When the ice age starts…….

May 12, 2013

Probably the first indications that an ice age has begun will be with a series of long winters – not necessarily the coldest – together with late springs and cool summers. The key factor will be that snow from one winter remains and does not melt before the next winter brings more snow. It will therefore be successions of long winters and cool summers which will allow for the sufficient accumulation of snow and the growth of the area under snow cover. Cold winters and heavy snowfall can surely help but it it is the accumulation of snow from one year to the next which will determine. Old snow will become ice. For negative feedbacks to be triggered the surface area covered by snow and ice must be sufficient that – say – the albedo of the northern hemisphere is altered such that the amount of solar radiation being reflected is itself increased and the surface area under snow/ice cover increases.

Not that I am suggesting that this years long winter is the start of an ice age. Weather is not climate. But ice advancing into the gardens of lakeside homes from Lake Mille Lacs is just another reminder of the power in water (whether in the waters of the tsunami in Japan or as in this ice moving onto land from a lake).

While ice fishing is still going on in some parts of Minnesota, other parts are having what looks like glacier advance in the back yards that is damaging some homes.

As for climate change worries, you can always figure out ways to keep cool, but getting out of the way of an advancing glacier is no easy task as this video shows. Watch this video of what happens in an “ice out” from the nearby lake Mille Lacs, you can actually watch the ice advance. In a matter of minutes the wind pushes the ice about 15 feet from the shore to the doors and windows of lakeside homes.

While this isn’t the same mechanism as ice-age type glaciation, it is fascinating to watch.

The climate is a-changin

April 20, 2013

The winds of climate are changing direction – again.

Forty years ago “climate scientists” were sure we were entering a new ice age and even that we could have triggered the end of the current inter-glacial.

For forty years we have seen the growth of the global warming meme and the demonisation of carbon dioxide and of all things “fossil”.

A new economy based on the expensive and premature cessation of the use of fossil fuels took shape. All alternatives to fossil fuel – no matter how expensive or impractical – were worthy of subsidy. By invoking a connection to global warming any science project could attract funds. A fascist and authoritarian “environmental” politics gained ground.  The politicians had a new “label” for introducing taxation in the name of controlling climate (!). Vast new revenue streams of taxes and subsidies and carbon credits were created in the name of protecting the planet. In fact the penalty for not being “politically correct” on climate was seen as being so disadvantageous that every product – from toothpaste to children’s toys to aircraft and weapons – had to show that it was “climate-smart”. Meaningless new parameters like “carbon footprint” entered the vocabulary. No self-respecting newspaper or scientist or politician or business could afford to be heretical with respect to the new religion of the day.

But the Earth and the Sun and the resulting climate pay little attention to the puny efforts of man and dance to their own music. When an ice age is to come it will come and when the ice sheets are to retreat the earth will warm and humanity’s best option is to adapt to the changes as they come. If we understand anything about the Sun and its cycles, an ice age will surely come – whether in 10 or 10,000 years.  And we should concentrate on having the wherewithal to cope when it does. To attempt to control the climate has more than a hint of arrogance. We might as well try to ask the Sun to shine a little less brightly or for a little longer!

But for the last 17 years (or 12 or 18 depending upon how religious one is) global warming has stalled. Now vast amounts of a “new” fossil fuel – shale gas –  have been discovered and its utilisation is changing the economic landscape. “Global warming” was renamed to be “climate change”. The money making (for some) revenue schemes and subsidy-milking for unnecessary and expensive renewable energy have been revealed for the scams they are. Heretical views are being expressed again.

The climate winds are changing:

  2. A sensitive matter

  4. Global warming: time to rein back on doom and gloom?
  5. Climate scientists struggle to explain warming slowdown

Baby elephant prepares for the coming ice age

January 25, 2013

Their subcutaneous fat layer allows elephants not to freeze, even with this weather. And when the ice-age comes we will have woolly elephants before too long.
