So here's forecast from Oct. 2014 that sees the population going from 316 million to just 69 million by 2025 and it seems to confirm the WOW.
There is another striking projection which should alarm every American. In 2013, the U.S. military budget was $726 billion dollars. However, the projected 2025 projected budget is only $8 billion dollars. This clearly points to the fact that the CIA, through Deagel, is projecting that the United States is going to be militarily conquered within the next 10 years. The mere $8 billion dollar projected 2025 military budget speaks to a domestic martial law type of occupation force. With this kind of budget, the U.S. would not even be able to engage in regional conflicts.The Deagel documents clearly speak to who the winners and losers of the coming global conflict will be. In the Deagel document, Russia, China, Syria, Saudi Arabia, Iran and India maintain their respective populations or increase their populations by the year 2025. The United States and Britain undergo severe population reductions. AGAIN, PLEASE NOTE THAT THESE LINKS HAVE BEEN SCRUBBED BUT THE DEAGEL WEBSITE REMAINS INTACT. TOO MANY VISITORS, TOO MANY QUESTIONS
SCIENCE NEWS The ghosts of ancient hurricanes live in Caribbean blue holesCore samples pulled from submarine sinkholes reveal a 1,500-year record of powerful hurricanes that passed through the Bahamas on the way to the U.S. East Coast.

South Andros Island, part of the Bahamian archipelago, is a sandy slice of paradise whose shores conceal buried geological treasures: blue holes. Hiding in the depths of these ethereal submarine sinkholes lay ancient sediment sandwiches whose layers betray the bygone passages of powerful hurricanes.
The isle is often a pitstop for hurricanes heading toward the Gulf of Mexico or North America’s east coast. If these lithic libraries could be accessed, scientists could travel back in time and compare the Atlantic hurricanes of today with the specters of storms past.
With some ad-hoc engineering ingenuity, researchers have extracted several of these towers of sediment from their blue hole homes. As reported earlier this month in the journal Paleoceanography and Paleoclimatology, one 59-foot-long continuous core chronicles the encounters the island has had with tropical cyclones going back a jaw-dropping 1,500 years.
It has peaks and troughs in activity, but in general the sediments show that South Andros Island has been a hurricane highway for much of the last millennium and a half. And although the island has been visited by dozens of tropical cyclones during the past 150 years, just two powerful hurricanes have paid it a visit during that timeframe.
That likely won’t last, explains the study’s lead author Lizzie Wallace, a doctoral student in the Massachusetts Institute of Technology and Woods Hole Oceanographic Institution Joint Program in Oceanography. The island’s unearthed history indicates that calmer recent times are probably atypical, meaning the island has just got lucky lately.
As human-caused climate change continues to warm the world, hurricanes will get wetter, more intense and more capable of flooding coastlines. Along with the revelations buried in the ancient cores, it appears likely that the island, and the wider region, may be at a greater risk of intense hurricane strikes in the future than modern instrumentation records alone can show.
Raiders of the lost bark. Climate scientists, perpetually ravenous for more data, are increasingly turning to a myriad of unusual sources. These including the weather logs taken by 19th century sailors, the changing flavors of French wine grapes, and even within the poop of Romanian bats.
The same creative thinking is starting to apply to long-gone hurricanes. The National Oceanic and Atmospheric Administration (NOAA) only has Atlantic hurricane records as far back as 1851, so researchers are hoping to find traces of older ones in antiquated sediments.
Hurricane-strength winds tear up the environment. Jeffrey Donnelly, Wallace’s supervisor, noticed that muddy sediments within marshes, lakes, and ponds in Massachusetts seemed to record the pandemonium. So do blue holes, sinkholes carved into erodible rock and flooded with water that can capture larger sand grains and shell fragments blasted in their direction.
Several of these natural hurricane archives in a few Atlantic locales, from western Florida to multiple Caribbean Sea shorelines, have already been liberated by researchers. But South Andros Island, positioned along a well-known contemporary hurricane path and pockmarked with untapped blue holes, was especially enticing for Wallace and her team.
Those watery pits are deep, near sandy beaches and reefs, and are shielded from the wider sea, allowing them to take on centuries’ worth of sediment with minimal disruption and interruptions. They are also low in oxygen, discouraging life from burrowing in and inconveniently reordering the layers.
Visiting the island in late 2014, the team attempted to dig out continuous cores from several blue holes. That was easier said than done: these otherwise deep sinkholes were in shallow water, meaning most core drill-capable boats cannot access them. Instead, Wallace’s team had to build their own drill rigs made from aluminum tubes, wooden planks, and inflatable dinghies, which were then towed above their targets.

