Natural Disasters

Global warming, it affects us all, while we are damaging the ozone layer, every day, without we noticing it, more harmful rays from the sun are penetrating the atmosphere and exposing us to future diseases. In a future, global l warming will cause more natural disasters and more often. Hurricanes Hurricanes are severe tropical cyclones (storms that revolve) that bring heavy rain and very strong winds that can cause a lot of damage. Hurricanes are created in the ocean far away from the coasts. They are created on sea surface by the Coriolis Effect (the moving of earth) in open waters in the oceans. They are mostly called Hurricanes, but in East China they are called Typhoons. Down by Australia and Africa, they are called tropical Cyclones. They have a few names, but their destruction power is the same. The earth is affected by them like by seasons. In North America, they hit the coasts at about from July to November. In 2004, about 8 or more hurricanes affected the earth. The famous Katrina was the hurricane that caused so much destruction to New Orleans; the city was completely destroyed. Ivan was the hurricane that went the farthest inland of all hurricanes. It went spinning until Alabama, then it slowed down and became a storm heading south and as soon as it reached water, it started again with all its strength. Hurricanes are devastating sources of massive destruction, but when they hit land, the start losing their force until they vanish. Hurricane Jeanne was also very devastating, maybe the most; it leaved 1.100 deaths In conclusion, hurricanes are terrible weapons of massive destruction, they can cause thousands of deaths in just days, not as many as a nuclear bomb, but thinking it is just a natural disaster caused by nature, is amazing how much it can destroy. Hurricanes are not the only natural disasters caused by global warming, now comes the tornadoes, Natural disaster.

Tornadoes

Storm producing rotational winds up to 300 mph, the highest of any weather on
earth. Normally a tornado will form from a funnel-shaped cloud and touch the
earth for only a few minutes. However, during that time the tornado can travel
up to 70 mph, and leave a path of total destruction an average of a quarter-mile
wide and twenty miles long. Tornadoes may accompany thunderstorms and
hurricanes. (www.jlab.org/ehs/manual/EHSbook-182.html)

So, tornadoes are very strong rotating winds that may include rain, lightning, and hail. They are very destructive, and they are the fastest moving winds on earth. Tornadoes are created when cold win mixes with a warm current; when they meet together they start spinning. Global warming will caused an increase of tornadoes, just like hurricanes, when the earth start warming and the effects of climate change.

Floods
Floods are normal where rain's water gets jam in a place, where it doesn’t drains. It is always caused by rain; the flooding of rivers, when too much water goes into a river and it raise its level, flooding all its surroundings.
Global Warming will melt all the ice in the artic and the water level of the ocean will rise, flooding all coasts. This is something we need to solve very fast, there would not be much left of coastal cities, like Cartagena.

All of these disasters will be created by Global Warming; you can say much of Earth will be destructed if we don’t act fast. All coastal cities will be flooded by water and Tsunamis caused by the climate changes and heat. Tornadoes will destruct the center of the United States, and the hurricanes, will destroy its coasts. Many people will be affected so tray to safe the planet, because it’s just ours and right now, we are destroying it leaving us with nothing.

Hi Arrnold!

I think that tornadoes and hurricanes are very serious and that if we don't stop global warming, there will be more damage caused by natural disasters. Good job!
