Reliable measured data are available since 1880
From calibrated measure point sequally distributed accross the globe? I doubt it...
We have truely global measurements only since we have good enough satellites, which is a couple of decades.
your starting post where you seemed to imply there was no climate change at all?
I did not, I just tried to imply that what pretty much the complete Northern Hemisphere is getting now is rather contradictory to global warming. And yes, I know that one winter does not really contradict a trend if it's there, but since pretty much each warm day is now being used to prove global warming I thought I'd use the same trick.
Fact is, that "global warming" is being increasingly hijacked by any and all possible groups to get things their way. Politicians to get extra taxes and have a reason to block the upcoming BIG industries such as China and India, “green” people and organisations to get their fundings (can you imagine Greenpeace admitting they’ve been wrong about global warming if it turns out they are wrong?). Politicians who get green voters talk green, same politicians fund scientific research and are not really interested in any research getting the undesired answers. Scientists want jobs at universities, and researching or teaching the “wrong” things doesn’t get them a job. The Dutch Meteorological Institution has gone so far now as to fire those who do not accept the global warming as it is “taught”. That’s quite Copernican!
Science has a thing called “falsification”. This means you try to disprove any idea or theory, try to find facts that do not fit in the theory. If you do, the theory must be either changed or, in severe cases, be dropped.
Example: if man is causing global warming, the lower atmosphere should heat up first, its affect causing heating in the higher atmosphere (stratosphere) later on. If the cause is cosmic (Sun etc), the heating should go the other way, i.e. down. How doe sit go? Down! In the decade 1990-2000 the Sun was very active, the exosphere and stratosphere heating up (and expanding), and indeed 1995-2005 were warm years. In 2000-2010 the Sun’s activity lowered considerably, the high atmosphere has begun to cool greatly, and, well, look outside (if you’re in the North!). This pattern does not fit the human CO2 warming!
I do not say that there is not a climate change, I say the climate has always been changing! Its just that we have become so very vulnerable to any change that it is affecting us so much! 5cm of snow, and the whole railway system went down for three days here!
I’m much more concerned by the increasing spoillage, wasting ways, aggression, intolerance, arrogance; in short: hubris that, if things go on like this for some years to come, will result in something that will pale any climate change’s results. It’s not the climate that going to be our downfall, but we ourselves. Unless, of course, we’re going, as a collective, to start to use our brains and intelligence and sense of measure and responsibility and what not. Looking at Man’s history, I’m not very optimistic, to put it mildly…
