The Climate (not weather) Thread

[Lost Leopard Spot]

I believe in climate change, things sure are becoming different but not for one minute do I think it's down to human activity. There's a whole industry been spawned by global warming which has now morphed into climate change because people started to doubt it more so when the bloody tree huggers jumped on board.
Me, from what little I know reckon it's down to the sun and our orbits of it, we don't go round in a perfect circle so surely we get closer fom time to time and being humans are a milli second of the earts life how the devil do we know it ain't happened before?
By the same score we drift further away it gets colder add to that the earth is tilting on it's axsis then no wonder the weather patterns are changing.

Astronomically interesting, Hoboh. I believe that with an imperfect orbit we do come closer to the sun from time to time - however, this is not on a geological time scale but once a year. As for the tilted axis, this is why we have winter and summer. This happens every year too.

Precession of the equinoxes come into it to, tbf but on a 40,000 year cycle or thereabouts.
But once more, globally, stuff is happening. If you want to deny it, you're not alone. If you don't deny it, but deny it's you that's causing it, that's even more widespread, and if you think it's fine, then fine, but somebody soon will suffer as a consequence, if you don't.

Not denying it, just p*ssed the governments worldwide jumped on a new way to fleece everyone of their hard earned and the difference it will make ....?

Why are we getting all these sinkholes just now? I assume it'll be to do with the water table, but then that's full of water anyway. Spotty?

sinkholes are usually a consequence of undetected leaks that have undermined solid structures, like roads, above. They wear away, usually for years, but tend to collapse after hydraulic pressure lifts and fractures the solid ground under the pit. Weather like this is ideal for exposing decades old sinkhole pits.

Important to stress the reason the tilt causes winter and summer is not, as often thought, because one hemisphere is *nearer* the sun, as the difference made is pathetically small on the scale of how big the earth is, and how far away from the sun. The cause is in fact the *angle* as the hemisphere pointing towards the sun gets more 'direct' sun light, and less is deflected away by the atmosphere. Hoboh's theory sounds very sus to me as, as you say, the orbit is once per year.

Ah so you know all about and understand events up in the great yonder then
You see none of this takes account of the effects of black holes and other matter over which we know less than Freedman does about wining football matches.
I defy anyone to say our orbits of the sun are perfect and exactly the same route year in year out nor that the earths tilt ain't shifting by the odd degree out the ordinary.

hobo has a point here

[Hoboh]

Milankovitch theorized that the inclination of the Earth’s axis is not always 23.5°. There is a bit of wobble over time. He calculated that the tilt changes between 22.1° and 24.5° within a cycle of about 41,000 years. When the tilt is less, summers are cooler and winters milder. When the tilt is greater, the seasons are more extreme.

The Shape of the Earth’s Orbit around the Sun

The second factor studied by Milankovitch is the shape of the Earth's orbit around the Sun. It is not quite circular. The Earth is a bit closer to the Sun at some times of the year than at others. Slightly more solar energy is received when the Sun and Earth are closest (the perihelion) than when they are farthest apart (the aphelion).

But the shape of the Earth’s orbit is also changing on cycles of between 90,000 and 100,000 years. There are times when it is more elliptical than it is now, so the difference in solar radiation received at the perihelion and aphelion will be greater.

The perihelion currently occurs in January and the aphelion in July. This serves to make the Northern Hemisphere seasons a bit less extreme since the extra warming effect is in the winter. In the Southern Hemisphere the seasons are a bit more extreme than they would be if the Earth’s orbit around the Sun were circular.

The fact that we haven't been here for every second of the Earth's existence without even questioning the recording standards of earlier historians and scientists, means that whatever is suggested can quite be met with scepticism.

All I'm trying to say is there is feck all we can do about it accept adapt to the conditions.
Certainly paying 'green taxes' or giving 'overseas aid' to stop some Somalian cows farting won't make a jot of difference.
Tree huggers are worse than Dick Turpin!

India and China building x-many coal plants a year will piss all over our plans to be green.

There was a documentary on about sinkholes in Florida a couple of weeks ago. Acid rain soil erosion was one of the major issues.

Sorry, may I correct an error?

The Department for Energy and Climate Change spent £15million to curb the flatulence of Colombian cows

I apologise to the Somalian cows.

Salmon farmers in California (a 2 billion dollar industry) are having to transport the spratling Chinook salmon by road due to a three year drought, the worst in history, having dried up the rivers so much that they no longer exist. If rain doesn't occur soon the trucking exercise will be redundant as the fish will no longer have a river to home in on and Californian salmon will be extinct. (I can already hear the anti-tree hugger bollix about this being just weather heading my way).

I don't know. Does it make a difference? Providing of course that it will be no colour at all if they die out.
