Only an idiot would deny climate change. It always has and always will change, because the system is inherently unstable.
The problem arises when people take a very short term view of an obvious correlation and insist that it proves causation, despite all the historical evidence and actual physics. This leads to a comforting delusion that we can somehow avert a disaster that is actually inevitable, by making sacrifices.
Interesting interview with a former Scotland soccer team manager on the radio last week. Asked why they had not reached World Cup rankings for several years, he said "We kept getting drawn against better teams."
Newton did what physicists do: constructed a mathematical model that matched and then predicted actual observations. Nothing to do with quantum mechanics - and quantum gravitation still remains an undemonstrated hypothesis.
The best introduction to quantum mechanics I think is to follow its historical derivation via Planck's explanation of black-body radiation and the photoelectric effect, then to consider how line spectra can occur. This will at least put some "visual" framework in your mind. The conceptual difficulty I found was incorporating Schrodinger's wave mechanics into my thinking but it gets clearer if you approach it from the point of view of stereochemistry (why are molecules the shape they are, and wobbly?). Whatever you do, don't get sidetracked by Schrodinger's cat or anything that smells of philosophy or psychology - it's just physics, chemistry and mathematics.
Seems unlikely that anything that would have been killed inside the egg (max yolk temperature ~ 70°C for hardboiled) would have survived outside at 100°C. I guess the water would taste pretty fowl, though, with a hint of sulfur, chalk, hen's arsewipe and boiled feathers. Perfect palate-cleanser for a wine snob.
"The Russian Federation" does not have a nervous system and cannot be scared of anything. Vladimir Putin, like most politicians, relies on the presence of an enemy in order to justify his salary and divert attention from the corruption and incompetence of his administration. As with Bush, Thatcher, Hitler and Blair, if there is no actual threat, you have to invent one.
When a politician says "we" he means "you", and when he claims to be making decisions in the national interest, he is acting principally in his own interest. The people who benefit from wars are not those who fight them, but those who invent them. At best, a soldier will lose a year or two of family life and business, at worst, his life. But a politician stands to gain re-election at best, and retire with a generous pension at worst.
The DNA test will pretty well identify an individual with odds of misidentification lower than 1:1,000,000, but if you want to know how long he has lived in a particular area, you'd need to look at the isotopic constitution of his teeth or bones, and that is diet-dependent, changes very slowly, and may not distinguish between modern urban environments where food and water may originate from a long way away!.
Sucrose and electrolyte levels vary from minute to minute. At best, you might suspect that your target is diabetic or addicted to "energy drinks" - or maybe just likes salt on his chips.
The natural "ur-chicken" is a social, forest-dwelling bird. Living in a flock, and being well insulated, it has no need to fly very far: they don't migrate, mammalian predators can't fly at all, large avian raptors avoid dense forests, and small raptors (even dogs!) avoid fighting with cockerels. But it does need to sleep off the ground and to take off quickly if attacked by a mammal. So it has evolved to fill an ecological niche.
The domestic chicken is an odd creature in many ways. Most birds lay eggs once or twice a year in a distinct nest and sit on them until they hatch but the free-range farmyard chook lays an egg every day, not always in the same place, and only gets truly "broody" and sits on her eggs once or twice in a lifetime. That said, the bird has been bred to have very large flight muscles (the white bit) and carries very little dead weight (leg bone), so is still capable of rapid takeoff in any direction, even by running downwind (unlike soaring birds).
Horses for courses.

Flight endurance is extremely variable: design or evolution meets specific demands. Thus interceptors like the Me163 could only sustain powered flight for 7.5 minutes whilst solar-powered airplanes have stayed airborne for weeks. Likewise birds vary from pheasants and domestic chickens (30 seconds average) to albatross (2 years).
Pedantically, if you bred an edible bird that could fly for a couple of hours it would be a duck, not a chicken. That is called "evolution of species".
It has been a problem when recovering deep demersal species. IIRC the first complete and live coelocanth was something of a surprise as fishermen had been trawling apparently dead ones for many years and believed the species was actually extinct.
Not significantly. The energy released in an average thunderstorm is equivalent to that of a 20 kiloton nuclear weapon. There are around 2000 thunderstorms in progress at any time, probably 15,000,000 per year, and that's just a small fraction of the daily energy exchange.
Around 2000 nuclear weapons have been exploded in the atmosphere, mostly in the 20 - 100 kt range. Politicians are insignificant in the realm of atmospheric physics, and nobody else has any use for nuclear explosions.
Of course if we allow politics to get out of hand, there is a possibility of a significant "exchange" of nuclear explosives in a short time, leading to a circulating cloud of dust and ash that will eliminate civilised life in the northern hemisphere.
No other species puts its worst members in charge.
Imagine a stream of cars travelling along a straight road.
If they are travelling at 1 m/s and one car passes you every second, they must be 1 m apart.
If they are travelling at 100 m/s and one passes every second, they must be 100 m apart.
Now replace cars with air molecules, and push a simple wing through a "block" of air, maintaining laminar flow over both surfaces. The length of the upper surface is greater than that of the lower, so at any instant the molecules above the wing must be moving faster over the wing, thus further apart than those below.
Molecules squeezed together equals increased pressure, molecules pulled apart equals reduced pressure, so there is a pressure difference across the wing ,resulting in an upward force.
