Sen. Aisha Alhassan said this during a media briefing. Alhassan said the move was borne out of the resolution by African leaders to end child marriage during the 25th African Union Ordinary Session.

I mean what if the other African countries never made such resolution?

Every year, trade winds over the Sahara Desert sweep up huge plumes of mineral dust, transporting hundreds of teragrams -- enough to fill 10 million dump trucks -- across North Africa and over the Atlantic Ocean. This dust can be blown for thousands of kilometers and settle in places as far away as Florida and the Bahamas.

The Sahara is the largest source of windblown dust to Earth's atmosphere. But researchers from MIT, Yale University, and elsewhere now report that the African plume was far less dusty between 5,000 and 11,000 years ago, containing only half the amount of dust that is transported today.

In a paper published today in Science Advances, the researchers have reconstructed the African dust plume over the last 23,000 years and observed a dramatic reduction in dust beginning around 11,000 years ago. They say this weakened plume may have allowed more sunlight to reach the ocean, increasing its temperature by 0.15 degrees Celsius -- a small but significant spike that likely helped whip up monsoons over North Africa, where climate at the time was far more temperate and hospitable than it is today.

"In the tropical ocean, fractions of a degree can cause big differences in precipitation patterns and winds," says co-author David McGee, the Kerr-McGee Career Development Assistant Professor in MIT's Department of Earth, Atmospheric and Planetary Sciences. "It does seem like dust variations may have large enough effects that it's important to know how big those impacts were in past and future climates."

McGee's co-authors include lead author Ross Williams, a former graduate student at MIT; along with Christopher Kinsley, Irit Tal, and David Ridley from MIT; Shineng Hu and Alexey Fedorov from Yale University; Richard Murray from Boston University; and Peter deMenocal from Columbia University.

A wet Sahara

Around 11,000 years ago, Earth had just emerged from the last ice age and was beginning a new, interglacial epoch known as the Holocene. Geologists and archaeologists have found evidence that during this period the Sahara was much greener, wetter, and more livable than it is today.

"There was also extensive human settlement throughout the Sahara, with lifestyles that would never be possible today," McGee says. "Researchers at archaeological sites have found fish hooks and spears in the middle of the Sahara, in places that would be completely uninhabitable today. So there was clearly much more water and precipitation over the Sahara."

This evidence of wet conditions shows that the region experienced regular monsoon rains during the early Holocene. This was primarily due to the slow wobbling of Earth's axis, which exposed the Northern Hemisphere to more sunlight during summer; this, in turn, warmed the land and ocean and drew more water vapor -- and precipitation -- over North Africa. Increased vegetation in the Sahara may have also played a role, absorbing sunlight and heating the surface, drawing more moisture over the land.

"The mysterious thing is, if you try to simulate all these changes in these early and mid-Holocene climates, the models intensify the monsoons, but nowhere near the amounts suggested by the paleodata," McGee says. "One of the things not factored into these simulations is changes in windblown dust."

Tracking a dust plume

In their results published today, McGee and colleagues propose a reduction in African dust may indeed have contributed to increasing monsoon rains in the region. The researchers came to their conclusion after estimating the amount of long-range windblown dust emitted from Africa over the last 23,000 years, from the end of the last ice age to today.

They focused on dust transported long distances, as these particles are small and light enough to be lifted and carried through the atmosphere for days before settling thousands of kilometers away from their source. This fine-grained dust scatters incoming solar radiation, cooling the ocean's surface and potentially affecting precipitation patterns, depending on how much dust is in the air.

To estimate how the African dust plume has changed over thousands of years, the team looked for places where dust should accumulate rapidly. Dust can sink to the floor of open ocean, but there layers of sediment build up very slowly, at a rate of 1 centimeter every 1,000 years.

Places like the Bahamas, by contrast, accumulate sediment much more quickly, making it easier for scientists to determine the ages of particular sediment layers. What's more, it's been shown that most of the windblown dust that has accumulated in the Bahamas originated not from local regions such as the U.S., but from the Sahara.

Dust's climate role

McGee and his colleagues obtained sediment core samples from the Bahamas that were collected in the 1980s by scientists from the Woods Hole Oceanographic Institution. They brought the samples back to the lab and analyzed their chemical composition, including isotopes of thorium -- an element that exists in windblown dust worldwide, at known concentrations.

They determined how much dust was in each sediment layer by measuring the primary isotope of thorium, and determined how fast it was accumulating by measuring the amount of a rare thorium isotope in each layer.

In this way, the team analyzed sediment layers from the last 23,000 years, and showed that around 16,000 years ago, toward the end of the last ice age, the dust plume was at its highest, lofting at least twice the amount of dust over the Atlantic, compared to today. However, between 5,000 and 11,000 years ago, this plume weakened significantly, with just half the amount of today's windblown dust.

