What Climate change?

Nor me. You can't carve rotten wood.

I can think of something else you could do with it

This is a very good analysis showing how CO2 goes up and down each year following ocean temperature.

Global Warming Causing Carbon Dioxide Increases: A Simple Model « Roy Spencer, PhD

it is indisputable that the amount of extra CO2 showing up at the monitoring station at Mauna Loa, Hawaii each year (first graph below) is strongly affected by sea surface temperature (SST) variations

If most of the CO2 increase year on year was due to man you would see it steadily rising not going up and down in synch with the annual variations of ocean temperature.

Think....warm coke bottle fizzing.

and then imagine what might happen if the sun goes quiet and the oceans start to cool, think about the coke bottle.

It would be fascinating to see how the "Green Brigade" would react if there was a drop in ocean temperature (think record low sunspots) and the CO2 started to decrease.

BB says that temps rise followed by a big increase in CO2
pj says that CO2 rises followed by a big rise in temps


the record shows that CO2 has risen dramatically but temperatures have stayed level for over 18 years.
but temperatures DID rise fast about 20 years ago.

it's clear as day, BB is right

You mean the rate of change is affected by Sea Surface Temps. Nothing controversial about that. But there is also Henry's Law which tells us that as the partial pressure of CO2 will also affect the flux.

If most of the CO2 increase year on year was due to man you would see it steadily rising not going up and down in synch with the annual variations of ocean temperature.

But that is exactly what we do see.



Spencer's 'model' is laughable. He represents the relationship between delta CO, delta T as

∆[CO2]/∆[t] = a*SST + b*Anthro

and then manually experiments with a and b until he gets a curve that fits. As emissions and SST are related there is a multitude of values that will give the 'right' answer so such an approach is prone to bias, conscious or not. A statistical regression is more objective, but unfortunately for Woy, gives a rather different answer:

Roy's Risky Regression

We know the rise in CO2 is manmade from two independent lines of evidence. Firstly, we have good carbon accounting, we know with good accuracy how much CO2 has been emitted, and its enough to raise concentrations to upwards of 500ppm, the fact that the actual rise is smaller indicates that the biosphere, oceans and other sinks have soaked up some of the emissions. Secondly, carbon from manmade sources has a different isotopic signature to natural and the ratio has changed in exactly the way we'd expect if the increase is from human activity.

RealClimate: How do we know that recent CO2 increases are due to human activities?

You're trolling. Nobody could be that dumb and hold down a job in IT.

You're trolling. Nobody could be that dumb and hold down a job in IT.

but in spite of that the warmists are losing the argument

Climate Alarmists fighting a losing battle: Nearly Half Of Young Americans Are Climate Skeptics | Watts Up With That?

young Americans are often unsupportive of government measures to prevent climate change that might harm the economy. Less than a third of those surveyed agreed with the statement, “Government should do more to curb climate change

When the "Green Brigade" are pensioners banging on about Global Warming they'll just be viewed as a "slightly idiotic old fogeys"

Climate change is on the way out as a religion.

[BlasterBates]

Look at all that thick ice

[minestrone]

I wonder if there is a climate change forum online where everyone is pretending to be an expert on IR35 and hadoop.

[EternalOptimist]

You're trolling. Nobody could be that dumb and hold down a job in IT.

You know you have scored a hit when they attack the person rather than the argument.


plus, you know they have laid a cable when they edit their posts constantly.


Is it true that 97% of pj's posts are revised historically.

most of the historic temp records are revised
most of their absurd predictions are revised
most of pjs posts are revised

why cant they get it right first time ?
