First Stage of Global Cooling During 2008/09

Fri, 29 Aug 2008 02:47:16 GMT

clipped by: amgumen
clipper's remarks: Mr. Dilley of Global Weather Oscillations has found seven different types of recurring gravitational cycles ranging from the very warm 460,000 year cycle down to a 230 year recurring global warming cycle. All of the gravitational cycles coincide nearly 100 percent with 2200 global warming events during the past half million years. This includes the earth’s current warming cycle which began around the year 1900, and the first stage of global cooling that will begin during 2008 and 2009.

climate researcher David Dilley utilizes nearly a half million years of data linking long term gravitational cycles of the moon explain the recent global warming, rises in carbon dioxide levels, and for 2200 global warming cycles during the past half million years.

The gravitational cycles are called the Primary Forcing Mechanism for Climate (PFM), and act like a magnet by pulling the atmosphere’s high pressure systems northward or southward by as much as 3 or 4 degrees of latitude from their normal seasonal positions, and thus causing long-term shifts in the location of atmospheric high pressure systems.

a near 100 percent correlation between the PFM gravitational cycles to the beginning and ending of global warming cycles. Global warming cycles began right on time with each PFM cycle during the past half million years, as did the current warming which began 100 years ago, and it will end right on time as the current gravitational cycle begins its cyclical decline.

Data from the UK Met Office shows that temperatures in the first half of the year have been more than 0.1 Celsius cooler than any year since 2000.

The principal reason is La Nina, part of the natural cycle that also includes El Nino, which cools the globe.

Earlier this year, one group of researchers suggested that another natural cycle, the Atlantic Multidecadal Oscillation, was likely to hold temperatures steady for about the next decade

Arctic ice refuses to melt as ordered

Just a few weeks ago, predictions of Arctic ice collapse were buzzing all over the internet. Some scientists were predicting that the "North Pole may be ice-free for first time this summer". Others predicted that the entire "polar ice cap would disappear this summer".

The Arctic melt season is nearly done for this year. The sun is now very low above the horizon and will set for the winter at the North Pole in five weeks. And none of these dire predictions have come to pass. Yet there is, however, something odd going on with the ice data.

A comparison of these maps (derived from NSIDC data) below shows that Arctic ice extent was 30 per cent greater on August 11, 2008 than it was on the August 12, 2007. (2008 is a leap year, so the dates are offset by one.

ice has grown in nearly every direction since last summer - with a large increase in the area north of Siberia

Northwest Passage (west of Greenland) has seen a significant increase in ice

Polar layered deposits on Mars: to unravel Mars’ climate history

Mars, like Earth, appears to have experienced global climate changes over the past few million years. The effects of Earth’s ice ages are well recorded in polar ice in Greenland and Antarctica. Similarly, layered deposits in both polar regions on Mars (see above) appear to record ancient Martian climate variations. Changes in the tilt (relative to the Sun) of the rotation axes of both Earth and Mars are thought to have influenced their climates

Most Mars researchers believe that the polar layered deposits are the result of variations in the amounts of dust and water ice deposited over many climate cycles, but the amount of time needed to form individual layers remains a major uncertainty

Clip Source: hirise.lpl.arizona.edu

The north polar layered deposits of Mars form a layered stack of dusty ice up to 3 kilometers (2 miles) thick. The differences from layer to layer are thought to reflect differences in the climate of Mars that existed when the layers were formed.

Scientists break record by finding northernmost hydrothermal vent field

Well inside the Arctic Circle, scientists have found black smoker vents farther north than anyone has ever seen before. The cluster of five vents – one towering nearly four stories in height – are venting water as hot as 570 F.

The vents are located at 73 degrees north on the Mid-Atlantic Ridge between Greenland and Norway. That's more than 120 miles from the previous northernmost vents found during a 2005 expedition, also led by Pedersen. Other scientists have detected plumes of water from hydrothermal vents even farther north but have been unable to find the vent fields on the seafloor to image and sample them.

We hadn't expected a lot of active venting on ultra-slow spreading ridges

That deposit is about 825 feet in diameter at its base and about 300 feet across on the top and might turn out to be the largest such deposit seen on the seafloor

The cluster of five hydrothermal vents, also called black smokers, were discovered farther north than any others previously identified. The vents, one of which towers four stories high, are located on the Mid-Atlantic Ridge between Greenland and Norway, more than 120 miles farther north than other known vents.

The active chimneys in the new field are mostly black and covered with white mats of bacteria feasting on the minerals emitted by the vents. Older chimneys are mottled red as a result of iron oxidization. All are the result of seawater seeping into the seafloor, coming near fiery magma and picking up heat and minerals until the water vents back into the ocean.

The whole deposit is about 825 feet in diameter at its base and about 300 feet across on the top and might turn out to be the largest such deposit seen on the seafloor, Lilley said.

Given the massive sulfide deposit, the vent field must surely have been active for many thousands of years

Geologic Evidence of the Cause of Global Warming and Cooling

Fri, 25 Jul 2008 01:10:27 GMT

clipped by: amgumen
clipper's remarks: The warming over the past 50 years is hardly even noticeable on the 15,000 year graph above. Compare the peaks about every 800-1000 years for the past 10,000 years (since the last full ice age), all are much warmer than what we're experiencing now. In fact the last 1,000 years has been unusually cool for this interglacial period, just looking at the graph it certainly looks like we've been over due for warming (or if our interglacial period is over another full ice age which would be much worse).

