Earth's Temperature at Highest Levels in 400 Years
thatguywhoiam writes "Congress asked, and the scientists have answered: 'The Earth is the hottest it has been in at least 400 years, probably even longer. The
National Academy of Sciences, reaching that conclusion in a broad review of scientific work requested by Congress, reported Thursday that the 'recent warmth is unprecedented for at least the last 400 years and potentially the last several millennia.'"
There was a mini-ice age in the 1700's believed to be related to lower solar activity. All this means is we have returned to pre-mini-ice-age temperatures. I don't know of anyone that does not accept global warming (as in the warming of regions of the earth). I know a lot of people which can't agree on the causes. Temperatures were warmer 1000 years ago. The reason the vikings were so active from Norway was that they had mild temperatures up there, warmer than now. Cyclical Global warming != greenhouse effect. Greenhouse gases effect may play a part, but the biggest variable (the sun) is not yet being realistically tracked.
Here's to losing my Karma Bonus again....
The 1600s were smack in the middle of the little ice age. The study doesn't say it was this warm 400 years ago. It says that with 400 years worth of data, this is the hottest period observed. Proxy studies and urban heat island effects cloud the results of all such studies. Another way to look at this: The Earth has fully recovered from the Little Ice Age period. Horray! Warmer is far better than colder. The 1600s will go down in European history as among the worst times. Famine from crop failures. Diseases were epidemic.
Unfortunately for us all, on matter who is right, and who is wrong, the "experts" and the "leaders" will argue it until we're all dead.
It's well past the time that we pick a problem, and all attempt to fix it.
We can all clearly that noxious emissions are a problem. In some parts of the world, they've pushed the oxygen levels in the atmosphere down to almost unsurvivable levels. Producing lethal chemicals and dumping them into the environment is also clearly bad.
Depsite these obvious problems that we continue doing, we'll argue the finer points of theory until we're dead.
Hell, what's the worst that cleaning up would do? Cleaner air and water? I wouldn't complain.
Many countries agree that there's a problem, and want to fix it. Read up on the Kyoto Protocol. The #1 producer in carbon emissions is also one of the two countries who have refused to agree to the protocol.
Token things are done to clean up the air. For example, passenger cars were required to meet stricter requirements. Unfortunately, trucks and SUV's don't fall into the same rules. Marketing went heavy into putting every Joe-Consumer and soccer mom into a SUV. There's bigger money in oil than there is in clean air.
Serious? Seriousness is well above my pay grade.
Not scientifically proven? I don't care what Rush Limbaugh has been telling you... Among scientists that study climatology and related fields there's an overwhelming consensus. Those rare exceptions are typically shills being paid off by Exxon-Mobil. See http://exxonsecrets.com/ and take a look at the ulterior motives of your favorite skeptics.
Ask me about my sig!
You should link people some of these reports to read, preferably by reputable scientists who research the subject...infact, let me clarify that last part:
Reputable as in not politically biased (ie, Al Gore would certainly not be reputable), published multiple papers on the subject and/or adjacent subjects in notable Journals (ie, Nature, Science, whatever, not "Wicca Quarterly," "The Limbaugh Letter," or other nonsense), and preferably a resident at a University (not their Mom's basement). Knowing who funds the research is a big plus.
And of course, by scientist, I mean people who actually, you know, do science. Not some quasi-science bullshit like most people injest and take as the truth, either. The person better have cited his sources, included his scientific data (and not summarized it like a fucking news paper article), and lastly, included error analysis. No PhD = not a reputable scientist. This isn't Coast to Coast.
I have not read any serious reports on the subject. I've heard PLENTY of media spin to the point where I wouldn't believe the truth if they told it to me. It's pretty easy to do a google search and find about 10^6 links from unqualified bloggers, cheesy geocities pages, and your typical array of leftist banter, all claiming the sky is falling but never citing just who determined that. Last time I checked, I'd file under the category of "ignorant" with most of the world (even if they don't believe it.)
Finally, let me say this (and recall I've already admitted my ignorance of the subject): I question just how accurately temperatures from 2000 years ago can be measured, relative to, say, satellite technology now. If the global mean temperature has increased 3C (and from I've heard it's less than that...) and your error is +/-5C then just how useful is that data?
Hypothetical question for you, You're crossing a road, first thing in the morning. You're still maybe half asleep, late night and all that.
Suddenly you hear a noise. You look up from your reverie to find there's a huge great truck barrelling down the road toward you, horn blaring.
So what do you do? Do you think "Hmm, this is an rare scenario. The truck could exist, but I also have to consider that I may in fact be still asleep and dreaming this encounter. What data can I collect to determine if actiion is truly warranted in this case?"
Do you do all that, or do you get out of the frigging way first and then run your analysis? I bet I know what most of your ancestors did in analagous situations.
See, the thing is that science never proves anything. That's not a flaw in science, it's methodology. Scientists have long discarded modus ponens as the logical basis for the scientific method, in favour of modus tollens. What that means is that we don't try to prove things, because we recognise that we may not yet have all the facts. Instead we propose a explanation that seem to fit the facts and we try and disprove it.
The thing to note here is that if e wait for science to prove that global is happening, we'll still be waiting in billions of years time. Even if the Sun the should expand to swallow the earth and engulf us solar plasma, we;ll still be waiting, because that's not what scientists, do!
What they do do[1] is get out of the way of oncoming traffic.
If you want to be scientific about this, you need a counter theory, and it has to be falsifiable. There has to be a test we can conduct that to prove it wrong. Preferably one that doesn't involve waiting a thousand years to see if the climate flips state back to the Cambrian Era.
Give me a set of criteria that, if they are satisfied, you will regard as sufficent evidence for taking action against global warming and I will accept that you may have a pont. Otherwise, all you're doing is saying "Bah! Youse scientist dunt never nothing nowhow" only in an fancy accent.
Me, I vote we get out of the way of the truck
[1] On the whole, that is. I'm not counting absent mindedness, scientific tests of experimental traffc-proof suits, or Bruce Banner when he gets angry. I don't really think this weakens my argument.
Don't let THEM immanentize the Eschaton!
