New research has found that from 20,000 to 7,000 years ago Great Britain was surrounded by a vast area of dry land that reached as far as Denmark.

New research has found that from 20,000 to 7,000 years ago Great Britain was surrounded by a vast area of dry land that reached as far as Denmark.

The research suggests that the populations of these drowned lands could have been tens of thousands, living in an area that stretched from Northern Scotland across to Denmark and down the English Channel as far as the Channel Islands.

As the ice age ended and sea levels rose, this land was slowly swamped and engulfed by the North Sea.

While thousands protest the restarting of any nuclear power plants in Japan following last year’s earthquake, some scientists have questions about one particular plant.

While thousands protest the restarting of any nuclear power plants in Japan following last year’s earthquake, some scientists have questions about one particular plant.

The article’s headline falsely suggests that the scientists oppose all nuclear power plants, which is not the case. If anything, the overall manner in which the Fukushima power plant withstood the biggest earthquake in history demonstrated that most of Japan’s nuclear power plants are probably safe from future earthquakes. For scientists to have concerns about one particular plant seems reasonable, however, and is not the same thing as opposing all nuclear power.

A skeptic takes an educated look at alternative energy.

A skeptic takes an educated look at alternative energy.

The matter of affordable costs is the hardest promise to assess, given the many assorted subsidies and the creative accounting techniques that have for years propped up alternative and renewable generation technologies. Both the European Wind Energy Association and the American Wind Energy Association claim that wind turbines already produce cheaper electricity than coal-fired power plants do, while the solar enthusiasts love to take the history of impressively declining prices for photovoltaic cells and project them forward to imply that we’ll soon see installed costs that are amazingly low.

But other analyses refute the claims of cheap wind electricity, and still others take into account the fact that photo­voltaic installations require not just cells but also frames, inverters, batteries, and labor. These associated expenses are not plummeting at all, and that is why the cost of electricity generated by residential solar systems in the United States has not changed dramatically since 2000. At that time the national mean was close to 40 U.S. cents per kilowatt­-hour, while the latest Solarbuzz data for 2012 show 28.91 cents per kilowatt-hour in sunny climates and 63.60 cents per kilowatt-­hour in cloudy ones. That’s still far more expensive than using fossil fuels, which in the United States cost between 11 and 12 cents per kilowatt-hour in 2011. The age of mass-scale, decentralized photovoltaic generation is not here yet.

Then consider the question of scale. Wind power is more advanced commercially than solar power, but with about 47 gigawatts in the United States at the end of 2011 it still accounted for less than 4 percent of the net installed summer generating capacity in that country. And because the capacity factors of U.S. wind turbines are so low, wind supplied less than 3 percent of all the electricity generated there in 2011.

Read the whole article. It is detailed, thoughtful, and blunt.

Forbidden by the Forest Service from using powered equipment, a shovel brigade of 60 people last weekend made temporary repairs to Tombstone’s water line.

Forbidden by the Forest Service from using heavy equipment, a shovel brigade of 60 people last weekend made temporary repairs to Tombstone’s water line.

“It took 60 people two days to complete a work project that could have been done in two hours with the appropriate equipment,” Barnes said. “We have a lot more work that needs to be done up there, but we don’t have the permits from the forest service to go back.”

For reasons that only bureaucrats understand, the Forest Service decided that the use of heavy equipment like a bulldozer is more harmful to nature than 60 people with shovels, even though in the end the work done is exactly the same, and that this same work was done repeatedly in the past by heavy equipment.

The IPCC has decided that it is too difficult to purge non-peer-reviewed envionmental activist press releases from its next report.

The IPCC has decided that it is too difficult to purge non-peer-reviewed envionmental activist press releases from its next report. Instead,

[A]ny information they choose to use will be considered peer reviewed just by being posted on the Internet by the IPCC.

In addition, the IPCC has decided “to impose gender and geographical quotas on IPCC membership,” rather than simple pick the best scientists.

And climate scientists wonder why the public no longer believes anything they say.

New data from Antarctica suggests that the south pole icecap is not warming, as predicted by climate models.

12:53 pm

New data from Antarctica suggests that the south pole icecap is not melting, as predicted by climate models.

It turns out that past studies, which were based on computer models without any direct data for comparison or guidance, overestimate the water temperatures and extent of melting beneath the Fimbul Ice Shelf. This has led to the misconception, Hattermann said, that the ice shelf is losing mass at a faster rate than it is gaining mass, leading to an overall loss of mass. The model results were in contrast to the available data from satellite observations, which are supported by the new measurements.

The team’s results show that water temperatures are far lower than computer models predicted, which means that the Fimbul Ice Shelf is melting at a slower rate. Perhaps indicating that the shelf is neither losing nor gaining mass at the moment because ice buildup from snowfall has kept up with the rate of mass loss, Hattermann said.

