How Did The La Niña Change

The flood of 1997 started with a wetter the normal fall then ground froze early that year which made it easier to freeze all the liquid. When all the snow melted the water was released onto the surface and it made it easy for the flood to happen. When the climate changed is when all the flooding occurred. After the red river along the north dakota and minnesota was flooded it started to flood more often and continue to happen. The flooding of 1997 wrecked houses and old buildings it made it hard to drive and to get from here to there. The pastures were wrecked making it hard for animals to get around because all of the mucky fields which was making the animals sick.

The tendency towards more intense precipitation events is projected to the future. The more precipitation, the more risk of flooding.More heavy downpours may increase the likelihood of property damage, travel delays and disruption in

The floods were caused by heavy rain from a tropical cyclone named cyclone Tasha that joined with a La Niña event* caused an overflow of water in rivers and lakes. The La Niña in 2010 was the strongest La Niña since 1973.This caused a lot of rainfall across Queensland. That December was the wettest on record and 107 places had their highest rainfalls ever. 2010 was also recorded as the states most wet spring since the 1900’s and Australia's third wettest year. Floods started across the state in December. On the 28th December a monsoonal trough crossed the coast from the Coral Sea, bringing heavy rain from the Gulf of Carpentaria to the Gold Coast, overfilling a dam in Towoomba, causing it to malfunction and release the water.

Floods are common natural disasters that occur all over the world. Flooding has devastating impacts on the lives of people who are affected by the disaster. Floods can ruin crops, demolish homes, take innocent lives and cause many other types of hardships. These disasters can also leave people with a financial burden and emotional effects. Studies have shown that floods have led to various sickness and health complications. This common disaster has recently taken place in the state of Louisiana. Louisiana has been suffering from an enormous flood and has left people without homes, without food, and without personal belongings.

During the spring and early summers of 2011 and 2014, the Assiniboine River Basin (ARB) in Southern Saskatchewan and Manitoba experienced extreme flood conditions with prolonged duration and severity. This persistence and shortened interval between disasters caused concerns about the impacts of climate change in the region (Brimelow, 2015). The interactions between the Atmosphere, Geosphere, Hydrosphere, and lastly Biosphere all contributed to the events that took place during the specified flood years. I will look to address the intertwined relationship between these four spheres, and conclude with possible mitigation strategies that provinces and municipalities are likely to invest in as anthropogenic change is inevitably shortening the

In 1987 an atmospheric river heated Los Angeles ,the consecutive rain for more than 5 days made this the largest Flood that had happen in Los Angeles. This is best know as the California Great Flood. Houses, infrastructure, landfill were under water and hundreds of people die. This Flood has been the most expensive flood recorder in Los Angeles history. Billions of dollars were the total sum of losses left by the Flood as a result the entire state of california was declared in bankruptcy. Los angeles is not a place where hurricanes are generated due to its location but it is affected by El nino and atmospheric rivers that year after year are increasing its power. Is a vulnerable city where flood can occur at anytime , due to it topography

Climate change was blamed for risen in temperature by half a degree, producing more vapor which results in heavy rainfall in 2010 in Brisbane. The Burnett River and Fitzroy River were exceedingly bad hit on 28th and 29th December 2010, when the stream level rose to more than eighteen meters. Author was discussed that flooding proceeded into January 2011, turning out to be more terrible in Brisbane and damages came around 2.38 billion AUS dollars. Flood again hit the area in 2013 (Davies 2013).

Plate tectonics move land masses around, and occasionally, interactions between different plates causes new land to form, and can even join two separate continents together, changing ocean currents and causing climate change. This is evident in the collision of the North and South American continents, which created the Isthmus of Panama, and separated the Pacific and Atlantic Ocean. Approximately 15 million years ago, the North and South American continent was cut off from each other by a seaway about 200 km wide. Over time, the South American plate collided with the Caribbean and Cocos plate, and gradually closed the exchange of the Caribbean and Pacific waters 3-4 million years ago. This resulted in several consequences.

The floods started at the end of November 2010 and Cyclone Tasha a category 1 cyclone hit on Christmas Eve; they continued through till mid-January 2011. Cyclone Yasi then hit in February soon after the floods causing even more havoc to the already damaged Queensland.

Nobody knows when floods happen. These are natural disasters that can just strike when we least expect it. We may live in deserts or atop a mountain and still experience flooding.

Globle warming is increasing the possibility of a droughts and floods. Australia has faced harsh droughts and floods before that have created issues for Australia’s agriculture, environment and urban waters. Victoria needs to be prepared for all circumstances and has a dependable and functional water system. By having a reliable water system, it allows people to feel safe to create new industries and businesses in

Brisbane was not new to flooding, as the banks had broken before in 1974. The main cause this time around was Cyclone Tasha, a tropical storm which hit the area, combined with the La Niña, a phenomenon where wet weather comes to Australia every year. There was a sharp increase in rainfall, heavier than any year since 1973, and by December 2010 the weather was the wettest on record. The average rainfall was measured at 8.25 inches. Climate change was also blamed, as the temperature of the ocean surrounding Australia was said to have risen by half a degree, producing more vapour.

Queensland has experienced many economic impacts due to the flooding in 2010-2011. The floods will have a serious significant impact on the Australian economy. Queensland has a share of 20% on Australia’s economy. It also has 60% of global coking coal exports. Queensland with 28% of fruit and vegetable production gone. Due to the crisis of the Queensland flooding Australia is forecasted to 2.6% GDP rise in 2010-2011. With 4.7% unemployment in Queensland and an enormous sum of money such as $10 billion are being contributed to re-constructions.

2. How do we know climate in the past has changed, and what those changes were?

Year after year, increased carbon dioxide output is contributing to an increase in Earth’s climate. Carbon dioxide is the main greenhouse gas causing climate change, but many people forget that there are other ones which can amplify the effect of carbon dioxide many times over. In fact, water vapor itself is the most abundant greenhouse gas, and it can increase the amount of warming from carbon dioxide twice over. I want to know how data collected from NASA satellites about the El Niño weather phenomenon and its effect on water vapor in the environment can help to understand long-term trends in Earth’s climate.