"In a Newsweek article (August 13, 2007), author Sharon Begley states “Current warming is 10 times greater than ever before seen in the geologic record. The chance that warming is natural is less than 10 percent.” Every competent geologist knows that this statement is totally false and contrary to vast amounts of well-established data. Global climates have warmed about 4-7° F in a series of ~30 year cycles since the Little Ice Age 400 years ago, all with no correlation with atmospheric CO2, yet the author claims that “the pattern of warming has a human fingerprint.” What is needed to bring clarity to the issue is not rhetoric like this, but a hard look at the huge amount of geologic data that shows we’ve had climate changes 20 times greater than the past century in a fourth of the time."

Arctica: they began keeping records in 1972

since 1980:

Ice Concentration is down a whopping 5% (down from 8.9 to 8.5 million square km)
Ice Extent is down 8% (down from 12.3 to 11.4 million sq km).

Yet the Arctic is getting most of the news. You see statements such as "On August 21, 2007, the Northwest Passage became open to ships without the need of an icebreaker. According to Nalan Koc of the Norwegian Polar Institute this is the first time it has been clear since they began keeping records in 1972." (Wikipedia) However Roald Amundsen first navigated the passage in 1906 without the use of an icebreaker (at the end of this trip, he walked into the city of Eagle, Alaska, and sent a telegram announcing his success) so the Arctic ice has certainly retreated this far in the near past. When you hear the term "record" coming from the media or the environmentalists that could mean over the past 10-30 years. When you're talking about climate you need to look at time periods over at least 10,000 years for them to have any meaning.

Antarctic Sea Ice Continues To Set Records

18% more Antarctic Sea Ice Concentration (from 9.6 to 11.2 million square km)

10% greater Antarctic Sea Ice Extent (from 13.2 to 14.5 million square km)

Where is the one area of the Antarctic that has less ice today than in 1980? The south side of the Antarctica Western Peninsula, which is all you hear about in the popular news media. If at any time in the last 2 year you've seen fear mongering over ice melting at Antarctica this is what they were talking about.

The sky is falling crowd will tell you that their computer models predicted more inland ice due to increased snow fall (of course their models predict damn near everything to happen, from cooling / warming, drought / floods, etc. / etc). But increases in sea ice is something they hadn't predicted which is why you hear almost nothing about it. They simply point to the Antarctica Western Peninsula and this or that ice shelf that is "breaking apart" (this is called calving and is something that has always happened)

Clique of IPCC climate modelers

more than two-thirds of all authors of chapter 9 of the IPCC’s 2007 climate-science assessment are part of a clique whose members have co-authored papers with each other and, we can surmise, very possibly at times acted as peer-reviewers for each other’s work. Of the 44 contributing authors, more than half have co-authored papers with the lead authors or coordinating lead authors of chapter 9

This is scientific cronyism at an alarming level. Instead of having a diversity of views from a wide range of scientists, the chapter is written almost exclusively by climate modelers speaking with one voice. The world is being driven by a group with strong vested interests and despite the highly questionable capabilities of their models

That paper provides plausible reasons why the IPCC’s estimates of climate change may be excessive and unsafe.

currently-fashionable efforts by governments to reduce anthropogenic CO2 emissions are pointless, may be ill-conceived, and could even be harmful.

Sea ice now isn't melting, but spreading. The seas have not just stopped rising, but started to fall.

Nor is the weather getting wilder. Cyclones, as well as tornadoes and hurricanes, aren't increasing and the rain in Australia hasn't stopped falling.

What's more, the slight warming we saw over the century until 1998 still makes the world no hotter today than it was 1000 years ago.

Now Prime Minister Kevin Rudd can at last stop sweating about the warming terrors he told us were coming - the horrific droughts, the dengue fever, the malaria, the devastation to our land and economy.

As for his promise this week to make your power bills go up $200 a year to stop global warming? His promise to make even food more expensive? To put gassy companies out of business, and their workers out of a job?

Biofuels threaten food supplies, rainforest and climate - yet our leaders push them in the name of the environment

Farewell the age of reason, welcome the idiocracy. Only George Orwell could have invented - and named - the government's Renewable Transport Fuel Obligation (RTFO) that came into operation yesterday. It is the latest in a long line of measures intended to ease the conscience of the rich while keeping the poor miserable, in this case spectacularly so.

The consequences of the RTFO have been much trumpeted on these pages. It says enough that one car tank of bio petrol needs as much grain as it takes to feed an African for a year, or that a reported one-third of American grain production is now subsidised for conversion into biofuel. Jeremy Paxman pleaded the cause of this latest green wheeze on Monday's Newsnight, while the United Nations food expert, Jean Ziegler, screamed for it to stop: "Children are dying ... It is a crime."

Perito Moreno Glacier in Argentina

clipper's remarks: There is a news report quoting one of the most important experts in the glacier that has
the following headline: "The Perito Moreno rupture is not consequence of greenhouse
effect: "Ricardo Villalba, director of the Argentinean Institute of Glaciology, Snow and
Enviromental Sciences (Ianigla) tells Los Andes newspaper that the position of the ice
and the tides can be blamed for this unusual breakup in the winter."

Regarding the Perito Moreno glacier in Argentina, which the BBC claimed had a huge
ice dam on Argentina's Perito Moreno glacier is about to break apart for the first time
during the southern hemisphere winter, there is an interesting quote in the Argentinean
press today:

Victor Jorge Leis, operational director of the National Weather Service of Argentina,
expressed doubt about global warming as the cause of the rupture of the glacier. "It is too
difficult to establish a connection with the greenhouse effect because temperature has not
been much above normal in the region in the last few months. Besides, temperature is just
one factor in the ice behavior and wind and oceans tide should not be ignored", he told.
Other experts mentioned that the glacier tip is 400 years old, what justifies its fragility".

The last time it ruptured in July was in 1951 (coming off a strong La Nina).