In other words, the climate models were wrong. When actual data was obtained, first by satellites and now from the water under the ice shelf itself, the new data found that the ice shelf is stable, not melting as predicted.

Global warming: Second thoughts by an environmentalist.

Global warming: Second thoughts by an environmentalist.

For many years, I was an active supporter of the IPCC and its CO2 theory. Recent experience with the UN’s climate panel, however, forced me to reassess my position. In February 2010, I was invited as a reviewer for the IPCC report on renewable energy. I realised that the drafting of the report was done in anything but a scientific manner. The report was littered with errors and a member of Greenpeace edited the final version. These developments shocked me. I thought, if such things can happen in this report, then they might happen in other IPCC reports too.

He then very clearly outlines what we do and do not know about the Earth’s climate, and pinpoints the important uncertainties that presently exist.

A UCLA professor who exposed corruption while also challenging the legitimacy of certain California fuel regulations, has sued the university for firing him.

The McCarthyism of the environmental movement: A UCLA professor who exposed corruption while also challenging the legitimacy of certain California fuel regulations, has sued the university for firing him.

Enstrom charged in 2008 that his colleagues exaggerated the adverse effects of particulate matter in order to justify expensive diesel fuel regulations to the California Air Resources Board (CARB). Enstrom testified in the same year to the state Senate that the lead contributor to the CARB report, Hien T. Tran, paid $1,000 for his Ph.D. from a fake university, and members of a CARB panel had exceeded their mandated three-year term limits by decades.

Shortly after Enstrom revealed the misconduct, UCLA began sending him notices of termination and has refused to compensate him for more than a year’s worth of work….

Tran was eventually suspended for 60 days, and one professor who had served on the CARB panel for 26 consecutive years was removed and later put back on the panel. John Froines, who has publicly supported diesel fuel regulations, was on a committee that voted to dismiss Enstrom.

Read the whole thing. It illustrates why attending UCLA for a science education is clearly a waste of time. They don’t want to teach their students science. They want to teach them propaganda.

The North Carolina legislature has passed a bill that requires its coastal planning commission to ignore the accelerated sea level rise predictions of global warming scientists and instead use more conservative numbers.

The North Carolina legislature has passed a bill that requires its coastal planning commission to ignore the accelerated sea level rise predictions of global warming scientists and instead use more conservative numbers.

To put it another way, North Carolina has decided, for coastal planning purposes, to use the slower linear rise in sea level that can be extrapolated from the actual data that scientists have gathered for the past century, and not use the models pushed by the IPCC and other global warming scientists that predict an acceleration of sea level rise in the next century due to human-caused global warming.

This decision by North Carolina has happened because increasingly people of good conscience no longer believe anything the global warming activists in the climate field are telling them. These scientists either perpetuated scientific fraud to sell the idea of human-caused global-warming, or have been willing to whitewash the fraud of other scientists. Rather than listen to them, the North Carolina legislature has decided to interpret the data independently. The legislature might very well be wrong, but what else can they do? They certainly can’t trust the claims of the climate field.

Off to Nevada

5:00 am

Nevada

For the next seven days my daytime posting is going to be spotty, as I will be in some remote areas of Nevada working on an on-going Forest Service project to inventory and survey caves in an area in the northeastern area of the state. The project is mostly over, but as I have surveyed, sketched, and done the cartography for many eastern U.S. caves, the guy running the project asked if I would be interested in participating. Interested? I was thrilled.

Though we will be in a somewhat remote area, I still hope to post periodically during the week, not only about the usual topics but also about some of the caves we will have surveyed, some of which are rarely visited. I will also try to post some pictures of the spectacular country we expect to visit. (The photo on the right was provided to me by Tom Gilleland, who is running the project.) Stay tuned.

Environmental activists have launched a petition drive to stop SpaceX from building a commercial spaceport in Brownsville, Texas.

1:45 pm

The wrong side of history: Environmental activists have launched a petition drive to stop SpaceX from building a commercial spaceport near Brownsville, Texas.

“I love the space program as much, if not more, than anyone,” said Environment Texas Director Luke Metzger. “But launching big, loud, smelly rockets from the middle of a wildlife refuge will scare the heck out of every creature within miles and sprays noxious chemicals all over the place. It’s a terrible idea and SpaceX needs to find another place for their spaceport.”

This guy obviously doesn’t know that almost all of the Kennedy Space Center is a wildlife refuge, and a successful one at that. But then, what do facts have to do with most environmental causes?

A government study has found that the more educated in science and math an American is the more likely they will be skeptical of the dangers of global warming.

