I’ve always been a proud skeptic of the (alarmism on) Anthropogenic Global Warming, and now I’m very happy to fully endorse this recap (Know the Facts - A skeptic’s guide to climate change) from berkeleyearth.org and its main conclusions (my comments in brackets):

  • Stay skeptical (always)
  • Practice and promote energy efficiency (by principles)
  • Recognize that most future emissions will come from China and the developing world (and Science and technology depends on that, and they are the only thing who eventually could save us from a global crisis)
  • Demand sustainable and cost-effective solutions in the US and around the world (yep, pragmatism should be always above politic, and, of course, above science tainted by politics).

So please, do not let that some interested people (or gullible persons or guided by a specific agenda) to use Science (and propaganda) in order to impose damaging policies for everyone in general, and for developing countries in particular. Not in the name of Science, it does not work, Science always win, because…

….reality must take precedence over public relations, for nature cannot be fooled.

I knew that some people would go to bray about this entry:

- “Um, no. Simply wrongheaded and idiotic. Nothing personal, but I pity you…

(I only see idiocy in your comment, in bulk, read the report please)

- “Hey if that makes you feel better about driving your SUV……

wiredclover (and calitony who echoes him) seems not happy with the “pamphlet” because it broke with the (unfounded) alarmism, and probably because does not call “negationist” to skeptics. The fact is that everything in the paper is true (as established data), and everything trying to go farther is or propaganda, or delusions, or pseudoscience… typically a mixture of all three.

To view the state of the art (and debate) on the subject, I recommend to take a look at climatedialogue.org you will see that discussions are due to the uncertainties and ignorance of many mechanisms, and the one who sells certainty there where there is not, is the one who has to explain their arguments, not the people recognizing the uncertainties.

battalio complains that the data (??) are self referring to their own research (not peer-reviewed), totally losing the scope of this paper: a basic compilation of what is known and omitting what is mere speculation.

About the claim “sea levels are going to rise catastrophically” there is no sign of it, and the “catastrophic” rise of sea level already occurred 15,000 years ago as befits an interglacial period:

The chances of a future catastrophic growth in sea level (or not) will depend on our ability to adapt, not of the CO2 emissions, as far as climate sensitivity is quite certainly much less that 3 C per century (IPCC itself has not been able to give a “more likely data”  in the AR5 report, and indeed they decreased 0.5° the lower limit).

Of course there are all kinds of speculation (unverifiable and infansables, ie pseudo-scientific), but analysis of the data leave little room for alarmism.

Also says:

I also hate it when people misappropriate the quotes of scientists with no context, thinking that it will prove their point.

Well, the context was Feynman complaining about politization of science (on the affair of  challenger disaster), I supposed that most of the readers would realize this. And this is the problem of Climate Change “Science”, it is all about politic, and economy, and geostrategy, i.e. is a Social Science with no prediction capacities.

I’m very disappointed in this blog.

I’m sorry on that, but I can do nothing about.

Dear battalio, first of all thanks for your tone. And you’re right, English is not my first language, and maybe that will influence when I try to find the right words to explain my feelings. In any case I’ll try again.

I don’t understand why you don’t like the term “proud skeptic”. Being skeptic on Climate Change is not an easy task (is neither easy nor as a blogger or as a geophysicist), you are exposed to all kind of insults, falacies, and pure lies. And that is why finding a site that clearly explains that we do not deny most of the facts, is already in itself a step forward, and for that reason I have highlighted in Science is Beauty, and affirm that I am proud to be skeptical (no denier).

About sea level I mean that I have linked this paper on purpose because does not displays predictions, shows only trends and acceleration in observations (facts), and everything else are speculations, more or less believable or fundamented, but speculations.

You can’t say (well, you shouldn’t)

"In several centuries we will have a terrible problem." [because the human/because the CO2]

First because you don’t know the emissions 20, 50, 100, 200 years from now. Nobody knows, and nobody knows about the energy mix for these years. Nuclear fusion, new generation of fission, renovable energies… who knows…

Second because even knowing these (essential) parameters, we don’t know several mechanisms on feedbacks and sensitivities… After 150 years of weather our understanding of the climate is better, but we still have essentially a very basic and low predictive reliability knowledge.

Not recognizing this things is to trick people, and trick people is Politics not Science. We have many (real) problems, even human generated problems (pollution, deforestation), and diseases, poverty, wars… to invent other problems based on speculation and admittedly incomplete numerical models.

In short, my opinion is that everything is very exaggerated, politically contaminated, and in the hands of lobbies (falsely) environmentalists and companies of renewable energy (not far of the Big Oil). The Science behind seems too weak to me, so it is absurd speaking of the future with such certainty, is a mirage. Makes me this a monster…? it may be so, but we’ll see who is closer to the truth.

Cheers!

Cassini Spacecraft Reveals 101 Geysers on Icy Saturn Moon

Scientists using mission data from NASA’s Cassini spacecraft have identified 101 distinct geysers erupting on Saturn’s icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon’s underground sea all the way to its surface.

Over a period of almost seven years, Cassini’s cameras surveyed the south polar terrain of the small moon, a unique geological basin renowned for its four prominent “tiger stripe” fractures and the geysers of tiny icy particles and water vapor first sighted there nearly 10 years ago. The result of the survey is a map of 101 geysers, each erupting from one of the tiger stripe fractures, and the discovery that individual geysers are coincident with small hot spots. These relationships pointed the way to the geysers’ origin.

Thanks to recent analysis of Cassini gravity data, the researchers concluded the only plausible source of the material forming the geysers is the sea now known to exist beneath the ice shell. They also found that narrow pathways through the ice shell can remain open from the sea all the way to the surface, if filled with liquid water.

The fact that Enceladus’ sea is salty, laced with organic compounds, spouting into space, and maybe even rising up to the surface has raised this particular Saturnian moon as a major target for future exploration.

Solar Dynamics Observatory captures images of lunar transit

On July 26, 2014, from 10:57 a.m. to 11:42 a.m. EDT, the moon crossed between NASA’s Solar Dynamics Observatory (SDO) and the sun, a phenomenon called a lunar transit. A lunar transit happens approximately twice a year, causing a partial solar eclipse that can only be seen from SDO’s point of view. Images of the eclipse show a crisp lunar horizon, because the moon has no atmosphere that would distort light. This image shows the blended result of two SDO wavelengths - one in 304 wavelength and another in 171 wavelength.
