Global warming myths and facts

Models?
Models are unreliable and are proven wrong often.

Look at history.

The deadliest storm happened in the 18th century, not the 19th, 20th or even the 21st century. Better luck next time, denier of facts.

You are a right-wing idiot.

They love to cherry pick one outlier and say, "See you're wrong!"

Do you have any idea how many hurricanes have come along since 1780?

They ARE getting more intense, as the NOAA scientist said.

Not as many people are killed now because, well, it IS the 21st century. Smallpox doesn't kill as many people either.

I know there have been less since then. A colder climate has more hurricanes and that is a fact. Warm weather always causes evaporation. If that was all that it took for hurricanes to form they would be in every ocean in the tropical regions and it would be uninhabitable. The simplistic assertion that evaporation alone can fuel a hurricane is nonsense that is contrary to science. Ask any hurricane expert if warmth alone is what fuels hurricanes. Have you noticed that hurricanes on the US west coast are rare? The Atlantic ocean is where most hurricanes form. Hawaii doesn't have a hurricane problem like they do in Puerto Rico. You don't have the slightest clue as to why that is, do you?

You are a left wing follower who is ignorant of science. Furthermore, you are perverting science to fit your political bias. The population is higher now. There should be more deaths from hurricanes, not less.

We have the ability to control our environment.

Climate change is both natural and preventable with human ingenuity.

Yup. If New York gets snowstorm in October, throw out the science.

You are a dummy.

"These storms are called hurricanes in the Atlantic and are called typhoons and tropical cyclones in other parts of the world. For one to form, there needs to be warm ocean water and moist, humid air in the region. When humid air is flowing upward at a zone of low pressure over warm ocean water, the water is released from the air as creating the clouds of the storm."

"As it rises, the air in a hurricane rotates. Air drawn into the center of a hurricane curves to the right in the Northern Hemisphere and toward the left in the Southern Hemisphere due to the Coriolis effect - a result of the Earth's rotation. Near the equator, where there is no Coriolis effect, hurricanes cannot form within 300 miles (500 kilometers) of the equator.

Storms grow if there is a continuous supply of energy from warm ocean water and warm, moist air. Tropical storms can grow into hurricanes, and hurricanes can grow into stronger hurricanes. However, only a small number of storms grow into tropical storms. Even fewer become hurricanes.

Storms weaken when they moves over areas with cooler ocean water. There isn’t nearly as much energy in the water to fuel the storm. Nor is there as much humidity in the air. Hurricanes also weaken when they travel over land."

From the same page
What does a storm need to form and grow?

Hurricanes take energy from the warm ocean water to become stronger. While a hurricane is over warm water it will continue to grow.
Because of low pressure at its center, winds flow towards the center of the storm and air is forced upward. High in the atmosphere, winds flow away from the storm, which allows more air from below to rise.
The air that rises needs to be warm and moist so that it forms the clouds of the storm. Warm, moist air is found above warm, tropical ocean waters.
A hurricane also needs the winds outside the storm to be light. These winds steer the storm, but are not strong enough to disrupt it.

But hey I'm sure you can find facts to prove your alternate scientific view.

It is true that you need evaporation for a hurricane to form a strong storm, but you also need condensation. Any article that omits condensation is a poor article. You need both to fuel the cycle, not just one. That is why more hurricanes form in a colder climate than a warmer climate.

Your inability to think things through is breathtaking. Yes you need condensation but not due to cold weather you nonce...

"Silently and invisibly, water changes from liquid to vapor and enters the atmosphere. The energy required to make this change comes from the sun, and this energy is lying in wait — latent — ready to be released when the vapor is condensed into liquid again. This happens in rising air in a cloud or thunderstorm.

However, this process alone is not enough to power a hurricane. A hurricane adds fuel to its own fire by drawing surface air toward its low-pressure center. The tight pressure gradient nearer the center means that the winds grow stronger as the air approaches the eye. The faster the wind blows, the more evaporation takes place (this is why you blow-dry wet hair or hands instead of merely warming them).