A government study has found that the more educated in science and math an American is, the more likely they will be skeptical of the dangers of global warming.

The results of the survey are especially remarkable as it was plainly not intended to show any such thing: Rather, the researchers and trick-cyclists who carried it out were doing so from the position that the “scientific consensus” (carbon-driven global warming is ongoing and extremely dangerous) is a settled fact, and the priority is now to find some way of getting US voters to believe in the need for urgent, immediate and massive action to reduce CO2 emissions.

Having discovered that educating the public will defeat these activists in their goals, the researchers than suggest, like Paul Krugman, that maybe the U.S. government should stop trying to educate people and focus on fake propaganda instead.

A graveyard of ships in the desert

9:35 am

A graveyard of ships — in the desert.

This environmental disaster in the Soviet Union was caused more by that failed country’s centralized state-run command society than the technological society they were trying to create. Though technology in any kind of society can certainly do harm to the environment, when all decisions are controlled by a single entity — in this case the communist Soviet government — it is practically impossible to adapt and adjust when things start going wrong.

In a free democracy, however, you have many safety valves. No project is ever so big that it effects everything, and if things start to go wrong the chaos of freedom will allow people to choose differently, correcting the problem more quickly.

Climategate continues

Climategate continues.

The article describes more evidence that the tree ring data used by global warming scientists was fraudulently manipulated to suggest a warming in the past half century when the full data set showed no such thing.

Until the climate field cleans house and admits to this wrong-doing, no one is going to trust anything they say.

California officials have confisicated two stuffed animals from a local bar, after being on display for about a half century.

5:01 pm

Theft by government: California officials have confiscated two stuffed animals from a local bar, after having been on display for about a half century.

Both animals, while now endangered, were not endangered when they were killed, stuffed, and placed in the bar. Their existence is completely irrelevant to saving either species. For the government to confiscate them is nothing more than a expression of naked power. Worse, if there was no payment for them it is illegal. The Bill of Rights has this clause that says government cannot take a citizen’s property without just compensation.

As I said, theft by government.

In a paper published today in Geophysical Research Letters, researchers studying an icecore drilled in the West Antarctic Ice Sheet have found strong evidence of the 16th century Little Ice Age in the southern hemisphere.

9:07 am

In a paper published today in Geophysical Research Letters, researchers studying an ice core drilled in the West Antarctic Ice Sheet have found strong evidence of the 16th century’s Little Ice Age in the southern hemisphere. From the abstract:

The temperature in the time period 1400–1800 C.E. was on average 0.52 ± 0.28°C colder than the last 100-year average. … This result is consistent with the idea that the [Little Ice Age] was a global event, probably caused by a change in solar and volcanic forcing, and was not simply a seesaw-type redistribution of heat between the hemispheres as would be predicted by some ocean-circulation hypotheses.

In an effort to emphasis human-caused global warming and eliminate any evidence of climate change caused by other factors, many global warming scientists have argued that the Little Ice Age was not a global event but merely a cooling in Europe. This data proves them wrong. The global climate has varied significantly in the recent past, and not because of human behavior. Other factors, such as fluctuations in the solar cycle, must be considered more seriously for scientists to obtain a better understanding of the Earth’s climate.

A new study has found that the glaciers of Greenland are not behaving as predicted.

1:27 pm

The uncertainty of science: A new study has found that the glaciers of Greenland are not behaving as predicted.

In northwestern Greenland, for example, where most of the glaciers move relatively quickly and flow directly into the sea rather than ending on land, average speed jumped by 8% between 2000 and 2005 and rose another 18% from 2005 to 2010. Nevertheless, the researchers report online today in Science, the glaciers in this region showed no uniform pattern of acceleration. About one-third flowed at the same rate throughout the decade, one-fourth slowed during the interval, and about 15% slowed during the first half of the decade and then surged from 2005 to 2010.

Similarly, many of the individual glaciers in southeastern Greenland don’t follow the region’s overall trend. Although the average speeds for these glaciers increased by 28% over the decade, substantial accelerations by some glaciers were balanced by considerable slowing by others. About 43% of the glaciers in the region sped up between 2000 and 2005, but around 25% slowed down by more than 15% from 2005 to 2010.

In other words, if there is any warming, it hasn’t manifested itself in a predictable manner in the glaciers of Greenland. In fact, the data above suggests instead that if there has been any warming, it either has been far less than predicted, or has had relatively little influence on the Greenland ice sheet.

Cryosat has released its first seasonal variation map, tracking the growth of the Arctic icecap for the winter of 2010-2011.

The video at the link is quite interesting to watch. Note however that the press information says nothing about whether the icecap was larger or smaller than expected, something that probably is not surprising. It will probably take decades of further work to get the true context of these results.
