ignore a system that regularly produces false warnings (the cry-wolf effect), but reducing the number of false warnings generally also increases the risk of not giving a warning when it is needed. Some warnings are non-specific: for instance, the probability of an earthquake of a certain magnitude in a certain area over the next decade. Such warnings cannot be used to guide short-term precautions such as evacuation. Opportunities to take long-term precautions, such as better building codes and disaster preparedness, may be ignored.
