Joe,
Sea level measurements are now done by satellites. Irrespective of islands growing or shrinking, sea levels are absolutely rising.

And, 40% of the measured rise is due to ocean warming. Most things get larger as they warm. And the oceans are getting warmer because the winds blowing acoss the sea surface are warming. And the air is warming because additional CO2 is reducing the amount of heat energy exiting the earth.

So an energy imbalance occurs because energy leaving the earth each day is less than the daily input if energy from the sun.

Satllites have measured this difference to be about 1 watt per square metre.

This is equivalent to a one thousand watt heater, running 24 hours a day, every day, in a square area approximately 33m by 33m. All over the earth.

Imagine walking around the earth, and feeling the warmth of such heaters, every 33 meters walked.

This heating fully explained in the 1800's.

Unfortunately, even if we stopped creating CO2 by burning fossil fuel tomorrow, earths temperature would continue rising for many, many decades.

And the frequency and strength of extreme events have been increasing over past decades. And farmers suiciding because of lengthy drought in NSW and Qld.

John Hewson understood ramifications of Climate Change decades ago - he took a policy of a full Emissions Trading Scheme to the election he lost. He would have fully implemented it in 2000.

It is real, it is bad, it is getting worse,
and too many politicians and others fiddling their Nero violins.

Thanks, Tony, for trying to teach me how to suck eggs.

"Most things get larger as they warm" ? Except water, between 0 and about 3 degrees Celsius: in that range, it gets 'larger' as it cools. That's why the ice used to pop the top of our milk bottles on a winter's morning when I was a kid.

Conversely, as water near freezing point - as I assume deep-water is - warms, up to about 3 degrees it gets 'littler', that is, it takes up less space, i.e. volume. I suppose that, if they had bottled milk in the old days at just above freezing point, say one degree, the bottle tops might have been sucked in by the time we picked them up.

Have I got that right ?

Joe

Reasonable,
But most of the warming occurs in top 700m ( or thereabouts) and that water expands as it warms.
I needed to get down to sucking eggs as another post queried sea level rising.
Tony.

Hi JF,
You may not know Professor Muller. Hi is very well credentialed physicist who was the poster person for many who denied anthropogenic climate change. But many other physicists agreed with the global warming science.

So he decided to collect his own database of temperature records. With funding from Koch brothers, he assembled his own team of researchers and top statisticians.

You can see/hear the results of his research in this 5 minute video.

Cheers Tony

We have been told sea level is rising because polar and glacier ice is melting. What happened to that story?

A puzzle to me is where CO2 is situated.
Ozone is at the poles.
Oxygen is everywhere.
Where is CO2 located, is it everywhere?

Hi Joe,
I think presently hot winds are linked to warmer than normal water linked to sewage and land use nutrient pollution proliferating algae in the Indian Ocean.
India alone has over a billion people and all waterways run into the Indian Ocean.
I have a sea surface temperature chart showing warmth from the coast of India meanders south and then south west to Indian Ocean waters off southern Western Australia.
Scientists in India know there and many algae blooms in the Indian Ocean, many, I heard reiterated.

If you feed very cold water into a gas heater for a shower the water coming out is not so warm but if you feed warm water into the same heater then water coming out is much warmer, or even too hot for a shower.
The beginning of summer south of the equator is a time when I expect algae to be thriving and retaining warmth.
I think summer onset algae thrives , especially because the N&P nutrient loading has built up during cold winter months, so when warmth arrives there is plenty of nutrient to proliferate algae and thus warm surface waters.
I also think algae would act like a blanket and retain warmth in surface waters, not forever but long enough to sometimes impact climate..

I think when water warms and lifts sea level in the northern Indian Ocean, that higher water has to go somewhere so it spills virtually downhill southward toward the pole.
It’s off SW Western Australia where such warmth can meet cold winds coming up from Antarctica.
Cloud then forms and spills and prevails eastward across the Great Australian Bight, and sometimes hot wind off the Indian Ocean is dragged eastward over the Australian mainland.
I think those winds over the mainland bring the very hot days, they are winds warmed by the Indian Ocean PLUS by hot desert land.
If it was cold wind coming from the Indian Ocean then it would not get so hot while crossing that desert.