Colleagues at Yale University then plugged their estimates into a climate model to see how such changes in the African dust plume would affect both ocean temperatures in the North Atlantic and overall climate in North Africa. The simulations showed that a drop in long-range windblown dust would raise sea surface temperatures by 0.15 degrees Celsius, drawing more water vapor over the Sahara, which would have helped to drive more intense monsoon rains in the region.

"The modeling showed that if dust had even relatively small impacts on sea surface temperatures, this could have pronounced impacts on precipitation and winds both in the north Atlantic and over North Africa," McGee says. Noting that the next key step is to reduce uncertainties in the modeling of dust's climate impacts, he adds: "We're not saying, the expansion of monsoon rains into the Sahara was caused solely by dust impacts. We're saying we need to figure out how big those dust impacts are, to understand both past and future climates."

I seriously doubt that.Learnt Buhari's mum also died while in prison and was not also allowed to be at the burial site.Talk of Karma.Payback time.

This is serious!

Fabulosdave01:
You're talking as if you don't know Nigerians. They'll use substandard materials and charge higher. Not everything must be local

What kind of silly stereotyping is this?

Lol... and the pressure keeps mounting in Nigeria.

Oshiomole? I doubt this.

Does this apply to people in the PFAs?

hahn:
You are not helping.

There people who believe in your god who are successful and others who are suffering

There people who believe in other gods who are successful and others who are suffering

There are people who believe in no god and are successful and others who are suffering.

The belief or disbelief in any god is not a guarantee for success or failure.

The op should be in the business section

I'm into ICT business... I can create and manage databases, design/develop websites, digital marketing etc... but things are not just fine atm.

hahn:
Lol. This is actually the problem.

God is not responsible for you not getting a job. You are.

There is no need shifting the blame on god.

I would advice you start a business. If you cannot get a job, create one.

We cannot control what happens to us in this world, we can only control how we react to it.

There is no devil or god. Just humans.

Take responsibility for your life. No need to play the blame game.

Then why do we pray for daily bread. Why do we pay tithes just to be blessed?

I have always been in business partially until now. What's it with the defense?

Dreal11247:
I can feel your frustration. Are you praying and fasting just to be blessed? Are you just following just for material benefits? What of the promise of eternal life? Is it just like an illusion to you? These and many other questions need to be answered. You statement is a proof that you were like following God with the mindset that if your needs were not met, then, God is not real. But you are wrong. Your refusal to serve him can never stop him from being God. Even if the whole world decides to worship the devil, He still remains. His teachings make us to understand that serving Him is for our own good. But seek ye first the kingdom of God and His righteousness, and all these things shall be added unto you. One thing I know is that God cannot fall. He will surely reward you in His own way and at Own appointed time.

I have always worshipped him and did not do so with the mindset as postulated by you.

Why would things keep failing? even when we prayed against such? Why would he make some rich while others wallow? Bleep that.

For over 20 years, I have been praying for and against things.
Yet bad things keeps happening anyways.

Like job loss a day after wedding and non till date.

Trying to be self sufficient with my skills but things are stiff.

I have done sacrificial offerings, fasting, seed sowing, praises, prayers all the time, but he is too powerless to act.

If it's the devil that is responsible for these bad stuffs, why can't destroy it or them so that I can concentrate on worshipping him.

Obviously prayers doesn't work or except to some other powers that I'm yet to discover.

But right now, God does not exist and if he does, he has no power and if he's got some power, maybe he is bias or selfish or he does not care about some people.

HAH:
Half of FAAN are igala from Kogi. Kogis quota is filled up so she ask her people to claim other states, you will see someone claiming Sokoto that cannot speak Hausa fluently.

I learn she is seeking a political position in future and truly they praise her in her igala land for helping kith and kin

You know others do theirs too.
Hausa --- NNPC, CBN and Customs.
Igbo---- Nig. Prisons, Consumer protection board, Ministry of information etc.
Yoruba--- NBS, Ministry of finance etc.

But I don't think these allegations are true though.

ICQuinn:
Justice!!!! I'm so happy

Did you say justice?

Did you know that lesbianism is a federal offence in Nigeria?

Why is chidima not arrested?

LecciGucci:
Suits them right!...Fools. She did wrong but u guys are devils. I pray u rot in jail

Why should they go to jail in the 1st place?
Lesbianism is federal crime... why was she not arrested?
Fake country.

Maybe she want to go back to the sampling method thing... who knows.

Brainwashed kids will say nothing is wrong with her act in the video...

Birds who are of the same feather and category will defend her.

Be sincere, the rich man isn't an ex.
