Hurricanes and typhoons at their peak intensities are shifting away from the equator and towards the poles, scientists reported Wednesday, potentially placing coastal areas that are unaccustomed to deadly storms in their path if the trend continues. Satellite data going back to 1980 show a global average shift of about 35 miles each decade on both sides of the equator, the experts announced in the peer-reviewed journal Nature.
For Kossin, the key takeaway is that scientists should double down on figuring out what’s driving the expansion of the tropics because that seems to hold the key to stopping, or at least slowing, the shift of big ocean storms to new areas.
The tropics’ expansion has been linked to manmade problems: ozone depletion, air pollution and greenhouse gases tied to global warming, Kossin noted. But figuring out to what extent each plays a role is needed before finding a fix.

Do people really expect the weather to stay the same forever?
Serious question there.
I'm starting to wish I had a nickel for every climate study and story. I wouldn't have to work.

Of course not. If you read the article, it says that Scientists are trying to figure out the extent of mankind's role in this whole mess. We can't do anything about what mother Nature does but we can do something about ourselves.
WeatherAction is involved in the Global Warming /Climate Change debate where we point out that the world is now cooling not warming and there is no observational evidence in the thousands and millions of years of data that changes in CO2 have any effect on weather or climate. There are no scientists in the world who can produce such observational data. There is only effect the other way, namely that ocean temperatures control average CO2 levels.

As a common person, which we all are, unles you are a billionaire. We have no say so in what we can change.
Corporations are limiting access to the availability energy and transportation.
330,000,000 Americans cannot just give up the automobile. Granted not everyone drives one, but every single Amercan depends on trucking in some way or another. Even if you live off the grid, you still need supplies sometimes.
People have to provide for their families. Our economy is set up on oil. To change this means a complete restructuring of our way of life, economy and living.
I hate to have a pessimistic view of it ll, but capitolism says money makes the rules.
and the one's with no money are forced to follow those rules.

What corporations are limiting your transportation or energy?
If I don't have a car I have buses, taxis, trains etc. As long as I pay my electric bill I have power.
Some people just thrive in the roll of victim. Oh poor me everything is out of my control.

The Hadley cell mechanism is well understood. The atmospheric circulation pattern that George Hadley described to provide an explanation for the trade winds matches observations very well. It is a closed circulation loop, which begins at the equator with warm, moist air lifted aloft in equatorial low pressure areas to the tropopause and carried poleward. At about 30°N/S latitude, it descends in a cooler high pressure area. Some of the descending air travels equatorially along the surface, closing the loop of the Hadley cell and creating the Trade Winds.
Though the Hadley cell is described as lying on the equator, it should be noted that it is more accurate to describe it as following the sun’s zenith point, or what is termed the "thermal equator," which undergoes a semiannual north-south migration. ...

I read about this today on accuweather. I almost posted about it.
I'm in a hurricane zone in the Gulf of Mexico. This means that hurricanes can develop and strengthen much closer to my area than they have in the past and it's going to be a progressive trend.
Does this mean that each Hurricane season from now on will slowly get worse? I guess time will tell but the US and UK are right in the path.

We are now in a period of major volcanic activity with huge amounts of volcanic ash suspended in the atmosphere which in turn affects the wind patterns/jet streams and then the oceanic currents which then increase the changes in the trade winds & wind patterns in a step-by-step pattern of Change from the norm of our weather /climate
