Climate Change

Earth's climate has been warming and cooling in cycles for milions of years.
Well before man could make a difference.
The evidence is in the ice cores.

In the 70's we were supposedly headed for a new ice age.
Now we are warming up.
The Earth was much warmer, than it is now, in the middle ages around 1000AD.

The cycle seems to be about natural variations in the sun's magnetic field - nothing to do with man.
It seems to be about cloud formation and the amount of cloud cover.
(More clouds reflect more of the sun's energy before it reaches the ground and vice versa.)

But that does not suit the global billion dollar climate change business.
These pseudo scientists tweak their models to come up with ever more extreme predictions - in order to gain headlines and therefore more funding.
N.B. the earth flips magnetic field polarity every few thousand years (north becomes south and vice versa) - the sun also has a natural cycle for the strength and polarity of it's magnetic field.

It is interesting to note that one solution put forward to prevent the Earth from warming up is to seed more cloud cover.
But the connection to that (the amount of cloud cover) being the root cause of climate change is never mentioned in the media.

The other pertinent fact is that C02 levels rise after temperature rises not the other way around - evidenced from ice cores going back 100,000's of years and more recent scientific data.
Liquids absorb less gas when they get warmer.

The Greens have a lot to answer for.
E.G. it will take 200 yrs to get back to equilibrium for the bio fuels initiative - the amount of trees cut down to grow bio fuels vs c02 savings from bio fuels.
The fact that everyone's energy bills are going up to subsidise wind/tidal/solar power.

Bush's directive to grow corn for biofuels was particularly stupid. It is much more efficient to use sugar cane for bio fuels. But you can't grow sugar cane in US.

I do not advocate pollution - so limits on man made toxic emissions shud be made - but not the hysteria of the climate change bozos.
Pollution affects general health.

If there was a serious initiative to move towards renewables we would build a solar power field nearly a million sq miles big in the Sahara and pipe the power to Spain and from there into the general European network. But the Arabs would not like the effect on the price of oil and would object to this construction in their back yard.
Or a huge solar power field could be built in Central Spain or Southern California, or Arizona or Nevada or Texas.
Instead of this we now have Obama subsidizing solar panels in places like Wisconsin and Pittsburgh and putting up everybody's tax and energy bills as a result.

The relative cost of infrastructure to pipe the power from numerous remote wind/tidal locations is huge.
It would be negligible for the Sahara.

N.B. Henrik Svensmark thinks the Earth's temperature reached a peak around 2009 and is now set to start  a period of cooling. We shall see.
