Natural disasters are often frightening and difficult for us to understand, because we have no control over when and where they happen. What we can control is how prepared we are as communities and governments to deal with the dangers that natural disasters bring.
Places that are more likely to have natural disasters, such as the earthquake-prone Pacific Ring of Fire, or coastal areas vulnerable to hurricanes, require accurate methods of predicting disasters and warning the public quickly. Once the people have been informed, evacuation routes must be provided so that they can all leave quickly and safely, even if they travel by foot. Emergency warnings and evacuation plans are not enough, though. Where there is a high risk of earthquakes, buildings need to be strong and flexible enough to survive a quake without collapsing. Where hurricanes and flooding are a problem, levees and dams must be strong enough to hold floodwaters, and natural drainage systems must be maintained to allow waters to flow back into the ocean. The failure of the levee and drainage systems was responsible for most of the destruction and flooding in New Orleans after Hurricane Katrina in 2005. It was the poor planning of evacuation routes and assistance for those trapped by the flooding that resulted in the many tragic fatalities.
People need to be educated on the risks in their area, and what to do when a disaster strikes. After a disaster, even if no one has died, there is a lot of damage to people' homes, farms and workplaces that must be repaired. This takes a lot of time and money to fix, and a country damaged by a disaster usually needs a large amount of international help to get better. Donated food, clothing, medicine and experienced professionals are all important when there is a disaster, but when the emergency is over it can take years to rebuild and make sure that future disasters can be managed. The boxing-day tsunami which devastated Indonesia and the 2005 earthquake in Kashmir, Pakistan were both natural disasters whose effects were made worse by underdeveloped infrastructure and widespread poverty. Tsunamis, earthquakes, hurricanes or any other natural disaster can't be avoided, but with good preparation and well-organized help after the fact, it is possible to survive and go back to normal life afterwards.
Global dimming, a gradual reduction in the amount of global direct irradiance at the Earth's surface, has partially counteracted global warming from 1960 to the present. The main cause of this dimming is aerosols produced by volcanoes and pollutants. These aerosols exert a cooling effect by increasing the reflection of incoming sunlight. James Hansen and colleagues have proposed that the effects of the products of fossil fuel combustion—CO2 and aerosols—have largely offset one another in recent decades, so that net warming has been driven mainly by non-CO2 greenhouse gases.
In addition to their direct effect by scattering and absorbing solar radiation, aerosols have indirect effects on the radiation budget. Sulfate aerosols act as cloud condensation nuclei and thus lead to clouds that have more and smaller cloud droplets. These clouds reflect solar radiation more efficiently than clouds with fewer and larger droplets. This effect also causes droplets to be of more uniform size, which reduces growth of raindrops and makes the cloud more reflective to incoming sunlight.
Soot may cool or warm, depending on whether it is airborne or deposited. Atmospheric soot aerosols directly absorb solar radiation, which heats the atmosphere and cools the surface. Regionally (but not globally), as much as 50% of surface warming due to greenhouse gases may be masked by atmospheric brown clouds. When deposited, especially on glaciers or on ice in arctic regions, the lower surface albedo can also directly heat the surface. The influences of aerosols, including black carbon, are most pronounced in the tropics and sub-tropics, particularly in Asia, while the effects of greenhouse gases are dominant in the extratropics and southern hemisphere.. I hope it can help . . . ..
Has anyone read the republcan's road to disaster?
What do you mean?
We lived it and barely survived...
God help us if there's a repeat.
What is the highest amount of natural diasters in one year?
Cyclones, earthquakes and hurricanes around the world made 2008 one of the worst years for natural disasters in modern day history.
At least 235,816 people were killed in 321 different disasters, some of the worst of which took place in Burma and China, according to the UN International Strategy for Disaster Reduction. The UN estimates that nearly 84,000 people died and 54,000 went missing after Cyclone Nargis came crashing into Burma, also known as Myanmar, on May 3. About 2.5 million people were left destitute by the storm. Less than two weeks later, nearly 70,000 people were killed when an earthquake rocked a swath of central and southern China. An estimated five million people were rendered homeless.
The 2008 Atlantic hurricane season produced a record number of consecutive storms that struck the United States and ranked as one of the more active seasons in the 64 years since comprehensive records started to be kept, according to the U.S. National Oceanic and Atmospheric Administration.
The world's disasters in 2008 caused estimated damage of $227 billion, some 60 per cent of it — or $136 billion — in China. Hurricane Ike, which hit the Caribbean and the southern United States in September, also substantially contributed to the cost with an estimated $30 billion in damage, the UN agency said.
I hope this helps you.
