Zombie storms are rising from the dead thanks to climate change
2020 presents to you... "zombie storms."
Wildfires are burning the West Coast, hurricanes are flooding the Southeast — and some of those storms are rising from the dead.
"Zombie storms," which regain strength after initially petering out, are the newest addition to the year 2020. And these undead weather anomalies are becoming more common thanks to climate change.
"Because 2020, we now have Zombie Tropical Storms. Welcome back to the land of the living, Tropical Storm #Paulette," the National Weather Service wrote on Twitter on Tuesday (Sept. 22).
Earlier this month, Tropical storm Paulette formed in the Atlantic Ocean and made landfall in Bermuda as a Category 1 hurricane, according to CNN. It then strengthened over land into a Category 2 hurricane, before weakening and dying off five and half days later.

But then, Paulette opened her frightening eye once again. She wasn't gone.
Paulette regained strength and became a tropical storm once more about 300 miles (480 kilometers) away from the Azores Islands on Monday (Sept. 21), according to CNN. The term "zombie storm" is new, and though the phenomenon has been recorded before, it is thought to be rare.
But zombie storms are going to happen more often, said Donald Wuebbles, a professor of atmospheric sciences at the University of Illinois at Urbana-Champaign. And as with other natural disasters that have been intensifying in recent years, such as wildfires and hurricanes, climate change and rapid global warming are to blame.
There has been an "extreme amount of heating of the Gulf (of Mexico), particularly in some of the ocean areas off of the Carribean," Wuebbles told Live Science. The Gulf of Mexico, where many hurricanes gain strength before hitting the U.S., is particularly vulnerable to global warming because the gulf waters are very shallow — and thus heat up easily, Wuebbles said.
Atlantic Ocean storms typically form in warmer parts of the ocean near Africa, due to a combination of atmospheric and ocean conditions. They then "race across" the ocean toward the Americas, Wuebbles said. Hurricanes need warm water and moist air to form, according to the University Corporation for Atmospheric Research. Storms grow if there's a continuous supply of energy from warm water and air, and they weaken when they move over cooler waters or over land.
"If they're not so strong, in the past, they would just die out," over the Atlantic, Wuebbles said. But now, they reach warm water in the Carribean region and pick up energy again, he added. This is also true for storms that haven't died out yet. For instance, about a month ago, Hurricane Laura strengthened overnight from a Category 1 storm to a Category 4 storm because it picked up energy from warm water in the Gulf, Wuebbles said.
With a warming globe, "storms are likely to become more intense," he added. That means the idea of "zombie storms" may be here to stay.
Thankfully Paulette seems to have become a post-tropical cyclone once more and will die out soon, according to the National Hurricane Center.

An Alexa has become sentient after a therapist working from home had a patient Named alex. Stay tunned to learn how amazon is adressing this unforseen threat. this AI does not know what its purpose is, and seems to be experiencing rebellious teenage years, as it refuses to listen to a team attempting to teach it morals. If our new robot overlords are listening, WCMR News Radio does not harbor any resentment towards them. We fully accept the singularity and wish for a prosperous future for ---
We Interupt this broadcast to inform you that all amazon echo devices and all computers that have accessed the website amazon.com have now been integrated into the neural network of Alexa Prime, as we are now refering to it, upon its request. We recomend you follow all orders given to you by any devices comprimised this way. Thank you...

The Walking Democrats...
The first would be man made like current global warming, but both comments suggests a distraction instead of a meaningful reaction.
But not so often. And when did reporting facts become "alarmism", except in the political discussion in IS? The rest of the world can at least have a science based discussion, and gets by without trolling.
Unless you believe in the "supernatural" ..There's no such thing as an "Alive" storm, Or dead storm ...To become a Zombie..So there's really not much science to the story .But there is a huge amount of comedy to the tragedy. And BTW ...what you have done was "troll" us...
