There is concrete evidence for evolution in fossils and the fact that we still witness it today.
That's true. Yet somehow there are still many disagreements about what is supposed to be
a theory within the life sciences.
Global warming is also something we can physically observe
Global warming I've spent far more time on than evolution (understanding it is key to humanity in ways that understanding evolutionary processes are not. So let me tell you what we can "observe":
1) We can observe direct temperature readings that barely cover the globe
now, and that since thermometers were developed have been nearly absent for most of even the last 100 years. Which means that global temperature records require advanced statistical techniques just get any global measurements at all.
2) We know, as a fact, that urbanization and various other surface processes completely unrelated to climate change are and have been a heavy influence on the temperature records. HadCRUT, NASA, and a few others who produce the global direct temperature measurements have been trying to adjust for these for years, and they are currently relying on a heavily disputed method developed in the 80s.
3) We know that the best temperature proxy we have is the one developed by two scientists who figured out how to use microwave sounding units of NASA satellites to produce temperature readings farm more accurate than weather balloons, local readings, etc. But there remains a discrepancy between these readings and those that are inferior, because the satellites no not show the tropical dynamics predicted by mainstream IPCC theory. Also, the two individuals who were awarded for their groundbreaking work in developing this temperature proxy, one of whom has not only participated in the IPCC reports but was a 2001 lead author disagree completely with the mainstream view.
4) We know that the entirety of AGW rests upon one thing most of all: a feedback parameter generated by models which are not only trying to replicate one of the most complex natural systems we know of, but are using data that is inaccurate to do so.
5) We know that robustness is a defining characteristic of complex systems like climate, and we don't understand what would constitute so great a change that a phase shift would result.
6) We know that basically every single prediction made has been wrong. The last years have been the hottest on record, but 1) that record is pathetically insignificant, 2) there is no statistically significant difference in our records between the warming that occurred and then flat lined and the warming in the 30s. So we've gone without a statistically significant recorded global warming in the same about of time as we have a statistically significant period of cooling just before.
7) The proxy records are so much of a mess it took an retired Canadian prospector to notice how a proxy reconstruction that was going to be
the feature of the upcoming IPCC was in fact flawed. In the end, that controversy sparked two spate major hearings and remains unresolved.
8) CLOUD at CERN has been investigating another causal explanation for the temperature record we seem to have that involves solar magnetic flux and cloud seeding from galactic cosmic rays.
9) The INI held a conference in 2010 about the utter failure of climate models and what needed to be done. There were not climate "deniers" present, no skeptics, no politicians, just scientists talking about how the models continually fail.
I could go on and on and on, but every time I try to delve into that mess that is climate science, everything from lost records to political scandals gets in the way. But we can say one thing for sure: your "directly observable" conception of this warming is utterly wrong and reflects a completely inadequate representation of how mainstream climate scientists actually produce these records, let alone an accurate statement about the climate.
When you want to make statements about what scientists in some field have as back up, check to make sure you have any idea what you are talking about.
But the universe originating from a black hole?
I said nothing of the sort. I didn't agree with the poster who said that, nor did I include it in my response.
Not only can we not observe it (because the universe already exists),
Which one? Because a common interpretation of quantum physics, which describes all of everything happening all the time, is that it necessitates infinite universes or infinite duplicates of this one with alternate histories. And that has nothing to do with running models backwards.
but there's nothing really solid to support that it did happen.
Do you know what the evidence is?