It didn’t always work, but they ultimately succeeded in extracting cores from three blue holes, including the 312-foot-deep portal responsible for that 59-foot-long core. Within tell-tale hurricane layers were fragments of mangrove trees, which were radiocarbon dated to provide dates for each hurricane.
The century of silence The cores show that there have been plenty more hurricanes impacting the island in the past 1,500 years than the modern observational record suggested. Other studies, looking at different locations, have drawn similar conclusions.
Tom Knutson, the Weather and Climate Dynamics Division leader at NOAA, who wasn’t involved with the study, says he is constantly surprised by this. This curiosity alone, he adds, demonstrates the value of blue hole expeditions.
There are also multiple peaks and troughs in the hurricane frequency, something seen in cores taken elsewhere in the Atlantic. Comparisons to other cores show that the low-pressure belt encompassing the equator–the Intertropical Convergence Zone, or ITCZ – plays a major role.
The zone moves to whichever hemisphere, north or south, is warmest at the time. Thanks to a long-term cooling trend in the Northern Hemisphere, the zone has slowly been moving south for the last 8,000 years. But superimposed on that drift are abrupt, shorter-term changes, up and down, which have a variety of possible causes.
When the zone shifts south, it leads to lower sea-surface temperatures and disrupting winds in the Atlantic Ocean’s hurricane-making factory, which stifles their production. Indeed, the team’s new data indicate that during periods of hurricane inactivity at South Andros Island the belt is in a more southerly position.
The 13th century, though, stood out for its steadfast silence. From 1204 to 1273, there were no major hurricanes at all. After 1273, as many as eight major cyclones then came along and pummeled it, says Wallace.
The team speculates that the near-century of hushed hurricanes is perhaps attributable to an as-of-yet unidentified burst of explosive volcanic activity. That can create airborne clumps of sulfuric acid, which can partially block out the sun for a handful of years and briefly make it far more difficult for the sea to heat up and fuel tropical cyclones.
Enough sulfate aerosols can also cause the ITCZ to migrate, says Matthew Watson, a volcanologist at the University of Bristol who wasn’t involved with the study. If, say, a major volcanic paroxysm happened in the Northern Hemisphere, it could force the ITCZ south into problematic terrain for hurricane formation.
Promisingly, 13th century ice cores from Greenland and Antarctica do show an increased load of these aerosols. But a different period of plentiful aerosols matches up with a time of high hurricane activity at the island. Unless the volcano responsible can be pinpointed–a notoriously difficult task–it’s too early to say what caused the silence in the 1200s.
Never-ending ghost hunt. This is a “fantastic dataset,” and a blue hole core with 1,500 years’ worth of data is “pretty unprecedented,” says Alexander Farnsworth, a paleo climatologist at the University of Bristol who wasn’t involved in the study. It does, however, leave the story of Atlantic hurricanes still largely incomplete.
The core doesn’t capture every hurricane. Modern observations of local hurricanes, and the deposits they did or were expected to leave behind, revealed that only Category 3 hurricanes—those with windspeeds of no less than 111 miles per hour—created identifiable layers. Any weaker hurricanes, even those that directly hit the island, aren’t documented.
That record also only provides a hurricane count and a minimum wind strength; it cannot reveal any more detailed characteristics of the cyclones. Plus, it’s just one core of a small total number. Plenty more cores, up and down the Atlantic, will be needed to see which data points and patterns are repeatable or not, says Farnsworth—a point Wallace agrees with.
What is important right now, says Watson, is that this extraordinary dataset can be opened up to the wider scientific community. Some may be able to hunt down that 13th century volcanic culprit, while others could identify what else may be moving the zone.
All in due course. Hunting down the submerged ghosts of hurricanes takes time, and scientists are only just getting started.

Dust and smoke would definitely help counteract a few things. Solar x-ray flux is picking up.
And it looks like a train is coming later next week.
And ENSO dynamics are currently swinging La Nina-ward which favors Atlantic hurricanes. bom.gov.au
"La Niña ALERT. This means that even though the El Niño–Southern Oscillation is currently neutral, the chance of La Niña forming in the coming months has increased to around 70%. This is roughly three times the normal likelihood of an event forming in any year. This status change follows a renewal of cooling in the tropical Pacific Ocean towards La Niña thresholds over recent weeks, as well as the persistence of the Southern Oscillation Index (SOI) at La Niña levels and strengthened trade winds at La Niña levels. Climate models indicate further cooling is likely, with four of seven models suggesting La Niña could return by early-to-mid southern hemisphere spring."
