It's never rained in Paraguay or been dry in India or RSA. Interesting. Maybe this is proof of this global warming about which you speak. In other news - it will snow here this week.
Carbon Emission Rate On Earth Unprecedented Since Dinosaur Extinction By Alyssa Navarro, Tech Times | March 22, 8:13 AM "About 10 million years after the dinosaurs went extinct our planet experienced a surge in the concentration of carbon dioxide in the atmosphere - a climate event called Paleocene-Eocene Thermal Maximum (PETM). "No one is certain what caused the PETM, but the event had turned temperatures to rise to 5 degrees Celsius (41 degrees Fahrenheit). The Earth continued to warm rapidly, and marine organisms went through die-offs because of ocean acidification. Examining The Past "Today, scientists often look to the PETM as an analog for current rising temperatures. In fact, a new study suggests that humans are putting more carbon into the atmosphere at a faster rate than what happened during the PETM. "Lead researcher Richard Zeebe, an oceanographer from the University of Hawaii, Manoa, said ecosystems need time to adjust. "We're doing it faster and most likely the consequences are going to be more severe," said Zeebe. "Zeebe said that the only event they know at the moment that had a massive carbon release at a short period of time was the PETM. "We actually have to go back to relatively old periods, because in the more recent past, we don't see anything comparable to what humans are currently doing," he said, adding that the PETM is so crucial because it is a possible window on our own situation. "A lot of carbon indeed injected themselves into the atmosphere during the PETM, and the warming event that followed it lasted more than 100,000 years. Precisely how rapid the emissions occurred is a different matter. Facing The Future "Together with colleagues from the University of California-Riverside and the University of Bristol, researchers examined a deep ocean core of sediment from off the coast of New Jersey in order examined what happened during the PETM. "The research team's goal was to figure out the ratios between different isotopes of carbon and oxygen 56 million years ago. It is important to examine the relationship between the two because it would allow researchers to determine how levels of CO2 in the atmosphere influenced temperatures back then. "Zeebe and his colleagues found that there is a gap between time that massive pulses of carbon went into the atmosphere and subsequent warming, because the oceans have larger thermal inertia. A large lag time would suggest greater carbon release, while the lack of lag time would mean that CO2 came out slowly. "About 2,000 to 4,500 billion tons of carbon possibly injected themselves into the atmosphere during the PETM, and that is equivalent to 1 billion tons of carbon emissions per year. Now, humans are releasing 10 million tons of carbon emissions annually, which are impacting the Earth more rapidly. "What does this mean for our future? The PETM analogy to our own time is less than perfect, but it suggests that our own era is worse than what happened since the dinosaur extinction. "The two main conclusions is that ocean acidification will be more severe, ecosystems may be hit harder because of the [carbon emission] rate," said Zeebe. "This also means that because the carbon emission rate is unprecedented, our planet has effectively entered an era of "no-analog" state, where there is no parallel for the rate of change. It represents a challenge that could constrain future climate projections. "The findings of the study are featured in the journal Nature Geoscience." http://www.techtimes.com/articles/1...h-unprecedented-since-dinosaur-extinction.htm
See, the earth changed and everything turned out alright. Except for the 90% of everything dying thing.
Lol, except for that thing. But since Red Snapper (the real stuff) has become so scarce, why should I care if ocean life dies off, what's in it for me? "My chart shows X and Y alternating, so that means X causes Y!"
and that has nothing to do with oceans being fished out by large nets and power boats and real pollution? We have been saying stop spending billions on fudging temperature data and start working on repopulating and cleaning the oceans.
Just off hand it seems there is a disconnect between the "science" of the PETM, and the James Hansen "Science" of the late twentieth Century. Aren't we getting just a little bit ahead of ourselves here? (see the underlined portion.) Well let's see, if we interpret "possibly" as "did" then our current rate is 5 one millioneth of the lowest emission rate estimate for the PETM. And again, how much did the temperature rise according the educated guesses, 41 deg F. So our temperature should be rising 0.0002 deg F per year. (Ceteris paribis, and assuming that the PETM warming was due to CO2, AND warming is due to CO2 now - an unjustified assumption in both cases of course.) Or alternatively CO2 was an insignificant factor then, and an even less significant factor now. Or CO2 did not matter than, as far as temperature goes, but it sure does matter now. Here is a point I made a long time ago. The paleo record also shows that there were periods when the CO2 was much higher than it is today, yet the temperature was lower than it is today. That's a little problem for Hansen and his boys. Now, Richter, do you understand why I am so skeptical of the Hansen school of "far-too-simple climate science"? There are a lot of knowledgeable people working in this area. Sadly, James Hansen is not one of them -- he's become a charlatan. I think he started out with good intentions, then became emotionally involved and was psychologically unable to backtrack. And even more sadly, the media and politics have combined to make the science an also ran. I am sticking by my earlier prediction that this whole business will eventually become known as "climate gate". And I am going to keep hammering away at you until you finally see the light. You're far too bright to be hanging with the USA today crowd. The Temperature may indeed be going up, the jury is still out, but if it is, it doesn't seem to have anything to do with the increases in our atmosphere's trace CO2 levels. _____________ I believe Ockham's Razor generally holds in science. The most likely cause of fractional degree long term surface temperature increase is direct thermal pollution. Larger increases, or decreases are going to be do to solar, geothermal, plant/animal imbalances or astrophysical phenomena. All climate models virtually ignore the role of the plants; yet plants are 50% , or more , of the total picture!
I don't feel like citing people to these things right now as I have posted them before. 1. the oceans are tuning less base... not acid 2. they are turning most in the indian ocean 3. the indian ocean is where the warming is coming from 4. the warming is probably coming from the vents and volcanoes oceanographers were amazed to find. 5. we have cycled far more in the past where the articles I read have said the water eventually did turn virtually lifeless. (before man). 6. absent any science showing man made co2 is doing this... the yawn is that everything that changes is blamed on man made co2
