The Truth About Global Warming?

The sun for some reason is getting hotter. Much hotter in fact than it was to be expected. Across the globe children today paint a white sun - we were painting yellow suns back in my youth.

According to the New Scientist (will look up article for reference) warming over time enormously increases CO2 in the atmosphere as it has done several times over in previous geological eras. It had likely become a feedback already. The output of this circuit is presently small but may grow rapidly. On this both deniers and Global Warming supporters agree.



Another point of agreement it seems is that a huge amount already in the atmosphere has been caused by human activity. Where the two party don't agree is what may be the primary cause of runaway CO2 increase. Warming of the sun - as the entire solar system moves onto higher energy plains in our galaxy - or the industrial level output of humans.

My take is that this Warming - however inconvenient - comes at a crucial point. For years, we have ignored that Earth resources have been over consumed. (Check out my other blogs on the subject.) If we don't stop that practice, we will surely keep adding to the warming feedback circuit by the virtue of unmitigated economic growth. And again, this feedback circuit is directly coinciding with major climatic changes in Earth weather system -- a point that both deniers and supporters agree on.

So the truth about Global Warming is that no matter how unpredictable the final outcome may be, that one of the very first steps of intervention should aim at evening out consumption between nations of the opposing ends of the production chain. Out of mutual interest, these nations will likely be willing to agree on similarly mutual CO2 targets. (See my other recent post on forced Population Reduction - the planetary alternative that has a different approach to life altogether.)

Electric Sun Brightening

The cause for the Electric Sun is a very interesting one. Today I gave some serious thoughts to so called climate change sceptics or global warming sceptics as labelled in the media. And I came away with a mixed bag of thoughts.

The predominant among them is the consequence of an electric weather system on Earth caused by the activities of an ELECTRIC Sun.
But close second is that 'sceptics' don't seem to deny that something is profoundly changing. Instead, they emphasise two plausible axioms: (1) Changes may NOT be irrevocable; and (2) We humans may not contribute to the current rapid climate change as much as we think we do.

In other words, vast greenhouse component in the atmosphere in the past may have been the consequence of global warming and not the cause. Indeed, just thawing permafrost alone could have contributed to a runaway warming that stopped the Gulf stream so many times in the past and in the end triggered ice ages. The cause? Electric Sun proponents possible answer: Vastly increased Sun activity out of literally nowhere. And it comes and goes they say.

We still need to become self-sufficient, as the current overconsumption of Earth is tragically unsustainable. The last time I looked the US was 9-11 times overconsuming Earth's resources per capita. Even Switzerland was overconsuming it 5 times. This means that if the rest of the world would be consuming so hard and fast, we would need 5-11 Earths every single year to meet those demands.

Make no mistake. We WILL run out of affordable oil pretty soon, then gas, then a little later coal. Global warming is occurring and it WILL dramatically reduce the amount of potable fresh water. And we DO contribute to it with all the greenhouse gases that we emit in rapidly increasing quantities.

The only thing different with a view to a vastly brighter Electric Sun is the Sun's contributions to our unfolding drama. But it IS playing out at a scale that is indeed planetary.

If it is any consolation they say, ALL the planets are warming up. And our Sun HAS become vastly more bright in the past decades literally out of nowhere. It was expected to be more intense as the 11 year clockwork period for it has come. But NOT as much as it is NOW.

The Sun in recent decades must be channeling OTHER energy they say, we don't know what kind.

We also don't know, they say, to what extent out weather is electric in nature. But if so, which is not proven but increasing hypothesised, our climate including perhaps the more intense El Nino Southern Oscillation (or ENSO) is a much more a consequence of a so much brighter and more intense electric Sun then previously thought.

Do we need to prepare for a change. Oh yes. Is it going to be big? Oh yes. Will it take at least a millennium (1000 years!) for things go back to normal? You bet! (For instance there may be at least a 1000 years natural delay in the feedback between the Atlantic and the Southern Pacific thermohaline circulation.

So what's the difference between what scientists labelled 'sceptics' say from the vantage point of an Electric Sun. Nothing in terms of what we need to do to slow our appetite and change to renewables. But the difference is big in terms of our guilt and inability to change things back.

Because what they say is that (a) We are not guilty as charged - the Sun is the culprit; and (b) no matter how hard we try, we cannot work against the Sun and hence cannot change climate back.

Quite a food for thought. And the fact that we should not be shameful for all of the current changes as they say is a helpful ploy to ACT. Indeed, it would be so much easier without guilt.

Sceptic Gets Mired in Controversy

Well known Global Warming sceptic Professor Bob Carter gets a fair hearing and gets into trouble. He got more than flashy soundbites to elaborate on his position. He got himself against a mighty listener: Dr Stephen Schneider. All we ask that Mr Carter should also listen. To himself.

So hear Mr Carter out. In introduction, his position is that putting Carbon Dioxide (CO2) into the air is like putting coats of white paint on a house. The first quantum (layer) will reflect most of the sunshine and consecutive layers - no matter how many - will not add much more to the reflectivity. Similarly, he says, doubling CO2 is causing most of the warming and consecutive outputs are not that big of a concern.

He supports his argument by saying that warming should be seen on a very long time horizon measured in hundreds of thousands perhaps millions of years. He argues these are processes of geological length. And than he turns around and says, a shining fact to support him is the fact that in the past 3-5 years warming that is more than the background noise warming (we don't know what he means by that and he does not elaborate) has not increased.

Well done Mr Carter. No one needs to argue with you if you defeat your own argument. Twice.

First: How historic long term is 3-5 years? Probably not much.
Second: If most of the warming is caused by the doubling of CO2 and not the consequtive outputs and changes are locked in for 30-40 years already (a consensus reached by scientists of both side of the barrier) than we should worry probably even more about the destructive nature of CO2 and its effects on the whole eco - AND biosphere.

It appears that it was a noble intention on his part to broaden the definition of change - not just weather change. But Mr Carter ran into a formidable opponent in Dr Stephen Schneider. While Mr Carter is certainly an able proponent of possible changes on the geological time-scale (himself being from the Marine Geophysical Laboratory, James Cook University.)

Professor Schneider is offering advice to help scholars communicate more clearly with the media and policymakers.
Mr Schneider however is a person monitoring really broad interdisciplinary consequences. Mr Schneider being Melvin and Joan Lane Professor for Interdisciplinary Environmental Studies Department of Biological Sciences, Stanford University, he appeared to be an able advocate of very long term processes including biological ones.


To sum up ...

Allow me just two final figures to contemplate.

If animals or plants go extinct because of too high stress on their respective habitat, what goes with it is what took evolution about 25 million years of perfecting those species to that habitat. A new, drastically different habitat might take similarly long geological time spans to have a new biosphere similarly adopted.

Scientist have reached consensus and agree that ocean surface level rise is mostly due to heat expansion that is about to go on for a thousand to two thousand years.

Both are very long time spans indeed.

So what's the point of arguing consequtive CO2 emissions (that is happening today) if what is already there is so damaging for the very long term, indeed.

Congratulation to Phillip Adams of ABC Radio National LNL for convening such an informative debate and big cheers to story producer Jane Shields.
