Comment Re: Really.. Really??? (Score 1) 271

So you're saying this has happened in climate science, and continues, in spite of multiple different source sets of data, teams working on them, and lots of coordination with other proxies, and many different teams working on them? Every study on the subject I've seen has shown the warming trend in spite of instrumental inaccuracies.

So are you claiming that all the studies and correction methods and checking and re-checking and use of non-instrumental proxies have given us wrong results in spite of our best efforts? Or just that we literally can't measure temperature trends accurately at all?

What is your actual claim about climate trends, and where are the studies that back it over the studies that disagree with you?

Temperature changes are causing migration, disease and war, already. That's why it's worth thinking about. Worrying, that's up to you. For example - This is an article about a study that argues that climate change increased the effects of a drought which provided one cause of the Syrian civil war.

Comment Re:Why are land stations used? (Score 1) 271

Satellites measure temperatures in the stratosphere and troposphere, with slightly less accuracy deeper in the atmosphere, iirc. Surface stations measure surface temperatures.

The advantage of surface stations is that we have many more than we need to get statistically accurate, so it's possible and routine to check groups of stations against each other and remove anomalies. Also, the surface record is obviously much longer than the satellite one.

If you want more on ground station accuracy, check out Berkeley Earth. It's a team put together with climate skeptic scientists and others which set out in 2010 to assess the accuracy of global warming claims and the instrumental record. They found that overall the surface temperature records, even from stations rated "poor", recorded the same degree of warming as other sources. Urban heat islands had no real effects on the data because only about 1% of the sensor sites were subject to that effect. And there's more, but it's all pointing in the same direction.

Hope that helps you understand why surface temps are still used and useful.

Comment Re:RAM latency is not getting much faster (Score 1) 92

Replacing hard drives with SSDs still leaves another bottleneck. The disks have to connect to the cpu somehow. If they are internal (as in a home pc), then you only get a few disks, but they connect at PCIe speeds. If you need more disks, you go to a SAN. But then you're putting your disks at the end of *network* latencies; there's definitely a wall there. You can't cache your way out of the transmission delays on the SAN... Other solutions are used which essentially move the software and/or data closer to the hardware.

Comment Causation, CO2 and Warming (Score 5, Insightful) 132

[quote]How do we know the CO2 spikes caused the warming? Perhaps the CO2 resulted from increased biological activity occuring as a result of the warming. [/quote]

CO2 is a warming gas in the atmosphere; in the absence of any other changes, adding CO2 will warm the atmosphere. However, as the article notes, we don't know what caused the quick ramp-up of CO2, and we *do* know that other factors (both cooling and warming) were in play. We also know that over time the atmosphere warmed enough to end the ice age in question.

What is safe to say is that CO2 has a warming effect, which could be counterbalanced *and* added to by other factors. It's the overall balance of these things that tilts the scales one way or another. CO2 is just one piece.

But it's not mistaking correlation for causation to note that adding CO2 to the atmosphere will result in increased warming. That's just basic physics. The fact that it could be offset by something else is immaterial to your point.

That argument that deep austerity is needed is bogus, however. For years, economists and climate scientists and even skeptics have been arguing that whether or not the problem exists (okay, well, now they usually admit it exists), there is an entire new economic sector that can be opened up to private businesses - climate change mitigation. And that is a net *positive* to the global economy, for the economy as well as through the development of new technology. The fact that if bad things are averted we also gain economically from avoiding them is icing on the cake. The downside? All the major fossil fuel industries are looking at a "co-opt or die" scenario. Cui bono?

You can do this without extreme taxation or austerity, IF you start reasonably soon (in the next few years would be good - we passed ideal a few years back). It's the fear and exaggeration of the costs, largely put out by fossil industry interests, that is delaying change.

So if you really do just tune out and think of nutbar extremists when you consider the costs of this, what you're selecting is guaranteed to be the most expensive path through the next few decades. If you're *lucky*, the cost of that will be minimal as thousands of climate scientists are proven to be wrong. But if you're wrong, well.. That's when that choice gets ugly for your kids.

How much are you willing to be that the climate scientists and their peer-review system are so totally corrupt and incompetent that they are completely wrong? Your future, and your kids and grandkids futures? Hey... Go for it. Maybe modern climate science is the equivalent of catastrophe geology up against Alfred Wegener. But... That's a huge bet to make against the professionals.

Where's the hiatus in the warming of the oceans? There's a lot more short term variation in atmospheric warming, but given that the oceans have *not* seen a hiatus, it's clear that that is simply a temporary cooling signal added to the mix. This is what should concern you, because when that cooling signal fades out, the warming in the atmosphere will be back, and possibly at a faster rate than before. In effect, we're getting temporary relief - don't think it's a permanent thing, because if we were really cooling, the oceans would show it unequivocally.

Further, the cite you gave actually reiterates what I'm claiming.

"The growth rates of CO2 concentration have increased in recent years. The distribution of CO2 growth rates differs regionally due to the variation of source or sink. And the spatial variation of CO2 concentration is small compared to that of fluxes. Because the atmosphere is an excellent filter of spatially and temporally varying surface fluxes, integrating short-term fluctuations while retaining the large-scale signal. High growth rate in East Asia has been associated with high growth rate of fossil fuel. And high growth rate in South America is due to decreased biosphere uptake of grass/shrub region in Brazil and increased wildfire release."

"...retaining the large scale signal." That is, the global signal of increasing CO2 is not knocked down by regional or local variations.
