A major storm caused spaces in the center and south of the United States on Wednesday that launch severe floods and hurricanes From Arkansas to Michigan. Conditions are expected to worsen on Friday, when the soil becomes saturated and the water rise: National Weather Service Warning From “a flashing, life, catastrophic, and possibly flabby flood”, along with the risk of very large cold and more contestants. Eight people It has been confirmed so far 33 million Under flood hours in 11 states.
Although scientists will need appropriate research to clarify the amount of climate change that contributes to these storms, what is known as the study of chain of transmission can generally say how planetary warming may exacerbate such an event. Climate change does not necessarily create this storm – it could have occurred independently of all the additional carbon that humanity pumped into the air – but there are some clear trends that make rain worse.
“In a world without burning fossil fuels, this event will happen once in a lifetime-and this is a kind of what the national weather service says,” said Mark Alesi, a climate classmate at the Union of Scientists concerned in Massachusetts. “But with burning fossil fuels, with more heat -trap emissions, with warming planet, this event will become more frequent.”
The rain changes because the Earth sweats. When the sun evaporates from the water from the surface of the earth, this moisture rises to the atmosphere, condenses, and falls as purity. but Greenhouse gases The heat trap there, so the planet sweats more responsive. In other words, it attracts energy balance.
The warmer atmosphere also gets “thirst”: for each degree one degree of warming, air can carry water more than 6 to 7 percent. This means that more moisture is available to fall like rain: At the end of this week, the slow storm is expected to get rid of 15 inches Rain in some areas. Alesse said: “The sponge, which is the atmosphere in this case, will become greater, which allows the sponge to carry more water and carry it from the inner oceans.” “This can be linked to this event here.”
The body of the water concerned here is the Gulf of Mexico. The outbreak of hurricanes and heavy rains is a typical matter for this time of the year, as warm water sends moisture to the south and central United States. Currently, the Gulf of Mexico is exceptionally warm. “There is a lot of fuel for these rain storms to lead to more floods,” Alessy said. (The effect of climate change on hurricanes in the United States, though, Not))
So the most warmer Gulf of Mexico does not only produce more moisture, but the atmosphere is also able to absorb this moisture more than it can before the climate changing the human being. In fact, the United States government Special climate assessments Warning that rain has already become more extreme throughout the country, as well as economic damage to the resulting floods. It is expected to get worse with all a little additional warming.
The problem is that American cities were not designed to bear this new atmosphere. The urban schemes are designed for a different climate yesterday, with gutters and sewers that whisk rain water as quickly as possible to prevent floods. With the most extreme rainfall, this infrastructure cannot continue, so water and floods accumulate. And with storms that last for several days, such as those who are tearing in Arkansas and Kentucky at the present time, the soil becomes saturated so that you cannot tolerate more water, which exacerbates the floods more. On Thursday, the rescue sets were in Nashville, Tennessee was Jogging Consulting the high levels of water.
Now scientists will have to choose data to know, for example, how many additional rain that has decreased the storm due to the impact of the sponge and the bound of the Gulf of Mexico. But the general trend is very clear: with the planet’s high temperature, it does not always become dry, but also wet.
