New Studies Flip Climate-Change Notions Upside Down

Cold Sun Rising

Sam Khoury writes: The sun will go into “hibernation” mode around 2030, and it has already started to get sleepy. At the Royal Astronomical Society’s annual meeting in July, Professor Valentina Zharkova of Northumbria University in the UK confirmed it – the sun will begin its Maunder Minimum (Grand Solar Minimum) in 15 years. Other scientists had suggested years ago that this change was imminent, but Zharkova’s model is said to have near-perfect accuracy.

So what is a “solar minimum”?

Our sun doesn’t maintain a constant intensity. Instead, it cycles in spans of approximately 11 years. When it’s at its maximum, it has the highest number of sunspots on its surface in that particular cycle. When it’s at its minimum, it has almost none. When there are more sunspots, the sun is brighter. When there are fewer, the sun radiates less heat toward Earth.

But that’s not the only cooling effect of a solar minimum. A dim sun doesn’t deflect cosmic rays away from Earth as efficiently as a bright sun. So, when these rays enter our atmosphere, they seed clouds, which in turn cool our planet even more and increase precipitation in the form of rain, snow and hail.

Solar cycles

Since the early 1800s we have enjoyed healthy solar cycles and the rich agriculture and mild northern temperatures that they guarantee. During the Middle Ages, however, Earth felt the impact of four solar minimums over the course of 400 years.

The last Maunder Minimum and its accompanying mini-Ice Age saw the most consistent cold, continuing into the early 1800s.

The last time we became concerned about cooler temperatures – possibly dangerously cooler – was in the 1970s. Global temperatures have declined since the 1940s, as measured by Pacific Decadal Oscillation. The PDO Index is a recurring pattern of ocean-atmosphere climate variability centred over the Pacific Ocean. Determined by deep currents, it is said to shift between warm and cool modes. Some scientists worried that it might stay cool and drag down the Atlantic Decadal Oscillation with it, spurring a new Ice Age. The fear was exacerbated by the fact that Earth has been in the current inter-glacial period for 10,000 years (depending on how the starting point is gauged).

If Earth were to enter the next Ice Age too quickly, glaciers could advance much further south, rainforests could turn into savannah, and sea levels could drop dramatically, causing havoc.

The BBC, all three major American TV networks, Time magazine and the New York Times all ran feature stories highlighting the scare. Fortunately, by 1978 the PDO Index shifted back to warm and the fear abated.

By the 1990s the UN’s Intergovernmental Panel on Climate Change (IPCC) had formed the “97 per cent consensus”. The consensus was that Earth was warming more than it should, not just due to natural causes but also human activity. This was termed Anthropogenic Global Warming. The culprit was identified as carbon dioxide generated from the burning of fossil fuels. Read the rest of this entry »


Chaos on the Coast: How Drought and Fire Ravaged North America’s West Coast 

The recipe for drought is simple: mix extended hot weather with a corresponding lack of precipitation and, voilà. Add in a carelessly tossed cigarette or a flash of lightning and drought conditions beget wildfires. Both have wrought damage and pain on North America’s West Coast during the summer of 2015.

Vanishing of Polar Ice is the Result of Runaway Global Warming REVISED: Data Manipulated

 Data Systematically ‘Adjusted’

 writes: When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.

Two weeks ago, under the headline “How we are being tricked by flawed data on global warming”, I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been recorded. In each instance, the actual trend of 60 years of data had been dramatically reversed, so that a cooling trend was changed to one that showed a marked warming.

Unknown

This was only the latest of many examples of a practice long recognised by expert observers around the world – one that raises an ever larger question mark over the entire official surface-temperature record.

Following my last article, Homewood checked a swathe of other South American weather stations around the original three. In each case he found the same suspicious one-way “adjustments”. First these were made by the US government’s Global Historical Climate Network (GHCN). They were then amplified by two of the main official surface records, the Goddard Institute for Space Studies (Giss) and the National Climate Data Center (NCDC), which use the warming trends to estimate temperatures across the vast regions of the Earth where no measurements are taken. Yet these are the very records on which scientists and politicians rely for their belief in “global warming”.

Homewood has now turned his attention to the weather stations across much of the Arctic, between Canada (51 degrees W) and the heart of Siberia (87 degrees E). Again, in nearly every case, the same one-way adjustments have been made, to show warming up to 1 degree C or more higher than was indicated by the data that was actually recorded. This has surprised no one more than Traust Jonsson, who was long in charge of climate research for the Iceland met office (and with whom Homewood has been in touch). Jonsson was amazed to see how the new version completely “disappears” Iceland’s “sea ice years” around 1970, when a period of extreme cooling almost devastated his country’s economy.