Increased evaporation means more water vapor in the air and more energy ready to be liberated in the hurricane’s thunderstorms as water vapor condenses. In short, evaporation and condensation of water are the keys to understanding the power of tropical cyclones.

How strong is the engine that powers a tropical cyclone? The energy released by condensation in a single day in an average hurricane is at least 200 times the entire world’s electrical energy production capacity. Part of this energy is expended reducing the central pressure of the storm and strengthening the winds."

" In short, evaporation and condensation of water are the keys to understanding the power of tropical cyclones."

Exactly what I told you, it takes both. Your inability to think things through is breathtaking. How are you going to get condensation without a colder upper atmosphere? DUH!

Here is an excerpt from the link below:

"The temperature gradient is proportional to the so-called available potential energy (APE). As you might guess, like any object in the planet’s gravitational field, the atmosphere has potential energy. A part of potential energy can be converted to the energy of atmospheric motion; hence, it is called available. The essential part of the conversion is vertical movement of air – this is how the air masses approach equilibrium, consuming APE. APE is actually a tiny bit of the total amount of energy (about 0.5😵, but in the absence of other energy sources it is the only reservoir that can feed the atmospheric circulation.

Strong temperature gradients are common in the polar atmosphere, for example, during massive outbreaks of cold air over warm ocean surface. As a result, sharp baroclinic zones develop, and a vortex can grow bigger and bigger, drawing energy from the APE of the mean flow.

It is believed that APE is one of the primary energy sources for polar lows. It prevails over other sources, especially when a polar low appears as a comma-shaped cloud on the satellite images"

As you can see I was right all along and you were in denial like you always are.

Interesting perspective. However.

https://www.scientificamerican.com/article/why-do-hurricanes-hit-the-east-coast-of-the-u-s-but-never-the-west-coast/
Comparing Hurricanes off the East Coast with Hurricanes off the West Coast this is what is known. You can read the whole article, but these are a few germane excerpts.

" Along the East Coast, the Gulf Stream provides a source of warm (above 80 degrees Fahrenheit, or 26.5 degrees Celsius) waters, which helps to maintain the hurricane. Along the West Coast, however, ocean-surface temperatures rarely rise above the lower 70s F. (the low 20s C.), even in the middle of summer. Such relatively cool temperatures do not provide enough thermal energy to sustain a hurricane's strength. "

"Hurricanes almost always form over ocean water warmer than about 80 degrees F. in a belt of generally east-to-west flow called the trade winds. "

And this.

""Essentially, the very cold water that upwells off the California coast and gives coastal California such a cool, benign climate also protects it from hurricanes. Real-time maps showing the distribution of the potential intensity of hurricanes clearly show the various regions worldwide that can sustain hurricanes."

And you've heard of the term lapse rate, yes? That says that the temp drops 5deg F with every 1000 ft. so you don't need mid winter to get a colder upper atmosphere for condensation.

Here's the truth, you are either, willfully ignorant, dumb, or a misinformation troll. Maybe all three. If you thought science was your bag, think again!

And before you comment, how tall do Hurricanes form into the atmosphere?

https://yourmileagemayvary.net/2020/09/20/can-you-fly-over-a-hurricane/

Up to 20,000 to 30,000 ft which is why commercial flights do not generally fly over them. Any idea what the temp is up at around 20,000 ft? Well if its 80deg F at sea level, its 8.6deg F at 20,000ft. Well below freezing, and well able to produce that temperature gradient favorable for condensation even though its warm at sea level.

So once again, either you are:- willfully ignorant, dumb, or a misinformation troll, or maybe all three. If you thought science was your bag, maybe not!

None of that contradicted what I wrote. My science is just fine.
Why do you always make false claims of victory. I was right all along. It requires both evaporation and condensation. Condensation requires a colder upper atmosphere. A colder upper atmosphere of greatest temperature contrast happens in a colder climate. Warmth alone is not enough. Not enough temp contrast to feed the cycle for a strong storm. Condensation must happen to bring the upper air down. Evaporation alone is no good because the air would rise and just stay up there. No cycle.

No cycle, no big storm.
