Yep, the next Nemo film should be called "Finding Bertrand".

Fact, science or fiction? :?

The arctic seaice is simply ice floating on top of the water. There is no land under it only water and currents. So the ocean currents have a lot of influence on temperature.

Changing obliquity means more exposure to sunlight. The land in those latitudes gets warmer but doesn't go anywhere ('cos its fixed).

However the water can (and does). It flows up towards the artic circle and under the ice.

It warms the ice and what does ice do when its being warmed do? it melts.

The argument is NOT about if the climate is changing and parts of earth are getting warmer or cooler.

The argument is about whether its mankind that's causing it or a natural long term cycle.

Science can measure temp changes here and temp changes there until the cows come home. All they'll tell is that temps are changing.

No argument about that.

If science puts as much effort into researching alternative explanations (I'm just quoting one) as it has in making money for the people/organisations who have financial and social interests in the subject, we'd ALL be better served as science is supposed to do.

Climate change now has beneficial dynamics..

Islands are probably getting bigger from accrued plastic, anyone who has seen a remote beach that doesn't get litter regularly removed will know this is not as silly as it sounds :D

Climate change......... Earth's axial lean...........Milankovitch Cycles

Have a look at the link which explains wind patterns on the earth's surface.

Note the presence of 3 bands on the surface of the earth.

Hadley cells, Ferrel cells and Polar cells.

Hadley cells exist around the equator down to about 30 degrees south. Roughly from equator to Brisbane/ northern NSW.

Ferrel cells exist roughly 30 degrees to 60 degrees south. Brisbane/northern NSW to south of Tassie.

Polar cell is pretty obvious. 60 degrees to 90 degrees (South Pole).

The wind patterns in each cell determine the climate.

As the tilt of the earth changes, the positions of the edges of these cells changes on the surface of the earth.

A change in the positions of the edges causes changes in the wind patterns which in turn causes changes in the climate within that particular cell.

The edges aren't abrupt. Their positions are broad so the effect of the changes in wind patterns (and thus changes in the climate within the cells) are spread over greater areas along the edges.

Some of these changes can easily be seen and predicted as they are annual events brought about by the relationship with the sun as the earth orbits. The earth's orbit produces 4 distinct seasons in a year. Summer, autumn, winter and spring.

The timing and intensity of these seasons are in turn brought about by the angle of the earth's axis (currently about 23.5 degrees).

That angle is called obliquity.

So.....change that angle (obliquity) and you change the positions of those cells on the earth's surface. The wind patterns on the earth's surface change as the cell positions change and we have climate change.

The earth's slope/angle/obliquity is changing in a cycle of 41,000 years.

Currently, we're at about 10,000 years into the current cycle so the rate of change in position of the bottom of the Hadley cell is at its maximum. Its heading north.

To give an idea of how much the position of the southern hemisphere Hadley cell changes, at zero years with the change at max, the Tropic of Capricorn is down near Bundaberg.

21,000 years later, the Tropic of Capricorn will be located between Rockhampton and Mackay.

So the change in wind patterns will bring climate change to places within that Hadley cell (particularly in a area around the southern edge).

Ditto with the Ferrel cell (south of the Hadley cell). It's position (including the edges) will change also.

Once again, changes in wind patterns will bring climate change within the Ferrel cell (particularly around the edges).

The Ferrel cell covers Aus roughly south of NSW north coast right down to well south of Tassie which is 43 degrees S( 1000 miles further south).

As the Ferrel cell moves north, Vic, southern NSW, SA and WA will start to experience climate similar to what Tassie gets.

So have a look at the guy with the blackboard and chalk on the link. Note the Hadley, Ferrel and Polar cells with their effect on wind patterns within the cells (particularly along the edges).

What the guy with the chalk has given you is based on no tilt of the earth's surface. Easier to explain.

Lean that axis by 23.5 degrees and the cell positions change as do the wind patterns and resulting climate.

At a lean of 23.5 degrees we have the current situation.

Learn that axis even further (due to the 41,000 year obliquity cycle) and we have the earth with an everchanging climate including ice ages, formation of deserts etc).

Of interest, because the earth's lean is constantly changing, the position of the Tropic of Capricorn is changing every year. Its moving north at about 11 metres per year at the moment. Fastest movement north in the current cycle. Ditto for the Tropic of Cancer. Its moving south at 11 metres per year.

So the Tropic Zone is becoming smaller by 22 metres per year.
Over a couple of thousand years, do we think that will change the climate at places within that zone. Or the temperate zone?

In 10,000 years time, the Tropic will be near Clairview and turning around so there will be a slowing down in the rate of climate change.

As it heads south the fastest rate of change will be around Rockhampton in 20,000 years from now (back up to 11 metres per year change but now heading south). Why around Rockhampton? Because Rockhampton is about the midpoint of the range of Tropic of Capricorn end locations (Clairview/Bundaberg).

Check out the cycles of Ice Ages. They're also related to axial tilt PLUS a couple of other effects which cause Ice Age "planets to align".

These natural climatic changes have been going on for hundreds of thousands of years. Mankind has only been doing stuff for 200 years.

What our climate change alarmists are saying is that the rate of climate change is happening fast and MUST be because of mankind.

Change is certainly happening fast but its because the 41,000 cycle is in its 10,000 year "fast phase" which is the fasted changing period. So....the science ain't settled at all.

Here's a story about a cleaner at a Scottish university (James Croll) who changed the world of science.

He worked out the science associated with ice ages and climate change in the mid 1800s.

His work was later taken up and refined by........Milankovich (7.56 mins into video).

A truly remarkable story.

I have quiet a lot of science on this topic that shows the "extreme" weather has not increased in relation to the historical record.
Insanity is a good place to hide from reality!

It is not how long the fish is but how long you have fished & how long you've wished.......
