Largest ancient meteorite impact found?

The uncertainty of science: Scientists doing geothermal research in Australia have discovered evidence of what they think is the largest known impact zone from an meteorite on Earth.

The zone is thought to be about 250 miles across, and suggests the bolide split in two pieces each about 6 miles across before impact. The uncertainty is that the evidence for this impact is quite tentative:

The exact date of the impacts remains unclear. The surrounding rocks are 300 to 600 million years old, but evidence of the type left by other meteorite strikes is lacking. For example, a large meteorite strike 66 million years ago sent up a plume of ash which is found as a layer of sediment in rocks around the world. The plume is thought to have led to the extinction of a large proportion of the life on the planet, including many dinosaur species.

However, a similar layer has not been found in sediments around 300 million years old, Dr Glikson said. “It’s a mystery – we can’t find an extinction event that matches these collisions. I have a suspicion the impact could be older than 300 million years,” he said.

In other words, they find some evidence that an impact occurred, but not other evidence that is expected to be found with such an impact. Moreover, the rocks at the sedimentary layer where the impact is found are dated around 300 million years ago, a time when no major extinction took place. Either this impact didn’t really happen, or it didn’t happen when it appears it should have, or it shows that large impacts don’t necessarily cause mass extinctions.

Australia’s climate agency admits to fudging climate data

The Australian Bureau of Meteorology (ABM) has finally admitted that it alters the temperatures recorded at almost all the official weather stations in Australia.

They claim that these adjustments are necessary to make the readings more accurate.

Using a process it calls homogenization, ABM has replaced actual temperature measurements with massaged numbers. ABM claims anomalies have arisen in both the historical data and current measurements due to a wide variety of factors unrelated to climate, such as differing types of instruments used, choices of calibration or enclosure and where it was located, and the closure of some stations and opening of others. The ABM argues such factors justify homogenization of the numbers.

Yet somehow, all the adjustments make the present readings hotter and the past readings colder, thus accentuating the illusion of global warming. Nor is this surprising, as the head of ABM has publicly stated his firm belief in global warming, as noted in the article above.

So, shut up and trust their judgment! When they tell you to give up your cars and nicely heated homes, it is just because they want to save the planet.

Cooking the climate numbers in Australia

A comparison of the raw climate data with the adjusted numbers released by Australia’s Bureau of Meteorology shows that the adjustments have routinely turned the trends from cooling to warming.

This is the same finding that Steven Goddard and others in the U.S. found when they did the same comparison of NASA and NOAA numbers. In every case the adjustments either cooled the past or warmed the present in order to accentuate the appearance of a warming trend, sometimes in complete contradiction of numbers that had been accepted by scientists for decades.

So, does this mean the climate isn’t warming? No. What it means is we haven’t the slightest idea what’s happening, since the data has now been corrupted so badly that it is almost meaningless.

When fully built, the Titanic II will be 270 meters (886 feet) long and capable of holding 1,680 passengers. By modern standards, this is actually fairly small for a cruise ship, especially when compared to newer passenger liners like the behemoth Oasis of the Seas, which measures 360 meters (1,180 feet) long and can hold 5,400 guests.

The Titanic II is set to make the same maiden voyage as the original, traveling from England to New York, by late 2016.

Evidence from a cave in Australia suggests that humans were doing deep sea fishing more than 40,000 years ago

New evidence from a cave in Australia suggests that humans were doing deep sea fishing — with the sophisticated maritime skills such ocean-going requires — far earlier than previously believed, as much as 42,000 years ago.

The science remains uncertain

Two papers published this week by the American Geophysical Union once again indicate that the science of climate change remains exceedingly uncertain. More significantly, the models that try to predict the future of the Earth’s climate continue to appear unreliable, with such large margins of error that it is at this time foolish to make any policy based on their predictions.

The first paper took a close look at the deep water currents in the Atlantic to see if it could track changes to what the authors’ call the Atlantic meridional overturning circulation (AMOC), more generally referred to as the Atlantic conveyor belt. This conveyor belt begins with the sinking of salty dense water in the northeast Atlantic off of Europe and Africa. The deep water current then travels south and into the Indian and Pacific Oceans where it comes to the surface only to flow back to the Atlantic, traveling north along the coast of North America as the Gulf Stream, bringing with it the warm temperatures that make Europe’s climate much warmer than its latitude would normally suggest.

According to most global warming models, higher temperatures should cause the glaciers in the Arctic and Greenland to melt, thereby pouring an increased amount of fresh water into the North Atlantic. This infusion of fresh water is then expected to lower the salinity and density of the Atlantic water, thus preventing it from sinking and thus acting to slow the conveyor belt, and possibly even causing it to shut down. The consequence would be no more Gulf Stream to warm the climate of Europe.

In other words: Disaster! Death! Destruction! All caused by global warming!

Unfortunately for these global warming models, the paper above found no trend at all. The conveyor belt is not slowing, as predicted. To quote the paper’s abstract:
